Android firebase在尝试访问存储时引发身份验证错误

Question

编辑：我刚刚在清理项目并使缓存无效后重新启动了Android Studio。现在我发现了这个错误-

E/StorageException: {  "error": {    "code": 403,    "message": 
"Permission denied. Could not perform this operation"  }}

下面的错误会无限打印。

            fstore.child("gs://XXXXXX-XXXX.appspot.com/Books/XXXX").listAll().addOnSuccessListener(new OnSuccessListener<ListResult>() {
            @Override
            public void onSuccess(ListResult listResult) {
                for(StorageReference sref : listResult.getItems())
                {
                    tempFilename = sref.getName();
                    File tmpFile = new File(tempSubDir, tempFilename);
                    try {
                        tmpFile.createNewFile();
                        sref.getFile(tmpFile).addOnFailureListener(new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                Toast.makeText(tabtwoactivity.this, "File download failed!", Toast.LENGTH_LONG).show();
                                System.out.println("ERROR: "+ e.toString());
                            }
                        });
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    //System.out.println("IIIIII: "+sref.getName());
                }
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(tabtwoactivity.this, "Fetching Directory XXXXX Failed", Toast.LENGTH_LONG).show();
            }
        });

我做错了什么？

Answer 1

service firebase.storage {
  // The {bucket} wildcard indicates we match files in all storage buckets
  match /b/{bucket}/o {
    // Match filename
    match /filename {
      allow read: if true;
      allow write: if true;
    }
  }
}
