未解析的引用“googleIdToken”

  • 772

我正在尝试在 Kotlin Jetpack 中使用 Firebase 身份验证设置 Google 登录。不知何故，我无法获取 googleIdToken。

我尝试了很多方法，仍然无法解决。我尝试过其他方法，但它们都被弃用了。

Row(
    horizontalArrangement = Arrangement.Center
) {
    val context = LocalContext.current

    // Initialize Credential Manager
    val credentialManager = CredentialManager.create(context)

    // Configure Credential Request
    val request = GetCredentialRequest.Builder()
        .addCredentialOption(
            GetGoogleIdOption.Builder()
                .setServerClientId(context.getString(R.string.default_web_client_id))
                .build()
        )
        .build()

    // Google Sign-In Icon
    Icon(
        painter = painterResource(id = R.drawable.google_search_logo),
        contentDescription = "Google Icon",
        modifier = Modifier
            .size(LocalConfiguration.current.screenWidthDp.dp * 0.075f)
            .clickable {
                CoroutineScope(Dispatchers.IO).launch {
                    try {
                        val response = credentialManager.getCredential(context, request)
                        val googleIdToken = response.googleIdToken // Adjusted to retrieve the token
                        if (googleIdToken != null) {
                            val firebaseCredential = GoogleAuthProvider.getCredential(googleIdToken, null)
                            FirebaseAuth.getInstance().signInWithCredential(firebaseCredential)
                                .addOnCompleteListener { task ->
                                    if (task.isSuccessful) {
                                        Log.d("SignIn", "Sign-in successful!")
                                        // Perform navigation or update UI
                                    } else {
                                        Log.e("SignIn", "Sign-in failed: ${task.exception}")
                                    }
                                }
                        } else {
                            Log.e("SignIn", "Google ID token is null")
                        }
                    } catch (e: Exception) {
                        Log.e("SignIn", "Credential Manager failed", e)
                    }
                }
            },
        tint = Color.Unspecified
    )
}

    当您使用以下代码行时：

    val response = credentialManager.getCredential(context, request)

    请注意，“response”对象属于GetCredentialResponse类型。因此，正如您在该类内部看到的，不存在“googleIdToken”属性。但是，存在一个credential属性。因此，您可以读取此属性：

    val credential = response.credential

    按照文档中提到的执行必要的检查 ，然后立即获取GoogleIdTokenCredential对象，该对象包含一个getIdToken () 函数，该函数返回idToken您感兴趣的内容。最后，您可以登录 Firebase：

    if (credential is CustomCredential && credential.type == GoogleIdTokenCredential.TYPE_GOOGLE_ID_TOKEN_CREDENTIAL) {
    val googleIdTokenCredential = GoogleIdTokenCredential.createFrom(credential.data)
    val idToken = googleIdTokenCredential.idToken
    val authCredential = GoogleAuthProvider.getCredential(idToken, null)
    auth.signInWithCredential(authCredential).addOnCompleteListener(/* ... /*)
}
