我正在自学Python网络,我回想起当我自学线程时,我遇到了这个页面,所以我复制了脚本,为Python 3.1.1更新了它们并运行它们.他们工作得很好.

然后我做了一些修改.我的目标是做一些简单的事情:

1. 客户端挑选一个整数并将其发送到服务器.
2. 服务器接收pickle整数,取消它,将其加倍,然后将其pickle并将其发送回客户端.
3. 客户端接收pickle(和doubled)整数,取消它并输出它.

这是服务器:

import pickle
import socket
import threading

class ClientThread(threading.Thread):
    def __init__(self, channel, details):
        self.channel = channel
        self.details = details
        threading.Thread.__init__ ( self )

    def run(self):
        print('Received connection:', self.details[0])
        request = self.channel.recv(1024)
        response = pickle.dumps(pickle.loads(request) * 2)
        self.channel.send(response)
        self.channel.close()
        print('Closed connection:', self.details [ 0 ])

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('', 2727))
server.listen(5)

while True:
    channel, details = server.accept()
    ClientThread(channel, details).start()

这是客户:

import pickle
import socket
import threading

class ConnectionThread(threading.Thread):
    def run(self):
        client = …

我正在调试一个过去有效的简单程序.我已经挑出了发生错误的指令,但我无法弄清楚是什么触发它.我已经阅读了与WinError 10061相关的所有问题,但我没有看到明确的答案
