Python基本socket通信控制操作示例

本文实例讲述了python基本socket通信控制操作。分享给大家供大家参考，具体如下：

python — 基本socket通信控制（控制在celie.txt文件中主机ip地址可以发送信息，并返回对应的客户端ip、时间戳、发送的信息）

客户端代码

root@72129clent:~/python/snmp# ls
snmpclenit.py tab.py
root@72129clent:~/python/snmp# cat snmpclenit.py
#!/usr/bin/python
# --*-- coding:utf-8 --*--
import socket
host,port = '192.168.72.130',18000
s = socket.socket(socket.af_inet,socket.sock_stream)#调用ipv4协议
s.connect((host,port))#连接主机与端口
s.send("up")#客户端给服务器端发送数据“up”
s.close()
root@72129clent:~/python/snmp#

服务器短信代码：

root@kali:~/python/snmp# ls
celie.txt snmpserver.py tab.py tab.pyc
root@kali:~/python/snmp# cat celie.txt
192.168.72.129 xuweibo
root@kali:~/python/snmp#
root@kali:~/python/snmp# cat snmpserver.py
#!/usr/bin/python
# --*-- coding:utf-8 --*--
import datetime#导入时间戳
import socketserver
#读取目录下的celie.txt文件
host_status = {}#新建字典，使用ip地址作为key值。作用是来判断每个客户端ip多久与服务器通信一次的
f = open('celie.txt')#调用策略文档，在里面的ip地址就可以通过，并发送信息
while true:
  line = f.readline().split()
  if len(line) == 0:break
  print line[0]#打印第一个ip地址信息
  host_status[line[0]] = []#给字典第一个设置为空，这样后面只要直接追加值就ok了
f.close()
class mymonitorhandler(socketserver.baserequesthandler):
  '''this is the monitor server'''
  def handle(self):
    recv_data = self.request.recv(1024)#接收客户端数据
    if self.client_address[0] in host_status.keys():#如果存在字典中的ip地址信息，就返回对应客户端发送的ip、时间戳、信息
      #self.client_address为数组('192.168.72.129', 49109)的值。只要当中的ip地址，因此取self.client_address[0]
      #把host_status字典中的self.client_address[0]值即ip地址值赋值有两个值，因此新建个列表，存取两个值时间戳与接收的信息
      #如：{'192.168.72.129': [(datetime.datetime(2017, 8, 20, 21, 29, 59, 415054), 'up')]}
      #host_status[self.client_address[0]] = [(datetime.datetime.now(),recv_data)]
      #直接把元组append进字典
      host_status[self.client_address[0]].append((datetime.datetime.now(),recv_data))
      print 'from %s : %s %s' %(self.client_address,datetime.datetime.now(),recv_data)#打印客户端地址、操作的时间戳值与接收的数据
      #print host_status
    else:#不存在字典中，则如下提示信息
      print "sorry, ip %s is not in the monitor list" % self.client_address[0]
    #打印出192.168.72.129 [(datetime.datetime(2017, 8, 20, 22, 1, 6, 705498), 'up')]
    for t,m in host_status.items():
      print t,m
if __name__ == "__main__":#当自己运行时调用什么什么；当被其他程序调用时调用什么什么,如果被其他程序调用了，下面代码不执行
  host,port = '',18000
  server = socketserver.threadingtcpserver((host,port),mymonitorhandler)#调用tcp的多线程
  server.serve_forever()
root@kali:~/python/snmp#

脚本运行情况

服务器端运行：

root@kali:~/python/snmp# lsof -i:18000
command  pid user  fd  type device size/off node name
python 14190 root  3u ipv4 45472   0t0 tcp *:18000 (listen)
root@kali:~/python/snmp# kill -9 14190
root@kali:~/python/snmp# python snmpserver.py
192.168.72.129

在celie.txt中192.168.72.129的客户端运行：

root@72129clent:~/python/snmp# python snmpclenit.py
root@72129clent:~/python/snmp# python snmpclenit.py
root@72129clent:~/python/snmp# python snmpclenit.py
root@72129clent:~/python/snmp# python snmpclenit.py
root@72129clent:~/python/snmp# python snmpclenit.py
root@72129clent:~/python/snmp#

不在celie.txt中192.168.72.1的客户端运行：

192.168.72.1的snmpclinet.py脚本语句：

#!/usr/bin/python
# --*-- coding:utf-8 --*--
import socket
host,port = '192.168.72.130',18000
s = socket.socket(socket.af_inet,socket.sock_stream)#调用ipv4协议
s.connect((host,port))#连接主机与端口
s.send("up")#客户端给服务器端发送数据“up”
s.close()

192.168.72.1的客户端运行：

c:\python27>python.exe snmpclinet.py
c:\python27>python.exe snmpclinet.py
c:\python27>python.exe snmpclinet.py
c:\python27>python.exe snmpclinet.py
c:\python27>python.exe snmpclinet.py
c:\python27>

再次查看服务器端运行情况：

root@kali:~/python/snmp# lsof -i:18000
command  pid user  fd  type device size/off node name
python 14190 root  3u ipv4 45472   0t0 tcp *:18000 (listen)
root@kali:~/python/snmp# kill -9 14190
root@kali:~/python/snmp# python snmpserver.py
