Method and apparatus for obtaining data based on location information

A server for obtaining data based on location information, the server comprising:

• at least one memory configured to store computer program code;
• a receiver configured to receive, from a remote querying user terminal, a query request that is used to obtain object information, the query request carrying location information of the remote querying user terminal;
• at least one processor configured to access the at least one memory and operate as instructed by the computer program code, the computer program code comprising:
• first determining code configured to determine a frequency of user terminals executing a query operation in an area range in which the location information of the remote querying user terminal is located;
• first query code configured to query, in response to a cache area being not empty, the cache area for hotspot data in the area range, the hotspot data being information of an object comprised in the area range, and the hotspot data being cached in response to the frequency of the user terminals executing the query operation in the area range exceeding a predetermined threshold number;
• second query code configured to query the cache area for the area range in which the location information of the remote querying user terminal is located, the cache area caching at least a preset area range, and for the hotspot data in the area range;
• first reading code configured to read, in response to the querying the cache area being successful, the hotspot data in the area range, from the cache area;
• first obtaining code configured to, in response to the querying the cache area failing, obtain, from a third party server, the hotspot data in the area range and cache the area range and the hotspot data in the area range, into the cache area;
• first conversion code configured to convert two-dimensional longitude and latitude data that is used to denote the area range into a one-dimensional first character string code;
• first cache code configured to associate the first character string code and the hotspot data that is obtained, and cache the first character string code associated with the hotspot data that is obtained, into the cache area;
• second conversion code configured to convert longitude and latitude data in the location information of the remote querying user terminal, into a second character string code;
• third query code configured to query whether the cache area stores the first character string code that is same as the second character string code;
• second determining code configured to, in response to a determination that the first character sting code is the same as the second character string code, store the area range in the cache and determine that the area range is successfully found through query;
• and
• third determining code configured to determine, in response to a determination that the first character sting code is different than the second character string code, that the area range is unsuccessfully queried;
• and
• a transmitter configured to send, to the remote querying user terminal, the hotspot data in the area range.

A non-transitory computer-readable storage medium storing program code comprising instructions for causing a server to:

• receive, from a remote querying user terminal, a first query request that is used to obtain object information, the first query request carrying location information of the remote querying user terminal;
• determine a frequency of user terminals executing a query operation in an area range in which the location information of the remote querying user terminal is located
• query, in response to a cache area being not empty, the cache area for hotspot data in the area range, the hotspot data being information of an object comprised in the area range, and the hotspot data being cached in response to the frequency of the user terminals executing the query operation in the area range exceeding a predetermined threshold number;
• query the cache area for the area range in which the location information of the remote querying user terminal is located, the cache area caching at least a preset area range, and for the hotspot data in the area range;
• read, in response to the querying the cache area being successful, the hotspot data in the area range, from the cache area;
• in response to the querying the cache area failing, obtain, from a third party server, the hotspot data in the area range, and caching the area range and the hotspot data in the area range, into the cache area;
• convert two-dimensional longitude and latitude data that is used to denote the area range into a one-dimensional first character string code;
• associate the first character string code and the hotspot data that is obtained;
• cache the first character string code associated with the hotspot data that is obtained, into the cache area;
• convert longitude and latitude data in the location information of the remote querying user terminal, into a second character string code;
• query whether the cache area stores the first character string code that is same as the second character string code;
• in response to a determination that the first character sting code is the same as the second character string code, store the area range in the cache and determine that the area range is successfully found through query;
• and
• determine, in response to a determination that the first character sting code is different than the second character string code, that the area range is unsuccessfully queried;
• and
• send, to the remote querying user terminal, the hotspot data in the area range.
