Python 3.7.5 : Testing the Falcon framework - part 001.

I start the new year with this python framework named Falcon.
The Falcon is a low-level, high-performance Python framework for building HTTP APIs, app backends, and higher-level frameworks.
The main reason was the speed of this python framework, see this article about falcon benchmark.
You can see is more faster like Flask and Django.
The instalation is easy with pip tool, you can read also the documenation webpage:

[mythcat@desk projects]$ mkdir falcon_test
[mythcat@desk projects]$ cd falcon_test/
[mythcat@desk falcon_test]$ pip3 install falcon --user
Collecting falcon
...
Successfully installed falcon-2.0.0

Falcon also fully supports CPython 2.7 and 3.5+.
If you want to install the latest beta or release candidate use:

[mythcat@desk falcon_test]$ pip3 install --pre falcon --user

The Falcon framework is easy to use.
First, I created a folder named test001 for my falcon application script named app.py:

[mythcat@desk falcon_test]$ mkdir test001
[mythcat@desk falcon_test]$ cd test001/
[mythcat@desk test001]$ vim app.py

In this python script I used python packages json and falcon with a class named req_class:

import json
import falcon

class req_class:
    def on_get(self,req,resp):
        print("on_get class")
my_falcon_api = falcon.API()
my_falcon_api.add_route('/test',req_class())

The url route is set to test.
To test the falcon framework we need the Gunicorn python package.
The Gunicorn is working on my Fedora Linux distro and I'm not sure if working Gunicorn on Windows.
You can try on Windows O.S. the waitress python package.

[mythcat@desk falcon_test]$ pip3 install gunicorn --user
Collecting gunicorn
...
Successfully installed gunicorn-20.0.4

To test this simple Falcon application use this command line where the app python script and my falcon variable A.P.I. named my_falcon_api is used.

[mythcat@desk test001]$ gunicorn app:my_falcon_api

Open in the browser this URL with the route I set: http://127.0.0.1:8000/test.
You will don't see anything in the browser but will see the python output of the print function for my request.
