Django CSRF cookie未正确设置

Question

更新7-18:

这是我的代理服务器的nginx配置:

server {
    listen 80;
    server_name blah.com; # the blah is intentional

    access_log /home/cheng/logs/access.log;     
    error_log /home/cheng/logs/error.log;       

    location / {
        proxy_pass http://127.0.0.1:8001;         
    }

    location /static {
        alias /home/cheng/diandi/staticfiles;  
    }

    location /images {
        alias /home/cheng/diandi/images;
    }

    client_max_body_size 10M;
}

这是nginx.conf:

        worker_connections 768;
        # multi_accept on;

        # Compression level (1-9).

        # Tell proxies to cache both the gzipped and regular version of a resource

        # Avoids the issue where a non-gzip capable client (which is extremely rare

        gzip_vary          on;

        # Compress all output labeled with one of the following MIME-types.

更新7-15:

将代码复制到linux机器时,我只是更换了原始的源代码文件,但没有删除旧的.pyc文件,我认为这些文件不会造成麻烦吗？

---

这是视图代码:

from django.contrib.auth import authenticate, login
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.shortcuts import render

def login_view(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(username=username, password=password)
        next_url = request.POST['next']
        if user is not None:
            if user.is_active:
                login(request, user)
                if next_url:
                    return HttpResponseRedirect(next_url)
                return HttpResponseRedirect(reverse('diandi:list'))
        else:
            form = {'errors': True}
            return render(request, 'registration/login.html', {'form': form})

    else:
        form = {'errors': False}
        return render(request, 'registration/login.html', {'form': form})

我CSRF cookie not set从Django 得到了一个错误,但这不是因为我忘了{% csrf_token %}在我的模板中包含它.

这是我观察到的:

访问登录页面#1尝试

在里面Request Header,cookie价值是:

csrftoken=yNG8ZmSI4tr2xTLoE9bys8JbSuu9SD34;

在模板中:

<input type="hidden" name="csrfmiddlewaretoken" value="9CVlFSxOo0xiYykIxRmvbWyN5iEUHnPB">

在我安装在chrome上的cookie插件中,实际的csrf cookie值设置为:

9CVlFSxOo0xiYykIxRmvbWyN5iEUHnPB

访问登录页面#2尝试:

在里面Request Header,cookie价值是:

csrftoken=9CVlFSxOo0xiYykIxRmvbWyN5iEUHnPB;

在模板中:

<input type="hidden" name="csrfmiddlewaretoken" value="Y534sU40S8iTubSVGjjh9KQl0FXesVsC">

在我安装在chrome上的cookie插件中,实际的csrf cookie值设置为:

Y534sU40S8iTubSVGjjh9KQl0FXesVsC

模式

从上面的示例中可以看出,其中的cookie值Request Header与csrfmiddlewaretoken表单中的实际值和设置的实际cookie值不同.

当前请求的request header'scookie值与下一个cookie值匹配.

为了帮助调试,这里是我的`settings.py的一部分:

DJANGO_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',

    'django.contrib.staticfiles',

    'floppyforms',
    'multiselectfield',

LOCAL_APPS = (

INSTALLED_APPS = DJANGO_APPS + THIRD_PARTY_APPS + LOCAL_APPS

        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.media',

                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

我正在使用Django 1.9.5和python 2.7.10.

一个"解决方案"

我以前遇到过这个问题,我可以清除所有浏览器cookie,网站也能正常运行.但是这个问题最终会再次出现,所以我真的希望有人可以帮助我(我可能只是在某个地方犯了一个非常愚蠢的错误).

更新

最初,我认为我在覆盖django.contrib.auth.view页面时犯了一些错误,所以我编写了自己的登录页面处理程序,但仍然会导致问题.

这是我的登录模板的核心部分:

{% block content %}
...

                <form method="post" action="{% url 'login' %}">
                    {% csrf_token %}

                    <div class="form-group">
                        <label for="username">username</label>
                        <input type="text" class="form-control" id="id_username" name="username">
                    </div>
                    <div class="form-group">
                        <label for="password">password</label>
                        <input type="password" class="form-control" id="id_password" name="password">
                    </div>

                    <input type="submit" class="btn btn-default" value="login" />
                    <input type="hidden" id="next" name="next" value="" />
                </form>

...

{% endblock %}

在Linux机器上,我有一个nginx服务器设置作为反向代理,它将端口80上的请求定向到8001,并且我正在运行服务器./manage runserver localhost:8001这是我在设置方面可以想到的唯一区别.否则,所有源代码和设置文件都是相同的.

我开始删除cookie但不是全部删除,这是我在删除它之前看到的:

我删除了除了djdt和之外的所有cookie csrftoken,然后页面工作了.被删除的cookie是否会以某种方式超过某些限制,这会阻止列表中的csrftoken被设置？

以下是请求标头中上图中的cookie值:

Cookie:PSTM=1466561622; BIDUPSID=6D0DDB8084625F2CEB7B9D0F14F93391; BAIDUID=326150BF5A6DFC69B6CFEBD67CA7A18B:FG=1; BDSFRCVID=Fm8sJeC62leqR8bRqWS1u8KOKg9JUZOTH6ao6BQjXAcTew_mbPF_EG0PJOlQpYD-hEb5ogKK0mOTHvbP; H_BDCLCKID_SF=tJPqoCtKtCvbfP0k-tcH244HqxbXq-r8fT7Z0lOnMp05EnnjKl5M3qKOqJraJJ585Gbb5tOhaKj-VDO_e6u-e55LjaRh2PcM2TPXQ458K4__Hn7zep0aqJtpbt-qJjbOfmQBbfoDQCTDfho5b63JyTLqLq5nBT5Ka26WVpQEQM5c8hje-4bMXPkkQN3T-TJQL6RkKTCyyx3cDn3oyToVXp0njGoTqj-eJbA8_CtQbPoHHnvNKCTV-JDthlbLetJyaR3lWCnbWJ5TMCo1bJQCe-DwKJJgJRLOW2Oi0KTFQxccShPC-tP-Ll_qW-Q2LPQfXKjabpQ73l02VhcOhhQ2Wf3DM-oat4RMW20jWl7mWPQDVKcnK4-Xj533DHjP; BDUSS=5TNmRvZnh2eUFXZDA5WXI5UG1HaXYwbzItaWt3SW5adjE1Nn5XbUVoWHZuYXBYQVFBQUFBJCQAAAAAAAAAAAEAAAC0JtydAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAO8Qg1fvEINXSU; Hm_lvt_a7708f393bfa27123a1551fef4551f7a=1468229606; Hm_lpvt_a7708f393bfa27123a1551fef4551f7a=1468229739; BDRCVFR[feWj1Vr5u3D]=I67x6TjHwwYf0; BDRCVFR[dG2JNJb_ajR]=mk3SLVN4HKm; BDRCVFR[-pGxjrCMryR]=mk3SLVN4HKm; cflag=15%3A3; H_PS_PSSID=1424_20515_13289_20536_20416_19861_14994_11792; csrftoken=xUgSHybzHeIwusN0GvMgB1ATeRrPgcV1

由于网站现在运行,我所有的都是五个饼干,而不是像上图中的14个:

Answer 1

问题在于:您不能拥有一个cookie,其中哪个键包含字符'['或']'

我在@Todor 链接后发现了解决方案,然后我发现了这个SO帖子.基本上python 2.7.x中有一个错误,它不会在值中解析带有']'的cookie.该错误已在2.7.10中修复.

我认为只是确认这个问题会很好.所以我挖掘了所有的cookie并找到了一个具有以下键/值的cookie:

key: BDRCVFR[feWj1Vr5u3D]
val: I67x6TjHwwYf0

所以我在本地插入了以下cookie并提交给服务器:

key: test
val: BDRCVFR[feWj1Vr5u3D]

登录页面工作,这意味着2.7.10确实修复了错误.

但后来我意识到方括号实际上是键值而不是值,所以我做了以下测试:

key: [
val: I67x6TjHwwYf0

和

key:]
val: I67x6TjHwwYf0

这两个cookie都会破坏登录过程并显示django:

CSRF cookie not set

因此,它所依赖的django或python库无法正确解析名称中带方括号的cookie.如果有人知道我应该在哪里提交此bug,请告诉我(django或python).

我要感谢所有在OP中发表评论的人:@raphv,@ trinchet,@ Phipip,@ YPCrumble,@ PeterBrittain和@Todor.非常感谢你们和我一起调试!

这个错误在Django 1.10中得到修复,只需要等待发布

更新:2016年7月19日

作为这篇文章的结果,我向 Django 提交了一份错误报告.我们将看看它是否会在将来的版本中修复.
