if(state==1): return "fail" else: return "success" # @app.route('/staue', methods=['POST'])

It seems that there is a typo in your code. "staue" should be "state" in the route definition. Here is a corrected version:

@app.route('/state', methods=['POST'])
def check_state():
    if state == 1:
        return "fail"
    else:
        return "success"

Assuming that `state` is defined somewhere in your code, this route will respond to HTTP POST requests to the `/state` endpoint. If `state` is equal to 1, the function will return "fail". Otherwise, it will return "success".
