本文实例为大家分享了python编写监听端的具体代码，供大家参考，具体内容如下

import socket import time import sys import string import struct import errno import binascii  #Definition ser_ip = 'localhost' ser_port = 15001 HEADER_LISTENER = "IIII" split_time = 4  class TcpClient:   def run_srv(self):   sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)    print ("Trying to connect server...")    addr = (ser_ip, ser_port)      print ("Connecting " + ser_ip + ":" + str(ser_port))    #Connect server   try:     sock.connect(addr)   except Exception,e:     print ("Error:%s" % (e))     sock.close()     sys.exit()    hl = struct.pack(HEADER_LISTENER,0,0,0,0)   header_len = len(hl)      while True:     try:       buf_recv = sock.recv(header_len)     buf_header = buf_recv[0:header_len]thread_id = struct.unpack("!4I" , buf_header)[0]     err_num = struct.unpack("!4I" , buf_header)[1]     com_num = struct.unpack("!4I" , buf_header)[2]     wait_num = struct.unpack("!4I" , buf_header)[3]     #print("header len %d, recv len %d,buf_header:%s,buf_recv:%s")%(header_len,len(buf_recv),binascii.hexlify(buf_header),binascii.hexlify(buf_recv))       print ("split time:%d")%(split_time)       print ("thread id :%d")%(thread_id)       print ("error nums:%d")%(err_num)       print ("compl nums:%d")%(com_num)       print ("wait nums:%d")%(wait_num)       print ("----------------------")     except Exception,e:       print ("Error:%s" % (e))       sock.close()       sys.exit()         if __name__ == '__main__':   if (len(sys.argv) >= 2):     ser_port = int(sys.argv[1])      client = TcpClient()   client.run_srv()
