[Python 2.7] Hello World cgi http Server, pythonhello

# Cgi http server
# Getting Started
Python 2.x is preferred to this simple demo. I'm using Python 2.7 over windows.
* Https://docs.python.org/2.7/library/cgihttpserver.html* https://docs.python.org/2.7/library/cgi.html
# Starting a CGIHTTPServer

$ Python-m CGIHTTPServer 8000 Serving HTTP on 0.0.0.0 port 8000...

# CGI Script, Hello World

$ Mkdir cgi-bin/

$ Vim cgi-bin/index. py Print "Content-Type: text/html" # HTML is following Print # blank line, end of headers
Print "<TITLE> CGI script output </TITLE>" Print "<H1> This is my first CGI script </H1>" Print "Hello, world! "

# Access
Browser the following link and a web page will return.

Http: // localhost: 8000/cgi-bin/index. py

This is my first CGI scriptHello, world!

Convert Python to CGI web page program

#! /Usr/bin/env python
#-*-Coding: UTF-8 -*-

# Enable debugging
Import cgitb; cgitb. enable ()

Print ("Content-Type: text/plain; charset = UTF-8 ")
Print ()

Print ("Hello World! ")

This is an example in the python document.
You need to change the server configuration
Change/usr/bin/env python to your python installation path.
Import the cgitb module to perform cgi.
In addition, pay attention to the format returned by the http request

You should use apache
Add
<Directory "/path">
Options + ExecCGI
AddHandler cgi-script. cgi. py
</Directory>
Where "/path" can execute the cgi program folder
Add the extension of the executable cgi program in AddHandler.

What is the difference between python 273 and 330? Why input print "Hello, World!" In Python273! "Press enter.

In Python 3.3.0, print has been used as a built-in function, which means you need to perform the following operations: print ("Hello, World! ") In Python 3.3.0, the number of parentheses after print cannot be small. In Python 2.7.3, brackets are not required after print. I think Beginners should still learn Python 2.7.3, because there are still many modules, such as pygame, that do not support Python 3.3.0 yet, and for beginners, the two have little difference in basic skills, many materials are written in versions earlier than 2.7.3 and have not been updated to 3.3.0. Therefore, you can learn Python 2.7.3 with confidence.
