Tornado框架使用uvloop事件循环

官方提供的写法

import asyncio

import uvloop
from tornado.platform.asyncio import AsyncIOMainLoop
import tornado.web
import tornado.ioloop
import tornado.options


class IndexHandler(tornado.web.RequestHandler):

    def get(self):
        """对应http的get请求方式"""
        self.write("Hello World!")


def run_server():
    tornado.options.parse_command_line()

    asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
    AsyncIOMainLoop().install()

    app = tornado.web.Application([
        (r"/", IndexHandler),
    ])
    app.listen(8000)
    asyncio.get_event_loop().run_forever()


if __name__ == '__main__':
    run_server()
