Python note (8): web development and python note web development

# In Windows, two more things should be set for Unix systems.

 

(1)Design web applications with MVC

Model-view-controlle)

Model: code for storing web Application Data

View: Format and display the code on the web Application User Interface

Controller: code that binds web applications and provides business logic

(2)Recommended folder structure

 

 

WebAPP: custom

Cgi-bin: stores code

Data: stores data.

Images: stores images

Templates: storage Template

(3) CGI allows web servers to run programs

Create a python file (the following code is required to build a web server using python)

FromHttp. serverImportHTTPServer, CGIHTTPRequestHandler

Port = 8099
Httpd = HTTPServer (('', Port), CGIHTTPRequestHandler)
Print ('The port number is'+ Str (httpd. server_port ))
Httpd. serve_forever ()

 

(4)Run

Start. py is the file used to store the above Code.

 

 

Access:

 

 

 

 

 

(5)Source code

If you are interested, you can download it to the online storage.

Then, (1) create a project using pycharm (with your own IDE.

(2) copy the following files to the project.

 

 

(3) Right-click cgi-bin and set the following. (If you do not set direct import to your own module, an error will be reported.) In addition, generate_list.py and yate. change the absolute path in the code in the two files of py to your own path (I originally wanted to use the relative path, but I don't know why the IDE can run it when using the relative path, when running on the web server, an error is reported)

(4) Then you can run and access http: // localhost: 8099 (if the port number is changed, use the modified one)
