Question

我正在使用Coroutine功能构建Tornado Web应用程序。为了测试应用程序的性能，我使用了Siege。但是，使用Siege调用URL时发生了503错误。顺便说一下，我的应用程序在Raspberry Pi上运行。

我的应用的片段：

import os
import tornado.web
import tornado.gen
import tornado.ioloop
import tornado.options
import tornado.httpclient

tornado.options.define("port", default=8888, help="message...", type=int)

url='http://..../'

class Async(tornado.web.RequestHandler):
    @tornado.gen.coroutine
    def get(self):
        client = tornado.httpclient.AsyncHTTPClient()
        response = yield client.fetch(url)
        self.write('%r' % response.body)


def main():
    # Command line
    tornado.options.parse_command_line()
    app = tornado.web.Application(
            [
                (r'/async', Async)
            ],
            debug=True,
            autoreload=True
        )
    app.listen(tornado.options.options.port)
    tornado.ioloop.IOLoop.current().start()

if __name__ == "__main__":
    main()

命令：

siege 192.168.1.x:8888/async -c 5 -r 5

错误信息：

那么，我是否省略了一些设置？

如果你能指出我的应用程序出了什么问题，我将非常感激。非常感谢你。

我将网址更改为http://www.google.com，并且没有发生503错误。我还在Mac上测试了我的应用程序，它运行良好。因此，我认为这些错误是由于我获取数据的原因所致。

无论如何，非常感谢你，SDilmac。
