title: Using flowfile content
body: <p>New to NiFi!</p>
  
  <p>I've split a flowfile into a single line of text using splitJSON processor.</p>
  
  <p>The NiFi flowfile contents are as follows:</p>
  
  <pre><code>abcdefg
  </code></pre>
  
  <p>I'd like to be able to take the text in the flowfile and either add it to a url to make a subsequent call using InvokeHTTP or add the contents of the flowfile as an attribute so I can make the subsequent call using InvokeHTTP like so</p>
  
  <p><a href="http://localhost/" rel="nofollow noreferrer">http://localhost/</a><strong>${my.newly.added.attribute}</strong> </p>
  
  <p>How do i do this?</p>
  
  <p>Any help would be appreciated!
  Thanks in advance!</p>
