根据here所述的文档，我将帐户链接设置为隐式授权，并发现在使用浏览器/操作控制台进行测试时以及使用适用于Android的Google Home应用程序时效果很好。不幸的是，在应用程序的iphone版本中，用户auth大部分时间都会挂起。来自谷歌支持的操作的反馈是，问题是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上你不能在SfariViewController中打开2个窗口，因此他们正在重写第一页的地址而无法完成登录流程。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登录流程。我不清楚如何执行此操作，并且正在寻找某人在您设置的授权网址后面共享代码，这些代码在iphone上始终如一。以下是我正在使用的核心：

@dana您是否尝试过添加元标记？
<meta name="google-signin-ux_mode" content="redirect">
答案 1 :(得分：1)
在Google支持和帮助的帮助下工程，现在已经解决了：
<meta name="google-signin-ux_mode" content="redirect"> 以下是一个简单的代码基础，您可以使用该基础为Google帐户关联操作获取授权终结点的工作版本：
