套接字上的 BrokenPipeError

Question

我使用 Python Socket 创建了一个 Messenger，当我使用两个客户端时，例如，当一个用户离开聊天时，第二个用户可以再发送 1-2 条消息，之后服务器停止接受来自其他用户的消息，这是一个众所周知的错误 Broken pipe 32。我理解错误的术语，也许错误在于我的服务器在 While True 循环中（一个循环包括用户执行的所有操作他们之间），因为有一个很棒的代码形式：

if not data:
    print(f'User {name1} leave')
    break

但是我需要它，因为没有它，服务器会直接飞走，如果做一个类似的机制，服务器仍然可以接收用户的信息。

希望相互理解，任何帮助都会被接受和感激。服务器和客户端代码如下：

server: 

import socket
import threading
import time

HOST = '127.0.0.1'
PORT = 8888

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind((HOST, PORT))

server.listen(15)
print(f'Server {HOST}:{PORT} start.')

users = [] 
sort = []


def crypto(text, key):
    encrypt = ''

    for i in text:
        encrypt += chr(ord(i) + key)

    return encrypt   


def listen_decode(user, addr):
    print(f'User IP-address {addr[0]} login..')
    sort.append(user) 
    user.send('Encode'.encode('utf-8'))
    user.send('Name'.encode('utf-8'))
    name1 = user.recv(1024).decode('utf-8')
    users.append(name1)

    
    while True:
        data = user.recv(1024).decode('utf-8')
        b1 = time.ctime()
        atribute = ' | '
        data_crypto = crypto(data, 4)
        print(f'{name1} sent message: {data_crypto} ' + atribute + '' + b1 + ' ')

        for i in sort:
            if(i != server and i != user):
                i.sendall(f'{name1} > {data}'.encode('utf-8'))
    
        if not data:
            print(f'User {name1} leave')
            break


def start_server():
    
    while True:
       user_socket, addr = server.accept()
       potok_info = threading.Thread(target=listen_decode, args=(user_socket, addr))
       potok_info.start()


if __name__ == '__main__':
    start_server()

Answer 1

perhaps the error lies on my server in a While True loop (a loop that includes all the actions that users carry out among themselves), because there is a fabulous code in the form:
if not data:
    print(f'User {name1} leave')
    break

您已经找到错误原因的位置。发生错误是因为服务器不断尝试发送给断开连接的客户端（在该代码上方的循环中）。要停止服务器尝试此操作，您只需在识别断开连接的那个地方从 sort（连接的客户端列表）中删除客户端，即。 e.在 break.

之前插入 sort.remove(user)
