Python多线程TCP通讯

import threading
import socket

encoding = ‘utf-8’
BUFSIZE = 1024

a read thread, read data from remote

class Reader(threading.Thread):
def init(self, client):
threading.Thread.init(self)
self.client = client

def run(self):
    while True:
        data = self.client.recv(BUFSIZE)
        if (data):
            string = bytes.decode(data, encoding)
            print(string, end='')
        else:
            break
    print("close:", self.client.getpeername())

def readline(self):
    rec = self.inputs.readline()
    if rec:
        string = bytes.decode(rec, encoding)
        if len(string) > 2:
            string = string[0:-2]
        else:
            string = ' '
    else:
        string = False
    return string

a listen thread, listen remote connect

when a remote machine request to connect, it will create a read thread to handle

class Listener(threading.Thread):
def init(self, port):
threading.Thread.init(self)
self.port = port
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
self.sock.bind((“0.0.0.0”, port))
self.sock.listen(0)

def run(self):
    print("listener started")
    while True:
        client, cltadd = self.sock.accept()
        Reader(client).start()
        cltadd = cltadd
        print("accept a connect")

lst = Listener(9011) # create a listen thread
lst1=Listener(9010)
lst1.start()
lst.start() # then start

# #6、发送给对方数据

# if rect_data:

# else:

# break

# client_socket.close()

# #7、关闭套接字

# #client_socket.close()
