At step 101, a first longitude and latitude of a current location of a user is obtained.
Specifically, when a user enters/does not enter a specific range, a specific software/applet is opened, and the system calls a map software API to acquire the longitude and latitude of the current position of the user. The electronic map service provider can select a Baidu map, a Google map or a Gade map, and the like, and can also select an own address library for extraction. The extracted coordinate data is resolved into longitude and latitude coordinate data through an electronic map service provider or a self-owned address base, and the processing is more convenient.

and checking whether the acquired first longitude latitude is legal or not, if so, judging whether the first longitude latitude exists in the defined electronic geo-fence, and if not, returning null data.
Specifically, the acquired first longitude and latitude is called to the back-end service interface, and the back-end program judges and checks according to whether the longitude and latitude are legal (namely, whether the first longitude and latitude acquired by the service end is not empty) and whether the acquired longitude and latitude (namely, the first longitude and latitude) exist in the defined electronic geo-fence.
In some embodiments, the method of determining whether the first longitude and latitude exists within the demarcated electronic geofence comprises:
determining whether the designated electronic geofence exists;
if the electronic geofence exists, connecting outermost points of coordinates (namely second longitude and latitude coordinates) corresponding to the longitude and latitude of the electronic geofence by using a convex hull algorithm to form a convex polygon;
and judging whether the acquired first longitude latitude is within the convex polygon range, if so, determining that the first longitude latitude exists in the defined electronic geo-fence, and if not, determining that the first longitude latitude does not exist in the defined electronic geo-fence.
Specifically, whether a first longitude and latitude is processed in a Path2D type of a JDK internal toolkit logically used in the defined electronic geo-fence is judged, and the principle of the Path2D bottom layer is that points on the outermost layer of a second longitude and latitude coordinate of the defined electronic geo-fence are connected to form a convex polygon by using a convex hull algorithm; and judging whether the acquired first longitude latitude is within the range or not, and calling Path2D.
At step 103, if the first longitude latitude exists within the electronic geofence as defined, a corresponding unique identification of the campus is obtained based on the first longitude latitude.
In step 104, it is determined whether the acquired unique identifier of the campus is single, if so, the corresponding campus service recommendation information is displayed to the user according to the unique identifier of the campus, and if not, null data is returned.
In particular, there may be multiple designated campus electronic geofences. Storing the unique park identification returned to the currently processed electronic geo-fence into an array; polling and judging the set park electronic geofences, judging whether the first longitude and latitude exists in the electronic geofences of each defined park, judging whether the first longitude and latitude exists, and storing the result (the corresponding unique park identification) into an array; and after the polling is finished, judging whether the number of the unique identifications of the parks in the array is single, successfully positioning the single number of the unique identifications, inquiring specific service recommendation information of the parks according to the obtained unique identification of the single park, returning to a calling end for carrying out corresponding information display, failing to position the plurality of unique identifications or the array is empty, and returning empty data. The campus service recommendation information may be recruitment information, campus introduction information, recruiter information, advertisement provided for goods or services, etc. The presentation may be performed via a display screen of the electronic device.
In some embodiments, the method for presenting the corresponding campus service recommendation information to the user according to the unique campus identifier includes:
storing the demarcated electronic geo-fence, the corresponding unique campus identification and the campus service recommendation information into a database;
and searching the corresponding park service recommendation information in the database and displaying the park service recommendation information based on the acquired park unique identifier.
In some embodiments, after obtaining the corresponding unique campus identification based on the first longitude latitude, the method further includes:
acquiring a partition of a park where the user is currently located based on the first longitude and latitude, and further acquiring a corresponding partition unique identifier;
and judging whether the obtained unique partition identifier is single, if so, displaying corresponding partition service recommendation information to the user according to the unique partition identifier.
Specifically, there may be multiple partitions in a campus, and each partition corresponds to different service recommendation information, such as commodity service information and recruitment information of different merchants. Different partitions can be divided according to the actual geographic positions of different merchants in the park, and then different partitions are divided in the electronic map. Different from the unique park identifier representing the entire park, the unique different partition identifiers represent different partitions in the park, and the different partitions may be areas where different merchants are located. The method for determining whether the first longitude latitude exists in the defined partition refers to the aforementioned method for determining whether the first longitude latitude exists in the defined electronic geo-fence, and is not repeated herein.
By the method, the geo-fence positioning function is used for positioning the park where the user is located in a specific range, so that the user can use the function based on the data of the positioned park. Therefore, accurate positioning and accurate service recommendation of users located in different parks are achieved.
