当客户端提交数据后台来解析-IO
数据解析,保存遗产!强大内涵

一些看不懂的数据首先要确定他的编码格式,其次才能准确作出解析,可以拿一些数据,我博客里有一个小方法来判断是什么可是!!

BufferedReader是继承于Reader对象,从字符输入流中读取文本,缓冲各个字符,从而提供字符,数组和行的高效读取.

private String getRequestBody(HttpServletRequest request) throws  IOException{        StringBuilder stringBuilder = new StringBuilder();        BufferedReader bufferedReader = null;        try {            InputStream inputStream = request.getInputStream();            if (inputStream != null) {                bufferedReader = new BufferedReader(new InputStreamReader(                        inputStream,"utf-8"));                char[] charBuffer = new char[128];                int bytesRead = -1;                while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {                    stringBuilder.append(charBuffer, 0, bytesRead);                }            } else {                stringBuilder.append("");            }        } catch (IOException ex) {            throw ex;        } finally {            if (bufferedReader != null) {                try {                    bufferedReader.close();                } catch (IOException ex) {                    throw ex;                }            }        }        String body = stringBuilder.toString();        log.debug("get card back body:"+body);        return body;    }
