Question

此Python代码存在问题。请帮我。谢谢

import sys
import socket
import select

HOST = 'sys.ase.ro'
SOCKET_LIST = []
RECV_BUFFER = 4096
PORT = 6508


def chat_server():
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server_socket.bind((HOST, PORT))
    server_socket.listen(10)

    SOCKET_LIST.append(server_socket)

    print "Chat server started on port " + str(PORT)

    while 1:


        ready_to_read, ready_to_write, in_error = select.select(SOCKET_LIST, [], [], 0)

        for sock in ready_to_read:

            if sock == server_socket:

                sockfd, addr = server_socket.accept()

                SOCKET_LIST.append(sockfd)
                print "Client (%s, %s) connected" % addr

                broadcast(server_socket, sockfd, "[%s:%s] entered our chatting room\n" % addr)


            else:

                try:

                    data = sock.recv(RECV_BUFFER)
                    if data:

                        broadcast(server_socket, sock, "\r" + '[' + str(sock.getpeername()) + '] ' + data)
                    else:

                        if sock in SOCKET_LIST:
                            SOCKET_LIST.remove(sock)


                        broadcast(server_socket, sock, "Client (%s, %s) is offline\n" % addr)


                except:
                    broadcast(server_socket, sock, "Client (%s, %s) is offline\n" % addr)
                    continue

    server_socket.close()


# broadcast chat messages to all connected clients
def broadcast(server_socket, sock, message):
    for socket in SOCKET_LIST:

        if socket != server_socket and socket != sock:
            try:
                socket.send(message)
            except:

                socket.close()

                if socket in SOCKET_LIST:
                    SOCKET_LIST.remove(socket)


if __name__ == "__main__":
    sys.exit()

错误看起来像：

Traceback (most recent call last):   File
"C:/Users/Admin/PycharmProjects/untitled/chat_server.py", line 90, in
<module>
sys.exit(chat_server())   File "C:/Users/Admin/PycharmProjects/untitled/chat_server.py", line 20, in
chat_server
server_socket.bind((HOST,PORT))   File "C:\Python27\Lib\socket.py", line 222, in meth
return getattr(self._sock,name)(*args) socket.error: [Errno 10049] The requested address is not valid in its context

Answer 1

您正在尝试将套接字绑定到远程地址。来自windows documentation：

bind函数将本地地址与套接字相关联。

改为使用connect：

server_socket.connect((HOST, PORT))

Answer 2

我弄清楚为什么它不起作用我的代码失败的原因是因为我试图绑定到外部主机名。我的机器不知道该主机名，因此错误消息。我在localhost中对其进行了更改，并且可以正常工作。

程序python套接字
