服务端:

#!/usr/bin/envimport SocketServerclass 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 pythonimport sockethost,port="10.23.30.191",18000s=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/envimport datetimeimport SocketServerclassmyMonitorHandler(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/envpythonimport sockethost,port="192.168.1.103",18000s=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/envimportdatetimeimportSocketServerhost_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,mif__name__=="__main__":    HOST,PORT='0.0.0.0',18000   server=SocketServer.ThreadingTCPServer((HOST,PORT),myMonitorHandler)    server.serve_forever()    server.close()

解释:

#!/usr/bin/envimport datetimeimport SocketServerhost_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keyf.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()
