tornado 多个 url

[xlzd]

请问各位, 服务器端用的tornado, 假如几个domain都指向了同一个地址, 应该怎么得到被访问的域名呢?

你想是问Tornado怎么实现Vhost吧,用Nginx就行了呀,不同的Hostname转发给不同的Tornado实例.

如果前面有nginx的话，设置

proxy_set_header Host $host;

然后tornado中：

self.request.host可以取的到

"""
We support virtual hosts with the `add_handlers` method, which takes in
a host regular expression as the first argument::

application.add_handlers(r"www\.myhost\.com", [
(r"/article/([0-9]+)", ArticleHandler),
])
