閒來無事，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通過tcp協議與伺服器端通信，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返回給客戶端，客戶端列印結果，代碼比較簡單，不詳細介紹。純屬娛樂。
#!/usr/bin/env python
# -*- coding:utf-8 -*-
# #執行客戶端發送過來的命令，並把執行結果返回給客戶端
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)
# 執行客戶端傳遞過來的命令
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.客戶端代碼 client_tcp.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
# #給server端發送命令
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 '連接錯誤:', msg
input_command = raw_input('Input command:')
s.send(input_command)
# 利用shutdown()函數使socket雙向數據傳輸變為單向數據傳輸
# 該參數表示了如何關閉socket。具體為：0表示禁止將來讀；1表示禁止將來寫；2表示禁止將來讀和寫
s.shutdown(1)
print '發送完成.'
print '收到內容：\\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51888埠；接著啟動client_tcp.py.
(1)客戶端內容：
/usr/bin/python2.7 /home/wuguowei/PycharmProjects/xplan_script/test_process/client_tcp.py
Input command:ls -l
發送完成.
收到內容：
總用量 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
