Referring to fig. 1, fig. 1 is a schematic flowchart of a method for intelligent push service based on Redis according to an embodiment of the present invention; fig. 2 is a schematic view of an application scenario of a method for intelligent push service based on Redis according to an embodiment of the present invention. The method for intelligent push service based on Redis is applied to a server 10, in the method, after the server 10 receives a relevant instruction sent by a user terminal 20 to the server 10, the server 10 analyzes the instruction to obtain a target user matched with the user, and performs push service according to the target user, wherein the user terminal 20 is a mobile terminal with a positioning function, and the server 10 is a device with data transmission and reception functions with the user terminal 20.
As shown in fig. 1, the method includes steps S110 to S160.
S110, if a query request of a user for the current area is received, acquiring the query radius of the user for the current area according to the query request.
Specifically, the query request is that the user sends instruction information for querying a target user matched with the user in the current area to the server 10 in the user terminal 20, and after the user inputs data information of a query radius in the user terminal 20, the terminal can send instruction information for querying the target user matched with the user in the current area to the server according to the data information of the query radius, so that the query radius input by the user in the current area can be obtained through the query request.
And S120, performing Geohash coding on the longitude and latitude coordinates of the current position of the user according to a preset coding rule to obtain a Geohash value of the longitude and latitude coordinates.
Specifically, the encoding rule is rule information for the server to perform Geohash encoding according to the longitude and latitude coordinates of the current position of the user, wherein the Geohash encoding is an address encoding method, two-dimensional space longitude and latitude data can be encoded into a character string through the Geohash encoding, that is, the Geohash value of the longitude and latitude coordinates is represented through the character string.
In other inventive embodiments, as shown in fig. 3, step S120 includes sub-steps S121 and S122.
And S121, carrying out binary coding on the longitude and latitude coordinates according to a preset threshold value to obtain a character string of a binary sequence of the longitude and latitude coordinates.
Specifically, the threshold is a standard value set by subtracting the longitude in the latitude and longitude coordinate from the maximum longitude and the minimum longitude in the current longitude interval respectively after binary coding is performed for multiple times according to the latitude and longitude coordinate, or subtracting the latitude in the latitude and longitude coordinate from the maximum latitude and the minimum latitude in the current longitude interval respectively. In this embodiment, when any one of the first ratio or the second ratio does not exceed the threshold, binary coding is continuously performed on the longitude and latitude coordinates until any one of the first ratio or the second ratio exceeds the threshold, coding of the longitude and latitude coordinates is stopped, and then a character string after the longitude binary coding and a character string after the latitude binary coding in the longitude and latitude coordinates are combined to obtain a character string of a binary sequence of the longitude and latitude coordinates, wherein even digits of the character string of the binary sequence of the longitude and latitude coordinates include characters after the longitude binary coding, and odd digits include characters after the latitude binary coding.
And S122, coding the character string of the binary sequence of the longitude and latitude coordinates according to a Base32 coding table to obtain the Geohash value of the longitude and latitude coordinates.
Specifically, Base32 codes are used for coding binary data into visible character strings, and the coding rule is as follows: any given binary data is segmented into a group of 5 bits (bit), and each segmented group is encoded to obtain 1 visible character. In this embodiment, the character string of the binary sequence of the longitude and latitude coordinates is encoded through the Base32 encoding table, so that the Geohash value of the longitude and latitude coordinates can be obtained.
In other embodiments of the present invention, as shown in fig. 4, before the step S120, steps S120a and S120b are further included.
S120a, acquiring the network positioning and the GPS positioning of the user according to the inquiry request.
Specifically, the network positioning is used to acquire longitude and latitude coordinates of the current location of the user through transmission of network data, and the GPS positioning is used to acquire GPS data from the user terminal 20 of the user and send the GPS data to the server 10, so that the server 10 acquires the longitude and latitude coordinates of the current location of the user. In addition, the network location may be a location obtained by connecting the user terminal 20 of the user with the server 10 through WIFI, or a location obtained by connecting the user terminal 20 of the user with the server 10 through a base station through data transmission. When the user terminal 20 is connected with the server 10 through WIFI, the server 10 obtains longitude and latitude coordinates of the WIFI from a database according to the WIFI of the user terminal 20 of the user; when the user terminal is connected to the server 10 through the base station, the server 10 obtains the longitude and latitude coordinates of the base station from the database according to the base station of the user terminal 20 of the user, so as to indirectly obtain the longitude and latitude coordinates of the current position of the user, wherein the database is stored in the server 10 and is used for storing the WIFI and the position of the base station.
S120b, determining the longitude and latitude coordinates of the current position of the user according to the network positioning and the GPS positioning.
Specifically, the server judges for the first time according to the data information in the network positioning and the GPS positioning to obtain whether the network positioning is the same as the GPS positioning, if the first network positioning of the user terminal 20 of the user is the same as the first GPS positioning, the latitude and longitude coordinates of the current position of the user can be determined according to the network positioning or the GPS positioning, if the network positioning is different from the GPS positioning, the latitude and longitude coordinates of the current position of the user are determined according to the GPS positioning, and although the network positioning is fast after being connected to the internet, the external environment has strong interference to the network positioning, and at this time, the latitude and longitude coordinates of the current position of the user cannot be determined accurately through the network positioning.
In other inventive embodiments, as shown in fig. 5, step S120b includes sub-steps S120b1 and S120b 2.
And S120b1, judging whether the network positioning is consistent with the GPS positioning.
Specifically, the server 10 obtains the data information of the network positioning and the data information of the GPS positioning according to the query request sent from the user terminal 20 to the server 10, the server 10 analyzes the data information of the network positioning and the data information of the GPS positioning respectively to obtain the longitude and latitude coordinates corresponding to the network positioning and the longitude and latitude coordinates corresponding to the GPS positioning, wherein whether the network location and the GPS location are consistent is determined according to the error between the latitude and the longitude in the coordinates of the two, when the error between the longitude and latitude of the two coordinates does not exceed (0.05 ), the network location and the GPS location are determined to be consistent, when the error between the latitude and longitude in both coordinates exceeds (0.05 ), then the network location and the GPS location may be determined to be inconsistent.
S120b2, if the network positioning is not consistent with the GPS positioning, determining the longitude and latitude coordinates of the current position of the user according to the GPS positioning.
Specifically, the network positioning is fast relative to the GPS positioning, the user can perform the instant positioning at the user terminal 20 only by networking, the GPS positioning is slow in response, the time spent by the user at the user terminal 20 in the GPS positioning is longer than the time spent in the network positioning, and when the user at the user terminal 20 is a mobile communication device, the GPS positioning needs to consume a large amount of electric power of the mobile communication device, so that the longitude and latitude coordinates of the current position of the user are determined according to the network positioning.
And S130, calculating the grade of the Geohash grid of the current area according to the query radius.
Specifically, the query radius is radius information input by the user in the terminal based on the current position of the user, the level of the Geohash grid in the current region is the Geohash grid according with the lowest level of the current region, and the amount of later-stage search can be reduced through the Geohash grid. In this embodiment, the level of the Geohash grid of the current area is calculated by using the area with the current position of the user as the center of the circle. The Geohash grids are rectangular grids, and the Geohash grids of each level are composed of 4 Geohash grids which are higher than the Geohash grids by one level. The Geohash code of each Geohash grid is determined by the level of the Geohash grid, and in this embodiment, no Geohash grid with a higher level than the Geohash grid with the highest level is included in the Geohash grids with the highest level.
In other inventive embodiments, as shown in fig. 6, step S130 includes sub-steps S131 and S132.
S131, acquiring the first character string coded by Base32 from a preset dictionary table according to the query radius.
Specifically, the dictionary table is a character string which is prepared in advance and used for determining the query radius, and the character string is a character string encoded by Base 32. The number of the first character strings is equal to the number of character strings of the Geohash value of the Geohash grid of the current area. For example, the dictionary table may be represented in the specification as: when the query radius is 500 meters, querying the character string in the 400-600 meters range in the dictionary table as wx4g, and then taking the character string as the first character string, and then calculating the number of the character strings, so as to determine the level of the Geohash grid of the current region.
S132, determining the grade of the Geohash grid of the current area according to the number of the first character strings.
Specifically, the number of times of binary coding performed on the Geohash grid of the current region in the Geohash coding process can be determined according to the number of the first character strings, and the accuracy of the Geohash grid of the current region can be obtained according to the number of times of binary coding, so as to obtain the grade of the Geohash grid of the current region.
S140, acquiring the Geohash grid of the current area from the position set of the Redis Geo according to the grade of the Geohash grid of the current area.
Specifically, the location set of the Redis Geo is configured to store a set of all Geo-hash grids obtained by Geo-hash encoding of a location of a pre-region, where the set includes Geo-hash grids of all levels, and the Geo-hash grid of the current region can be obtained from the location set of the Redis Geo by the level of the Geo-hash grid of the current region. The Redis GEO is mainly used for storing the geographical position information and operating the stored information, and the function is newly added in the Redis 3.2 version. The Redis GEO operation instruction is as follows: geoadd is expressed as coordinates to add a geographic location; geopos represents coordinates for acquiring a geographic location; geodesist is expressed as calculating the distance between two locations; georadius represents that a geographical position set in a specified range is obtained according to longitude and latitude coordinates given by a user; georadiusbymmember represents that a geographical position set in a specified range is obtained according to a certain place stored in the position set; the Geohash is expressed as a Geohash value that returns one or more location objects.
In other inventive embodiments, as shown in fig. 7, step S140 includes sub-steps S141, S142, and S143.
S141, acquiring a plurality of GeoHash grids with the same level as the GeoHash grid of the current area from the position set of the Redis Geo according to the level of the GeoHash grid of the current area.
Specifically, when a preset area is coded, wherein the preset area contains the current area of the user, the area represented by the Geohash grid obtained by the Geohash coding is smaller and the level is higher as the number of times of binary coding is increased, and after the preset area is subjected to the Geohash coding, the Geohash grid of an inverted pyramid structure is formed, the accuracy grid of the top-level Geohash grid is the lowest, the level of the Geohash grid is also the lowest, and the accuracy and the level of the Geohash grid of the inverted pyramid structure are gradually and correspondingly increased from top to bottom, so that a plurality of Geohash grids with the same level as the Geohash grid of the current area are obtained from a position set of Redis Geo through the level of the Geohash grid of the current area.
And S142, acquiring second character strings with the number equal to that of the first character strings from the Geohash values of the longitude and latitude coordinates.
Specifically, the string of the Geohash value of the longitude and latitude coordinate represents the accurate location information of the user, so that the number of the string of the Geohash value of the longitude and latitude coordinate is certainly greater than the number of the first string, but since the number of the first string can determine the level of the Geohash grid of the current area, and the string of the Geohash value of the Geohash grid of the current area is positioned at the forefront of the string of the Geohash value of the longitude and latitude coordinate, and the number of the first string is equal to the number of the string of the Geohash value of the Geohash grid of the current area, the Geohash grid of the current area can be obtained from a plurality of Geohash grids which are the same as the level of the Geohash grid of the current area through the second string. The second character string is identification information of the Geohash grids of the current area, and the Geohash grids of the current area can be obtained from a plurality of Geohash grids with the same level as the Geohash grids of the current area through the second character string. In this embodiment, the current location of the user in the Geohash grid of the current region is a positive center of the Geohash grid of the current region.
S143, obtaining the Geohash grids of the current area from the Geohash grids with the same level as the Geohash grids of the current area according to the second character string.
S150, acquiring a target user matched with the user from the Geohash grid of the current area according to the Geohash value of the longitude and latitude coordinates.
Specifically, after the current area is determined, a plurality of target users having the same user attribute may be obtained from the Geohash grid of the current area according to the attribute information of the user, that is, a plurality of target users exist in the Geohash grid of the current area, but the distance between each target user and the user is different, so that the target user closest to the user needs to be screened out from the target users, and the target user closest to the user performs an intelligent push service on the user, so that the precision and the success rate of push are improved, and the quality of the push service is improved.
In other inventive embodiments, as shown in FIG. 8, step S150 includes sub-steps S151 and S152.
And S151, processing the Geohash grid of the current area according to the number of the character strings of the Geohash values of the longitude and latitude coordinates to obtain the Geohash grid according with the longitude and latitude coordinates.
Specifically, after the Geohash grid of the current area is obtained, because the Geohash grid of the current area is a Geohash grid of an inverted pyramid structure, and the accuracy of the bottom layer of the Geohash grid of the current area far exceeds the accuracy of the longitude and latitude coordinates, the partial Geohash grid which does not conform to the accuracy of the longitude and latitude coordinates is removed by the number of character strings of the Geohash value of the longitude and latitude coordinates, and then the Geohash grid conforming to the longitude and latitude coordinates is obtained.
S152, acquiring the target user from the Geohash grid according with the longitude and latitude coordinates according to a recursive algorithm.
Specifically, the recursive algorithm searches from four high-level Geohash grids of a topmost Geohash grid of the Geohash grids conforming to the longitude and latitude coordinates, and if a target user matched with the user does not exist in the four high-level Geohash grids, that is, a position code of the target user does not exist in the current Geohash grid, searches from four lower-level Geohash grids corresponding to the four high-level Geohash grids, and sequentially searches from top to bottom until a target user closest to the user is found.
And S160, pushing service information matched with the query request to the user according to the target user.
Specifically, after a target user matched with the user is determined, information associated with the user in the target user is pushed to the user through a user terminal. For example, the user wants to purchase a financial product, the target user queried through the query request also purchases the financial product and obtains a profit when purchasing the financial product, and the server can push the profit information obtained by the target user to the user after determining the target user, that is, the profit information is service information matched with the query request.
In the method for intelligent push service based on Redis provided by the embodiment of the invention, if a query request of a user for a current area is received, a query radius of the user for the current area is obtained according to the query request; performing Geohash coding on the longitude and latitude coordinates of the current position of the user according to a preset coding rule to obtain a Geohash value of the longitude and latitude coordinates; calculating the grade of the Geohash grid of the current area according to the query radius; acquiring the Geohash grid of the current region from a position set of Redis Geo according to the grade of the Geohash grid of the current region; acquiring a target user matched with the user from the Geohash grid of the current area according to the Geohash value of the longitude and latitude coordinates; and pushing service information matched with the query request to the user according to the target user. By the method, the target user matched with the user can be obtained, and the target user can be used for carrying out intelligent pushing service on the user, so that the accuracy of the pushing service is improved, and the service quality is improved.
