运行时Python服务器聊天问题

我一直在编写聊天程序，但后来出现了一个错误，导致服务器崩溃，因此下次我将无法使用相同的端口，因此再次运行时会出现socket.bind错误。如何修复？ 源代码：

import socket
from threading import Thread

def clientHandler():
    conn, addr = sock.accept()
    print addr, "is Connected"
    while 1:
        data = conn.recv(1024)
        if not data:
            break
        print "Received Message", repr(data)
HOST = ''
PORT = raw_input('PORT: ')
PORT = int(PORT)
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((HOST, PORT))
sock.listen(5)

print "Server is running......"

#Thread(target=clientHandler).start()
#Thread(target=clientHandler).start()
#Thread(target=clientHandler).start()

for i in range(5):
    Thread(target=clientHandler).start()


sock.close()

情况就是这样：

    Server is running......
Exception in thread Thread-5:
Traceback (most recent call last):
  File "C:\Python27\lib\threading.py", line 810, in __bootstrap_inner

    conn, addr = sock.accept()

    sock, addr = self._sock.accept()
  File "C:\Python27\lib\socket.py", line 170, in _dummy
    raise error(EBADF, 'Bad file descriptor')

现在如何将收到的消息发送给所有客户端？

您必须在服务器端调用的功能如下： -创建一个套接字 -将其绑定到端口 -听 -接受 -处理客户沟通

您有多个接受线程。然后关闭套接字，使所有接受都失败。 正确的方法是

while True:
    client, addr = sock.accept()
    Thread(target=clientHandler, args=(client, addr)).start()

您可以在一段时间后重新使用该端口。要立即重用它：sock.setsockoptsocket.SOL_SOCKET，SOCKET.SO_REUSEADDR，1非常有效！我将添加什么来向所有客户端发送收到的消息@丹尼尔

while True:
    client, addr = sock.accept()
    Thread(target=clientHandler, args=(client, addr)).start()
