 {{request.http referer}} ??

推荐答案

信息位于 META HttpRequest 的$ c> 属性，它是 HTTP_REFERER （sic）键，所以我相信您应该可以在模板中访问它：

That piece of information is in the META attribute of the HttpRequest, and it's the HTTP_REFERER (sic) key, so I believe you should be able to access it in the template as:

{{ request.META.HTTP_REFERER }}

在shell中工作：

>>> from django.template import *
>>> t = Template("{{ request.META.HTTP_REFERER }}")
>>> from django.http import HttpRequest
>>> req = HttpRequest()
>>> req.META
{}
>>> req.META['HTTP_REFERER'] = 'google.com'
>>> c = Context({'request': req})
>>> t.render(c)
u'google.com'
