title: Send "raw" payload to Axios
body: <p>How can I send a raw payload/request body to Axios?</p>
  
  <p>The endpoint I'm trying to call expects the request body to just be a string which it'll scoop up and use.</p>
  
  <p>If I try to just pass a string to <code>axios.post()</code> for the <code>requestBody</code>, it'll convert it to an object with no value (<code>{ "this+is+my+message": "" }</code>) and ends up getting parsed like this <code>"this+is+my+message="</code>.</p>
  
  <p>I checked the documentation, but couldn't find any option that seemed to work. <code>transformRequest</code> seemed to be the most obvious, but it sent in the string and I sent out the string (literally <code>d =&gt; d</code>), but it still seemed to convert it to a valueless JSON object.</p>
