define('port', 7777)
MIDDLEWARES = ['plugins.slow_request.SlowRequestMiddleware', 'plugins.profile.ProfileMiddleware']
define("middlewares", default=MIDDLEWARES, help="middleware class list")


class With(TMiddlewareHandler):
    def get(self):
        import time
        time.sleep(4)
        return self.finish('Hello World!')


def run():
    application = tornado.web.Application([('/', With)])
    http_server = tornado.httpserver.HTTPServer(application, xheaders=True)
    http_server.listen(options.port, '0.0.0.0')
    tornado.ioloop.IOLoop.instance().start()

if __name__ == '__main__':
    run()

此处使用了自带的两个 middleware，一个用于查看请求的 profile 信息，一个用于在终端下记录超时的请求

$ python miminal.py

$ chrome http://localhost:7777/?profile=true

web:

console:

Plugins

自带了两个：

1. profile: 查看请求的内部函数耗时信息
2. slow_request: 记录超时请求

自定义插件参考这两个即可
