闲来无事,用python写个客户端与服务器端应答的程序,主要原理就是客户端通过tcp协议与服务器端通信,客户端给服务器端发送指令,服务器执行指令后把相应的结果返回给客户端,客户端打印结果,代码比较简单,不详细介绍。纯属娱乐。
服务器端代码,server_tcp.py
#!/usr/bin/env python # -*- coding:utf-8 -*- # #执行客户端发送过来的命令,并把执行结果返回给客户端 import socket, traceback, subprocess host = '' port = 51888 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind((host, port)) s.listen(1) while 1: try: client_socket, client_addr = s.accept() except Exception, e: traceback.print_exc() continue try: print 'From host:', client_socket.getpeername() while 1: command = client_socket.recv(4096) if not len(command): break print client_socket.getpeername()[0] + ':' + str(command) # 执行客户端传递过来的命令 handler = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE) output = handler.stdout.readlines() if output is None: output = [] for one_line in output: client_socket.sendall(one_line) client_socket.sendall("\n") client_socket.sendall("ok") except Exception, e: traceback.print_exc() try: client_socket.close() except Exception, e: traceback.print_exc()
2.客户端代码 client_tcp.py
#!/usr/bin/env python # -*- coding:utf-8 -*- # #给server端发送命令 import socket, sys, traceback host = '127.0.0.1' port = 51888 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) try: s.connect((host, port)) except Exception, e: msg = traceback.format_exc() print '连接错误:', msg input_command = raw_input('Input command:') s.send(input_command) # 利用shutdown()函数使socket双向数据传输变为单向数据传输 # 该参数表示了如何关闭socket。具体为:0表示禁止将来读;1表示禁止将来写;2表示禁止将来读和写 s.shutdown(1) print '发送完成.' print '收到内容:\n' while 1: buff = s.recv(4096) if not len(buff): break sys.stdout.write(buff)
3.启动server_tcp.py脚本,开始监听本机51888端口;接着启动client_tcp.py.
(1)客户端内容:
/usr/bin/python2.7 /home/wuguowei/PycharmProjects/xplan_script/test_process/client_tcp.py Input command:ls -l 发送完成. 收到内容: 总用量 20 -rw-r--r-- 1 root root 744 2月 10 14:44 client_tcp.py -rw-r--r-- 1 root root 877 2月 10 14:18 my_sub_process.py -rw-r--r-- 1 root root 1290 2月 10 14:45 server_tcp.py -rw-r--r-- 1 root root 493 2月 10 10:43 tcpclient.py -rw-r--r-- 1 root root 1168 2月 10 11:51 tcpserver.py ok Process finished with exit code 0
(2)服务器端信息
/usr/bin/python2.7 /home/wuguowei/PycharmProjects/xplan_script/test_process/server_tcp.py From host: ('127.0.0.1', 46993) 127.0.0.1:ls -l
