安装flask-restful:

pip install flask-restful

一、一个最小的Flask-RESTful API

原始的 Flask 实现接口的方式:

@app.route('/', methods=['GET'])
def hello():
    # return 'Welcome to Learn Flask!'
    return '<h1>男人至死是少年!</h1><img src="https://p6-tt.byteimg.com/origin/pgc-image/c60abf609033446699235934a433ec21?from=pc">'

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)
