Question

我正在尝试使用Python实现套接字编程。

server.py

import socket
from threading import Thread
try:
    from SocketServer import ThreadingMixIn, ForkingMixIn
    from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
except ImportError:
    from socketserver import ThreadingMixIn, ForkingMixIn
    from http.server import HTTPServer, BaseHTTPRequestHandler



#from SocketServer import ThreadingMIxIn
class ClientThread(Thread):

    def _init_(self,ip,port):
        Thread._init_(self)
        self.ip=ip
        self.port= port
        print ("[+] New server socket thread started for " + + ":" + str(port))

    def run(self):
        while True :
            data = conn.recv(2048)
            print ("Server received data:", data)
            MESSAGE = raw_input("Multithreaded Python Server : Enter response from sever Enter exit:")

            if MESSAGE == 'exit' :
        #break
                conn.send(MESSAGE) 


TCP_IP ='0.0.0.0'
TCP_PORT = 2024
BUFFER_SIZE = 20

tcpServer = socket.socket()
tcpServer.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
tcpServer.bind((TCP_IP,TCP_PORT))
threads=[]


while True:
    tcpServer.listen(4)
    print ("Multithreaded python server: Waiting for connections from tcp clients...")
    (conn ,(ip,port)) = tcpServer.accept()
    newthread=ClientThread(ip,port)
    newthread.start()
    threads.append(newthread)


for t in threads:
    t.join() #end

client.py

import socket

host=socket.gethostname()
port=2024
BUFFER_SIZE= 2000
MESSAGE = raw_input("tcpClientB: Enter message / Enter exit:")

tcpClientB =socket.socket()
tcpClientB.connect((host, port))

while MESSAGE !='exit':
    tcpClientB.send(MESSAGE)
    data=tcpClientB.recv(BUFFER_SIZE)
    print ("Client received data",data)
    MESSAGE=raw_input("tcpClientB: Enter message to continue/ Enter exit:")

tcpClientB.close()

当我尝试运行此操作时，首先server.py然后client.py，我收到server.py

的错误

Multithreaded python server: Waiting for connections from tcp clients...
Traceback (most recent call last):
  File "mserver.py", line 47, in <module>
    newthread=ClientThread(ip,port)
  File "/usr/lib/python2.7/threading.py", line 670, in __init__
    assert group is None, "group argument must be None for now"
AssertionError: group argument must be None for now

以及来自client.py的以下错误：

python client2.py 
tcpClientB: Enter message / Enter exit:exit
Traceback (most recent call last):
  File "mclient2.py", line 10, in <module>
    tcpClientB.connect((host, port))
  File "/usr/lib/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused

我不明白我做错了什么。当我在运行后在客户端输入exit时，它会给我SocketErr Errno. 111。

Answer 1

错误111表示“拒绝连接”。服务器拒绝连接，因为它由于Thread构造函数调用中的错误而崩溃。 python中的构造函数是__init__（双双下划线）。

您的程序只定义了一个方法 init 而不是构造函数，而Thread构造函数的第一个参数是一个组。

将您的服务器更改为

def __init__(self,ip,port):
        Thread.__init__(self)

Python中的套接字编程错误：＆＃34;组参数现在必须为None＆＃34;和＆＃34; SocketErr Errno。 111＆＃34;
