所需依赖：

Flask

Flask-RESTful

Python2.7

备注：flask-restful不能和flask的render_template模板结合使用，因为restfulapi的设计不是为了在flask里直接返回html。

本文档不包含flask的认证登陆功能

restful说明

restful把所有url请求当做资源， 资源下的get方法对应get请求，post方法对应post请求，put方法对应put请求，delete方法对应delete请求。

get请求，post新增, put修改, delete删除

具体的url设计模式，参考文章:

1、目录结构

.├── assets│   ├── __init__.py│   ├── server.py│   ├── urls.py├── run.py

2、assets下文件配置

__init__.py

from flask import Blueprintassets_page = Blueprint('assets_page', __name__)import urls

urls.py

#coding:utf-8from assets import assets_page  from flask_restful import Resource, Apifrom server import Servers, Server api = Api(assets_page)#注册路由api.add_resource(Servers, '/servers')api.add_resource(Server, '/servers/<_id>')

server.py

#coding:utf-8from flask import requestfrom flask_restful import Resource, Apiclass Servers(Resource):   def get(self):     #返回所有数据     return 'this is data list'   def post(self):     #新增数据     data = request.get_json()     return 'add new data: %s'%data  class Server(Resource):   def get(self,_id):     #返回单条数据      return 'this data is %s'%_id   def delete(self,_id):     #删除单条数据     return 'delete data: %s'%_id   def put(self, _id):     #修改单条数据     data = request.get_json()     return 'put data %s: %s'%(_id, data)

3、run.py配置

#coding:utf-8from flask import Flask#导入蓝图实例from assets import assets_pageapp = Flask(__name__,            template_folder='templates',            static_folder='static',            )#注册蓝图app.register_blueprint(assets_page)if __name__ == '__main__':    app.run(host='0.0.0.0', port=5000, debug=True)

4、测试

在linux终端测试

#获取列表:  $ curl  127.0.0.1:5000/servers"this is data list"#新增数据  $ curl -X POST -H "Content-Type:application/json" -d '{"name":"yangr"}' 127.0.0.1:5000/servers"add new data: {u'name': u'yangr'}"  #修改数据  $ curl -X PUT -H "Content-Type:application/json" -d '{"name":"yangr"}' 127.0.0.1:5000/servers/2"put data 2: {u'name': u'yangr'}"  #删除数据  $ curl -X DELETE 127.0.0.1:5000/servers/3"delete data: 3"
