我目前正在编写我的第一个基本套接字服务器，我偶然发现了服务器与客户端通信的两种不同形式 - 线程（我认为conn在 python 中使用）和channels，我不太了解 - 但它们看起来像客户端和服务器之间通信的另一种方式。两者之间有什么区别以及如何最好地使用它们？

这是要求的代码-请原谅我的N00biness :)

连接/线程

def clientthread(conn):

    #Sending message to connected client
    #This only takes strings (words)
    conn.send("Welcome to the server. Type something and hit enter\n")

    #loop so that function does not terminate and the thread does not end
    while True:

        #Receiving from client
        data = conn.recv(1024)
        if not data:
            break
        conn.sendall(data)
        print data


    #To close the connection
    conn.close()

while True:

    #Wait to accept a connection - blocking call
    conn, addr = s.accept()
    #display client information (IP address)
    print 'Connected with ' + addr[0] + ':' + str(addr[1])

    #Start new thread takees 1st argument as a function name to be run, second
    #is the tuple of arguments to the function

    start_new_thread(clientthread ,(conn,))

频道

while True:

    #Wait to accept a connection - blocking call
    channel, details = s.accept()
    #display client information (IP address)
    print 'Connected with ', details

    #Start new thread takees 1st argument as a function name to be run, second
    #is the tuple of arguments to the function

    #Sending message to connected client
    #This only takes strings (words)
    intro = "Welcome to the server. Type something and hit enter"
    print channel.recv(len(intro))

    channel.send(intro)

    #loop so that function does not terminate and the thread does not end
    while True:

        #Receiving from client
        data = channel.recv(1024)
        if not data:
            break
        channel.sendall(data)
        print data

channel除了一种用途和另一种用途之外，它们做的事情完全相同conn。
