AWS amplify add auth：如何在执行 amplify cli 后添加重定向登录 URI

Question

背景：我正在按照 AWS 教程使用 Amplify 创建 iOS 应用程序。步骤之一是使用“amplify add auth”并指定“重定向签名 URI”。由于某种原因，CLI 没有提示我输入 URL。“amplify update auth”不提供指定重定向 URL 的选项。

问题：执行“amplify add auth”命令后，如何将重定向 URL 添加到项目中？

我不知道你遇到什么问题，但你可以使用

amplify update auth

如果你试试：

amplify add auth

它会给你一个错误：

Auth 已添加到该项目中。要更新，请运行 amplify update auth。

使用 amplify update auth，系统会要求您提供 URI。
