CSRF verification failed. Request aborted

在django中利用comments功能，发生错误，错误信息如下：

Forbidden (403)

CSRF verification failed. Request aborted.

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 uses RequestContext for the template, instead of Context.
• 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.

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.

解决方法：

1.其实也没有什么解决方法，其实在错误信息里边已经说了，“The view function uses RequestContext for the template, instead of Context”

通常情况下，我们在view里边通常是这么做：

def archive(request,text_id):
    all_posts = TextBody.objects.all()
    posts = all_posts.filter(id=text_id)
    t= loader.get_template('content.html')
    c = Context({'posts':posts})
    return HttpResponse( t.render(c) )

务必将 Context修改为RequestContext,修改后为 c = RequestContext(request,{'posts':posts})

务必在文件头引入： from django.template import loader,Context,RequestContext

2.在Html模板中加入csrf标签： 

<table>
  <form action="{% comment_form_target %}" method="post">
    {% csrf_token %}
    {{ form }}
    <tr>
      <td colspan="2">
        <input type="submit" name="submit" value="Post">
        <input type="submit" name="preview" value="Preview">
      </td>
    </tr>
  </form>
