Firebase令牌验证错误 [英] Firebase Token Authentication error

问题描述

  E / StorageUtil：error 
使用firebase存储上传文件，但是当我上传时，获取令牌java.util.concurrent.ExecutionException：com.google.android.gms.internal.zzand：请在尝试获取令牌之前登录。 
  

我用Google搜索了一下，但无法得到答案！
我已经在firebase中登录了。

解决方案

我想你在上传文件之前没有登录。在启动程序活动的onCreate（）中，试试这个代码

  FirebaseAuth mAuth = FirebaseAuth.getInstance（）; 
  

然后在onStart（），

  FirebaseUser user = mAuth.getCurrentUser（）; 
 if（user！= null）{
 //做你的东西
} else {
 signInAnonymously（）; 
 
 
 
 $ b 
 signInAnonymously（）
 
 
  
  < （），这个新的OnSuccessListener< AuthResult>（）{
 @Override 
 public void setInnonymous（）{
 mAuth.signInAnonymously（） void onSuccess（AuthResult authResult）{
 //做你的东西
} 
}）
 .addOnFailureListener（this，new OnFailureListener（）{
 @Override 
 public void onFailure（@NonNull exception exception）{
 Log.e（TAG，signInAnonymously：FAILURE，exception）; 
} 
}）; 
 
  

这可能会解决您的问题

I am using firebase storage to upload files , but when I upload I am getting this error

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

I googled it but couldn't get answer for it! I have signed in, in firebase.

解决方案

I think you didn't sign before uploading files. In onCreate() of launcher activity, try this code

FirebaseAuth mAuth = FirebaseAuth.getInstance(); 

Then in 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);
            }
        });
}

This may solve your problem
