functionsClients, such as Web browsers, send requests to Web services and send them to the Flask application instance. The application instance needs to know what code to run for each URL request, so it creates a map of the URLs for the Python function.

methods is of type list, so you can specify multiple HTTP methods at the same time. In the following example, the URL rule/user supports both the Post method and the Get method: @app. Route ('/user ', methods=[' POST ', ' get ') def v_users (): if Request.method = = ' Get ': return ... # Back to user list if Request.method = = ' POST ' return ... #创建新用户 This feature makes flask very easy to develop back-end services for rest arch
