Root Cause

AJAX request does not include CSRF token in headers or cookie is missing.

generic

中文

AJAX 请求未在标头中包含 CSRF 令牌，或 cookie 缺失。

Workarounds

  1. 95% success 
    Ensure CSRF cookie is set by using {% csrf_token %} in template, then include token in AJAX: headers: {'X-CSRFToken': getCookie('csrftoken')}
  2. 90% success 
    Use Django's ensure_csrf_cookie decorator on the view that returns the page.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Adding @csrf_exempt to view bypasses security, not recommended.

  2. 70% fail

    Hardcoding CSRF token in JavaScript doesn't work as it changes per session.
