Detailed Description

Server generic API endpoint abstract base class.

See also

QgsServerOgcApi for an OGC API (aka WFS3) implementation.

An API must have a name and a (possibly empty) version and define a (possibly empty) root path (e.g. "/wfs3").

The server routing logic will check incoming request URLs by passing them to the API's accept(url) method, the default implementation performs a simple check for the presence of the API's root path string in the URL. This simple logic implies that APIs must be registered in reverse order from the most specific to the most generic: given two APIs with root paths '/wfs' and '/wfs3', '/wfs3' must be registered first or it will be shadowed by '/wfs'. APIs developers are encouraged to implement a more robust accept(url) logic by making sure that their APIs accept only URLs they can actually handle, if they do, the APIs registration order becomes irrelevant.

After the API has been registered to the server API registry:

class API(QgsServerApi):
 
  def name(self):
    return "Test API"
 
  def rootPath(self):
    return "/testapi"
 
  def executeRequest(self, request_context):
    request_context.response().write(b"\"Test API\"")
 
server = QgsServer()
api = API(server.serverInterface())
server.serverInterface().serviceRegistry().registerApi(api)

the incoming calls with an URL path starting with the API root path will be routed to the first matching API and executeRequest() method of the API will be invoked.
