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
requestto the template’srendermethod. -
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 usecsrf_protecton any views that use thecsrf_tokentemplate 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：
- 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',
) - html中的form添加模板标签{% csrf_token %}
<form action="/saveBlog/" method="post"></form>
{% csrf_token %}
... - 针对views.py进行修改
from django.shortcuts import render_to_response
from django.template import RequestContextdef 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())<br></code> return HttpResponse(html)<code>因为官方文档上说</code>render<code>是</code>render_to_response<code>的</code>shortcut，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 render method.（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()<br></code> return HttpResponse(html)
