Django1.3 CSRF verification failed. Request aborted.

Forbidden (403)

CSRF verification failed. Request aborted.

今天遇到这个问题，在https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ref-contrib-csrf 上解决办法：

1. Add the middleware 'django.middleware.csrf.CsrfViewMiddleware' to your list of middleware classes, MIDDLEWARE_CLASSES. (It should come before any view middleware that assume that CSRF attacks have been dealt with.)

   Alternatively, you can use the decorator csrf_protect() on particular views you want to protect (see below).

2. In any template that uses a POST form, use the csrf_token tag inside the <form> element if the form is for an internal URL, e.g.:

   <form action="." method="post">{% csrf_token %}

   This should not be done for POST forms that target external URLs, since that would cause the CSRF token to be leaked, leading to a vulnerability.

发现setting.py文件里已经有'django.middleware.csrf.CsrfViewMiddleware'，

然后在HTML文件的<FORM>标签后加上{% csrf_token %}问题依然没有解决。

最后在网上找到答案，说要在MIDDLEWARE_CLASSES.里加上'django.middleware.csrf.CsrfResponseMiddleware'。

继续测试，问题解决，把HTML文件的<FORM>标签后去掉{% csrf_token %}不再报错。注释掉MIDDLEWARE_CLASSES 里的'django.middleware.csrf.CsrfViewMiddleware'也不报错。
