How to use python to write simple remote control, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Students who have just begun to learn programming may often ask, "what am I doing with this?" when you buy food, you take out your computer and write a program to calculate how much it is. "

In fact, this has a lot to do with everyone's knowledge and entry-selected language, most students will choose C language to start programming, although C language is simple, but process-oriented programming will always make people feel boring and at a loss as to what to do.

So let's do an interesting one now, make a super simple remote control software, well, it's actually a script at most.

Since it is remote control, two functions need to be identified:

1. Remote

That is, through the network access to external hosts (including the intranet), we can use the socket library encapsulated in Python to achieve remote transmission of text, files, video and so on.

Detailed introduction of Python socket

2. Control

Control, the simplest understanding is to execute commands, then we can use the os library in Python, we can execute Linux shell commands.

Detailed introduction of Python os

Here's the code, save it as a .py file, and then execute server.py before client.py.

Server side, saved as server.py

#! / usr/bin/envpython

#-*-coding:utf-8-*-

Importsocket

Import os

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

Line.bind (('server IP', listening port))

Line.listen (5)

Print ('waitingcommd- >')

WhileTrue:

Conn,addr=line.accept ()

Msg=conn.recv (1024)

If msg ='QQ:

Break

Print ('get commd:',msg)

Result=os.popen (msg) .read ()

Conn.send ('result:' + result)

Conn.close ()

Phone.close ()

The client is saved as client.py

#! / usr/bin/env python

#-*-coding:utf-8-*-

Import socket

While True:

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

Line.connect (('server IP', listening port))

Msg = str (raw_input ('please inputcommd:'))

Line.send (str (msg) .encode ('utf-8'))

Data=phone.recv (1024)

Print data

Line.close ()

The implementation results are as follows:

Server execution result

The result returned by the client after executing the ls command on the server
