get value from http post request

 

We all know that the parameter value submitted by the get method can be obtained from the http request through request.getParameter("someParam"), then what about the body (such as xml, json, etc.) in the post request?

private String getRequestBody(final HttpServletRequest request) {
		
		String charset = request.getCharacterEncoding();   
		 if (charset == null) {   
		     charset = DEFAULT_ENCODE;   
		 }  
		 String str, wholeStr;
		try {
			BufferedReader br = request.getReader();
			 wholeStr = "";
			 while((str = br.readLine()) != null){
			 wholeStr += str;
			 }
			 return wholeStr;
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace ();
		}
}
