這篇文章主要介紹了Python基本socket通信控制操作,結(jié)合實例形式分析了Python socket通信服務(wù)器端與客戶端相關(guān)操作技巧與注意事項,需要的朋友可以參考下

本文實例講述了Python基本socket通信控制操作。分享給大家供大家參考，具體如下：

python — 基本socket通信控制（控制在celie.txt文件中主機IP地址可以發(fā)送信息，并返回對應(yīng)的客戶端IP、時間戳、發(fā)送的信息）

客戶端代碼

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)#調(diào)用IPv4協(xié)議
s.connect((host,port))#連接主機與端口
s.send("up")#客戶端給服務(wù)器端發(fā)送數(shù)據(jù)“up”
s.close()
root@72129clent:~/python/snmp#

服務(wù)器短信代碼：

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#導(dǎo)入時間戳
import SocketServer
#讀取目錄下的celie.txt文件
host_status = {}#新建字典，使用IP地址作為KEY值。作用是來判斷每個客戶端IP多久與服務(wù)器通信一次的
f = open('celie.txt')#調(diào)用策略文檔，在里面的ip地址就可以通過，并發(fā)送信息
while True:
  line = f.readline().split()
  if len(line) == 0:break
  print line[0]#打印第一個IP地址信息
  host_status[line[0]] = []#給字典第一個設(shè)置為空，這樣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)#接收客戶端數(shù)據(jù)
    if self.client_address[0] in host_status.keys():#如果存在字典中的ip地址信息，就返回對應(yīng)客戶端發(fā)送的Ip、時間戳、信息
      #self.client_address為數(shù)組('192.168.72.129', 49109)的值。只要當(dāng)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地址值賦值有兩個值，因此新建個列表，存取兩個值時間戳與接收的信息
      #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)]
      #直接把元組append進字典
      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)#打印客戶端地址、操作的時間戳值與接收的數(shù)據(jù)
      #print host_status
    else:#不存在字典中，則如下提示信息
      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__":#當(dāng)自己運行時調(diào)用什么什么；當(dāng)被其他程序調(diào)用時調(diào)用什么什么,如果被其他程序調(diào)用了，下面代碼不執(zhí)行
  host,port = '',18000
  server = SocketServer.ThreadingTCPServer((host,port),myMonitorHandler)#調(diào)用TCP的多線程
  server.serve_forever()
root@kali:~/python/snmp#

腳本運行情況

服務(wù)器端運行：

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的客戶端運行：

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的客戶端運行：

192.168.72.1的snmpclinet.py腳本語句：

#!/usr/bin/python
# --*-- coding:utf-8 --*--
import socket
host,port = '192.168.72.130',18000
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)#調(diào)用IPv4協(xié)議
s.connect((host,port))#連接主機與端口
s.send("up")#客戶端給服務(wù)器端發(fā)送數(shù)據(jù)“up”
s.close()

192.168.72.1的客戶端運行：

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>

再次查看服務(wù)器端運行情況：
