Question

尝试从FirebaseStorage获取公共downloadUrl时出现以下错误。我已经设置了规则以允许完全读写访问，并且将数据存储在存储中没有问题。但是，当我尝试获取下载URL时，我遇到了这个问题。 -

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

我已阅读Firebase getDownloadURL 但仍然无法解决我的问题。

这是我的功能 -

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == 0 && resultCode == RESULT_OK) {

            Uri uri = data.getData();
            final StorageReference filePath = mStorage.child("Photos").child(uri.getLastPathSegment());

            filePath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

//                    @SuppressWarnings("VisibleForTests") Uri downloadUri = taskSnapshot.getDownloadUrl();
//                    recognizeImage(downloadUri);

                    filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                        @Override
                        public void onSuccess(Uri uri) {
                            recognizeImage(uri);
                        }
                    });
                }

            });
        }
    }

请在Activity类

的onCreate方法中添加以下代码行

  mAuth = FirebaseAuth.getInstance();
    FirebaseUser user = mAuth.getCurrentUser();
    if (user != null) {

       /* perform your actions here*/


    } else {
        signInAsAnonymous();
    }

 private void signInAnonymously() {
    mAuth.signInAnonymously().addOnSuccessListener(this, new OnSuccessListener<AuthResult>() {
        @Override
        public void onSuccess(AuthResult authResult) {
                        /* perform your actions here*/

        }
    })
            .addOnFailureListener(this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    Log.e("MainActivity", "signFailed****** ", exception);
                }
            });
}

这还不足以解决您的问题。现在添加上面的代码。
