android - 自定义 Firebase 身份验证：令牌格式不正确错误

问题描述

我正在尝试使用自定义登录来使用 google 登录登录 Firebase，但无法登录。firbase 抛出的错误是com.google.firebase.auth.FirebaseAuthInvalidCredentialsException：自定义令牌格式不正确。请检查文档。请注意令牌尚未过期。

我检查了 google post login 共享的 IdToken 但在 jwt.io 上是否正确读取？任何人都可以指导这个问题吗？使用 Google 的自定义登录，因为我需要 refrsh 令牌，因为我需要 google apis 来持续访问 apis... 通过代码如下：

class WelcomeActivity : AppCompatActivity() {

    var firebaseUser: FirebaseUser? = null
    //For Google Sign In
    val RC_SIGN_IN: Int = 9001
    private lateinit var mGoogleSignInClient: GoogleSignInClient
    lateinit var mGoogleSignInOptions: GoogleSignInOptions
    private lateinit var firebaseAuth: FirebaseAuth
    private var firebaseUserID : String = ""
    private lateinit var refUsers : DatabaseReference

    //get data from google signin
    private var googleId  = ""
    private var googleFirstName = ""
    private var googleLastName = ""
    private var googleEmail = ""
    private var googleProfilePicURL = ""

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_welcome)

    //        //For google sign in
    //        configureGoogleSignIn()
    //        setupUI()
        firebaseAuth = FirebaseAuth.getInstance()

        val gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken("896894788293-oe0enptjj2hltdde9isemuf89gtkb7u4.apps.googleusercontent.com")
            .requestEmail()
            .build()

        mGoogleSignInClient = GoogleSignIn.getClient(this, gso)

        google_login.setOnClickListener {
            signIn()
        }

        signup_welcome.setOnClickListener {
            val intent = Intent(this@WelcomeActivity, RegisterActivity::class.java)
            startActivity(intent)
            finish()
        }
        login_welcome.setOnClickListener {
            val intent = Intent(this@WelcomeActivity, LoginActivity::class.java)
            startActivity(intent)
            finish()
        }
    }

    private fun signIn() {
        val signInIntent = mGoogleSignInClient.signInIntent
        startActivityForResult(signInIntent, RC_SIGN_IN)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == RC_SIGN_IN) {
            val task =
                GoogleSignIn.getSignedInAccountFromIntent(data)
                handleSignInResult(task)
        }
    }

    private fun handleSignInResult(completedTask: Task<GoogleSignInAccount>) {
        try {
            val account = completedTask.getResult(
                ApiException::class.java
            )
            // Signed in successfully
            googleId = account?.id ?: ""
            Log.i("Google ID", googleId)

            googleFirstName = account?.givenName ?: ""

            googleProfilePicURL = account?.photoUrl.toString()
            Log.i("Google Profile Pic URL", googleProfilePicURL)

            val googleAccessToken = account?.serverAuthCode ?: ""
            Log.i("Google Server Auth Code", googleAccessToken)

            firebaseLogIn(googleIdToken)


        } catch (e: ApiException) {
            // Sign in was unsuccessful
            Log.e("failed code=", e.statusCode.toString()
            )
        }
