Android Tasksnapshot getDownloadUrl() 不同的 token

Question

我在将图片上传到 Firebase 时遇到问题。

当我上传图像时，我得到一个 taskSnapshot.getDownloadUrl() token ，当我查看 firebase 存储时，有一个不同的 token key 。我无法弄清楚我的问题出在哪里，也不是每次我都收到错误(大约 30% 的时间)。

希望你能帮助我。

我的上传方式:

 public void uploadImage(Context context, Activity activity) {
    String authorities = activity.getPackageName() + ".fileprovider";
    File f = new File(MainActivity.imagesPath + String.valueOf(uploadToiletId) + "_" + uploadTimeStamp + ".png");
    Log.i("HANDLERTAG", "file: " + f.getPath());
    Uri imageUri = FileProvider.getUriForFile(context, authorities, f);
    Log.i("HANDLERTAG", "image: " + imageUri.getPath());
    Bitmap bitmap;
    ByteArrayOutputStream baos;
    final DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference();
    final StorageReference storageRef = FirebaseStorage.getInstance().getReference();
    final FirebaseAuth mAuth = FirebaseAuth.getInstance();
    try {

        bitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), imageUri);
        Bitmap resized = Bitmap.createScaledBitmap(bitmap, bitmap.getWidth() / 4, bitmap.getHeight()/ 4, true);
        baos = new ByteArrayOutputStream();
        resized.compress(Bitmap.CompressFormat.PNG, 50, baos);
        byte[] dataBAOS = baos.toByteArray();
        final String timeStamp = FormatHelper.getCurrentDateTimeString("dd-MM-yy HH:mm:ss");
        StorageReference imagesRef = storageRef.child(String.valueOf(uploadToiletId)).child(timeStamp + ".png");
        imagesRef.putBytes(dataBAOS).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                Log.i("CAMERATAG", "Billede uploadet");
                Uri downloadUrl = taskSnapshot.getDownloadUrl();
                Log.i("DOWNLOAD_URL",String.valueOf(downloadUrl));
                HashMap<String, String> UploadImageMap = new HashMap<>();
                UploadImageMap.put("Url", downloadUrl.toString());
                UploadImageMap.put("UserId", mAuth.getCurrentUser().getUid());
                databaseRef.child(DB_TABLE_TOILETS)
                        .child(String.valueOf(uploadToiletId))
                        .child("Images")
                        .child(timeStamp).setValue(UploadImageMap);
                databaseRef.child(DB_TABLE_USERS)
                        .child(mAuth.getCurrentUser().getUid())
                        .child("Images")
                        .child(String.valueOf(uploadToiletId))
                        .child(timeStamp).setValue(UploadImageMap);
            }
        });
        imagesRef.putBytes(dataBAOS).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Log.i("CAMERATAG", e.getLocalizedMessage());
                Log.i("CAMERATAG", "Noget gik galt med billede");
            }
        });
        Toast.makeText(context, "Upload complete", Toast.LENGTH_SHORT).show();
    } catch (IOException e) {
        Log.i("HANDLERTAG", e.getMessage());
        e.printStackTrace();
    }
}

Debug shows token key from my app in android studio

token key :token=b23e8ab1-8322-46cf-889e-4f276fb2c242

Token from firebase

来自 firebase 的 token key :token=e5b84bed-7226-4af3-b01b-e31cf03e7d8b

您是否尝试过将存储设置为 read true？

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
        allow read;
      allow write: if request.auth != null;
    }
  }
}

这样用户无需登录即可阅读，但必须登录才能实际写入您的存储。
