编辑:阅读您的服务器日志。服务器可能会准确地告诉您错误是什么。确保启用调试。
没有充分理由,403 错误并不是真正从服务器发出的——而且这个原因通常特定于您的应用程序。403 通常是权限问题:我们知道你是谁,但你无权做你想做的事。
可能存在(或缺失)标头阻止请求进行任何更改(在您的情况下为 POST 请求)。例如,您的服务器可能正在设置 cookie 以防止 CSRF 攻击。很多时候服务器不会验证 GET 请求上的令牌,这可以解释为什么 GET 请求适用于您的情况但不适用于 POST 请求。
如果你可以搜索你的服务器代码,我愿意有这样的伪代码:
if (requestIsMissingCSRFToken()) { throw new Error(STATUS.FORBIDDEN) }

我只是有同样的问题。非常感谢您发布此信息。我还在使用 Django 后端开发 Chrome 扩展。
对我来说,从“DEFAULT_AUTHENTICATION_CLASSES”中删除“rest_framework.authentication.SessionAuthentication”就可以了,但我保留了“oauth2_provider.contrib.rest_framework.OAuth2Authentication”。
根据这篇中篇文章, “rest_framework.authenication.SessionAuthentication”仅在您想保留可浏览的 API 时才需要。我启用了 CSRF 和 CORS。所以我认为我的设置非常安全。
下面是我的 settings.py 文件。

问题出在 Django REST 框架中。显然它默认启用了一些身份验证类。禁用/将它们设置为空数组settings.py将摆脱烦人的“403 Forbidden”错误。
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': [
]
}
编辑:我不知道这有多安全,但至少它有效。
