Description

Information caching method, device, equipment and medium

Technical Field

The embodiment of the invention relates to the technical field of computers, in particular to an information caching method, device, equipment and medium.

Background

With the rapid development of networks, querying items of interest through networks has been widely used. How to ensure the stability of a system on the basis of being capable of rapidly and accurately responding to an access request of a user to an article has become a technical problem to be solved.

In the prior art, in order to relieve the pressure of the system, the data returned by the request is stored in the cache for a period of time, so that the pressure on the database is relieved, and the performance of the system is improved. FIG. 1 is a schematic diagram of a prior art cache architecture of a background system. As shown in FIG. 1, the background system receives the request 110, queries the cache 120 first, and queries the database 130 when there is no corresponding information in the cache 120. Fig. 2 is a flowchart of a prior art method for responding to an access request initiated by a user, as shown in fig. 2, when an access request is detected, S210 is executed, a response is started, S220 is executed to query whether there is corresponding data in a cache, if there is no response data corresponding to the access request, S230 is executed to query corresponding response data from a database, S240 is executed, the response data is written back into the cache, S250 is executed, the response data is returned to a terminal that initiates the access request, if there is response data corresponding to the access request in the cache, the response data is directly returned to the terminal that initiates the access request, and S260 is executed until the response is completed.

In the process of implementing the present invention, the inventor finds that at least the following technical problems exist in the prior art: with the update of the application program, the user can access the article through different channels, and the article information corresponding to different channels may be different. If the access requests from different channels are cached by the existing caching method, a specific piece of data is cached. When a large number of access requests are received, the system caches the article information corresponding to each request, so that the server cache is occupied easily, and the system is not available. If only the fixed information of the article is stored in the cache, but article information which is different due to different channel sources is not stored, when the access requests sent by different channels are received, the article information needs to be acquired from the database and the calling upstream interface, and the request delay is easy to be caused.

Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Example 1

Fig. 3 is a flowchart of an information caching method according to an embodiment of the invention. The present embodiment is applicable to a case when information of an access object is cached. The method may be performed by an information caching apparatus, which may be implemented in software and/or hardware, e.g. the information caching apparatus may be arranged in a computer device. As shown in fig. 3, the method includes:

S310, receiving an information access request from an access channel, wherein the information access request comprises a channel identifier of the access channel and an object identifier of an access object.

In this embodiment, the information access request may be a request triggered by the user through the terminal for accessing the access object. Optionally, the user may select an object of interest on the terminal, perform a clicking operation, trigger an information access event, and the terminal detects the information access event triggered by the user, and generates and sends a corresponding information access request. In the present embodiment, the information access request includes a channel identification of the access channel and an object identification of the access object. It is understood that the access object may be a physical object or a virtual object.

When a user wishes to view detailed information of an article a displayed on a terminal screen, the information access event can be triggered by clicking an area where the article a is located on the terminal, the terminal detects the information access event triggered by the user, determines an object identifier "1" of an access object according to the content of the displayed page on the terminal screen and the detected touch screen position, determines a channel identifier "2" of an access channel according to a channel of the information access event triggered by the user, generates an information access request containing the object identifier and the channel identifier, sends the information access request to a background server, and then sends the information access request to an information caching device.

In this embodiment, the user may access the access object through different channels. The user accessing the same access object through different channels can be understood as an information access event triggered by clicking a jump link of the same access object on different pages. For example, when the same item a is provided with jump links on both the page of the application program B and the page of the application program C, the user 1 accesses the item a through the jump links provided on the page of the application program a, and the user 2 accesses the item a through the jump links provided on the page of the application program B, so that the access of the user 1 and the user 2 to the item a is the access to the item a through different channels.

S320, generating a query identifier of the access object according to the channel identifier and the object identifier, and matching the query identifier with at least one storage identifier in the cache.

In this embodiment, in order to query the information of the access object under a certain channel, a query identifier of the access object needs to be formed according to the channel identifier of the access channel of the access object and the object identifier of the access object.

Optionally, the object identifier and the channel identifier may be used together as a query identifier of the access object, or the object identifier and the channel identifier may be processed (e.g. in a manner of operation, encryption, etc.) to obtain the query identifier of the access object.

In one embodiment of the present invention, the generating the query identifier of the access object according to the channel identifier and the object identifier includes: and splicing the object identifier and the channel identifier end to form the query identifier of the access object.

Optionally, the object identifier and the channel identifier may be spliced first to form a query identifier of the access object. The first splicing mode is simple to operate, and can ensure that the same query identifier can point to a unique channel and a unique access object, so that the accuracy of information is ensured, and information errors of the access object caused by inaccuracy of the query identifier are avoided. For example, if the object identifier of the access object is "1" and the channel identifier is "2", the query identifier obtained by first splicing the object identifier and the channel identifier is "12".

In this embodiment, after determining the information corresponding to the information access request, the query identifier corresponding to the information access request and the information corresponding to the query identifier are stored in the cache, so that when the access request for accessing the same access object through the same channel is received again, the corresponding information record is queried from the cache. Therefore, when receiving the information access request, the query identifier of the access object is matched with the storage identifier stored in the cache, so as to query whether the information record corresponding to the query identifier exists in the cache.

S330, if the storage identification matched with the query identification does not exist in the cache, requesting to acquire the channel information record corresponding to the query identification.

In this embodiment, if the storage identifier matched with the storage identifier does not exist in the cache, a request needs to be sent to the information server, and the information server obtains the channel information record corresponding to the query identifier. The channel information record is an information record of the access object under the channel corresponding to the channel identifier.

It will be appreciated that the information presented when the access object is accessed through different channels may be different for each access object, but that the access object does not have its specific channel information under each channel. Illustratively, there are channel 1, channel 2, channel 3, and item a may have corresponding channel information in each of channel 1, channel 2, channel 3; or item a may have corresponding channel information in channel 1, channel 2, but not in channel 3.

Accordingly, in the information server, channel information records of the access object under each channel are stored. Considering that the number of channels is large and the channels are not fixed (if a certain channel is currently available and becomes unavailable after a period of time), optionally, for each access object, only the channel identifier with specific channel information, the object identifier and the corresponding relation between the information and the corresponding relation between the object identifier and the information are stored in the information server.

In one embodiment of the present invention, the information caching device may send the object identifier and the channel identifier to the information server, and the information server determines the query identifier of the access object according to the object identifier and the channel identifier, obtains the channel information record corresponding to the query identifier, and sends the channel information record to the information caching device.

If the channel information record matched with the query identifier cannot be matched in the information server, judging that the access object corresponding to the object identifier does not have specific channel information under the channel corresponding to the channel identifier, returning the null value to the information caching device, and sending the object identifier and the fixed information record corresponding to the object identifier to the information caching device.

And if the channel information record matched with the query identifier can be matched in the information server, sending the matched channel information record to the information caching device.

And S340, if the channel information record is a null value, storing the query identifier and the null value in a cache in a corresponding manner.

In this embodiment, if the channel information record returned by the information server is empty, it is determined that the access object corresponding to the object identifier does not have specific channel information in the channel corresponding to the channel identifier, and the query identifier and the empty value are stored in the cache in correspondence.

For example, if the object identifier of the access object is "1", the channel identifier is "2", the query identifier is "12", and the channel information record of the access object under the channel corresponding to the channel identifier 2 obtained by the information server is NULL, the query identifier "12" and a NULL value (NULL) are stored in the cache in correspondence.

Compared with the prior art, when channel information records corresponding to query identifiers do not exist, the method for storing the query identifiers and the fixed information records in the cache makes null marks for invalid channel data, and the query identifiers and the null are correspondingly stored in the cache, so that when continuous access requests of high-frequency words sent through different channels are received, the memory occupied by response information corresponding to a large number of access requests in the cache can be greatly reduced.

Example two

Fig. 4 is a flowchart of an information caching method according to a second embodiment of the present invention. The present embodiment is further optimized on the basis of the above embodiment. As shown in fig. 4, the method includes:

S410, receiving an information access request from an access channel, wherein the information access request comprises a channel identifier of the access channel and an object identifier of an access object.

S420, generating a query identifier of the access object according to the channel identifier and the object identifier, and matching the query identifier with at least one storage identifier in the cache.

S430, if the storage identification matched with the query identification does not exist in the cache, requesting to acquire the channel information record corresponding to the query identification.

S440, if the channel information record is null, the query identifier and the null are stored in the cache, the fixed information record corresponding to the object identifier is obtained, and the object identifier and the fixed information record are stored in the cache.

In this embodiment, the fixed information record is an information record of the access object under a non-channel. If the channel information record corresponding to the query identifier of the access object is null, the fixed information record of the access object is required to be acquired, and the object identifier of the access object and the fixed information record of the access object are correspondingly stored in the cache, so that when the same access request is received again, the fixed information record of the access object can be acquired from the cache, and the fixed information record of the access object can be acquired through the information server when the query identifier is invalid and the information record corresponding to the query identifier is empty in the cache is avoided. The method has the advantages that the effective data cache can only cache one part by setting the null value mark, and meanwhile, when the transparent incoming parameter is invalid (the access object does not have the corresponding channel information record), one part of normal data cache can be returned, so that the usability of the system is ensured, and the user experience is improved.

For example, if the object identifier of the access object is "1", the channel identifier is "2", the query identifier is "12", the channel information record of the access object under the channel corresponding to the channel identifier 2 obtained by the information server is empty, and the fixed information record "F" of the access object obtained by the information server is obtained, then the object identifier "1" and the fixed information record "F" are stored in the cache on the basis that the query identifier "12" and the empty value (NULL) are stored in the cache correspondingly.

S450, taking the fixed information record as a target information record corresponding to the query identifier, and returning the target information record to the client.

In this embodiment, if the matched target information record cannot be queried in the cache according to the query identifier of the access object, and the channel information record of the access object queried by the information server under the channel corresponding to the channel identifier is empty, the fixed information record of the access object is used as the target information record corresponding to the query identifier, and the target information record is returned to the client.

For example, if the channel information record of the access object under the channel corresponding to the channel identifier 2 is empty in the information access request initiated by the client through the channel 2, the information server obtains the fixed information record "F" of the access object, and then sends the information record "F" to the client.

In the present embodiment, the execution order of S440 and S450 is not limited. The operation of storing the query identifier and the null value, and the object identifier and the fixed information record in the cache in S440 may be performed first, and then the operation of sending the fixed information record as the target information record to the client in S450 may be performed; the operation of sending the fixed information record to the client as the target information record in S450 may be performed first, and then the operation of storing the query identifier and the null value, and the object identifier and the fixed information record in the cache in S440 may be performed.

According to the technical scheme provided by the embodiment of the invention, if the channel information record is null, the fixed information record and the access identifier are correspondingly stored in the cache, the fixed information record is used as the target information record corresponding to the query identifier, the target information record is returned to the client, and when the channel information record is null, the fixed information record of the access object is returned to the client, so that when the query identifier is invalid, a part of normal channel-free data can be responded, and the usability of the system is ensured.

On the basis of the scheme, the device also comprises;

If the channel information record acquired through the information server is not empty, the query identifier and the channel information record are correspondingly stored in a cache, the channel information record is used as a target information record corresponding to the query identifier, and the target information record is returned to the client.

In one implementation of this embodiment, if the matching target information record cannot be queried in the cache according to the query identifier of the access object, but the channel information record of the access object queried by the information server under the channel corresponding to the channel identifier is not empty, it is indicated that the access object has specific channel information under the channel corresponding to the channel identifier, the channel information record is used as the target information record of the access object, and the target information record is returned to the client as the response information.

For example, if the channel information record of the access object under the channel corresponding to the channel identifier 1 is "H" and is not null in the information access request initiated by the client through the channel 1, the information record "H" is returned to the client as the response information of the information access request.

Example III

Fig. 5 is a flowchart of an information caching method according to a third embodiment of the present invention. The present embodiment is further optimized on the basis of the above embodiment. As shown in fig. 5, the method includes:

S510, receiving an information access request from an access channel, wherein the information access request comprises a channel identifier of the access channel and an object identifier of an access object.

S520, generating a query identifier of the access object according to the channel identifier and the object identifier, and matching the query identifier with at least one storage identifier in the cache.

And S530, if the storage identifier matched with the query identifier exists in the cache, acquiring the channel information record corresponding to the storage identifier, determining the target information record corresponding to the query identifier according to the channel information record, and returning the target information record to the client.

In this embodiment, when a storage identifier matching the query identifier exists in the cache, the response process of the information access request is specified. Optionally, if the storage identifier matched with the query identifier exists in the cache, the target information record of the access object can be directly obtained in the cache without being obtained through an information server.

Optionally, the query identifier is matched with the storage identifier in the cache, and the channel information record corresponding to the storage identifier matched with the query identifier is obtained. It can be understood that, by the information caching method provided by the embodiment of the invention, when the article corresponding to the query identifier does not have specific channel information under the channel corresponding to the channel identifier, the corresponding channel information stored in the cache is recorded as a null value. Therefore, it is necessary to determine the target information record corresponding to the query identifier according to whether the channel information record corresponding to the storage identifier is null.

In one embodiment of the present invention, the determining, according to the channel information record, a target information record corresponding to the query identifier includes:

If the channel information record is null, acquiring a fixed information record corresponding to the object identifier in the cache, and taking the fixed information record as the target information record;

And if the channel information record is not null, the channel information record is used as the target information record.

In this embodiment, if the channel information record is empty, acquiring a fixed information record of the access object corresponding to the object identifier stored in the cache according to the object identifier of the access object, and taking the fixed information record as a target information record corresponding to the query identifier; if the channel information record is not empty, the channel information record is used as a target information record corresponding to the query identifier, so that effective data can be obtained under the condition that the query identifier is invalid or effective.

For example, if the query identifier of the access object is "12", the channel information record corresponding to the storage identifier "12" in the cache is "NULL", and the fixed information record "F" corresponding to the object identifier "1" in the cache is obtained as the target information record corresponding to the query identifier "12". If the channel information record corresponding to the storage identifier "12" in the cache is "G" and is not empty, the channel information record "G" is used as the target information record corresponding to the query identifier "12".

According to the technical scheme provided by the embodiment of the invention, when the storage identifier matched with the query identifier exists in the cache on the basis of the embodiment, the response process of the information access request is embodied. And if the storage identifier matched with the query identifier exists in the cache, determining a target information record corresponding to the query identifier according to the channel information record corresponding to the storage identifier, so that effective data can be obtained under the condition that the query identifier is invalid or effective, and the usability of the system is ensured.

Example IV

Fig. 6 is a flowchart of an information caching method according to a fourth embodiment of the present invention. The embodiment provides a preferred embodiment based on the above embodiment, and the embodiment takes channel price as an example to embody the information caching method. In this embodiment, the channel price is a specific price when the same access object accesses through different channels, and the no-channel price is a fixed price when the access object accesses through non-channels. As shown in fig. 6, the method includes:

s601, starting.

S602, whether the channel KEY has a cache or not.

In this embodiment, when a certain channel source requests access to a certain article of the system, a specific channel KEY is assembled according to a channel identifier (channel source identifier) and an object identifier of the article, so that each channel source can be distinguished, and then whether the newly generated channel KEY exists in a cache is determined.

If the channel KEY exists in the cache, S603 is executed; if the channel KEY does not exist in the cache, S605 is executed.

S603, whether the flag is a null KEY.

If the channel KEY exists in the cache, judging whether the channel KEY is a marked null KEY or not. Alternatively, whether the channel KEY is a marked null KEY may be determined by determining whether the data stored in correspondence with the channel KEY is a null value. If the data stored in the channel KEY is null, it is determined that the channel KEY is marked with null KEY, and S604 is executed, and if the data stored in the channel KEY is not null, it is determined that the channel KEY is not marked with null KEY, and S610 is executed.

S604, taking data in the non-channel KEY.

If the information stored corresponding to the channel KEY is a null value mark, acquiring data corresponding to the non-channel KEY according to the non-channel KEY (object identification) and returning.

S605, query the database and upstream interface.

If the channel KEY does not exist in the cache, the fact that the channel has no request access to the article in the last period of time is proved, and the database is required to be accessed, an upstream interface is queried, and the cache is updated.

S606, whether channel prices exist.

And judging whether the article has channel price under the channel or not by accessing the database and the return data of the upstream interface. If the item has a channel price under the channel, S607 is performed, and if the item does not have a channel price under the channel, S608 is performed.

S607, after the result is assembled, storing the result in a cache corresponding to the channel KEY.

If the article has a channel price under the channel, the channel KEY and the channel price corresponding to the channel KEY are assembled and then written into the cache corresponding to the channel KEY, and then S410 is executed to return data. When the same channel source requests the article in a short time, the stored data can be directly returned.

S608, channel KEY null value marking.

S609, storing a piece of data in the non-channel KEY.

If the article does not have the channel price in the channel, writing a null mark in the buffer corresponding to the channel KEY, storing a piece of data without the channel price in the buffer corresponding to the non-channel KEY, executing S610, and returning the data. When the same channel source requests the article in a short time, firstly checking the data in the channel KEY corresponding to the article, and after the empty value mark is found, jumping to the data corresponding to the non-channel KEY to take the data without channel price and returning the data.

S610, returning data.

And returning the acquired data to the terminal corresponding to the article access request.

S611, ending.

According to the technical scheme, when the channel price cannot be obtained, the empty value mark is stored in the cache of the channel KEY, so that the channel is invalid for the current article, only a small memory space is occupied, and the possibility that the memory is occupied is avoided. In addition, a part of non-channel data is stored in the non-channel KEY, so that when the non-channel data is not stored, the non-channel data of the article cannot be cached when a non-channel source request is received, and a database and an upstream interface can be accessed for each request, and huge hidden danger is brought to a system. The embodiment of the invention solves the hidden buffering trouble caused by transparent transmission parameters, and aims at entering the parameters of different channels, not only simply buffering data, but also making different buffering strategies according to the effectiveness of the channels on the objects, thereby preventing the memory from being filled with malicious access data, ensuring the availability of the system, and simultaneously ensuring the stability of database access and upstream interface call quantity.
