本文实例讲述了python使用socket 先读取长度,在读取报文内容。分享给大家供大家参考，具体如下：
tlpmts1:~/sbin # cat test9105.py
# -*- coding: utf-8 -*-
import SocketServer
import socket
import time
import sys
reload(sys)
print time.ctime()
sys.setdefaultencoding('utf-8')
class SMSsendx (object):
def Sms(self):
#.decode('utf-8').encode('gbk')
host='10.4.160.71'
port = 9105
print 'host'+'->'+host
print 'port'+'->'+str(port)
bufsize=10240
addr=(host,port)
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.settimeout(20)
s.connect((host,port))
data=''
