从iCloud获取CalDAV事件将返回"403 Forbidden"

Question

我正在使用SimpleCalDAV客户端使用PHP从iCloud(Apple)获取日历事件.在Apple引入特定于应用程序的密码之前,这个客户端运行良好 从那时起,对于某些用户帐户,我总是得到"403 Forbidden"结果:

连接到iCloud服务器:

我觉得奇怪的是我可以连接到服务器(登录),我得到200响应,这意味着我能够登录到iCloud.它似乎是一个用户帐户特定的问题.它适用于我的Apple帐户,但不适用于我的朋友.这可能是什么问题？

任何提示都受到高度赞赏.

Answer 1

根据这个：

HTTP 状态代码 403 响应是 Web 服务器被配置为拒绝客户端访问所请求资源的结果。

我预计您的朋友可能不允许您访问他的私人日历。

他必须与您共享他的日历（邀请您查看日历），然后您才能使用您的帐户访问日历数据。

并且根据此文档，日历无法同时设置为“公共”。

最后，您还可以仔细检查 403 错误是否与您朋友这边的问题（Too Many iCloud Accounts）无关

另请注意，如果您想通过 iCloud 帐户使用第三方应用程序，则必须启用双因素身份验证并为每个应用程序生成单独的密码。
