How to get FORM / POST parameters in a spring controller?

Question

I have the following answer, which should come from the MailChimp URL .

This is the BODY line:

RAW BODY

I used it @RequestParameterearlier when working with Spring controllers, however I'm not sure how to get data from the above answer, for example, data [merges] [FNAME] :

How can I get a QueryString inside a Spring controller? QUERYSTRING: a4483983hu473004884j0x

//I have the following code to begin with
@RequestMapping("/unsubscribewebhook")
    public ZapJasonMessage unsubscribeWebHook(
    @RequestParam("key") String key,
    @RequestParam ("data[merges][FNAME]") String firstName
) {

}

I appreciate your help!

You just need to enter WebRequest as a parameter in your controller POST method, and then request getParameter () with the given parameter from the Mailchimp website.

eg:

@RequestMapping(path="/MyUrl", method=RequestMethod.POST)
public ModelAndView process(WebRequest request){
    System.out.println(request.getParameter("type"));
    System.out.println(request.getParameter("data[merges][EMAIL]"));
    return new ModelAndView([YOURVIEWHERE]);
}

What all...
