获取post请求的数据

通常从http post请求获取数据的方法如下：

1.request.getInputStream()

2.request.getReader()

3.request.getParameterMap()系列

4.通过spring框架中的RequestBody或RequestParam

publicstaticString req2RawString(HttpServletRequest request) {

          StringBuilder sb =newStringBuilder();

          BufferedReader reader =null;

          try{

              reader = request.getReader();

              Stringline;

              while((line= reader.readLine()) != null) {

                   sb.append(line).append('\n');

              }

              if(sb.length() > 1) {

                   sb.replace(sb.length() - 1, sb.length(),"");

              }

          }

          catch(IOException e) {

              logger.info("RequestUtil,IOException:"+ e);

          }

          finally{

              if(reader !=null) {

                   try{

                        reader.close();

                   }

                   catch(IOException e) {

                        logger.info("RequestUtil,IOException:"+ e);

                   }

              }

          }

          String str = sb.toString();

          logger.info("Request Result:" + str);

          returnstr;
