title: How to do HTTP-request/call with JSON payload from command-line?
body: <p>What's the easiest way to do a JSON call from the command-line? I have a website that does a JSON call to retrieve additional data.</p>
  
  <p>The <strong>Request Payload</strong> as shown in Google Chrome looks like this:</p>
  
  <pre><code>{"version": "1.1", "method":"progr","id":2,"params":{"call":...} }
  </code></pre>
  
  <p>It's about doing the call from (preferably) linux command line and retrieving the JSON content, not about parsing the incoming JSON data.</p>
