使用tornado创建一个Web应用的基础

import tornado.httpserver
import tornado.ioloop
import tornado.options  #从命令行中读取设置
import tornado.web

from tornado.options import define, options
define("port", default=8000, help="run on the given port", type=int)

# Tornado支持任何合法的HTTP请求（GET、POST、PUT、DELETE、HEAD、OPTIONS）
class IndexHandler(tornado.web.RequestHandler):
    def get(self):
        greeting = self.get_argument('greeting', 'hello')
        self.write(greeting + ', 佳全')

if __name__ == "__main__":
    tornado.options.parse_command_line()
    app = tornado.web.Application(handlers=[(r"/", IndexHandler)])
    http_server = tornado.httpserver.HTTPServer(app)
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()
