Getting a parameter from an endpoint python flask

Question

I am trying to get 2 parameters from this URL http://127.0.0.1:5000/login/code=EULPK3PWJC1OLDY16UCLDKEZGUDLXUOYMP&state=342725139626065920

The parameters I am trying to get are code and state. The URL cannot be changed its an endpoint.

So far I came up with this code but it’s not working:

@app.route("/login/<string:code><int:state>", methods=['GET'])
def login(code, state):
    print(code, state)

and I am getting this error

The view function did not return a valid response.

When accessing the defined route, a return value is expected. You can return JSON, simple strings or HTML (render_template).

Example for that:

@app.route("/login/<string:code><int:state>", methods=['GET'])
def login(code, state):
    return {"Code": code, "State": state}

EDIT:

@app.route("/login/", methods=['GET'])
def login():
   code = request.args.get('code')
   state = request.args.get('state')
   return {"Code": code, "State": state}
