服务端:


    #!/usr/bin/env
    import SocketServer
    class myMonitorHandler(SocketServer.BaseRequestHandler):
     def handle(self):
      self.data=self.request.recv(1024).strip()
      print "From %s : %s" %(self.client_address,self.data)
    if __name__=="__main__":
     HOST,PORT='0.0.0.0',18000
     server=SocketServer.ThreadingTCPServer((HOST,PORT),myMonitorHandler)
     server.serve_forever()
     server.close()

客户端:


    #!/usr/bin/env python
    import socket
    host,port="10.23.30.191",18000
    s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    s.connect((host,port))
    s.send("UP")
    ~ 

服务端运行结果:
From ('10.23.30.61', 45809) : UP
From ('10.23.30.61', 45810) : UP
From ('10.23.30.61', 45811) : UP
From ('10.23.30.61', 45812) : UP
From ('10.23.30.61', 45813) : UP
From ('10.23.30.61', 45814) : UP
From ('10.23.30.61', 45815) : UP

python 简单的多线程链接(二)

一。简单的多线程(服务器端添加了时间标签)
1.1 服务端


    #!/usr/bin/env
    import datetime
    import SocketServer
    classmyMonitorHandler(SocketServer.BaseRequestHandler):
        def handle(self):
           self.data=self.request.recv(1024).strip()
            print "From %s : %s  :%s"%(self.client_address,datetime.datetime.now(),self.data)
    if__name__=="__main__":
        HOST,PORT='0.0.0.0',18000
       server=SocketServer.ThreadingTCPServer((HOST,PORT),myMonitorHandler)
        server.serve_forever()
        server.close()

1.2 客户端:


    #!/usr/bin/envpython

    import socket

    host,port="192.168.1.103",18000
    s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    s.connect((host,port))
    s.send("UP")

结果:
From('192.168.1.104', 58032) : 2013-12-24 06:47:03.620356 :UP
From('192.168.1.104', 58033) : 2013-12-24 06:47:05.464851 :UP
From('192.168.1.104', 58034) : 2013-12-24 06:47:06.273092 :UP

二.服务器端添加时间标签后(判断30秒更新发送)

2.1 首先要有字典存放客户端的信息
先定义1个空字典


    #!/usr/bin/env
    importdatetime
    importSocketServer
    host_status={}

    f=open('client.txt')
    while 1:
        line=f.readline().split()
        if len(line)==0:break
        host_status[line[0]]= []
    f.close()

    classmyMonitorHandler(SocketServer.BaseRequestHandler):
        def handle(self):
           self.data=self.request.recv(1024).strip()
            if self.client_address[0] inhost_status.keys():
               host_status[self.client_address[0]].append((datetime.datetime.now(),self.data))
                print "From %s :%s  :%s"%(self.client_address,datetime.datetime.now(),self.data)
            else:
                print "sorry,IP %sis't in the monitor list!" %self.client_address[0]
            for t,m in host_status.items():
                print t,m

    if__name__=="__main__":
        HOST,PORT='0.0.0.0',18000
       server=SocketServer.ThreadingTCPServer((HOST,PORT),myMonitorHandler)
        server.serve_forever()
        server.close()

解释:


    #!/usr/bin/env
    import datetime
    import SocketServer
    host_status={} #定义个空子典用来存储客户端发送的信息和时间

    f=open('client.txt') #文件的读取
    while 1:
        line=f.readline().split() #文件的读取并分段
        if len(line)==0:break  #结尾退出
    host_status[line[0]]= [] #初始化字典,把文件中的ip设置为字典的key
    f.close()

    classmyMonitorHandler(SocketServer.BaseRequestHandler):
        def handle(self):
           self.data=self.request.recv(1024).strip()
            ifself.client_address[0] in host_status.keys():#如果获取客户端ip在字典的列表的key中
               host_status[self.client_address[0]].append((datetime.datetime.now(),self.data)) #这儿采用追加的方式
                print"From %s : %s  :%s"%(self.client_address,datetime.datetime.now(),self.data)#输出客户端的ip ,连接时间,发送的内容
            else:
                print"sorry,IP %s is't in the monitor list!" %self.client_address[0]#不在提示
            for t,m inhost_status.items():#字典输出
                printt,m  #字典的输出

    if__name__=="__main__":
        HOST,PORT='0.0.0.0',18000
       server=SocketServer.ThreadingTCPServer((HOST,PORT),myMonitorHandler)
        server.serve_forever()
        server.close()
