Flask Web开发通过app.route传递多个变量

Question

what im trying to do today is to pass multiple variables thru links to flask or just additional symbols followed by url i have tried this

@app.route('/?action='+'<cmd>')

or

@app.route('/?<cmd>')

both give me a 404 error

but when i remove the "?" symbol it works fine. Any ideas?

If you want to get query string parameter values the best way is to do this in your @app.route function. For example, getting the action query string parameter:

@app.route('/')
def index():
    action = request.args.get('action')
