According to an aspect of the embodiment of the present application, there is provided a method for acquiring area data, optionally, as an optional implementation manner, the method for acquiring area data may be applied, but is not limited to, in an environment as shown in fig. 1. Which may include, but is not limited to, a user device 102 and a server 112, which may include, but is not limited to, a display 104, a processor 106, and a memory 108, the server 112 including a database 114 and a processing engine 116.

The specific process comprises the following steps:

step S102, the user equipment 102 obtains a trigger instruction for sending an area data request;

step S104-S106, the regional data request is sent to the server 112 through the network 110;

Step S108, the server 112 responds to the area data request and determines target tiles with matched target geographic positions from a tile cache list through a processing engine, wherein the tile cache list comprises a plurality of tiles, each tile in the plurality of tiles is used for caching area information associated with each geographic position in a target geographic area, the plurality of tiles comprise target tiles, and the target geographic area comprises target geographic positions;

step S110, the server 112 obtains target area information of the target tile cache through the processing engine, and determines the target area information as area information associated with the target geographic position;

Steps S112-S114, the area information associated with the target geographic location is sent to the user equipment 102 through the network 110, the user equipment 102 uses the area information to perform the acquisition of the area data through the processor 106, and the acquired area data is displayed on the display 108, and the acquired area data is stored in the memory 104.

In addition to the example shown in fig. 1, the above steps may be performed by the client or the server separately, or by a combination of the client and the server, such as by the user device 102 performing the above steps of determining a target tile from a tile cache list that matches a target geographic location, thereby relieving the processing pressure of the server 112. The user device 102 includes, but is not limited to, a handheld device (e.g., a mobile phone), a notebook computer, a desktop computer, a vehicle-mounted device, etc., and the application is not limited to a particular implementation of the user device 102.

Optionally, as an optional implementation manner, as shown in fig. 2, the method for acquiring the area data includes:

S202, acquiring an area data request, wherein the area data request is used for requesting to acquire area information associated with a target geographic position;

S204, responding to the area data request, and determining target tiles with matched target geographic positions from a tile cache list, wherein the tile cache list comprises a plurality of tiles, each tile in the plurality of tiles is used for caching area information associated with each geographic position in a target geographic area, the plurality of tiles comprise target tiles, and the target geographic area comprises target geographic positions;

s206, acquiring target area information of the target tile cache, and determining the target area information as area information associated with the target geographic position.

Alternatively, in this embodiment, the above-mentioned method for acquiring regional data may be applied, but not limited to, in a context of caching recommended content, where the recommended content may include, but is not limited to, data content for recommending services to a user, for example, recommending restaurant services in a certain range to an automobile user, recommending medical services in a certain range to a resident user, recommending a movie and television play in a current time slot to a chasing user, and so on.

Optionally, when the user initiates the request for acquiring the recommended content, in order to improve the timeliness of the feedback of the recommended content, a caching technical scheme of the recommended content may be adopted, but is not limited to the method. And receiving a request for acquiring the recommended content by using a downstream service interface based on the position parameter, responding, determining the recommended content corresponding to the request from the cache of the recommended content, and returning.

Optionally, the caching of the recommended content is implemented using a downstream service interface based on the location parameters, including: a caching mode based on a fixed preset value and a caching mode based on a user identifier.

It should be noted that, based on the caching manner of the fixed preset value, when the downstream service interface is not available, there is a defect that the returned recommended content is inconsistent with the recommended content acquisition request initiated by the user. For example, when a user initiates a request for recommending restaurants to the whole country, the downstream service interface cannot normally return a list of restaurant recommendation to the whole country, but can return a list of restaurant recommendation to Beijing, which is already preset, if the downstream service interface is not available.

It should be noted that, based on the caching manner of the user identifier, the effect of returning the corresponding recommended content can be achieved for the recommended content acquisition request sent by the existing online user when the downstream service interface is unavailable. But in case the downstream service interface is not available, it is still unusable for the newly accessed user. And, based on the caching mode of the user identifier, a larger caching space is needed, and the load pressure on the whole service is larger. And, in the case where the downstream service interface is available but the request traffic that the downstream service interface can carry is small, the improvement of the quality of service of the recommended content by the caching of the recommended content is not obvious, and the adjustability of the request traffic to the downstream service interface is poor.

It can be understood that, for acquiring the recommended content, the acquiring request of the recommended content is directly sent to the downstream service interface based on the position parameter, then the downstream service interface responds, and returns the corresponding recommended content, so that the corresponding recommended content cannot be normally returned when a large number of users access the service and the downstream service has insufficient bearing capacity, and a long time is required to wait until the downstream service interface returns to be normal, and then the recommended content returned by the downstream service interface can be successfully acquired, thereby causing the problem that the acquiring efficiency of the recommended content is lower to occur.

Optionally, the method for acquiring the area data includes: acquiring a recommended content request, responding to the recommended content request, determining a matched target tile from a tile cache list, acquiring and determining target recommended content information cached by the target tile as recommended content information corresponding to the recommended content request.

It should be noted that, the above method for acquiring the region data may be, but not limited to, a tile-based cache technical scheme.

Optionally, the first geographical location area is divided into a plurality of tiles with the same length and width in advance, and coordinates of the respective tiles are specified. Each tile corresponds to one or more caches that are associated with geographic location content within the range. When a large number of users access the service and the downstream service has insufficient bearing capacity, corresponding tiles are calculated through the geographic positions of the users. And randomly selecting a certain cache corresponding to the tile. The tiles can be divided into multiple stages, and the length and width of each stage are different, so the coverage is different. The higher the tile level, the wider the coverage, and the highest level may cover the largest range of geographic location areas. So if when a tile does not find a cache, it can be searched in the previous level until a suitable cache is found. And finally, returning the cache to the user.

By using the method for acquiring the regional data, a plurality of users related to the positions can share the same cache, and the method is equivalent to the existing online users and newly accessed users. This enables the pressure on downstream services to be quickly reduced in a short time after the buffering of a plurality of user-dense areas is set by automatic updating. The applicable area of the cache is increased, and the required cache space can be reduced. Because the recommended data taken by the user has a strong correlation with the user's current location, there is little perception by the user in the event of such service degradation. In addition, by setting the number of levels of tiles, the flow rate to downstream services can be adjusted. The more the number of levels of the tile layer, the greater the tile cache hit rate and the fewer the number of times that downstream services need to be accessed.

It can be understood that by using the above method for acquiring the area data, not only is the decoupling of the area information and the downstream service interface realized, but also a manner of caching different area information by using different tiles is realized, and accurate area information is provided for the user, so that whether the area information acquisition and the downstream service interface are normally associated is smaller, even if a large number of users initiate requests for acquiring the area information to access the service and the downstream service bearing capacity is insufficient, the corresponding area information can be normally returned, and further, the purpose of overcoming the limitation of the area information acquisition process on the number of requests for the user access is achieved, and the technical effect of improving the area data acquisition efficiency is realized.

The method for acquiring the regional data can be applied to the scene of acquiring the recommended content, can realize decoupling of the recommended content and a downstream service interface, and can improve the acquiring efficiency of the recommended content by caching different recommended content by using different tiles, and solves the problem of lower acquiring efficiency of the recommended content.

Optionally, in this embodiment, the area data request is used to request to obtain area information associated with a target geographic location, where the target geographic location may be, but is not limited to, a geographic location currently located by a user initiating the area data request, and may be, but is not limited to, a geographic location preset by the user initiating the area data request.

Alternatively, in the case where the user changes the target geographical position from the a position to the B position through the position operation interface 3004 shown in (a) in fig. 3, as shown in (B) in fig. 3, a third button 306 for instructing the user to initiate a nearby food viewing request corresponding to the target position, and a fourth button 308 for instructing the target geographical position (B position) are included in the nearby food viewing interface 3006.

Optionally, in this embodiment, the tile cache list may be used, but is not limited to, for storing a plurality of tiles, wherein each tile in the plurality of tiles may be used, but is not limited to, for caching area information associated with each geographic location within a target geographic location area, the target geographic location area including a secured geographic location.

Alternatively, in this embodiment, the tiles may be, but are not limited to, square grid pictures cut into rows and columns of a map in a scale or scale according to a certain size and format.

Alternatively, in the present embodiment, before the region data request is acquired, the target geographic location region may be divided into a plurality of tiles with the same length and width in advance, geographic location coordinates associated with each tile are specified, and the plurality of tiles are stored in the tile cache list.

Optionally, in this embodiment, after the area data request is acquired, a tile with a preset size may be generated based on, but not limited to, the geographic location information carried in the area data request, and the tile is stored in the tile cache list.

Optionally, in this embodiment, the area information associated with the geographic location stored in the tile may, but is not limited to, include a plurality of cache records, where the plurality of cache records may, but is not limited to, be stored by way of a cache record list.

Optionally, in this embodiment, after the target tile matching the target geographic location is acquired, target area information of the target tile cache is acquired, and the target area information is determined as the area information associated with the target geographic location. Wherein the target area information may be, but is not limited to, a target cache record in a cache record list in the target tile.

Optionally, in this embodiment, the target cache record may be, but is not limited to, the latest cache record in the cache record list, where the plurality of cache records in the cache record list may be, but is not limited to, ordered based on time information associated with the cache records.

Optionally, in this embodiment, the target cache record may be, but is not limited to being, the largest cache record in the cache record list, where the plurality of cache records in the cache record list may be, but is not limited to, ordered based on the content associated with the cache record.

Alternatively, in this embodiment, the target cache record may be, but is not limited to being, a random cache record in a cache record list, where a plurality of cache records in the cache record list are randomly ordered.

By way of further example, as shown in fig. 4, an alternative region data acquisition method includes:

step S402, obtaining an area data request, wherein the area data request is used for requesting to obtain area information associated with a target geographic position, such as the area information of 'looking over food near the B position' displayed by the area data request interface 402;

Step S404, in response to the area data request, determining a target tile from a tile cache list, wherein the tile cache list comprises a plurality of tiles, each tile in the plurality of tiles is used for caching area information associated with each geographic position in a target geographic area, the plurality of tiles comprises a target tile, and the target geographic position area comprises a target geographic position, such as a plurality of tiles, including a tile A, a tile B, a tile C, a tile D, and the like, displayed in the tile cache list interface 404;

Step S406, in the case of determining the target tile, obtaining target area information of the target tile cache, e.g. after determining that "tile a" is the target tile in the tile cache list interface 404, further displaying a plurality of cache records stored in "tile a" in the cache record list interface 406, including a plurality of cache records such as "cache record a", "cache record b", "cache record c", "cache record d", etc.;

in step S408, the target area information of the target tile cache is determined as the area information (the area information corresponding to the area data request) associated with the target geographic location.

It should be noted that, in this embodiment, the acquiring and responding modes of the area data request are not limited, the display modes of the interfaces are not limited, and the tile ordering mode in the tile cache list and the cache record ordering mode in the cache record list are not limited.

According to the embodiment of the application, the regional data request is used for requesting to acquire the regional information associated with the target geographic position; determining target tiles with the matched target geographic positions from a tile cache list in response to the regional data request, wherein the tile cache list comprises a plurality of tiles, each tile in the plurality of tiles is used for caching regional information associated with each geographic position in a target geographic region, the plurality of tiles comprise the target tiles, and the target geographic region comprises the target geographic positions; acquiring target area information of the target tile cache, and determining the target area information as area information associated with the target geographic position;

The method for caching the area data by using the tiles can normally return the corresponding area information, thereby achieving the purpose of overcoming the limitation on the number of requests accessed by the user in the area information acquisition process, and further achieving the technical effect of improving the area data acquisition efficiency.

As an alternative, after obtaining the area data request, the method further includes:

It should be noted that, after the area data request is acquired, the target tile and the target area information of the target tile cache may be determined from the tile cache list, and the target area information of the target tile cache may be determined as the area information associated with the target geographic location requested to be acquired by the area data request, which is not limited to the area data request.

After the area data request is acquired, the area data request may be, but is not limited to, sent to a downstream service interface, and the downstream service interface may retrieve the area information associated with each geographic location in the target geographic location area, and receive and determine the downstream service area information associated with the target geographic location returned by the downstream server as the area information associated with the target geographic location requested to be acquired by the area data request.

Optionally, in this embodiment, after receiving the downstream service area information associated with the target geographic location returned by the downstream service interface, a new tile with the target geographic location matching is created in the tile cache list, and the downstream service area information is cached to the new tile.

When the target tile cannot be determined from the tile cache list, the region data request is forwarded to the downstream service interface, the downstream service interface obtains the corresponding region information and returns the region information, and then the region information is updated to the tile cache list.

It should be noted that, in the case where the tile cache list is set to initially divide the target geographic area and create all initial tiles corresponding to the divided area, the above area information is directly stored in the initial tiles whose target geographic positions are matched in the form of cache records.

It should be noted that, in the case that the tile cache list is not initially created with all initial tiles, after receiving the downstream service area information associated with the target geographic position returned by the downstream service interface, a new initialization tile matching the target geographic position is created in the tile cache list in real time, and the area information is stored in the initial tile in the form of cache records.

For the tile which does not initially meet the target condition, under the condition that the cache area information is updated by using the downstream service area information for N times, the number of records stored in the tile is greater than or equal to a preset number threshold corresponding to the target condition, so that the cache area information of the tile meets the target condition, and after receiving an area data request corresponding to the geographic position of the tile, the cache record information stored in the tile can be directly used for returning the corresponding area data.

Step S604, in response to the area data request, searching a target tile with a matched target geographic position from the tile cache list;

Step S606, judging whether a target tile exists in the tile cache list;

It should be noted that, the area data stored in the downstream service interface has smaller association with time factors and higher accuracy, but has larger association with the number of requests sent by the user, and is easily affected and limited by external load pressure and self-bearing capacity.

It should be noted that, through the overall combination of the two types of area data acquisition modes of the downstream service interface and the tile cache list, the downstream service interface returns the corresponding area data when the downstream service interface has a normal bearing state, and the tile cache list returns the corresponding area data when the downstream service interface has an abnormal bearing state. Therefore, under the condition that high load pressure does not exist in the whole service, the accuracy of regional data acquisition is guaranteed through a downstream service interface mode, and under the condition that high load pressure exists in the whole service, the efficiency of regional data acquisition is guaranteed through a tile cache list mode.

It should be noted that, the cache records in the plurality of tiles including the first tile 702 may, but are not limited to, update the obtained new cache records to the corresponding tiles in the process of obtaining the area data by using the downstream service interface.

It should be noted that, the geographic location corresponding to the third tile 706 may be, but is not limited to, a geographic location including the second tile 704, as shown in fig. 7, and the grade value corresponding to the third tile 706 is smaller than the grade value corresponding to the second tile 704. It will be appreciated that in determining tiles that meet the area output condition, the geographic location corresponding to the next tile includes the geographic location corresponding to the previous tile, and the rank value corresponding to the next tile is less than the rank value corresponding to the previous tile.

It should be noted that, the geographic location corresponding to the third tile 706 may also include, but is not limited to, a target geographic location corresponding to the first tile 702, and a target geographic location having an intersection with the second tile 704, and the grade value corresponding to the third tile 706 is equal to the grade value corresponding to the second tile 704. It will be appreciated that in determining tiles that meet the area output condition, the geographic location corresponding to the next tile and the geographic location corresponding to the previous tile have at least an intersection portion of the target geographic location, and the rank value corresponding to the next tile is equal to the rank value corresponding to the previous tile.

It should be noted that, each tile may, but is not limited to, correspond to a tile level, and the tile level may, but is not limited to, be used to indicate the region range information corresponding to the tile. The higher the tile level, the smaller the area range to which the tile corresponds, and the fewer the number of corresponding geographic locations.

According to the embodiment provided by the application, the first tile matched with the target geographic position is searched from the tile cache list, wherein the first tile is used for caching the first area information associated with the target geographic position; searching a second tile matched with the target geographic position from a tile cache list under the condition that the first tile does not meet the regional output condition, wherein the second tile is used for caching second regional information associated with at least two geographic positions, and the at least two geographic positions comprise the target geographic position; and determining the second tile as a target tile in the case that the second tile meets the region output condition, wherein the target region information comprises second region information. By setting tiles with different area ranges and using a hierarchical progressive tile searching mode, the target tiles meeting the area output conditions are obtained, and the purpose of improving the obtaining efficiency of the target tiles is achieved, so that the technical effect of improving the obtaining efficiency of area data is achieved.

s1, sending a region data request to a downstream service interface under the condition that a first tile does not meet a region output condition;

S2, under the condition that the downstream service area information is received, updating the cache of the tile cache list to the target geographic position by utilizing the downstream service area information;

s3, under the condition that failure information returned by the downstream service interface is received, searching a second tile from the tile cache list; in the event that the first tile satisfies the region output condition, the second tile is determined to be the target tile.

Optionally, in this embodiment, in a case where the first tile does not meet the area output condition, an attempt is made to call the downstream service interface to acquire the downstream service area information.

Optionally, in this embodiment, in the case of calling the downstream service interface and receiving the downstream service area information, area information associated with the target geographic location corresponding to the area acquisition request is determined based on the downstream service area information, and the downstream service area information is updated into the corresponding tile in the tile cache list in the form of a new cache record.

Optionally, in this embodiment, in the case of calling the downstream service interface and returning the failure information, a second tile is searched from the tile cache list, where a geographic location corresponding to the second tile includes a target geographic location corresponding to the first tile.

It should be noted that, in the case where the second tile does not meet the area output condition, the second tile may, but is not limited to, attempt to call the downstream service interface again to obtain the downstream service area information.

It should be noted that, the number of user access requests corresponding to the downstream service interface is time-efficient, and the call results corresponding to the downstream service interface are different in different time periods.

It should be noted that, in the case that the second tile does not meet the area output condition, the third tile may be searched from the tile cache list, until the target tile that meets the area output condition is searched, where the geographic location corresponding to the third tile includes the target geographic location corresponding to the first tile, and the third tile may be in an inclusion state with the second tile, or may be in an intersection state with the second tile.

By way of further example, as shown in fig. 8, an alternative method for acquiring region data includes the steps of:

Step S802, under the condition that target tiles with matched target geographic positions exist in a tile cache list, acquiring target tiles and area information of target tile caches;

Step S804, judging whether the region information meets the region output condition;

Step S806, returning the region information of the target tile when the region information meets the region output condition;

step S808, sending the area data request to a downstream service interface when the area information does not meet the area output condition;

Step S810, obtaining and judging a return result of the downstream service interface response;

Step S812, receiving downstream service area information which is returned by the downstream service interface and is associated with the target geographic position, determining the downstream service area information as the area information which is associated with the target geographic position, and updating the tile list as a return result when the return result indicates success;

Step S814, in case the returned result indicates failure, searching for a new target tile with a matched target geographic position from the tile cache list, wherein the new target tile is used for caching area information associated with at least two geographic positions including the target geographic position; returning to step S802, the above steps are repeatedly executed until the request result is returned.

According to the embodiment provided by the application, under the condition that the first tile does not meet the regional output condition, a regional data request is sent to a downstream service interface; under the condition that the downstream service area information is received, updating the cache of the tile cache list to the target geographic position by utilizing the downstream service area information; under the condition that failure information returned by a downstream service interface is received, searching a second tile from a tile cache list; in the event that the first tile satisfies the region output condition, the second tile is determined to be the target tile. Under the condition that the first tile does not meet the regional output condition, the corresponding regional information is tried to be determined based on the downstream service interface, and the defect that the target tile cannot be determined by the clock due to multiple hierarchical degradation is avoided in a downstream service auxiliary mode, so that the purpose of improving the regional information acquisition efficiency is achieved, and the technical effect of improving the regional data acquisition efficiency is achieved.

As an alternative, during or after determining, from the tile cache list, a target tile whose target geographic location matches in response to the region data request, the method further includes:

s1, sending an area data request to a downstream service interface under the condition that the area data request meets a random update condition;

s2, receiving downstream service area information;

After acquiring the target area information of the target tile cache and determining the target area information as the area information associated with the target geographic position, the method further comprises:

And S3, updating the target area information by using the downstream service area information.

Alternatively, in the present embodiment, the region data request has a probability of triggering a random update condition, the probability including a real number of 0 to 1.

Optionally, in this embodiment, in a case where the area data request does not have a corresponding target tile, the probability of acknowledging that the area data request triggers a random update condition is 0.

Optionally, in a case where the area data request satisfies that a corresponding target tile exists, and in a case where the area data request triggers a random update condition, sending the area data request to a downstream service interface, receiving downstream service area information, and after determining the target area information as area information associated with the target geographic location, updating the target area information with the downstream service area information.

It should be noted that, a random silence update mechanism is adopted, so that the cache can be refreshed relatively timely. After the user's request hits the cache, there is a probability that asynchronous refreshing of the cache is triggered. And under the asynchronous refreshing condition of triggering the cache, calling a downstream service interface based on the background silence request, and refreshing the cache record or random one cache record of the tile corresponding to the user request in the tile cache record list by using the acquired data.

According to the embodiment provided by the application, the regional data request is sent to the downstream service interface under the condition that the regional data request meets the random updating condition; receiving downstream service area information; the target area information is updated with the downstream service area information. By means of an asynchronous random silent updating mechanism, the purpose of updating the tile cache list is achieved, accuracy of obtaining the area data is improved, extra obtaining operation of the area data caused by failure of tile cache records is reduced, and therefore the technical effect of improving obtaining efficiency of the area data is achieved.

As an alternative, the method further comprises:

s1, creating a third tile, and caching the third tile into a tile cache list;

After creating the third tile and caching the third tile into the tile cache list, the method further comprises:

S2, setting the third tile to be in an invalid state under the condition that the current time reaches the preset expiration time of the third tile;

s3, under the condition that the data request associated with the geographic position matched with the third tile is acquired, the data request associated with the geographic position matched with the third tile is sent to a downstream service interface;

And S4, receiving target downstream service area information which is returned by the downstream service interface and is associated with the target geographic position, and determining the target downstream service area information as the geographic position associated area information matched with the third tile.

Alternatively, in the present embodiment, the creation of the third tile may, but is not limited to, indicate that the tile cache list is set to initially partition the target geographic area and create all initial tiles corresponding to the partitioned areas.

Optionally, in this embodiment, the creation of the third tile may also, but not limited to, indicate that, in a case where the tile cache list is not initially created with all the initial tiles, a new initialization tile matching the target geographic location is created in the tile cache list in real time, for example, after receiving the downstream service area information associated with the target geographic location returned by the downstream service interface, the third tile is created, and the area information is stored in the third tile in the form of a cache record.

Optionally, in this embodiment, each newly created tile is set to an expected expiration time, where the tile is set to be in an invalid state if the current time reaches a preset expiration time of the tile.

In addition, when a data request associated with a geographic position for requesting to acquire the third tile matching in an invalid state is acquired, the data request associated with the geographic position for acquiring the third tile matching is sent to a downstream service interface; and receiving target downstream service area information which is returned by the downstream service interface and is associated with the target geographic position, and determining the target downstream service area information as the geographic position associated area information matched with the third tile.

By the embodiment provided by the application, a third tile is created and cached in the tile cache list; setting the third tile to be in an invalid state under the condition that the current time reaches the preset expiration time of the third tile; under the condition that a data request associated with the geographic position for requesting to acquire the third tile matching is acquired, transmitting the data request associated with the geographic position for acquiring the third tile matching to a downstream service interface; and receiving target downstream service area information which is returned by the downstream service interface and is associated with the target geographic position, and determining the target downstream service area information as the geographic position associated area information matched with the third tile. On one hand, the expiration time is set for each newly-built tile, so that the aim of guaranteeing the timeliness of the area data cached in the tile is fulfilled, and the aim of improving the acquisition accuracy of the area data is fulfilled; on the other hand, for the outdated tiles, the corresponding area data is acquired through the downstream service interface, so that the flexible purpose of improving the acquisition of the area data is achieved, and the technical effect of improving the acquisition efficiency of the area data is achieved.

As an alternative, before determining the target tile with the matching target geographic location from the tile cache list, the method further includes:

S1, determining character string numbers corresponding to all tiles in a plurality of tiles based on all geographic positions in a target geographic area, wherein the character string numbers are used for recording arrangement positions of all tiles in a tile cache list;

S2, determining a target character string number corresponding to the target geographic position;

S3, obtaining a target arrangement position corresponding to the target character string number;

s4, determining the tiles in the target arrangement position in the tile cache list as target tiles.

Optionally, in this embodiment, the target string number may be used, but not limited to, a tile level and a geographic location corresponding to the target tile, and may be used, but not limited to, to indicate an arrangement position of the target tile in the tile cache list.

Optionally, in this embodiment, longitude and latitude corresponding to the user position are converted into x-y integer coordinates based on Java language, so that a conversion from longitude and latitude coordinates to rectangular coordinates is established, and mapping from the user position to tile coordinates is achieved.

Optionally, in this embodiment, each tile in the tile cache list corresponds to a tile level, where the tile level may be, but is not limited to, area range information indicating that the tile corresponds to. The higher the tile level, the smaller the area range corresponding to the tile, and the smaller the corresponding area range.

Further by way of example, as shown in fig. 9, the user location 902 is used to indicate longitude and latitude coordinate information "23.45224, 119.5653" of the user, and the mapped corresponding tile coordinates 904 are used to indicate coordinate location information of the tile "(453, 124)" and corresponding area location information "(2.44 km )".

It should be noted that the location of the user is specific to which tile corresponds, and is related to both the location of the user and the rank of the tile. If an upper accuracy limit of 0.153km is specified, then the tile level may range from level 18 to level 0, with smaller numbers mapping larger latitude and longitude ranges. And, defining a level up, the tile number is reduced by 1. So that the side length of the tile is doubled for each stage upwards, and the covered area is doubled for 4 times. Wherein the class 0 tiles can cover the entire earth.

Further by way of example, as shown in FIG. 10, a first tile 1002 corresponds to a 14-level tile, corresponds to a geographic area range of 2.44km side, a second tile 1004 corresponds to a 13-level tile, corresponds to a geographic area range of 4.88km side, and a third tile 1006 corresponds to a 12-level tile, corresponds to a geographic area range of 9.76km side. Wherein the geographic area range corresponding to the third tile 1006 includes the geographic area range corresponding to the second tile 1004, and the geographic area range corresponding to the second tile 1004 includes the geographic area range corresponding to the first tile 1002.

Alternatively, in this embodiment, the string number of the tile may be, but is not limited to, determined by the latitude and longitude position of the user and the level of the tile, and the string number has uniqueness.

Optionally, in this embodiment, tile coordinate information of the tile is determined based on the input longitude and latitude information, and the character string code is obtained by conversion based on the tile coordinates and the tile level.

Further by way of example, as shown in fig. 11, based on the input latitude and longitude information, the tile coordinates corresponding to the first tile 1102 are determined to be "(1342, 4354)", the rank information "14" of the tile is appended after the coordinates are generated, the string codes "14-1342-4354" are generated, and the string codes "14-1342-4354" are buffered in the tile buffer list by means of hash arrangement.

It should be noted that, the character string coding form is convenient for reading and hash arrangement, which is beneficial to improving the speed of searching tiles and reducing the size of the space occupied by tile storage.

Based on the above arrangement, the tile number may be used as a key of redis, and the value may be a cache list, but not limited to a cache key storage scheme using redis. After the user requests, the tile numbers can be calculated by obtaining the coordinates of the user, and then the tiles are quickly positioned to the cache by using the redis by using the numbering mechanism. Wherein the search time complexity of the tile cache does not increase with an increasing number of tiles.

Optionally, when requested by the user, the location of the corresponding tile in the cache is calculated based on the user location. And if the corresponding tile exists in the cache, the content corresponding to the tile key is fetched from the cache. If there is no corresponding tile, the downstream service interface is requested, a new tile is created, and the content returned by the downstream service interface is added to the tile. Wherein each newly created tile is provided with an expiration time.

It should be noted that, for tile storage, a method of simultaneous storage and multi-level search in all levels is adopted to increase the cache hit rate. A level range may be, but is not limited to, specified prior to establishing the tile cache, such as a tile level range of 10 to 14. When the current user coordinate is used for requesting the downstream service interface and successfully returning, the returned value is used as a cache record and is simultaneously stored in a 10, 12, 13 and 14-level tile cache record list corresponding to the coordinate. At the next search by the user, if the level 14 tile search is not completed, go to the level 13 tile search until the range maximum is searched or reached. Based on the arrangement mode, multiple levels of tile caches can be stored simultaneously and mutually complemented in the same redis database instance without mutual influence. By adjusting the grade range, the hit rate can be adjusted, the flow of the downstream interface is controlled, and the pressure of the downstream interface is effectively relieved, so that the waste is avoided.

Alternatively, the content of the tile cache may take the form of a list, multiple cache records may be stored, and for a list of cache records for a tile, the number of best cache records it stores may be set, but is not limited to. As shown in fig. 12, when there are cache records in the list and the optimal number is reached, step S1212 may be performed, but not limited to, to randomly fetch a cache record, and return after some processing according to the specific service. If there are cache records, but the number of cache records is less than the optimal number requirement, step S1216 may be performed, but is not limited to, attempting to request the downstream service interface, adding the data corresponding to the request to the list of cache records if successful, and returning to the user. If the request fails, an existing cache record is selected randomly and returned. Thus, the diversity of the cache contents is guaranteed to a certain extent. If no cache record exists, step S1220 may be performed, but is not limited to, attempting to request a downstream service interface and creating a tile cache.

According to the embodiment provided by the application, the character string numbers corresponding to the tiles in the plurality of tiles are determined based on the geographic positions in the target geographic area, wherein the character string numbers are used for recording the arrangement positions of the tiles in the tile cache list; determining a target character string number corresponding to the target geographic position; acquiring a target arrangement position corresponding to a target character string number; the tile in the tile cache list at the target placement location is determined to be the target tile. Based on the establishment of the character string numbers, the reading and the Hash arrangement are convenient, the tile searching speed is improved, the space occupied by tile storage is reduced, the purposes of improving the acquisition speed of the regional data and the storage space utilization rate of the regional data are further achieved, and therefore the technical effect of improving the acquisition efficiency of the regional data is achieved.

Optionally, the above method for acquiring area data is applied to a scenario where the tile cache reduces the background server pressure, as shown in fig. 13, and specifically includes the following steps:

step S1302, obtaining an area data request, wherein the area data request is used for requesting to obtain area information associated with a target geographic position;

Step S1304, judging that the bearing state of the downstream service interface is a normal state or an overload state;

step S1306, when the bearing state of the downstream service interface is a normal state, sending a region data request to the downstream service interface;

Step S1308, when the bearing state of the downstream service interface is an overload state, sending an area data request to a tile caching module;

Step S1310, judging whether a target tile with a matched target geographic position exists in a tile cache list in a tile cache module, wherein the tile cache list comprises a plurality of tiles, each tile in the plurality of tiles is used for caching area information associated with each geographic position in a target geographic area, the plurality of tiles comprise target tiles, and the target geographic area comprises the target geographic position;

step S1312, in the case that there is no target tile whose target geographic position matches in the tile cache list, sending a region data request to the downstream service interface;

step S1314, receiving the downstream service area information which is returned by the downstream service interface and is associated with the target geographic position, determining the downstream service area information as the area information which is associated with the target geographic position, and updating the tile list as a return result;

Step S1316, obtaining the area information of the target tile cache under the condition that the target tile with the matched target geographic position exists in the tile cache list;

step S1318, judging whether the region information meets the region output condition;

step S1320, determining the region information as the region information associated with the target geographic position as a return result when the region information meets the region output condition;

step S1322, when the area information does not meet the area output condition, sending an area data request to a downstream service interface;

step S1324, obtaining and judging a return result of the downstream service interface response;

Step S1326, receiving the downstream service area information which is returned by the downstream service interface and is associated with the target geographic position, determining the downstream service area information as the area information which is associated with the target geographic position, and updating the tile list as a return result when the return result indicates success;

Step S1328, in the case that the returned result indicates failure, searching a new target tile with the matched target geographic position from the tile cache list, wherein the new target tile is used for caching the area information associated with at least two geographic positions including the target geographic position; returning to step S1316, the above steps are repeatedly performed until the request result is returned.

As an alternative scheme, the method for acquiring the regional data is applied to the scene of recommending restaurant services for automobile users, the recommended services are accessed uniformly and the user data is issued, the current flow is larger along with the service growth, but the flow which can be borne by an interface which is required to be called by the recommended services to acquire the restaurants from a third party service provider is very small. The service is not available for a period of time and it is also difficult for third party service providers to extend the interface bearer capability.

In order to solve the problems, by using the tile caching scheme and setting multi-level caching, the access flow to the downstream interface is greatly reduced (99% of the flow is reduced), and the restaurant recommendation service can finally work normally (the total hit rate of the three-level tile caching reaches 99%). Through testing and parameter verification, the cache can be refreshed in time by fully utilizing the limited bearing capacity of the downstream interface, and the restaurant (within 500-1000 meters) near the current position of the user is recommended for the user.

For example, as shown in FIG. 14, the number of misses in the cache drops very quickly after the level 3 tile cache is used. Since the downstream service interface is not required to be accessed after the hit, the downstream service can be better protected. The tile cache has an expiration time and does not go to access the downstream service pull data until after the cache expires.

Further by way of example, as shown in fig. 15, the interface call data of the downstream service can be found to greatly reduce the traffic, and greatly improve the situation of high anomaly rate caused by insufficient interface bearing capacity.
