android - 如何将图像上传到 Firebase 存储？

Question

我正在尝试将一个简单的字节数组上传到 Firebase 存储中，但我的 onFailureListener 一直被调用并返回给我说上传失败。我希望你们能告诉我我的代码有什么问题。

在顶部我得到了

 //Firebase
    private Firebase mRef;
    private StorageReference storageRef;

然后在onStart()

@Override
protected void onStart() {
    super.onStart();
    googleApiClient.connect();
    //Firebase
    mRef = new Firebase("link to firebase account");
    FirebaseStorage storage = FirebaseStorage.getInstance();
    storageRef = storage.getReferenceFromUrl("link to storage");

}

然后在我的onActivityResult()

      @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            addImageImageView.setVisibility(View.GONE);
            if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK && data != null) {
                //First we gotta make sure to add the images to
                ArrayList<Image> imagesFromGallery = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);
                for (int i = 0; i < imagesFromGallery.size(); i++) 
                {
                    try {
                        //try uploading it
                        InputStream stream = new FileInputStream(new File(imagesFromGallery.get(i).path));
                        StorageReference imageStorage = storageRef.child("cardImages/" + "testImages");
                        UploadTask uploadTask = imageStorage.putStream(stream);
                        uploadTask.addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Log.d("myStorage","failure :(");
                        }
                    }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            Log.d("myStorage","success!");
                        }
                    });
                    catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                    } catch (FileNotFoundException e) {
                     e.printStackTrace();
                }
           }
      }

这是我的堆栈跟踪:

您需要让用户登录或更改安全规则以允许公共(public)访问。 Firebase Storage Security 的文档中对此进行了解释.

对于初始开发，您可以在 Firebase 控制台更改规则以允许公共(public)访问:

service firebase.storage {
  match /b/project-XXXXXXXXXXXXXX.appspot.com/o {
    match /{allPaths=**} {
      // Provide access to all users
      allow read: if true;
      allow write: if true;
    }
  }
}
