如何在 drf APIView 中检索 URL 片段参数？

Question

I have created a callback view for instagram account connection in django by inheriting the APIView class.

After successful connection of instagram account facebook redirects me to the InstagramConnectCallbackView and includes the response data as a URL fragment.

url:

http://localhost:8000/v1/instagram-connect/callback/?#access_token=EAAN....&data_access_expiration_time=1650543346&expires_in=6254&state=eyd...

But I don't know how to read the URL fragments from the request into the get method.

callback view:

class InstagramConnectCallbackView(APIView):
    permission_classes = (permissions.AllowAny,)
    version = settings.FACEBOOK_GRAPH_API_VERSION

    def get(self, request, format=None):
        ....

I tried the following:

request.get_full_path() # returns `/v1/instagram-connect/callback/`
request.query_params()  # returns `{}`

Any help will be appreciated.

You can use query_params as

request.query_params.get('your_key_name')

If you want default then yot can use

self.request.query_params.get('your_key_name', None)

In your case you can get values like

access_token = self.request.query_params.get('access_token', None)
data_access_expiration_time = self.request.query_params.get('data_access_expiration_time', None)
expires_in = self.request.query_params.get('expires_in', None)

and so on ...
