閒來無事可做,用python寫個客戶端與伺服器端應答的程序,主要原理就是客戶端透過tcp協定與伺服器端通信,客戶端給伺服器端發送指令,伺服器執行指令後把相應的結果傳回給客戶端,客戶端列印結果,程式碼比較簡單,不詳細介紹。純屬娛樂。
伺服器端程式碼,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.客戶端程式碼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.啟動server_tcp.py腳本,開始監聽本機接合. (1)客戶端內容:
/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)伺服器端資訊
/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
