CSRF 验证失败 - 请求中止

Question

我在 Django 中遇到 CSRF 失败并且没有任何文章有效。它说它用于我记得的帖子，它包含在表单中，但不包含在表单标签中。

settings.py

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

login.html

{% extends 'base.html' %}
{% block body_block %}

<h1>Login</h1>

<form id="login_form" method="post" action="{% url 'accounts:login' %}">
    {% csrf_token %}
    <div class="input-group input-group-md">
        <span class="input-group-addon">Username</span>
        <input type="text"class="form-control" placeholder="Username" aria-describedby="basic-addon2" name="username" value="" size="50" />
    </div>
    <br>
    <div class="input-group input-group-md">
        <span class="input-group-addon">Password</span>
        <input class="form-control" placeholder="Password" aria-describedby="basic-addon2" type="password" name="password" value="" size="50" />
    </div>
     <br>
    <div class="input-group input-group-md">
        <input class="btn btn-default navbar-btn" type="submit" value="Submit" />
    </div>
</form>
<br /><br />
<a style="font-size:22px;" href="/accounts/register/">Need to make a new account?</a>


{% endblock %}

{% block buttons %}
{% endblock %}

views.py:

def user_login(request):
    context = RequestContext(request)
    if request.method == 'POST':
        form = LoginForm(request.POST)
        username = request.POST['username']
        password = request.POST['password']

        user = authenticate(username=username, password=password)

        if user:
            if user.is_active:
                login(request, user)
                return redirect('bookmarks:silo')
            else:
                return HttpResponse("Your Sitename account is disabled.")

        else:
            return render_to_response('accounts/login.html', locals(), context)
    else:

        template_name = 'accounts/login.html'
        return render_to_response('accounts/login.html', locals(), context)

为什么这个 csrf 令牌不起作用？

您需要像这样使用带有参数 context_instance 的 RequestContext :

def user_login(request):
    context = RequestContext(request)
    if request.method == 'POST':
        form = LoginForm(request.POST)
        username = request.POST['username']
        password = request.POST['password']

        user = authenticate(username=username, password=password)

        if user:
            if user.is_active:
                login(request, user)
                return redirect('bookmarks:silo')
            else:
                return HttpResponse("Your Sitename account is disabled.")

        else:
            return render_to_response('accounts/login.html', context_instance = context, locals(), )
    else:

        template_name = 'accounts/login.html'
        return render_to_response('accounts/login.html', context_instance = context, locals(), context)

还有一件事，context_instance 自 Django 1.8 以来已弃用。你可以只使用 :

 return render(request,'accounts/login.html', locals())
