tornado简单实现restful接口

tornado - 异步web框架,性能很好,生产环境下用Nginx代理

主要功能看web.py
核心io循环,高级功能看ioloop.py
模板看template.py
db看torndb.py(3.1已经挑出来做成单独库了)

get/post及json使用:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

#!/usr/bin/env python # -*- coding:utf-8 -*- import tornado.ioloop import tornado.web import json class MainHandler(tornado.web.RequestHandler): def get( self ): self .write( "Hello, World" ) # 访问: http://localhost:8888/story/sishen232 # 显示:U get story id is sishen232 class StoryHandler(tornado.web.RequestHandler): def get( self , story_id): self .write( "U get story id is " + story_id) class AddHandler(tornado.web.RequestHandler): # 这里可以用get的form信息,也可以直接用curl来post json数据 def post( self ): raw_data = self .request.body print "raw:" , raw_data res = json.loads(raw_data) s = res[ "num1" ] + res[ "num2" ] self .write(json.dumps({ "sum" :s})) application = tornado.web.Application([ (r "/" , MainHandler), (r "/story/(sishen[0-9]+)" , StoryHandler), # 正则url映射,方便get (r "/add" , AddHandler), ]) if __name__ = = "__main__" : application.listen( 8888 ) tornado.ioloop.IOLoop.instance().start()

测试:

?

1	flyking@wf - vm - slave1:~$ curl - d '{"num1": 3, "num2": 5}' "http://localhost:8888/add"

结果:

?

1	{ "sum" : 8 }
