In the field of map data query, in order to ensure the security of map data query, corresponding authority control needs to be performed in the process of map data query, and in order to prevent all people from randomly accessing all map data, the authority control of users is mainly realized through a token mechanism in the related art. Specifically, the token is analyzed to obtain the corresponding user information, and the authority of the user can be controlled to a certain extent according to the user information. Although a certain degree of authority control can be realized through a token mechanism, in the actual use process, the related application has a certain difficulty in distinguishing different user roles according to the user information obtained by the token analysis, and the client also needs to maintain and update the token all the time to realize accurate authority control.
In view of this, the embodiments of the present application provide a three-dimensional map data query method and apparatus, which can effectively implement authority management and control of a user in a three-dimensional map data query process.
The following describes a three-dimensional map data query method according to an embodiment of the present application, as shown in fig. 1, fig. 1 is a flowchart of a three-dimensional map data query method according to an embodiment of the present application, where the method includes:
s101, a gateway service proxy receives a map service request sent by a client, wherein the map service request comprises target authority information of a query user, and the target authority information is used for determining a target query authority range of the query user.
The map data query method provided by the application is implemented on the gateway service proxy, and the gateway service proxy can run on a server capable of accessing the map service.
The client may obtain a map service request of the querying user, for example, an editable interface may be set on the client to edit the querying user to obtain a corresponding map service request, and in order to implement authority management and control in a map data querying process, the map service request includes target authority information of the querying user, where the target authority information may be used to determine a target querying authority range of the querying user, and the target querying authority range refers to a querying authority range corresponding to the querying user.
The method provided by the application is applied to the field of three-dimensional maps, so that the corresponding target query authority range is generally defined in a three-dimensional space.
After receiving the map service request sent by the client, the gateway service proxy can distribute the map service request to different authority processors according to the type of the map service request to realize corresponding data inquiry.
It should be noted that, the client may write the target authority information of the querying user into the map service request correspondingly, so as to ensure that the map service request includes the target authority information of the querying user. In addition, the client can write the address of the corresponding gateway service proxy into the map service request, so that the gateway service proxy can accurately receive the corresponding map service request.
In some embodiments, to achieve effective management of rights information of a user, the method further comprises;
the gateway service proxy obtains a plurality of authority information and a plurality of corresponding query authority ranges;
the gateway service broker stores the plurality of rights information and the plurality of query scope associations to a database.
In order to effectively manage and control the authority information of the user, a plurality of authority information and a plurality of corresponding query authority ranges can be acquired first, and the plurality of authority information and the plurality of corresponding query authority ranges are associated and stored in a database, so that in the related step, the corresponding target query authority range can be accurately determined according to the target authority information of the query user.
S102, if the map service request belongs to the map display category, the gateway service proxy forwards the map service request to the map service permission display processor so that the map service permission display processor determines a target three-dimensional display map corresponding to the target query permission range according to the map service request and returns the target three-dimensional display map to the client;
if the map service request belongs to the data query category, the gateway service proxy forwards the map service request to the query data service authority processor so that the query data service authority processor determines target three-dimensional query data corresponding to the target query authority range according to the map service request and returns the target three-dimensional query data to the client.
The gateway service proxy can distribute the map service request to the corresponding authority processor to realize corresponding operation according to the type of the map service request, and the main map service comprises map display and data inquiry, so the gateway service proxy can distribute the map service request to the display map service authority processor or the inquiry data service authority processor so as to carry out different processes on the map service request to respond to the map service request.
If the map service request belongs to a map display category, the map display category refers to that the request content of the map service request is to display an inquiry three-dimensional map to an inquiring user, the gateway service proxy can forward the map service request to a map service permission display processor so that the map service permission display processor can acquire the map service request and determine a target three-dimensional display map corresponding to a target inquiry permission range according to the map service request, wherein the target three-dimensional display map only retains map content corresponding to the target inquiry permission range corresponding to the inquiring user, for example, when the content of the map service request is to request to display a three-dimensional geographic information system data map service, the map service request is forwarded to the map service permission display processor, three-dimensional slice data in an S3MB format can be obtained, then three-dimensional slice data in the S3MB format is processed according to the target inquiry permission range, and only the target three-dimensional display map in the target inquiry permission range is retained; finally, the display map service permission processor can return the target three-dimensional display map to the client so as to inquire that the user can acquire the corresponding target display map at the client.
If the map service request belongs to a data query class, the data query class refers to that the request content of the map service request is that three-dimensional map data is displayed to a query user, the gateway service proxy can forward the map service request to the query data service authority processor so that the query data service authority processor can acquire the map service request, and determine target three-dimensional query data corresponding to a target query authority range according to the map service request, wherein the target three-dimensional query data only keeps map data corresponding to the target query authority range corresponding to the query user, and finally, the query data service authority processor can return the target three-dimensional query data to the client so that the query user can acquire the corresponding target three-dimensional query data at the client.
In some embodiments, the authority information includes an authority level for indicating a user-queriable administrative district level corresponding to the authority information and an authority identification for identifying a user-queriable administrative district name corresponding to the authority information.
In the actual query process of map data, users need to be subjected to authority control according to the space scope of administrative areas, for example, urban users can only access the data of the urban areas, regional users can only access the data of the areas, and street users can only access the data of the street areas. In the related art, the control of the authority of the user is realized by cutting the original map data in the process of releasing the map service by the server, specifically, the original map data can be cut according to the space ranges of different administrative areas to obtain a plurality of display maps with different display ranges, and when different users inquire the map data, the corresponding display map can be determined in the plurality of different display maps to display the user.
Although the authority control of the user can be realized by clipping the original map data, the original map data needs to be clipped for a plurality of times, which causes service redundancy for the server due to the fact that a large number of display maps are stored, and increases the production, update and maintenance costs of the server.
In this regard, the authority information set in the present application includes an authority level and an authority identifier, where the authority level is used to represent a user-queriable administrative area level corresponding to the authority information, where the authority level may include a street level, an area level, a city level, and the like, and the authority identifier is used to represent a user-queriable administrative area name corresponding to the authority information, where the authority identifier may include an a city, an a city B area C street, and the like.
By including the authority level and the authority identification in the authority information, the corresponding query authority range of the user can be accurately determined according to the authority information in the related steps, for example, the authority information of the user A is city level A city, and the corresponding query authority range can be determined as A city.
In some embodiments, the map service permission display processor determines a target three-dimensional display map corresponding to the target query permission range according to the map service request, including:
the map service permission display processor determines a corresponding target query permission range from the database according to the target permission level and the target permission identifier corresponding to the map service request, wherein the target query permission range comprises target query permission range coordinates;
the map service permission display processor determines target result range coordinates corresponding to the original result map data according to the map service request;
the display map service authority processor determines a display map corresponding to the intersection range coordinate of the target query authority range coordinate and the target result range coordinate as a target display map.
The display map service authority processor may parse target authority information included in the map service request, where the authority information includes a target authority level and a target authority identifier, and determine a corresponding target query authority range according to the target authority level and the target authority identifier, and in order to accurately identify the target query authority range, the target query authority range may include a target query authority range coordinate.
The display map service authority processor may determine a target result range coordinate corresponding to the original result map data according to the map service request, and specifically may acquire the original result map data corresponding to the map service request and the target result range coordinate corresponding to the original result map data, where the original result map data is corresponding initial map data determined only according to the map service request without considering authority information.
In order to acquire a target three-dimensional display map satisfying the target query authority range, the display map service authority processor may determine a three-dimensional display map corresponding to an intersection range coordinate of the target query authority range coordinate and the target result range coordinate as the target three-dimensional display map.
It should be noted that, if there is no intersection between the target query authority range coordinate and the target result range coordinate, a blank may be returned to the client, so that the query user knows that there is no authority.
In some embodiments, the query data service permission processor determines target three-dimensional query data corresponding to the target query permission range according to the map service request, including:
the query data service authority processor determines a corresponding target query authority range from the database according to the target authority level and the target authority identifier corresponding to the map service request;
the query data service authority processor determines a corresponding request query range according to the map service request;
the query data service processor takes the intersection range of the target query authority range and the request query range as a target query range;
the query data service processor determines query data corresponding to the target query range as target query data.
The query data service authority processor may parse target authority information included in the map service request, wherein the authority information includes a target authority level and a target authority identifier, and determine a corresponding target query authority range according to the target authority level and the target authority identifier, and in order to accurately identify the target query authority range, the target query authority range may include a target query authority range coordinate.
The query data service authority processor can determine a corresponding request query range according to the map service request, wherein the request query range refers to a query range which is determined on the basis of not considering target authority information.
In order to obtain the target query data satisfying the target authority information, the intersection range of the target query authority range and the request query range may be used as the target query range, and accordingly, the query data service processor may determine that the corresponding query data is the target query data according to the target query range.
It should be noted that, if there is no intersection between the target query authority range and the request query range, the target query authority range may be used as the target query range to determine the corresponding query data, so that the query user may receive relevant data in the authority range of the client, and the secondary query of the query user is reduced.
In summary, the embodiment of the application discloses a three-dimensional map data query method, which includes: the gateway service proxy receives a map service request sent by a client, wherein the map service request comprises target authority information of a query user, and the target authority information is used for determining a target query authority range of the query user; if the map service request belongs to the map display category, the gateway service proxy forwards the map service request to the map service permission display processor so that the map service permission display processor determines a target three-dimensional display map corresponding to the target query permission range according to the map service request and returns the target three-dimensional display map to the client; if the map service request belongs to the data query category, the gateway service proxy forwards the map service request to the query data service authority processor so that the query data service authority processor determines target three-dimensional query data corresponding to the target query authority range according to the map service request and returns the target three-dimensional query data to the client. By the method, authority management and control of the user can be effectively realized in the map data query process.
In addition, in the three-dimensional map data query method disclosed by the embodiment of the application, original map data is not cut and stored for multiple times, but target display maps or target query data meeting the target query permission range are determined to return according to the target permission information in the map service request, so that the redundancy of map data query can be effectively reduced, and the corresponding maintenance cost is reduced.
