Answer 1

Although it's bit late, I would like to answer the question which is as below : You need to set the -vu values as username and password trough basic auth.

Answer 2

Short options can usually be combined, so -vu is the same as -v -u.

man curl says:

-v, --verbose
              Be  more  verbose/talkative during the operation. Useful for debugging and seeing what's going on "under the hood". A line starting with '>'
              means "header data" sent by curl, '<' means "header data" received by curl that is hidden in normal cases, and  a  line  starting  with  '*'
              means additional info provided by curl.
-u, --user <user:password>
              Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.
