title: Postman form-data works, but the raw equivalent doesn't
body: <p>I have an API that I'm testing with and if I submit my data through "form-data" with the following values it works:</p>
  
  <pre><code>key: response[comment]
  value: This is a test
  </code></pre>
  
  <p>But if I do some custom JSON in the "raw" tab with the following structure, it doesn't work:</p>
  
  <pre><code>{ "response[comment]": "This is a test" }
  </code></pre>
  
  <p>It's driving me nuts to be honest as the server doesn't give me any details on what's wrong.
  I have the feeling it's the encoding of the object that goes wrong, but I'm using Angular and I get the same 400 error, while I'm fairly sure it should just work with a JS object as the data on a .post.</p>
  
  <p>Any help would be appreciated!</p>
