The -d section in the man page says:

  If you start the data with the letter @, the rest should be a file name to
  read the data from, or - if you want curl to read the data from stdin. The
  contents of the file must already be url-encoded. Multiple files can also
  be specified. Posting data from a file named 'foobar' would thus be done
  with "--data @foobar".

You can also use -K to specify a config file in which you can use the -d
option, which also would hide the data from ps outputs etc.
