title: In Azure Functions, how to use route parameter inside an output binding
body: <p>Below is an http triggered function. For the route, I have specified a variable <code>user</code>. Now, I want this variable <code>user</code> to be consumed in <em>any other</em> output binding. <strong>Now working</strong> code shown with <code>Blob</code> as an output binding.</p>
  
  <pre><code>[FunctionName(nameof(Greeting))]
  public static IActionResult Run(
  [HttpTrigger(AuthorizationLevel.Function, "post", Route = "{user}/greeting")] HttpRequest req,
  string user,
  [Blob("{user}", Connection = "MyStorageAccount")] CloudBlockBlob blob)
      =&gt; new OkResult();
  </code></pre>
  
  <p>N.B. I'm not actually interested in creating a blob. Just interested in the syntax that works.</p>
  
  <p>Edit: Just realising that this works perfectly. </p>
