1. 安装，有两种安装方式
Install Flask-RESTful with pip
pip install flask-restful
The development version can be downloaded from its page at GitHub.
git clone https://github.com/flask-restful/flask-restful.git
cd flask-restful
python setup.py develop
2.使用
A Minimal API
A minimal Flask-RESTful API looks like this:
from flask import Flask
from flask_restful import Resource, Api
app = Flask(__name__)
api = Api(app)
class HelloWorld(Resource):
def get(self):
return {'hello': 'world'}
api.add_resource(HelloWorld, '/')
if __name__ == '__main__':
app.run(debug=True)
Save this as api.py and run it using your Python interpreter. Note that we’ve enabled Flask debugging mode to provide code reloading and better error messages.
$ python api.py
* Running on http://127.0.0.1:5000/
* Restarting with reloader
Warning
Debug mode should never be used in a production environment!
Now open up a new prompt to test out your API using curl
$ curl http://127.0.0.1:5000/
{"hello": "world"}
