How to add random value in Json Body in Gatling? : <p>I need to create a random positive integer each time and send it to Json body in Gatling.</p>

<p>I used the below code to create a random positive ineger:</p>

<pre><code>val  r = new scala.util.Random;
val OrderRef = r.nextInt(Integer.MAX_VALUE);
</code></pre>

<p>but, How can I feed the randomly generated value into the json body?</p>

<p>I tried:</p>

<pre><code>.exec(http("OrderCreation")
.post("/abc/orders")
.body(StringBody("""{    "orderReference": "${OrderRef}"}""").asJson)  
</code></pre>

<p>But, this doesn't seem to work. Any clues please.</p>

<p>Thanks!</p>
