Django将非www转发到www的方法？

Question

In django I am wondering if there is a django-designed way to redirect http://www.example.com to http://example.com or the other way around http://example.com > http://www.example.com .

Usually one would use htaccess for this, but it should be a simple issue so I was wondering if there is a design-method to handle this?

Answer 1

To do that, you need to add PREPEND_WWW setting to your settings.py file.

PREPEND_WWW = True  # Default value is False

Django will then prepend the “www.” subdomain to URLs that don't have it. So, URLs that lack a leading “www.” will be redirected to the same URL with a leading “www.”

Note: This will work only if CommonMiddleware is present in the MIDDLEWARE_CLASSES settings.

MIDDLEWARE_CLASSES = (
    ...
    'django.middleware.common.CommonMiddleware', # must be there in middlewares
   ...
)

Answer 2

You can do it only one-way in django, with PREPEND_WWW :

Whether to prepend the “www.” subdomain to URLs that don't have it. This is only used if CommonMiddleware is installed (see Middleware). See also APPEND_SLASH.

However, you server should be configured correctly to recognize the URL and correctly route the request. Otherwise you'll have issues (infinite redirects, for example).
