編輯:閱讀您的服務(wù)器日志。服務(wù)器可能會準(zhǔn)確地告訴您錯誤是什么。確保啟用調(diào)試。
沒有充分理由,403 錯誤并不是真正從服務(wù)器發(fā)出的——而且這個原因通常特定于您的應(yīng)用程序。403 通常是權(quán)限問題:我們知道你是誰,但你無權(quán)做你想做的事。
可能存在(或缺失)標(biāo)頭阻止請求進行任何更改(在您的情況下為 POST 請求)。例如,您的服務(wù)器可能正在設(shè)置 cookie 以防止 CSRF 攻擊。很多時候服務(wù)器不會驗證 GET 請求上的令牌,這可以解釋為什么 GET 請求適用于您的情況但不適用于 POST 請求。
如果你可以搜索你的服務(wù)器代碼,我愿意有這樣的偽代碼:
if (requestIsMissingCSRFToken()) { throw new Error(STATUS.FORBIDDEN) }

我只是有同樣的問題。非常感謝您發(fā)布此信息。我還在使用 Django 后端開發(fā) Chrome 擴展。
對我來說,從“DEFAULT_AUTHENTICATION_CLASSES”中刪除“rest_framework.authentication.SessionAuthentication”就可以了,但我保留了“oauth2_provider.contrib.rest_framework.OAuth2Authentication”。
根據(jù)這篇中篇文章, “rest_framework.authenication.SessionAuthentication”僅在您想保留可瀏覽的 API 時才需要。我啟用了 CSRF 和 CORS。所以我認(rèn)為我的設(shè)置非常安全。
下面是我的 settings.py 文件。

問題出在 Django REST 框架中。顯然它默認(rèn)啟用了一些身份驗證類。禁用/將它們設(shè)置為空數(shù)組settings.py將擺脫煩人的“403 Forbidden”錯誤。
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': [
]
}
編輯:我不知道這有多安全,但至少它有效。
