1、需要安装的模块
pip install flask
pip install flask-restful
2、一个最小的接口像这样:
# coding=utf-8
from flask import Flask
import flask_restful
app = Flask(__name__)
api = flask_restful.Api(app)
class HelloWorld(flask_restful.Resource):
def get(self):
return {'hello': 'world'}
api.add_resource(HelloWorld, '/')
if __name__ == '__main__':
app.run(host='0.0.0.0')
3、资源丰富的路由—- put 、get
启动服务
# coding=utf-8
from flask import Flask,request
import flask_restful
from flask_restful import Resource
app = Flask(__name__)
api = flask_restful.Api(app)
todos={}
class HelloWorld(flask_restful.Resource):
def get(self):
return {'hello': 'world'}
class TodoSimple(Resource):
def get(self, todo_id):
return {todo_id: todos[todo_id]}
def put(self, todo_id):
todos[todo_id] = request.form['data']
return {todo_id: todos[todo_id]}
# api.add_resource(HelloWorld, '/')
api.add_resource(TodoSimple, '/<string:todo_id>')
if __name__ == '__main__':
app.run(host='0.0.0.0')
发送数据和取数据
# encoding: utf-8
import requests
import re
import time
time1=time.time()
from requests import put, get
html=put('http://localhost:5000/todo1', data={'data': 'Remember the milk'}).json()
print html
get_html=get('http://localhost:5000/todo1').json()
print get_html
结果
"D:\Program Files\Python27\python.exe" D:/PycharmProjects/learn2017/阿里巴巴接口调用.py
{u'todo1': u'Remember the milk'}
{u'todo1': u'Remember the milk'}

4、端点
很多时候在一个 API 中，你的资源可以通过多个 URLs 访问。你可以把多个 URLs 传给 Api 对象的 Api.add_resource() 方法。每一个 URL 都能访问到你的 Resource
api.add_resource(HelloWorld,
'/',
'/hello')
你也可以为你的资源方法指定 endpoint 参数。
api.add_resource(Todo,
'/todo/<int:todo_id>', endpoint='todo_ep')
