Python 认证后，它'；s没有重定向到django中的下一页

身份验证后，我无法重定向到Django中的下一页。我已经在views.py文件中定义了下一页，并调用了该值，但在URL中重定向到登录页，URL如下：

如果没有@login\u，则要求其正常工作

将用户名和密码重定向到

但我想：

（和显示主页）

请帮忙

您有一些不同的事情正在影响它

您的

url.py

文件需要清理。因为您已经定义了自己的登录/注销方法，所以不需要使用

django.contrib.auth.views

中的方法。因此，您的基本

url.py

文件应该如下所示：

from django.conf.urls import url
from django.contrib import admin
import login.views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^home/', include('login.urls')
    url(r'^$', login.views.login)
    url(r'^logout/$', login.views.logout)
]

您的

登录/url.py

文件可以保持不变。现在，我们将登录/注销指向您的视图，而不是

django.contrib.auth.views

您有

设置。LOGIN\u URL

设置为

LOGIN/

，但您的

URL.py

文件将

/

指向登录功能。对于这个答案，我正在更改

设置。登录到
/
以匹配您的URL文件

您的
login/views.py
文件只需要做一些更改，因为我们已经更新了
url.py
文件

我清理了一些不必要的导入语句，并从
@login\u required
中删除了
redirect\u field\u name='next'
，因为
'next'
是默认值

我们需要检查
POST
和
GET
对象以获取
next
参数

最大的变化是在我们验证用户并验证他们是否处于活动状态之后，而不是
返回HttpResponseRedirect（settings.LOGIN\u REDIRECT\u URL）
我们只需
返回HttpResponseRedirect（'/home'）
或将他们发送到我们从
POST
获取数据的
下一个
URL

from django.shortcuts import render
from django.contrib import auth
from django.contrib.auth.decorators import login_required
from django.http import HttpResponse, HttpResponseRedirect
from django.conf import settings

def login(request):
    next = request.POST.get('next', request.GET.get('next', ''))
    if request.method == "POST":
        username = request.POST.get('username')
        password = request.POST.get('password')
        user = auth.authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                login(request, user)
                if next:
                    return HttpResponseRedirect(next)
                return HttpResponseRedirect('/home')
            else:
                return HttpResponse('Inactive user')
        else:
            return HttpResponseRedirect(settings.LOGIN_URL)
    return render(request, "login.html")

def logout(request):
    auth.logout(request)
    # Redirect back to login page
    return HttpResponseRedirect(settings.LOGIN_URL)


@login_required
def home(request):
    return render(request, "home.html")

一旦你有了它，除非我还缺少什么，否则如果用户没有登录，
@login\u required
应该正确地重定向到你的登录页面。
首先，确保你更改了你的密钥，因为现在所有人都可以看到它……我不确定在没有看到你的项目的情况下是否可以帮助你。当我创建一个新项目时，我的回答对我来说很好。我知道你做了。正如我所说，它在一个新项目中对我有效。这说明您的实现中存在一些不正确或缺失的地方。
