windows platform python pyramid entry


Pyramid It's more popular Python Web frame , More flexible , It's also powerful . In recent projects , I plan to study . There are few online tutorials , And a lot of them are aimed at linux Platform , I am a windows The natives, so for those linux How do commands translate into windows Orders are a headache . Took time to learn , To maximize the value of time , Share it to help you save your study time .

The main learning materials are from the official website , Address the following :

https://docs.pylonsproject.org/projects/pyramid/en/latest/quick_tutorial/index.html

All orders are directed at windows platform

Python development tool :VS Code

Let's start from building pyramid Let's start with our first service .

1. Create an empty folder for the new project D:\Python_project\ms_study

2. Create a virtual environment for the project .D:\python_virtual\ms_study

Knowledge point 【 A virtual environment 】: because python The project references a lot of packages , Each project calls a different package , Generate some compiled files , Therefore, each project can have its own virtual compilation environment , It can isolate projects .

command :virtualenv Virtual environment directory name


 


3. Activate the virtual environment , Enter the virtual environment Directory D:\python_virtual\ms_study\Scripts, And use activate Command to activate . Install after activation pyramid package .

command :

activate

pip install pyramid


 
 

4. Choose the compilation environment : stay VS Code The lower left corner is shown in the picture Python 3.8.5 64-bit Click here to select the compiler tool , Here we choose the newly created virtual environment :d:\\python_virtual\\ms_study\\Scripts\\python.exe.

 


 

 


 

 


 

5. stay D:\Python_project\ms_study Under the new python File and add the code as follows :

Knowledge point :

1)configurator yes pyramid A very important class , It's a context management tool , Used to connect attempts and routes .

2)make_wsgi_app: Establish a compliance wsgi Agreed web application

3)make_server To establish web service

4)server.serve_forever You can make this web The service runs until your program is shut down

5) python use with as Statement operation context manager , Automatically allocate and release resources . amount to c# Inside using()

 


 

6. Click on F5 Choose the top one Python File


 

 

 

7. Enter the web address in the browser :http://localhost:6789/
