这篇文章主要介绍了Tornado高并发处理方法实例代码，具有一定借鉴价值,需要的朋友可以参考下

本文主要分享的是一则关于Tornado 高并发处理方法的实例，具体如下：

									#!/bin/env python

									# -*- coding:utf-8 -*-

									import tornado.httpserver

									import tornado.ioloop

									import tornado.options

									import tornado.web

									import tornado.gen

									from tornado.concurrent import run_on_executor

									from concurrent.futures import ThreadPoolExecutor

									import time

									from tornado.options import define, options

									define("port", default=8000, help="run on the given port", type=int)

									class SleepHandler(tornado.web.RequestHandler):

									  executor = ThreadPoolExecutor(2)

									  @tornado.web.asynchronous

									  @tornado.gen.coroutine

									  def get(self):

									    # 假如你执行的异步会返回值被继续调用可以这样(只是为了演示),否则直接yield就行

									    res = yield self.sleep()

									    self.write("when i sleep %s s" % res)

									    self.finish()

									  @run_on_executor

									  def sleep(self):

									    time.sleep(5)

									    return 5

									class JustNowHandler(tornado.web.RequestHandler):

									  def get(self):

									    self.write("i hope just now see you")

									if __name__ == "__main__":

									  tornado.options.parse_command_line()

									  app = tornado.web.Application(handlers=[

									      (r"/sleep", SleepHandler), (r"/justnow", JustNowHandler)])

									  http_server = tornado.httpserver.HTTPServer(app)

									  http_server.listen(options.port)

									  tornado.ioloop.IOLoop.instance().start()
