Python中的套接字编程错误：“组参数现在必须为None”和“SocketErr Errno。111”

问题描述：

我正在尝试使用Python实现套接字编程。Python中的套接字编程错误：“组参数现在必须为None”和“SocketErr Errno。111”

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()

当我试图运行这一点，首先server.py然后client.py，我得到这个错误server.py

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

，并从client.py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

我不明白我在做什么错。当我在运行后输入exit后，它给我SocketErr Errno. 111。

'_init_' - >'__init__' –

答

errno 111表示'连接被拒绝'。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__（双重双下划线）。

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

服务器更改为

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