使用当前用户的UID将图像上传到Firebase存储

问题描述：

您如何上传同时附加了当前用户的UID的图像?

How do you upload an image that will also have the current user's UID attached?

以下示例.

这是我用来上传图片的代码，但到目前为止，添加UID都没有成功.

This is the code I am using to upload the image, but so far having no success adding on the UID.

private void updloadImage(Uri pickedImage){
        StorageReference myStorage = FirebaseStorage.getInstance().getReference().child("users_photos");
        final StorageReference imagePath = myStorage.child(pickedImage.getLastPathSegment());
        userID = fAuth.getCurrentUser().getUid();
        imagePath.putFile(pickedImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                imagePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        UserProfileChangeRequest myUpdate = new UserProfileChangeRequest.Builder().setPhotoUri(uri).build();


                    }
                });
            }
        });

如果您希望用户的UID成为Cloud Storage中映像文件名的一部分，则可以执行以下操作:

If you want the user's UID to be part of the image file name in Cloud Storage, you'd do:

StorageReference myStorage = FirebaseStorage.getInstance().getReference().child("users_photos");
final StorageReference imagePath = myStorage.child(pickedImage.getLastPathSegment());
userID = fAuth.getCurrentUser().getUid();
imagePath.putFile(userID+"_"+pickedImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

如果您希望用户的图像基于用户的UID放在子文件夹中，则可以将最后一行更改为:

If you instead want the image(s) for a user to end up in a subfolder based on their UID, you'd change that last line to:

imagePath.child(userID).putFile(pickedImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

使用当前用户的UID将图像上传到Firebase存储
