Question

你好。我尝试通过login_required将用户重定向到他登录之前想要的页面，但是页面没有重定向！我已经搜索了很多，但是什么也没找到。这是我的login_required的主要代码：我将它们归纳为相关主题。如果需要添加其他内容，请告诉我。谢谢你。

查看：

from django.contrib.auth.decorators import login_required

def user_login(request):
    next_url = request.GET.get('next')
    print(next_url)
    if request.method == 'POST':
        form = UserLoginForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = authenticate(request, username=cd['username'], password=cd['password'])
            if user is not None:
                login(request, user)
                messages.success(request, 'Login Successful', extra_tags='success')
                if next_url:
                    return redirect(next_url)
                return redirect('post:all_posts')
            else:
                messages.error(request, 'Wrong Username Or Password', extra_tags='warning')
    else:
        form = UserLoginForm()
    return render(request, 'account/login.html', {'form': form})

@login_required
def dashboard(request, user_id):
    users = get_object_or_404(User, id=user_id)
    posts = Post.objects.filter(user=users)
    context = {'user': users, 'posts': posts}
    return render(request, 'account/dashboard.html', context=context)

登录视图：

{% extends 'base.html' %}

{% block content %}
    <form action="." method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Login" class="btn btn-primary">

{% endblock content %}

Answer 1

如您所见，GET请求中存在下一个查询，但是在提交表单时，URL查询没有被传递。您可以在与POST请求相对应的图像中看到它。您可能需要在登录表单中添加下一个URL，然后从POST数据中访问下一个URL。

在登录表单中添加隐藏字段

{% extends 'base.html' %} 
{% block content %} 
<form action="." method="post"> 
    {% csrf_token %} 
    {{ form.as_p }} 
    <input type="hidden" name="next" value="{{ request.GET.next }}" />
    <input type="submit" value="Login" class="btn btn-primary"> 
</form> 
{% endblock content %}

{p> {{ request.GET.next }}可被settings.TEMPLATES中的请求模板上下文处理器访问

然后在您的user_login中访问request.POST的下一个网址

def user_login(request): 
    if request.method == 'POST':
        next_url = request.POST.get('next')
        # code

Answer 2

可能对您有用。

def signin(request):
    if request.method == "POST":
        user_login_form = UserLoginForm(request.POST)
        email = request.POST['email']
        password = request.POST['password']
        user = authenticate(request, email=email, password=password)
        if user and user.is_active:
            login(request, user)
            try:
                if request.GET['next']:
                    return redirect(request.GET['next'])
            except Exception as e:
                return redirect('home')
        else:
            messages.error(request, "Please Enter Correct Credential")
            return render(request, 'signin.html', context={'form': user_login_form})
    else:
        user_login_form = UserLoginForm()
        return render(request, 'signin.html', context={'form': user_login_form})

login_required Django重定向下一步不起作用
