title: Content types for file upload
body: <p>I wanted to upload a file(any format) to an api. If I upload the file using multipart/form-data then the file gets uploaded. </p>
  
  <p>I wanted to upload the file using application/json  as the Content-type  in the header. 
  Could you'll tell me if this method is possible/allowed?</p>
  
  <p>Which are Content-type besides multipart/form-data which supports file upload?</p>
  
  <p>Is there a single standard for content type which can be used for get, put, post etc.</p>
  
  <p>Thanks in Advance.</p>
