Socket 多线程FTP软件开发

Socket具体还可见360云中文档记载

Socket是一个非常古老的协议了 1970年

Socket.AF_Unix======AF意思是  addressFamily 地址簇

Import os

Os.system(data)  #执行命令

cmd=Os.popen(data).read() #执行命令 并返回结果

Import commands

Status,command=Commands.getstatusoutput(data) #执行命令 返回结果状态，和结果内容

Sever端

#Echo server program

import socket

import commands

HOST='192.168.18.99' #Symbolic name meaning all available interfaces

PORT=50007      #Arbitrary non-privileged port

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.bind((HOST,PORT))

s.listen(1)

while 1:

conn,addr=s.accept()

print 'Connected by',addr

while(1):

data=conn.recv(1024)

if not data:

break

print 'Command received from %s:%s' % addr,data

status,cmd_result=commands.getstatusoutput(data)

conn.sendall(cmd_result)

conn.close()

Client端

#Echo Client program

import socket,time

HOST='192.168.18.99' #Server IP

PORT=50007      #Server Port

s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.bind((HOST,PORT))

s.listen(1)

while 1:

cmd=raw_input("Your command is:").strip()

if cmd=='':

continue

s.sendall(cmd)

data=s.recv(4096)

time.sleep(2)

print data

s.close()

SocketServer自带多线程

if __name__==’__main__’:当自调用的时候，执行下面的代码，当被别的模块调用的时候，冒号下面的代码不被执行
