http头部和http_code状态码处理

@tornado.web.asynchronousdef post(self):"""Handle POST requests."""# Disable cachingself.set_header("Cache-Control","no-cache, must-revalidate")self.set_header("Expires","Mon, 26 Jul 2013 05:00:00 GMT")self.poll_start = time.time()action = self.get_argument("action")if action=="poll":self.poll()elif action=="message":self.process_incoming(self.get_argument("message"))else:self.set_status(400)self.finish()

获取所有输入数据,存储起来方便处理:

class BaseHandler(tornado.web.RequestHandler):def recvData(self):data = defaultdict(lambda : None)# 获得所以输入参数,并存在data中args = self.request.argumentsfor a in args:data[a] = self.get_argument(a)# 获取file类型参数data["files"] = self.request.files# 获取headersdata["headers"] = self.request.headersreturn data

通过正则匹配url返回json

from datetime import dateimport tornado.escape
import tornado.ioloop
import tornado.webclass VersionHandler(tornado.web.RequestHandler):def get(self):response = { 'version': '3.5.1','last_build':  date.today().isoformat() }self.write(response)class GetGameByIdHandler(tornado.web.RequestHandler):def get(self, _id):response = { 'id': int(_id),'name': 'Crazy Game','release_date': date.today().isoformat() }self.write(response)application = tornado.web.Application([(r"/getgamebyid/([0-9]+)", GetGameByIdHandler),(r"/version", VersionHandler)
])if __name__ == "__main__":application.listen(8888)tornado.ioloop.IOLoop.instance().start()

输入:  http://localhost:8888/version 
结果: {"last_build": "2013-10-22", "version": "3.5.1"}
