Is there a way to pass an argument to a function defined within the dependencies argument of, for instance, app.get? If there isn't, what other options exist ? I can do the following to test a request, including examining the bearer token, before it reaches the endpoint handler: async def verify_token(Authorization: Annotated[str, Header()]): # decode token and do processing based on it @app.get("/read_items/", dependencies=[Depends(verify_token)]) async def read_items(): return [{"item": "Foo"}, {"item": "Bar"}] but what I really want to do is provide an argument to verify_token, like this: @app.get("/read_items/", dependencies=[Depends(verify_token("red")]) async def read_items(): return [{"item": "Foo"}, {"item": "Bar"}] in this scenario verify_token would accept a string as an argument and the value of that string would be easily seen by anyone inspecting the code. Of course this type of outcome could be produced by using a decorator: @verify_token_decorator("red") @app.get("/read_items/") async def read_items(): return [{"item": "Foo"}, {"item": "Bar"}] but decorators cannot inspect the contents of Request headers and so such a decorator would not be able to inspect the token. Is there a way to do the functional equivalent of passing a value into a function within the dependencies argument of an end point? Continue reading...
