Retrieving JSON Object Literal from HttpServletRequest

Question

I am writing code that needs to extract an object literal posted to a servlet. I have studied the API for the HttpServletRequest object, but it is not clear to me how to get the JSON object out of the request since it is not posted from a form element on a web page.

Any insight is appreciated.

Thanks.

Answer 1

are you looking for this ?

@Override protected void doPost(HttpServletRequest request, HttpServletResponse response)         throws ServletException, IOException {     StringBuilder sb = new StringBuilder();     BufferedReader reader = request.getReader();     try {         String line;         while ((line = reader.readLine()) != null) {             sb.append(line).append('\n');         }     } finally {         reader.close();     }     System.out.println(sb.toString()); } 

Answer 2

This is simple method to get request data from HttpServletRequest using Java 8 Stream API:

String requestData = request.getReader().lines().collect(Collectors.joining());
