Creating a simple Web page tutorial instance using the CGI module

The last few days have been learning Python web programming, the main content is to build a simple Web server and the use of CGI modules to build a simple Web page (the word is not professional enough to forgive).

There are three types of modules that Python uses to build HTTP server:
1) Basehttpserver: Provide basic Web services and processor classes, respectively, Httpserver and Basehttprequesthandler;
2) Simplehttpserver: Contains the Simplehttprequesthandler class that performs the get and head requests;
3) Cgihttpserver: Contains the Cgihttprequesthandler class that handles post requests and executions.

Python's simplest Web server looks like this:

So you can access the contents of the server

For example, direct access to the following HTML page results in the following:

The hello.html is stored in the root directory of the server and the code is as follows:

<meta http-equiv= ' content-type ' content= ' text/html; Charset=utf-8 ' >
In the hello.html file is linked to a hello_get.py, the file is stored in the server root directory under the Cgi-bin folder, the code is as follows:


#!/usr/bin/python# Import modules for CGI handlingimport CGI, cgitb# Create instance of fieldstorageform = CGI. Fieldstorage () # Get data from fieldsfirst_name = Form.getvalue (' first_name ') last_name  = Form.getvalue (' last_name ') ) print "content-type:text/html\r\n\r\n" print "
In the previous image of the page to enter information, click Submit, the results are as follows:



It's worth noting that I've been doing this for a long time, calling the Py file to either show a blank or go wrong. View a lot of network resources, found that the problem is the permissions of the Py file, only need to execute chmod 755 xxx.py. In addition

#!/usr/bin/python It is best not to have any other information, I found the above to protect the following information is not displayed

I am also just a beginner, can only say that my study process to share, to avoid people meet me the same problem and spend a lot of time.
