从HttpServletRequest获取POST数据的代码

我们经常需要从HttpServletRequest对象获取POST请求的数据，下面给出简练的代码共大家参考

 StringBuffer jb = new StringBuffer();

  String line = null;

  try {

    BufferedReader reader = request.getReader();

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

      jb.append(line);

  } catch (Exception e) { /*report an error*/ }

注意返回时应常会遇到中文乱码问题，记得加上下面的两个语句，设置response对象的字符集，

response.setCharacterEncoding("GBK");

response.setContentType("application/xml; charset=GBK");
