1 Long: data 2 Short: d 3 Arg: <data> 4 Help: HTTP POST data 5 Protocols: HTTP MQTT 6 See-also: data-binary data-urlencode data-raw 7 Mutexed: form head upload-file 8 Category: important http post upload 9 Example: -d "name=curl" $URL 10 Example: -d "name=curl" -d "tool=cmdline" $URL 11 Example: -d @filename $URL 12 Added: 4.0 13 --- 14 Sends the specified data in a POST request to the HTTP server, in the same way 15 that a browser does when a user has filled in an HTML form and presses the 16 submit button. This will cause curl to pass the data to the server using the 17 content-type application/x-www-form-urlencoded. Compare to --form. 18 19 --data-raw is almost the same but does not have a special interpretation of 20 the @ character. To post data purely binary, you should instead use the 21 --data-binary option. To URL-encode the value of a form field you may use 22 --data-urlencode. 23 24 If any of these options is used more than once on the same command line, the 25 data pieces specified will be merged together with a separating 26 &-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post 27 chunk that looks like \&'name=daniel&skill=lousy'. 28 29 If you start the data with the letter @, the rest should be a file name to 30 read the data from, or - if you want curl to read the data from stdin. Posting 31 data from a file named \&'foobar' would thus be done with --data @foobar. When 32 --data is told to read from a file like that, carriage returns and newlines 33 will be stripped out. If you do not want the @ character to have a special 34 interpretation use --data-raw instead. 35
