--data-binary
This posts data exactly as specified with no extra processing whatsoever.
If you start the data with the letter @, the rest should be a filename. Data is posted in a similar manner as --data does, except that newlines and carriage returns are preserved and conversions are never done.
Like --data the default content-type sent to the server is application/x-www-form-urlencoded. If you want the data to be treated as arbitrary binary data by the server then set the content-type to octet-stream: -H "Content-Type: application/octet-stream".
If this option is used several times, the ones following the first append data as described in --data.
