Brief description of the drawings
Fig. 1 is a kind of schematic flow sheet of engine map implementation method that the embodiment of the present invention one is provided；
The engine map calling platform practical structures figure that Fig. 2 is applicable by the embodiment of the present invention one；
Fig. 3 is the structural representation that a kind of engine map that the embodiment of the present invention two is provided realizes device.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part rather than entire infrastructure related to the present invention is illustrate only in description, accompanying drawing.
Embodiment one
Accompanying drawing 1 is referred to, is a kind of schematic flow sheet of engine map implementation method that the embodiment of the present invention one is provided, should
Method is applied to the scene of map view application, and the method realizes device to perform that the device can be by software by engine map
And/or hardware is realized, is integrated in the inside of background server.The method specifically includes following steps：
S110, reception are called please.；
Specifically, background server receives the call request of foreground client, the call request goes to adjust for obtaining authority
With the secondary development API in background server, authority is obtained by background server equivalent to by call request
Secondary development API is transferred in foreground client, and corresponding map view application is completed with foreground client.The background service
Device is preferably Tomcat (tom cat) server.
S120, sent to client according to the call request and quote code, the reference code causes the client
Quote the tile map call method that secondary development API obtains search target.
Specifically, the code of quoting is the Javascript reference documents of secondary development API.Foreground client is being obtained
Before tile map call method, the reference qualification of map secondary development API is first obtained, so sending tune in foreground client
After request, background server can first give the qualification that foreground client permits quoting secondary development API, and the qualification passes through
Quote what code was realized, the code of quoting is the Javascript reference documents of secondary development API.
S130, the tile map call method of the reception from the client.
It should be noted that the tile map call method is to be determined according to the corresponding search characteristics of the search target
Corresponding tile map.
When it needs to be determined that during the search corresponding tile map of target, it is only necessary to match the search target is corresponding and search
Suo Tezheng, it is preferred that the search characteristics are corresponding to tile map imparting according to the geographical location information
The sequence number of the column in the sequence number and figure layer be expert in figure layer sequence number, figure layer, for example, can be that the search target is
Beijing, Pekinese geographical position and the layer for being included, row, column information are known, it is only necessary in corresponding tile map storehouse
Rigen transfers target tile map according to corresponding layer, row, column information.
S140, corresponding tile map is loaded according to the tile map call method.
It should be noted that obtain every tile as described in 130, in tile map storehouse being issued by Tomcat servers
Before, every specific search characteristics of tile map are all imparted according to geographical location information, by specific search characteristics shape
Into the tile map transferred of call method be stored in tile map storehouse.The storage rule in the tile map storehouse
For：To be first layered, then branch, row are divided afterwards.For example can be, Pekinese's tile map for the second layer the 5th row the 100th to
105th to 110 row of the 6th row of 112 row, the 98th to 115 row of the 6th row and third layer.
Optionally, can also include before S140：Tile map download request is sent to the webserver；Obtain described
The tile map that the webserver is transmitted according to the tile map download request；Or；
Map vector download request is sent to the webserver；The webserver is obtained according to vector ground
The map vector of figure download request transmission；It is tile map form by the Format adjusting of the map vector.
It should be noted that the tile map downloaded or the tile map as obtained by map vector is adjusted must all include
Cartographic information and geographical location information, for as every foundation of tile map special characteristic of imparting.
S150, the tile map is sent to the client so that the client splices the tile map.
Specifically, the tile map is sent into the secondary development API of client reference, secondary development API is being spelled
When connecing tile map, the special characteristic information in tile map is based on.For example can be that Pekinese's tile map is first spelled
Connect the second layer the 5th row the 100th to 112 row, splice again the 6th row the 98th to 115 row, then splice third layer the 6th row
The 105th to 110 row, the second last layer stacks splicing with third layer to be completed final map splicing and shows.
Above-mentioned engine map implementation method, can be realized by engine map calling platform, and it is by background server and preceding
Two parts of platform client are constituted.Concrete structure relation refers to Fig. 2, and Fig. 2 is drawn by the map that the embodiment of the present invention one is applicable
Hold up calling platform practical structures figure.
Background server includes map tile storehouse, secondary development API and the Tomcat server based on openlayers etc.
Functional module.
Foreground client includes business application system, can meet the daily industry of client by with background server real-time interaction
Business system needs to be embedded in the demand that map is browsed and shown business datum based on map, by mobile network and background service
Device docking contact.
It should be noted that two dotted line frames of foreground client be represent inframe content originally be not appear in foreground
Client, concrete reason is as follows：Foreground client after business application system obtains the reference authority of secondary development API,
Applied equivalent to the secondary development API in background server is transferred in foreground client, the parsing of follow-up tile map
Then displaying is also to be carried out in the secondary development API that foreground client is quoted with splicing.
In sum, the embodiment of the present invention one discloses a kind of engine map implementation method, by that will handle well in advance
Tile map is directly issued, and centre does not carry out the logical process of any complexity, disclosure satisfy that client's routine work system needs
Embedded map is browsed and is shown the demand of business datum based on map, moreover it is possible to ensure that system is merrily and lightheartedly compact, learning cost is low,
Easily deployment, easily problem, fast response time are investigated during error.
