定義一個工具類。每次要獲取時候直接 String inputstr = GetInputStr(request);  inputstr   就是請求過來的參數

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();
    }
