纯洁美丽。它化做雪花,用自己洁白的生躯覆盖在大地上。此时,一切都是银装素裹,一副冰清玉洁的模样。光秃秃的树枝上缀满了朵朵洁白的 "梨花 ",风一吹,花儿纷纷飘落,好似一只只银白色的蝴蝶在空中偏偏起舞。 "忽如一夜春风来,千树万树梨花开 ",这句诗不正是赞美冬天的吗?
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()
