Django-从网址中删除www [英] Django - remove www from URLs
问题描述
我已将其添加到我的 .htacces ：
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]
，但随后尝试访问 www.example.com ，将我重定向到：
but then trying to reach www.example.com redirects me to:
http://example.com/example/wsgi.py/
因为我有 WSGIScriptAlias /home/www/example.com/example/wsgi.py 指令放在我的 httpd.conf 中，我当然会收到404错误。
because i have WSGIScriptAlias / home/www/example.com/example/wsgi.py directive in my httpd.conf and of course i get 404 error.
最终，我设法通过在我的 urls.py 修复 $ c>：
Eventually, i've managed to fix this by adding next line in my urls.py:
url（r'^ example / wsgi.py / $'，index），（因此它会重定向到首页）
url(r'^example/wsgi.py/$', index), (so it redirects to home page)
但我不太确定这是正确的方法（因为当我尝试达到 www.example.com ，然后又更改为 example。 com ）
but i'm not quite sure that this is the right way to do it (because when i try to reach example.com i see that web browser changes address quickly to www.example.com and then again to example.com)
如果有人会问，是的，我看过这，但这也无济于事，因为浏览器遇到了URL递归问题（example.com/example.com/example.com/example.com /example.com ...）
If anyone would ask, yes i've seen this but this didn't help me either, because browser gets url recursive problem (example.com/example.com/example.com/example.com/example.com...)
编辑：文件夹结构
此是我的文件夹结构：
\mysite\
静态\
媒体\
。 htaccess
manage.py
mysite\
模板
templatetags
tinymce
静态
urls.py
settigs.py
views.py
wsgi.py
模型。 py
form.py
__init __。py
推荐答案
我找到了使用中间件和使用Apache mod_rewrite config可以更轻松地完成无www重定向。
I find it much simpler to accomplish no-www redirects with middleware that with with Apache mod_rewrite config.
您链接到的中间件看起来很有效。我猜你的问题来自Apache配置-确保删除所有mod_rewrite命令（ Rewrite * 东西），然后重新启动apache服务器（参考 Apache文档，但请检查您的操作系统，可能是特定的。）
The middleware that you linked to looks like it does the trick. I'm guessing your problems came from Apache config - make sure you remove all mod_rewrite commands (Rewrite* stuff) and then restart the apache server (ref. Apache docs but check for your OS, might be specific).
您应该做的另一项调整是：确保不重定向任何POST请求，因为这可能会导致数据丢失（切线ref：为什么HTTP不具有POST重定向？）。
There is only one additional tweak that you should to: make sure you don't redirect any POST requests, because that might result in lost data (tangent ref: Why doesn't HTTP have POST redirect?).
无论如何，这就是我使用的方式，对我来说效果很好：
Anyways, this is what I use, worked quite well for me:
from django.http import HttpResponseRedirect
class NoWWWRedirectMiddleware(object):
def process_request(self, request):
if request.method == 'GET': # if wanna be a prefect REST citizen, consider HEAD and OPTIONS here as well
host = request.get_host()
if host.lower().find('www.') == 0:
no_www_host = host[4:]
url = request.build_absolute_uri().replace(host, no_www_host, 1)
return HttpResponseRedirect(url)
要使用它，请将文件放在某个位置，也许是 mysite / mysite / middleware.py 。
然后确保它在您的 settings.py 中运行：
To use it, put in a file somewhere, maybe mysite/mysite/middleware.py.
Then make sure it's run, in your settings.py:
MIDDLEWARE_CLASSES = (
'mysite.middleware.NoWWWRedirectMiddleware',
# ... other middleware ...
如果您的 settings.py 中没有 MIDDLEWARE_CLASSES ，则复制默认值来自在Django文档中，但是让您正在查看正确版本的Django，1.7中有一些更改！
If there is no MIDDLEWARE_CLASSES in your settings.py then copy the defaults from here in the Django docs but make you're looking at the correct version of Django, there are some changes in 1.7!
