凭据对话框(Google 表单)已成功打开，但在我填写凭据后出现此错误。我按照 here 的说明进行操作.创建了一个 Firebase 项目，从 Google API 控制台启用了 Google Drive API(这就是我现在需要的)。

抛出异常的代码:

final GoogleSignIn _googleSignIn = GoogleSignIn(
  scopes: [
    'https://www.googleapis.com/auth/drive',
  ],
);

await _googleSignIn.signIn();

这是堆栈跟踪:

最佳答案

我刚才遇到了同样的问题。如果您在调试中运行并且您确实未注册了 SHA，则可能会发生这种情况。 Firebase 中的指纹。 我通过生成 debug.keystore 来解决它并将其注册到 Firebase 上的应用程序中。不要忘记下载新的google-services.json在那之后。 另见 this .

编辑 如果您无法在 Release模式下使用身份验证，请尝试以下操作:

-添加发布 key 的SHA证书指纹。

keytool -exportcert -list -v \ -alias <your-key-name> -keystore <path-to-production-keystore>

更多详情请参见 "get release certificate" 部分。 https://developers.google.com/android/guides/client-auth

如果您的身份验证仍然无效，可能是因为您从 Playstore 下载了该应用并启用了“Google Play 应用签名功能” 然后对于这种情况，去玩商店发布控制台，去发布管理下的应用签名。在那里，您将找到要在 Firebase 控制台中注册的 SHA 证书指纹。
