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.pytab.py
root@72129clent:~/python/snmp#catsnmpclenit.py
#!/usr/bin/python
#--*--coding:utf-8--*--
importsocket
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.txtsnmpserver.pytab.pytab.pyc
root@kali:~/python/snmp#catcelie.txt
192.168.72.129xuweibo
root@kali:~/python/snmp#
root@kali:~/python/snmp#catsnmpserver.py
#!/usr/bin/python
#--*--coding:utf-8--*--
importdatetime#导入时间戳
importSocketServer
#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
whileTrue:
line=f.readline().split()
iflen(line)==0:break
printline[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()
classmyMonitorHandler(SocketServer.BaseRequestHandler):
'''ThisistheMonitorserver'''
defhandle(self):
recv_data=self.request.recv(1024)#接收客户端数据
ifself.client_address[0]inhost_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
#printhost_status
else:#不存在字典中，则如下提示信息
print"sorry,ip%sisnotinthemonitorlist"%self.client_address[0]
#打印出192.168.72.129[(datetime.datetime(2017,8,20,22,1,6,705498),'up')]
fort,minhost_status.items():
printt,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 COMMANDPIDUSERFDTYPEDEVICESIZE/OFFNODENAME python14190root3uIPv4454720t0TCP*:18000(LISTEN) root@kali:~/python/snmp#kill-914190 root@kali:~/python/snmp#pythonsnmpserver.py 192.168.72.129
在celie.txt中192.168.72.129的客户端运行：
root@72129clent:~/python/snmp#pythonsnmpclenit.py root@72129clent:~/python/snmp#pythonsnmpclenit.py root@72129clent:~/python/snmp#pythonsnmpclenit.py root@72129clent:~/python/snmp#pythonsnmpclenit.py root@72129clent:~/python/snmp#pythonsnmpclenit.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--*--
importsocket
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.exesnmpclinet.py C:\Python27>python.exesnmpclinet.py C:\Python27>python.exesnmpclinet.py C:\Python27>python.exesnmpclinet.py C:\Python27>python.exesnmpclinet.py C:\Python27>
