升级到Django 1.11后，append_slash不再起作用 [英] After upgrade to Django 1.11 append_slash no longer works

问题描述

在Django 1.9（和Python 3.4）中，默认的APPEND_SLASH可以正常工作，即我可以输入'localhost：8000 / ideatree / videos'
并添加斜杠。

In Django 1.9 (and Python 3.4) the default of APPEND_SLASH worked correctly, i.e. I could enter 'localhost:8000/ideatree/videos' and the trailing slash would be added.

升级到Django 1.11（和Python 3.6）后，APPEND_SLASH不再起作用。

After an upgrade to Django 1.11 (and Python 3.6), APPEND_SLASH is no longer working.

我一直在寻找弃用通知，但是到目前为止，没有发现任何似乎适用的内容。 （旁边的问题：您如何像以前的版本一样重新打开大声弃用警告？）

I've looked for deprecation notices but so far found nothing that seems to apply. (side question: how do you turn 'loud deprecation warnings' back on, as they were in previous versions?)

这是我的主要urls.py：

Here is my main urls.py:

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [   url(r'^(?i)ideatree/', include('ideatree.urls'),
 name='home'),
]

以及包含的app_space中的urls.py：

and the urls.py from the included app_space:

from django.conf.urls import url
from . import views

app_name = 'ideatree'
urlpatterns = [
   url(r'^$', views.index,name='index'),
   url(r'^(?i)features/$', views.features, name='features'),
   url(r'^(?i)videos/$', views.videos, name='videos')
]

除了Django 1.9中，这两个url.py文件均未更改

Both these url.py files are unchanged except that in Django 1.9 I had

from django.conf.urls import patterns, include, url

在主urls.py中，但是现在不建议使用模式并发出警告。

in the main urls.py, but 'patterns' is now deprecated and throws a warning.

和以前一样，我没有根据其默认值True在settings.py中设置APPEND_SLASH，尽管我尝试将其默认值显式设置为True。

As before, I do not have APPEND_SLASH set in settings.py, relying on its default value of True, though I tried explicitly setting it to True with the same result.

这是我的中间件：

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

这里是错误：

Page not found (404)
Request Method: GET
Request URL:    http://localhost:8000/ideatree/videos

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^(?i)ideatree/ ^$ [name='index']
^(?i)ideatree/ ^(?i)features/$ [name='features']
^(?i)ideatree/ videos/$ [name='videos']

我还尝试清除浏览器缓存，并使用其他

I also tried clearing the browser cache, and using a different browser in case the cache still didn't get cleared.

登录到DEBUG级别或INFO级别的文件不会显示任何内容，一个空文件（警告：我的l ogging设置未经测试）。

Logging to file at level DEBUG or level INFO shows nothing, an empty file (warning: my logging setup is untested).

我必须忽略某些东西。

推荐答案

Django在Django 1.10中引入了新的中间件。如果您使用的是 MIDDLEWARE 设置= nofollow noreferrer>新型中间件和 MIDDLEWARE_CLASSES （如果您使用的是旧式中间件。

Django introduced new middleware in Django 1.10. You should use the MIDDLEWARE setting if you are using new-style middleware, and MIDDLEWARE_CLASSES if you are using old-style middleware.

如果您使用的是Django 1.10或1.11，那么仍然支持旧的 MIDDLEWARE_CLASSES 设置，因此Django应该继续使用附加的斜杠进行重定向。

If you are using Django 1.10 or 1.11, then the old MIDDLEWARE_CLASSES setting is still supported, so Django should continue to redirect with the appended slash.

但是，升级到Django 2.0后， MIDDLEWARE_CLASSES 设置将被忽略，您必须切换到 MIDDLEWARE 。

However, once you upgrade to Django 2.0, the MIDDLEWARE_CLASSES setting is ignored and you must switch over to MIDDLEWARE.

切换到 MIDDLEWARE 时，应删除 SessionAuthenticationMiddleware ，因为它在1.10和1.11中无效，在Django 2.0中已完全删除。

When you switch over to MIDDLEWARE, you should remove SessionAuthenticationMiddleware since it has no effect in 1.10 and 1.11, and is removed completely in Django 2.0.
