HttpServletRequest获取post的参数

2019独角兽企业重金招聘Python工程师标准>>>

HttpServletRequest获取post的参数 同事的错误写法：

    public @ResponseBody String registerLogin(HttpServletRequest request, HttpServletResponse response) {
//        String userName = request.getParameter("userName");

正确：

try {
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null)
        sb.append(line);
    service = sb.toString();
} catch (Exception e) {
    e.printStackTrace();
}
