当页面中form使用POST方式向后台提交时,报如下错误:

禁止访问 (403)

CSRF验证失败. 请求被中断.

Help

Reason given for failure:

​ CSRF token missing or incorrect.

In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django's CSRF mechanism has not been used correctly. For POST forms, you need to ensure:

  • Your browser is accepting cookies.

  • The view function passes a request to the template's render method.

  • In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL.

  • If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data.

  • The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.

    You're seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed.

    You can customize this page using the CSRF_FAILURE_VIEW setting.

在网上查找了很多资料,普遍采用的解决方法是:

  1. 检查settings.py中是否有下面的配置,如没有加上:

    MIDDLEWARE_CLASSES = (

    'django.middleware.common.CommonMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware', # 确认存在

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

    )

  2. html中的form添加模板标签{% csrf_token %}

    <form action="/saveBlog/" method="post">

    {% csrf_token %}

    ...

    </form>

  3. 针对views.py进行修改

    from django.shortcuts import render_to_response

    from django.template import RequestContext

    def some_blog(request):

    # ...

    return render_to_response('my_template.html',

    my_data_dictionary,

    context_instance=RequestContext(request))

    以上各步都基本照做了。其中针对视图的修改,因我的写法与网上不一样,我的是:

    def edit_blog(request):

    template = get_template('editBlog.html')

    moods = Mood.objects.all()

    html = template.render(locals())

    ``

    return HttpResponse(html)

    因为官方文档上说renderrender_to_responseshortcut,所以没有照网站资料上说的去改。于是错误总是无法解决。

几番挣扎之后,终于在Django出错页面中自己给出的解决办法中有一条:The view function passes a request to the template's rendermethod.(即:视图函数中传递 request 给模板的render方法)。

按这个访求修改后,终于解决问题了!!

def edit_blog(request):

template = get_template('editBlog.html')

moods = Mood.objects.all()

html = template.render(locals(), request) # 把request传递给template.render()

``

return HttpResponse(html)
