Python编写的客户端给服务器发送指令执行相应的命令并返回结果，python编写,闲来无事，用python

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。

1.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, subprocesshost = ''port = 51888s = 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, tracebackhost = '127.0.0.1'port = 51888s = 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:', msginput_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：```python/usr/bin/python2.7 /home/wuguowei/PycharmProjects/xplan_script/test_process/client_tcp.pyInput 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.pyokProcess finished with exit code 0
