The set of valid parsers for a view is always defined as a list of classes. When either `request.DATA` or `request.FILES` is accessed, REST framework will examine the `Content-Type` header on the incoming request, and determine which parser to use to parse the request content.
---
**Note**: When developing client applications always remember to make sure you're setting the `Content-Type` header when sending data in an HTTP request.
If you don't set the content type, most clients will default to using `'application/x-www-form-urlencoded'`, which may not be what you wanted.
As an example, if you are sending `json` encoded data using jQuery with the [.ajax() method][jquery-ajax], you should make sure to include the `contentType: 'application/json'` setting.
