title: How to put parameters in JSON in feature (karate framework)?
body: <p>I would like to send my parameters from:</p>
  
  <pre><code>* def d = call read ('datas.json')
  </code></pre>
  
  <p>in my method in js file:</p>
  
  <pre><code>* header Authorization = call read('basic-auth.js') { username: 'd.usn', password: 'd.pw' } 
  </code></pre>
  
  <p>(assuming that in datas.json I have <code>usn</code> and <code>pw</code>)</p>
  
  <p>instead of writing parameters '<code>john</code>' and '<code>secret</code>' </p>
  
  <pre><code>* header Authorization = call read('basic-auth.js') { username: 'john', password: 'secret' }
  </code></pre>
  
  <p>I'm sorry if I didn't find the information in official repo, but any answer would be very helpful: I needed this several times and didn't find an issue.</p>
