java 流获取请求的body参数

定义一个工具类。每次要获取时候直接 String inputstr =
GetInputStr(request);  inputstr   就是请求过来的参数

public String
GetInputStr(HttpServletRequest request)

    {

        BufferedReader br = null;

        try {

            br = new BufferedReader(new InputStreamReader(request.getInputStream(), "UTF-8"));

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        String line = null;

        StringBuilder sb = new StringBuilder();

        try {

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

                sb.append(line);

            }

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        return sb.toString();

    }
