Python服务器客户端WinError 10057 [英] Python Server Client WinError 10057

问题描述

我正在使用socket模块在Python 3.3中创建服务器和客户端.我的服务器代码运行正常，但是此客户端代码返回错误.这是代码:

I'm making a server and client in Python 3.3 using the socket module. My server code is working fine, but this client code is returning an error. Here's the code:

import socket
import sys
import os

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_address = ('192.168.1.5', 4242)
sock.bind(server_address)

while True:
    command = sock.recv(1024)
    try:
        os.system(command)
        sock.send("yes")
    except:
        sock.send("no")

这是错误:

Error in line: command = sock.recv(1024)
OSError: [WinError 10057] A request to send or receive data was disallowed because the socket is not connected  and (when sending on a datagram socket using a sendto call) no address was supplied

到底是怎么回事?

推荐答案

您似乎对实际上何时连接到服务器感到困惑，因此请记住始终始终先绑定到本地端口.因此，此行:

It looks like you're confused about when you actually connect to the server, so just remember that you always bind to a local port first. Therefore, this line:

server_address = ('192.168.1.5', 4242)

应实际阅读:

server_address = ('', 4242)

然后，在无限循环之前，放入以下代码行:

Then, before your infinite loop, put in the following line of code:

sock.connect(('192.168.1.5', 4242))

您应该很好.祝你好运！

And you should be good to go. Good luck!

我想我应该对术语始终"保持谨慎.在这种情况下，您要先绑定到本地套接字.

I suppose I should be more careful with the term "always." In this case, you want to bind to a local socket first.
