在 iOS 上自动启动 Google Authenticator 应用

Question

是否有支持在 iOS 上启动 Google 身份验证器的方式？

我想让客户更轻松地打开应用程序并复制基于时间的代码，然后再将其粘贴回我的应用程序。

我凭经验发现这个（Swift）代码将启动应用程序：

UIApplication.sharedApplication().openURL(NSURL(string: "otpauth://")!)

...但我想知道是否有更好的支持方式。

具体来说，是否支持没有参数的 otpauth:// 协议来简单地启动应用程序？

Answer 1

查看该应用程序的 Git 存储库，他们似乎已经为 bot otpauth和totp注册了自定义 URL 方案

https://github.com/google/google-authenticator/blob/bd50d15c348a978c314d2b30e586fbc562096223/mobile/ios/OTPAuth-Info.plist#L42

和这里

https://github.com/google/google-authenticator/blob/bd50d15c348a978c314d2b30e586fbc562096223/mobile/ios/Classes/OTPAuthURL.h#L23

这是有关如何准确构建 url 的文档：

在您正确地形成它们并将您的应用程序和 Google Authenticator 应用程序安装在同一台设备上之后，您只需要进行测试。
