| Sends the specified data in a POST request to the HTTP server, in the same way |
| that a browser does when a user has filled in an HTML form and presses the |
| submit button. This will cause curl to pass the data to the server using the |
| content-type application/x-www-form-urlencoded. Compare to --form. |
| |
| --data-raw is almost the same but does not have a special interpretation of |
| the @ character. To post data purely binary, you should instead use the |
| --data-binary option. To URL-encode the value of a form field you may use |
| --data-urlencode. |
| |
| If any of these options is used more than once on the same command line, the |
| data pieces specified will be merged with a separating &-symbol. Thus, using |
| \&'-d name=daniel -d skill=lousy' would generate a post chunk that looks like |
| \&'name=daniel&skill=lousy'. |
| |
| 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. Posting |
| data from a file named \&'foobar' would thus be done with --data @foobar. When |
| --data is told to read from a file like that, carriage returns and newlines |
| will be stripped out. If you do not want the @ character to have a special |
| interpretation use --data-raw instead. |
