安装flask-restful
from flask import Flask
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app) //封装app


class HelloWorld(Resource):
    def get(self,todo_id):
        return {"name":"alex"}

　　def put(self,todo_id):
　　　　pass

api.add_resource(HelloWorld,'/<string:todo_id>') //路由,资源和url建立映射关系
一种资源只能添加一次,#url匹配到http://127.0.0.1:5000/todo.?  

if __name__ == "__main__": app.run(debug=True,host="0.0.0.0")
