Firebase令牌身份验证错误

标签: android firebase firebase-realtime-database firebase-storage

我正在使用firebase存储来上传文件,但是当我上传时我收到此错误

E/StorageUtil: error getting token java.util.concurrent.ExecutionException: com.google.android.gms.internal.zzand: Please sign in before trying to get a token.

我用Google搜索但无法得到答案! 我已经登录了firebase。

我认为您在上传文件之前没有签名。在启动器活动的onCreate()中,尝试此代码

FirebaseAuth mAuth = FirebaseAuth.getInstance(); 

然后在onStart(),

FirebaseUser user = mAuth.getCurrentUser();
if (user != null) {
  // do your stuff
} else {
  signInAnonymously();
}

signInAnonymously()

private void signInAnonymously() {
    mAuth.signInAnonymously().addOnSuccessListener(this, new  OnSuccessListener<AuthResult>() {
            @Override
            public void onSuccess(AuthResult authResult) {
                // do your stuff
            }
        })
        .addOnFailureListener(this, new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception exception) {
                Log.e(TAG, "signInAnonymously:FAILURE", exception);
            }
        });
}

这可以解决您的问题

我遇到了同样的问题,这是因为默认情况下firebase只允许从已经过身份验证的用户上传文件。

在storage util异常之上,可能存在类似于此的日志:

E/StorageUtil: error getting token java.util.concurrent.ExecutionException: com.google.android.gms.internal.zzajb: Please sign in before trying to get a token.

我们有自己的身份验证过程而不使用firebase,因此我们决定更改firebase控制台中的存储规则。

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
    allow read, write;
    }
  }
}

注意:更改规则将允许任何用户将文件上传到您的Firebase云服务器。

以下步骤对我有用:

  1. 使用包ID从firebase生成正确的google-services.json

  2. 在build.gradle(app)

    pip3
  3. 确保在build.gradle(项目根文件夹)中添加以下依赖项

     dependencies {
    
     compile 'com.google.firebase:firebase-storage:10.2.0'
     compile 'com.google.firebase:firebase-auth:10.2.0'
     compile 'com.google.firebase:firebase-core:10.2.0'
     compile 'com.google.firebase:firebase-database:10.2.0'
     compile 'com.firebase:firebase-client-android:2.4.0'
     }
    
  4. 在活动中下载文件时,请添加以下代码:

    dependencies {
    
    classpath 'com.android.tools.build:gradle:2.2.3'
    classpath 'com.google.gms:google-services:3.0.0'
    
    }

也许你只是不能“开始”到firebase。我说这是因为我创建了一个项目,通过Android Studio IDE连接到firebase存储,但我必须在控制台上手动“开始”。

您必须先登录 FirebaseAuth。

您可以匿名登录,

但是如果您想登录用户的 google id,请尝试这样。

为了便于使用,我创建了一个管理器类。


  1. 创建(您的)GoogleUserManager 类

object YourGoogleUserManager {

    private lateinit var gso: GoogleSignInOptions
    private lateinit var firebaseAuth: FirebaseAuth

    fun init(context: Context) {
        firebaseAuth = FirebaseAuth.getInstance()
        gso = GoogleSignInOptions
            .Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(context.getString(R.string.default_web_client_id))
            .build()
    }

    fun startGoogleSignInForResult(
        fragment: Fragment,
        onSuccess: (AuthResult) -> Unit,
        onFail: (Exception) -> Unit
    ): ActivityResultLauncher<Intent> {
        return fragment.registerForActivityResult(
            ActivityResultContracts.StartActivityForResult()
        ) {
            val task = GoogleSignIn.getSignedInAccountFromIntent(it.data)
            handleGoogleSignInResult(task, onSuccess, onFail)
        }
    }

    fun signIn(
        activityResultLauncher: ActivityResultLauncher<Intent>,
        activity: Activity
    ) {

        val googleSignInClient = GoogleSignIn.getClient(activity, gso)

        activityResultLauncher.launch(googleSignInClient.signInIntent)
    }

    private fun handleGoogleSignInResult(
        task: Task<GoogleSignInAccount>,
        onSuccess: (AuthResult) -> Unit,
        onFail: (Exception) -> Unit
    ) {
        try {
            val account = task.getResult(ApiException::class.java)
            val credential = GoogleAuthProvider.getCredential(account?.idToken, null)
            firebaseAuth.signInWithCredential(credential)
                .addOnSuccessListener {
                    CatHolicLogger.log("success to firebase google sign in")
                    onSuccess(it)
                }
                .addOnFailureListener {
                    CatHolicLogger.log("fail to firebase google sign in")
                    onFail(it)
                }
        } catch (e: ApiException) {
            CatHolicLogger.log("fail to firebase google sign in")
            onFail(e)
        }
    }

    fun signOut() {
        firebaseAuth.signOut()
    }
}
  1. 在您的应用程序中初始化管理器。

class YourApplication : Application() {

    ...

    override fun onCreate() {
        super.onCreate()

        initGoogleUserManager()
    }

    ...

    private fun initGoogleUserManager() {
        YourGoogleUserManager.init(this)
    }
}
  1. 在您的片段(或活动)中使用管理器

class YourFragment : Fragment() {

    ...
    ...

    private val startGoogleSignInForResult =
        YourGoogleUserManager.startGoogleSignInForResult(this, onSuccess = {
            // your job after success to sign in
        }, onFail = {
            // your job after fail to sign in
        })

    ...
    ...

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        binding.signInButton.setOnClickListener {
            YourGoogleUserManager.signIn(startGoogleSignInForResult, requireActivity())
        }
    }
}

它可能就像互联网连接一样简单,即如果你的所有代码都是正确的,并且你已经在firebase上验证了所有用户。
