AttributeError: 类实例没有属性

Question

我不知道这里的错误是什么

我知道这很乱但是在客户端连接并发送消息后我得到了一个异常

这里的错误ID

Exception in thread Thread-1:

Traceback (most recent call last):

  File "C:\Heights\PortableApps\PortablePython2.7.6.1\App\lib\threading.py", line 810, in __bootstrap_inner

    self.run()

  File "C:\Heights\PortableApps\PortablePython2.7.6.1\App\lib\threading.py", line 763, in run

    self.__target(*self.__args, **self.__kwargs)

  File "C:\Users\Gadi Tepper\PycharmProjects\Connection1\functions.py", line 12, in check_available_message

    user_uid = user.user_uid

AttributeError: Message instance has no attribute 'user_uid'

这是功能

import time

from message import *

from user import *

def check_available_message(messages, users):

    while True:

        for message in messages:

            for user in users:

                user_uid = user.user_uid

                dest_uid = message.receiver_uid

                if user_uid == dest_uid:

                    print("got here")

                    send_message(messages, message, user.user_socket)

def send_message(messages, message, user_socket):

    print(message.sender_uid + " can send a message to: " + message.sender_uid)

    time.sleep(1)

    data = str((message.receiver_uid + "//" + message.sender_uid + "//" + message.data)).encode

    user_socket.send(data)

    messages.remove(message)

这些是对象

class User:

    def __init__(self, user_uid, user_socket):

        self.user_uid = user_uid

        self.user_socket = user_socket

class Message:

    def __init__(self, sender_uid, receiver_uid, data):

        self.sender_uid = sender_uid

        self.receiver_uid = receiver_uid

        self.data = data

Answer 1

你在向后传递你的论点。您像这样设置线程：target=check_available_message, args=(users, messages))但是您的方法需要消息作为第一个参数，用户作为第二个参数：def check_available_message(messages, users):

Answer 2

您的服务器中的参数顺序错误。在 functions.py 中，你正在接受check_available_message(messages, users)，在服务器中你有另一个订单 -args=(users, messages)
