获取post请求的几种常见方式

Posted 2022-01-19 4amljw

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

public static String req2RawString(HttpServletRequest request)
          StringBuilder sb = new StringBuilder();
          BufferedReader reader = null;
          try
              reader = request.getReader();
              String line;
              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);
          return str;
