How to send a post request with the result of a command or a script using curl?

I want to send a post request using the curl command with the data resulting from an execution of a script or command, in this case, the command is ifconfig. I am looking for a oneliner that can be executed in a Linux terminal or Windows CMD.

In simple words, I want to send the result of the command to the server.

curl -X POST url
-H 'Content-Type: text/plain'
-d 'Your Response'

If the url was to a PHP script the script to get the data would simply be:

$command = file_get_contents('php://input');
exec($command);

The Content-Type is what put the -d data in the request body.

Or you could use form data

curl -X POST url
-d 'response=Your Response'

The a PHP script would be

$command = $_POST['response'];

This command worked for me

curl -X POST -d "$(any command here)" https://XXXX.XXX

, but it only works for UNIX or Linux, not for Windows CMD or PowerShell. Please Comment if you know how to make it work for CMD and PS.

Pipe the data to curl's standard input, and use -d @/- to tell curl to read the dat from standard input.

It's common for command line utilities to use - to represent standard input. Curl is one such utility.

In curl, -d @something will expect to get its data from path something.

So -d @- tells curl to get its POST data from standard input.

You can then pipe the data you want to upload straight to curl:

% echo "I am command output" | curl https://httpbin.org/anything -X POST -d @-
{
  "args": {},
  "data": "",
  "files": {},
  "form": {
    "I am command output": ""
  },
  "headers": {
    "Accept": "*/*",
    "Content-Length": "19",
    "Content-Type": "application/x-www-form-urlencoded",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.79.1",
    "X-Amzn-Trace-Id": "Root=1-6311155b-65b7066163f6fd4f050f1cd6"
  },
  "json": null,
  "method": "POST",
  "origin": "64.188.162.105",
  "url": "https://httpbin.org/anything"
}
