Wherein, CORS (Cross-origin resource sharing, cross-domain resource sharing). The CORS needs to be supported by both the browser and the server to realize the cross-domain request.
The authorization Filter (authfilter) is used to authenticate the service path, and the service resource can be obtained only if the authority is allocated to the user in the management section page or the user successfully applies the authority of the resource.
The Log Filter (Log Filter) can realize link tracking, statistics service call, service monitoring and access amount statistics through Log record.
A Global Filter (Global Filter) is used to verify the service rights, adding necessary parameters to the service.
Wherein authenticating the service comprises:

And detecting the white list, realizing complete opening of authority for part of applications through white list configuration, and determining whether the application has the access authority or not through verifying the identity information of the access request terminal.
The cache filter (CACHE FILTER) adds a cache for service access, improves service performance after proxy, and can also improve service access speed through proxy.
The Route filter (Proxy Route GATE WAY FILTER) is used for Proxy routing, changes the Proxy address to the original address, makes a request, and passes the result after the request into the filter chain.
The service filter (Service Token Filter) checks whether the service needs to be provided with a token, judges whether the proxy service request is provided with a token request header, and if the proxy service request is provided with a request path which needs to be processed and spliced to the original service path, realizes the proxy of the GIS service which needs to be authenticated. Where token refers to a token in computing machine authentication, representing the right to perform certain operations.
A hierarchical filter (LAYER LEVEL FILTER) checks if the service requires hierarchical classification, which is to resolve hierarchical management, here by administrative division, cropping the data and returning the cropped picture to the front-end rendering page. For example, the IP address source of the access request is a city a, the corresponding access content is a map, and the map of the city a can be extracted from the whole map as a replaced map result.
The global response filter (Global Response Filter) is used for rewriting the request response data, and is used for reprocessing the original service returned page, and mainly modifying the url linked in the page, wherein the modification rule is shown as follows, for example, an arcgis service response content replacement rule is matched with an injection [ http:// ip: port/arcgis/] service path and replaced by [ http:// ip: port/dus// arcgis ], and the path of the page resource for jumping other resources can be replaced by a proxy through the replacement rule and then the proxy address is returned to the calling party.
And the method can further comprise a log filter (DusLog Filter) for recording service access logs, including cloud service platform log collection interception, and recording service application states and processes.
