When accessing the defined route, a return value is expected.访问定义的路由时,需要返回值。 You can return JSON, simple strings or HTML (render_template).
您可以返回 JSON、简单字符串或 HTML (render_template)。
Example for that:示例:
@app.route("/login/<string:code><int:state>", methods=['GET'])
def login(code, state):
return {"Code": code, "State": state}
EDIT:编辑:
@app.route("/login/", methods=['GET'])
def login():
code = request.args.get('code')
state = request.args.get('state')
return {"Code": code, "State": state}
