MSAL Android：获取令牌时缺少类型为 {0} 的必需令牌

Question

我正在将MSAL 2.2.1集成到 Android 应用程序中。

1. 我已在 Azure b2c 门户中注册了该应用程序。
2. 生成签名并将其添加到 Azure b2c 门户。
3. 尝试获取令牌时获得登录页面。
4. 成功登录后，MSAL 重定向到我们的应用程序。但不是 onSuccess 而是 onError 并带有以下堆栈跟踪。

onError：缺少类型所需的令牌：{0}

我的请求代码如下所示：

application.acquireToken(requireActivity(),arrayOf("openid", "offline_access"),object : AuthenticationCallback {

我已在 Azure b2c 门户中授予这些权限。

但仍然无法获取token。有人可以帮忙解决这个问题吗？提前致谢。

Answer 1

我通过使用我的 client-id 作为 Scope 类型解决了这个问题：

public static List<String> getScopes() {
    return Arrays.asList(
            "your-client-id-here");
}

Answer 2

这是由于传递了无效的作用域类型或省略了所需的作用域值。就我而言，身份验证响应包含 and id_token，refresh_token但不包含access_token.

库提供的错误消息没有帮助，我在这里提交了一个问题： https: //github.com/AzureAD/microsoft-authentication-library-common-for-android/issues/1674
