导入中间件app.middleware时导致错误：“无法导入名称get_host”

问题描述

我刚刚升级到Django 1.5，当我尝试访问一个页面时，我收到以下错误：

I've just upgraded to Django 1.5, and when I try and access a page, I get the following error:

ImproperlyConfigured: Error importing middleware app.middleware: "cannot import name get_host"

在shell中，我尝试类似的事情：

In the shell, I try a similar thing:

>>> from app import middleware
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File ".../middleware.py", line 2, in <module>
    from django.http import HttpResponseRedirect, HttpResponsePermanentRedirect, get_host
ImportError: cannot import name get_host

导入 get_host 失败。似乎这不被弃用，发生了什么？

It's failing on the import of get_host. It doesn't seem that this is deprecated, what's going on?

推荐答案

在Django 1.5 django中。 http.get_host（）替换为 request.get_host（）。请参阅 HttpRequest 对象。

In Django 1.5 django.http.get_host() is replaced with request.get_host(). See the methods on HttpRequest object here.
