sockets - 套接字编程Python

Question

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('localhost', 8021))
s.listen(10)

while True:
    conn, addr = s.accept()
    print 'got connected from', addr
    s.send("sending to client")
    conn.close()
    s.close()

问题是我运行客户端代码后，它显示 "got connected from ('127.0.0.1', 52764)"，但随后显示错误

Traceback (most recent call last):
  File "D:\Python27\server", line 13, in <module>
    s.send("sending to client")
error: [Errno 10057] A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied

我该如何纠正？

我的客户代码是:

import socket

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

host = 'localhost'
port = 8021


s.connect((host, port))

revieved = s.recv(1024)
print "Recieved: ", recieved

好吧，答案很简单，我在这里可能会赢得一些声誉!

您正在将常规套接字与特定的客户端连接混淆。运行s.accept()会收到一个元组，该元组包括:远程套接字连接对象和远程套接字地址。这样，您可以通过引用正确的连接对象来与特定的客户端对话。

因此，固定内容可能如下所示:

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('localhost', 8021))
s.listen(10)

while True:
    conn, addr = s.accept()
    print 'got connected from', addr
    conn.send("sending to client")
    conn.close()
    s.close()

假设其他一切都正常!
