Question

我试图创建一个连接两台（或更多台）计算机的小聊天程序，所以我尝试了这个：

    import socket

    tcpSocket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

    tcpSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)

    tcpSocket.bind(("0.0.0.0",8000))

    tcpSocket.listen(3)

    print "Waiting for a Client ... "
    (client, (ip,sock)) = tcpSocket.accept()

    print "Received connection from : ",ip

    print "Starting ECHO output ..."

    data = 'dump'

    client.send("Enter you're name : ")
    name=client.recv(1024)
    name=name.strip()

    while len(data) :
        send_data = raw_input("Me : ")
        try :
            client.send("Server : "+send_data)
            client.send("\n"+name+" : ")
        except :
            print "Connection lost !"
            break
        data = client.recv(2048)
        data = data.strip()
        print name+" : "+data

    print "Closing connection ..."
    client.close()

    print "Shutting down server ..."
    tcpSocket.close()

它运作良好，唯一的问题是我无法将多台计算机连接到服务器！我通过使用这个功能尝试了线程模块：

import socket
import thread

def thread_send() :



print "Received connection from : ",ip

    print "Starting ECHO output ..."

    data = 'dump'

    client.send("Enter you're name : ")
    name=client.recv(1024)
    name=name.strip()

    while len(data) :
        send_data = raw_input("Me : ")
        try :
            client.send("Server : "+send_data)
            client.send("\n"+name+" : ")
        except :
            print "Connection lost !"
            break
        data = client.recv(2048)
        data = data.strip()
        print name+" : "+data


tcpSocket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

tcpSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)

tcpSocket.bind(("0.0.0.0",8000))

tcpSocket.listen(5)

print "Waiting for a Client ... "

(client, (ip,sock)) = tcpSocket.accept()

for i in range(5) :

    thread.start_new_thread(thread_send,())

while True :
    pass

print "Closing connection ..."
client.close()

print "Shutting down server ..."
tcpSocket.close()

但它不起作用：/

以下是您如何操作的示例。对不起，我没有测试过这段代码，也没有运行它来检查是否有任何语法问题，这只是为了给出一个想法。


def thread_send(cli_sock):
    data = 'dump'

    cli_sock.send("Enter you're name : ")
    name=cli_sock.recv(1024)

    if len(name) == 0:   ## If client disconnected or terminated
        return

    name=name.strip()

    while len(data) :
        send_data = raw_input("Me : ")
        try :
            cli_sock.send("Server : "+send_data)
            cli_sock.send("\n"+name+" : ")
        except :
            print "Connection lost !"
            break
        data = client.recv(2048)
        data = data.strip()
        print name+" : "+data



serv_sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serv_sock.bind(('localhost', 8080))
serv_sock.listen(1)
print "After listen...waiting for accept\n"
try:
    while True:
        client_sock, address = serv_sock.accept()
        print "Connection accepted\n"
        thread.start_new_thread(thread_send, (client_sock))
finally:
    serv_sock.close()
