您好，我尝试使用python套接字连接客户端和服务器...双方（客户端和服务器）都在正常工作...问题：当我尝试将客户端连接到服务器时，它给出以下信息错误。

Traceback (most recent call last):
  File "tcpclient.py", line 8, in <module>
    client.connect((hos,po))
  File "/usr/lib/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused

我尝试使用 netcat 监听端口......它工作了这是我的代码

服务器 ：

mport socket
import threading

ip = "0.0.0.0"
po = 9999

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

server.listen(5)

print "[*] Listining on %s:%d" %(ip,po)

def handle_client(client_socket):
        request = client_socket.recv(1024)
        print "[*] Received: %s" % request
        client_socket.close()

while True :
        client,addr = server.accept()
        print "[*] Accepted connection from %s:%d" %(addr[0],addr[1])
        client_handler = threading.Thread(target=handle_client,args=(client,))
        client_handler.start()

客户 ：

import socket

hos =  "127.0.0.1"
po = 9999

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

client.connect((hos,po))

client.send("Hello")

re = client.recv(3456)
print re

代码应该是这样的：

import socket
import threading

ip = "0.0.0.0"
po = 9999

server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server.bind((ip,po))# This line was missing :p thanks
server.listen(5)

print "[*] Listining on %s:%d" %(ip,po)

def handle_client(client_socket):
        request = client_socket.recv(1024)
        print "[*] Received: %s" % request
        client_socket.close()

while True :
        client,addr = server.accept()
        print "[*] Accepted connection from %s:%d" %(addr[0],addr[1])
        client_handler = threading.Thread(target=handle_client,args=(client,))
        client_handler.start()
