推送异常：PushSharp Exception : 提供给包的凭据未被识别。

Question

在使用Pushsharp发送IOS推送通知时，我遇到了以下异常。我查阅了许多文章，但并没有清晰的思路来解决这个问题。安卓设备运行良好，唯一的问题就是在IOS上。

异常信息：

Answer 1

我已经找到了问题所在。我撤销了证书并重新生成了它，这次只导出了Keychain访问中的私钥（不包括证书），将其导出为.p12文件并使用了新文件，结果成功了。由于某种原因，当证书和私钥同时存在于文件中时，PushSharp无法很好地处理.p12文件。

Answer 2

当使用Windows证书存储（在我看来是在生产服务器上管理证书的最简单方法）时，请确保在私钥上设置正确的权限。

经过 4 小时的测试：

将 .p12 转换为 .pem，它就可以在 IIS 有限用户中使用了....
