restful
Flask-RESTful 提供了一个Resource基础类，能够定义一个给定URL的一个或者多个HTTP方法。
上一篇TODO list应用改用Flask_RESTful的完整示例代码：
from flask import Flask, abort, url_for, make_response, jsonify
from flask_restful import Resource, Api, reqparse, fields, marshal
from flask_httpauth import HTTPBasicAuth
app = Flask(__name__)
api = Api(app)
auth = HTTPBasicAuth()
tasks = [
{
'id':1,
'title':'白鹿原',
'description':'这是一定死啦塞啊；阿凯骄傲灵丹安矿鉴定暗访东方三；啊反馈；安静快撒娇扥卡机',
'done':False
},
{
'id':2,
'title':'嫌疑人',
'description':'as大肯借；额看课文静安寺放大反抗航将；来否；付定金奥兰多 看企鹅长恨东澳岛啊；伐开森',
'done':False
}
]
task_fields = {
'title': fields.String,
'description': fields.String,
'done': fields.Boolean,
'uri': fields.Url('task')
}
