以下文档描述here，我使用隐式授权设置了帐户链接，并发现在使用浏览器/操作控制台以及 Android 版 Google Home 应用程序进行测试时效果良好。不幸的是，在该应用程序的 iPhone 版本上，用户身份验证大多数时候都会挂起。谷歌支持操作的反馈是，问题在于谷歌登录流程是在单独的浏览器选项卡（窗口）中实现的。在iPhone上，您无法在SfariViewController中打开2个窗口，因此它们正在重写第一页的地址，并且无法完成登录流程。这是已知问题，他们不打算改变这一点。解决方案是在一个浏览器窗口中实现所有登录流程。我不清楚如何做到这一点，并且正在寻找有人分享您设置的授权 URL 背后的代码，这些代码在 iPhone 上一致工作。以下是我正在使用的核心：

@dana 你尝试过添加元标记吗？
