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'srender
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 usecsrf_protect
on any views that use thecsrf_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.
常见出现问题的情况是:在提交form表单的时候;没有在form表单中添加{% csrf_token %}
