这篇博客介绍了如何使用Ajax进行手机号码验证。首先通过Ajax调用Servlet发送短信验证码，然后在前端获取用户输入的验证码并再次通过Ajax发送到Servlet进行比对。如果验证码匹配，将密码修改为手机号后四位。涉及的技术包括jQuery、Ajax、Servlet、HTTP请求和短信发送API。

1.首先用ajax调用servlet

};
</script>

2.对应的两个servlet

@WebServlet("/code")
public class sendCodeServlet extends HttpServlet {

private static final long serialVersionUID = -8559217512617151073L;

   @Override
   protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
       // TODO Auto-generated method stub
       String phoneNumber = req.getParameter("phoneNumber");

       if (phoneNumber.trim().equals("") || phoneNumber == null) {
           resp.sendRedirect("show_All");
           return;
       }
       // 生成一个6位0~9之间的随机字符串
       StringBuffer buffer = new StringBuffer();
       Random random = new Random();
       for (int i = 0; i < 6; i++) {
           buffer.append(random.nextInt(10));
       }
       PrintWriter out = resp.getWriter();
       try {
           if (!SMScode.sendCode(phoneNumber, buffer.toString())) {
           } else {
               // 将验证码、手机号码和当前的系统时间存储到session中
               req.getSession().setAttribute("code", buffer.toString());
               req.getSession().setAttribute("number", phoneNumber);
               req.getSession().setAttribute("time", System.currentTimeMillis());
               // 将数据yitext传前台
               resp.getWriter().write(buffer.toString());
           }
       } catch (Exception e) {
           e.printStackTrace();
       }

out.close();
}

@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

doGet(req, resp);
}
}

@WebServlet("/code_reg")
public class RegCodes extends HttpServlet {
private static final long serialVersionUID = 1L;

   public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
       String codes = req.getParameter("codes");
        String phoneNumber = req.getParameter("phoneNumber");
       String code = (String) req.getSession().getAttribute("code");

       if (codes.equals(code)) {//两次验证一样，修改密码为手机后4位
           IUserService us=new UserServiceImpl();
           int updateUserByMobel = us.updateUserByMobel(phoneNumber);
           resp.getWriter().write(JSON.toJSONString(updateUserByMobel));
       }else {//失败修改
       resp.getWriter().write(JSON.toJSONString(0));
       }
   }

   public void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
       doGet(req, resp);
   }
}

3.发送验证码的方法

public class SMScode {

// 把手机号码和随机验证码传递过来
public static boolean sendCode(String phoneNumber, String code) throws Exception {

       String str_code = URLEncoder.encode("#code#=" + code, "UTF-8");
       // 包装好URL对象，将接口地址包装在此对象中
       URL url = new URL("http://v.juhe.cn/sms/send?mobile=" + phoneNumber + "&tpl_id={此处去聚合数据申请即可}&tpl_value=" + str_code
               + "&key={此处去聚合数据申请即}");
       /* 短信模板id */ /* 短信应用接口的key */
       // 打开连接，得到连接对象
       URLConnection connection = url.openConnection();
       // 向服务器发送连接请求
       connection.connect();
       // 获得服务器响应的数据
       BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
       StringBuffer buffer = new StringBuffer();
       String lineDate = null;
       while ((lineDate = bufferedReader.readLine()) != null) {
           buffer.append(lineDate);
       }
       bufferedReader.close();
       if (buffer.toString().indexOf("\"error_code\":0") >= 0) {
           return true;
       }

return false;
}
