Error 415: x-www-form-urlencoded versus JSON

Question

The web service accepts application/json, but $.ajax() with dataType : 'json' set just tries to send data as application/x-www-form-urlencoded. What's the trick here?

dataType: 'json' specifies that jQuery expects JSON back from the server (see docs). In order to specify that you are sending JSON, you need to add contentType: "application/json".

Furthermore, jQuery cannot convert an object into JSON for you. If you are passing any object to data, you need to stringify it yourself:

data: JSON.stringify(dataObject);
