In order to get started with this web framework you have to create a virtual environment and install the dependencies.

virtualenv pynic
source pynic/bin/activate
pip install pycnic gunicorn requests sqlalchemy

First

You can execute the hello world example the following way.

gunicorn hello_world:app

Using another terminal you can send post requests aswell to the http://127.0.0.1:8000/ context route.

import requests
requests.post(url="http://127.0.0.1:8000/").text
#'{"message": "Thank you for your POST request!"}'

Second

You can run the second example with the following command.

gunicorn request_data:app

Send your request the following way.

import requests
requests.post(url="http://127.0.0.1:8000/?arg=asdasd&arg2=asdasda",data=json.dumps({"a":"b"})).text
#'{"request_data": {"a": "b"}, "ip": "127.0.0.1", "method": "POST", "args": {"arg": "asdasd", "arg2": "asdasda"}, "json_args": {}, "header": null, "a": "b"}'
