flask前后交互，python？

if __name__ == '__main__':
    with open('commandcode.json') as commandcode:
        head_baowen = json.load(commandcode)
        running_head_baowen = head_baowen["total_baowen_head"]["running_state_data"]
        operation_head_baowen = head_baowen["total_baowen_head"]["operation_move"]
        data_baowen = head_baowen["total_baowen_head"]["data_baowen"]
        addr = (head_baowen['addr']['addr1'][0], head_baowen['addr']['addr1'][1])

    app.run(debug=True, host='127.0.0.1', port=8000)


@app.route("/suspend", methods=["POST"])
def web_command_suspend():
    b = operation_type('2', message_add(data_baowen))
    send_move_command(operation_head_baowen, b, addr)

    return {"msg": "suspend"}

 

 

 

错误：

send_move_command(）只有3个参数位置

错误提示是缺少addr的位置，没有设置self，这种情况是一定要写个类的实例才行吗？

 

错误提示是缺少addr的位置，原因是没有对类进行实例化。

TypeError: missing 1 required positional argument: 的错误解决方法：

1、实例化

2、加上修饰符@classmethod
