How to handle request with content-type=application/json instead, encode, java, only

amy

I'd like to be able to handle JSON requests with the Content-Type in the header set to application/json, instead of uclencoded form parameters.  The client doesn't use DWR, so that's out, and I'm aware of JSONView, but AFAIK that's only for the response side.  Does anyone have a suggestion of how to handle this?

Thanks,
Mike Monette

Hi Mike,

Well when I'm sending JSON I use the library from to encode it.

There's also methods for creating a java object graph from a JSON string.

Take a look -

java/index.html

Thanks for replying.  My problem, though, isn't with sending JSON from the server (ie putting it in the response).  It's receiving JSON in the request with a Content-Type of application/json.

Are you asking how to get JSON string into an object graph that you can work with?

In your controller call getReader() on the fromServletRequest parameter, read the bytes into a string, for example, requestBody then call -

JSONObject requestObject = new JSONObject(requestBody);

Then, assuming you know the structure of the data than can be sent in the JSON string, you just call getters on the requestObject, e.g. If the request contains a field called 'comments'

String commentsField = jsonObj.get(quot;commentsquot;);

After processing it, just return whatever response is expected by the client of course.

This is exactly what I was looking for.  Thanks, Andy!
