我想将s3 bucket1中的一些文件（视频）写入s3bucket2作为邮件，而不使用任何磁盘空间进行临时存储。它应该在最短的时间内以较少的开销发生。目前我正在使用zipstream制作zip，但是无法快速写入存储桶。任何帮助都是预先确定的。

是的，你可以。如果您将对象作为字符串存储在内存中，只需使用public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.CustomViewHolder> {
private List<SingleItemModel> singleItemList;
private Context mContext;
private OnItemClickListener onItemClickListener;
public MyRecyclerViewAdapter(Context context, List<SingleItemModel> singleItemList) {
this.singleItemList = singleItemList;
this.mContext = context;
}
@Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_row, null);
CustomViewHolder viewHolder = new CustomViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(CustomViewHolder customViewHolder, int i) {
final SingleItemModel feedItem = singleItemList.get(i);
//Download image using picasso library
if (!TextUtils.isEmpty(feedItem.getUrl())) {
Picasso.with(mContext).load(feedItem.getUrl())
.error(R.drawable.placeholder)
.placeholder(R.drawable.placeholder)
.into(customViewHolder.imageView);
}
//Setting text view title
customViewHolder.textView.setText(feedItem.getName());
View.OnClickListener listener = new View.OnClickListener() {
@Override
public void onClick(View v) {
onItemClickListener.onItemClick(feedItem);
}
};
customViewHolder.imageView.setOnClickListener(listener);
customViewHolder.textView.setOnClickListener(listener);
}
@Override
public int getItemCount() {
return (null != singleItemList ? singleItemList.size() : 0);
}
class CustomViewHolder extends RecyclerView.ViewHolder {
protected ImageView imageView;
protected TextView textView;
public CustomViewHolder(View view) {
super(view);
this.imageView = (ImageView) view.findViewById(R.id.thumbnail);
this.textView = (TextView) view.findViewById(R.id.title);
}
}
public OnItemClickListener getOnItemClickListener() {
return onItemClickListener;
}
public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
this.onItemClickListener = onItemClickListener;
}
。
file_put_contents这完全合法，因为PHP SDK支持支持流包装：http://docs.aws.amazon.com/aws-sdk-php/v2/guide/feature-s3-stream-wrapper.html
