    服务是直接跑的flask。直接 app.run() 跑的。
    特别好奇的是第一条为什么返回200了。

    125.46.40.22 - - [09/Nov/2014 06:04:52] "HEAD http://www.baidu.com/ HTTP/1.1" 200 -
    125.46.53.167 - - [09/Nov/2014 06:40:25] "CONNECT www.google.com:443 HTTP/1.0" 404 -
    112.90.55.152 - - [09/Nov/2014 12:23:57] code 400, message Bad request syntax ('D!@\x00')
    112.90.55.152 - - [09/Nov/2014 12:23:57] "D!@ " 400 -
    1.161.31.103 - - [10/Nov/2014 00:39:49] "CONNECT mx0.mail2000.com.tw:25 HTTP/1.0" 404 -

    HEAD 是标准请求，和GET一样，但是不返回BODY。
    CONNECT是代理请求，通过HTTP代理链接HTTPS网站主要通过这个方式。
    这些是检测你的服务器是不是一个开放代理。

    @sivacohan 这个200是你的服务器响应的，不是应该看看你的代码吗……

    同问。 手上一个服务器的log里也有很多类似 GET http://www.baidu.com 的请求 不知道是想干嘛。
