從HttpServletRequest獲取POST數據的代碼

我們經常需要從HttpServletRequest對象獲取POST請求的數據，下面給出簡練的代碼共大家參考

 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*/ }

注意返回時應常會遇到中文亂碼問題，記得加上下面的兩個語句，設置response對象的字符集，

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