What is the cURL command-line syntax to do a POST request?

For a RESTful HTTP POST containing XML:

curl -X POST -d @filename.txt examplewebsite/path/to/resource --header "Content-Type:text/xml"

or for JSON, use this:

curl -X POST -d @filename.txt examplewebsite/path/to/resource --header "Content-Type:application/json"

This will read the contents of the file named filename.txt and send it as the post request.

Data from stdin with -d @-

Example:

echo '{"text": "Hello world!"}' | curl -d @- any url

Output:

<p>Hello <strong>world</strong>!</p>
