Django Rest Framework - 删除问题 - 未找到 CSRF

Question

我正在将 Django Rest Framework 与 CSRF 结合使用。POST和PUT方法按预期工作，但DELETE给出错误 403 - 以下消息“{"detail":"CSRF Failed: CSRF token missing or incorrect."}.

看来前端应用程序（Angular）正在执行正确的POST请求PUT。我没有遇到任何与CSRFNor相关的问题CORS。

例子：

然后，当我执行“PUT”请求时，它的执行不会出现任何问题：

放置请求：

您可以看到 DELETE 和 PUT 中使用了相同的令牌，但由于某些原因，只有 PUT 按预期工作。

对于 POST 来说它也工作正常。再说一遍，我只遇到删除问题。

非常感谢您的帮助。

我期望 POST、PUT 和 DELETE 的工作方式与正确使用 CSRF 的方式相同。
