ios - 开发 Carddav/Caldav 服务器。同步后，事件在 iOS 客户端消失

菜鸟教程小白 · 发表于 2022-12-13 12:38:44

我目前正在开发一个 carddav/caldav 服务器。我已经可以在 windows/windows phone/android 上与很多客户端进行通信。现在我尝试与 iOS 同步。地址簿同步工作正常，但日历应用程序的行为很奇怪。它同步所有日历和约会并正确显示它们。它甚至将事件的参与者链接到地址簿中的联系人。但是一旦同步完成，日历和约会就会完全消失。有人有提示吗？

我的测试设备是装有 iOS 8.3 (12F69) 的 iPad 2。

这里是交流。我忽略了没有授权 header 的请求。我还必须编辑主机名，但在所有请求中都是相同的。

iOS 询问的很多属性我都没有回答。但由于所有约会都在短时间内正确显示，因此不需要这些。还有很多不是 caldav 规范的一部分(但仍然放在同一个 xmlns 中？)。

在此之后，还有 4 个 REPORT 请求来获取所有约会。之后，在主机的根目录中有一个 propfind 请求，由于 30.000 个字符的限制，我无法发布该请求。我无法回答这个请求，因为它没有到达我的 servlet。

感谢您的帮助。

Best Answer-推荐答案

今天，我终于可以修复错误了。在第一个请求中，ios 要求提供 principal-URL，我用 principal-url 回答。此标记名的最后一部分必须用大写字母书写，才能被 iOS 识别。它使用 URL 在同步后向委托(delegate)人发出一个(在我看来毫无意义的)请求。

关于ios - 开发 Carddav/Caldav 服务器。同步后，事件在 iOS 客户端消失，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34269944/
