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;
}
