objectContents - The input stream containing the object contents retrieved from COS

rangeBeginning - The position of the left-most byte desired by the user

rangeEnd - The position of the right-most byte desired by the user

抛出:

IOException - If there are errors skipping to the left-most byte desired by the user.
