服务器端代码,server_tcp.py
!/usr/bin/env python
–– coding:utf-8 ––
执行客户端发送过去的命令,并把执行后果返回给客户端
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)
# 执行客户端传递过去的命令
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 '连贯谬误:', 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
该参数示意了如何敞开 socket。具体为:0 示意禁止未来读;1 示意禁止未来写;2 示意禁止未来读和写
s.shutdown(1)
print ‘ 发送实现.’
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
发送实现.
