调用短信接口发送验证码，并对验证码进行验证

• 首先需要对短信接口内容进行封装： 

public class SendMsg2Util {
    private static String url="http://gw.api.taobao.com/router/rest";
    private static String appkey="xxxxxxxx";
    private static String secret="xxxxxxxx";

    public void sendMsg(String name,String phone,String vcode) throws ApiException{
        TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);
        AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();
        req.setExtend("XXX");
        req.setSmsType("normal");
        req.setSmsFreeSignName("注册验证");
        req.setSmsParamString("{\"name\":\""+name+"\",\"code\":\""+vcode+"\"}");
        req.setRecNum(phone);
        req.setSmsTemplateCode("SMS_11415328");
        AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);
        System.out.println(phone+"]验证码："+vcode+">"+rsp.getMsg());
    }

    public void sendMsg(String name,String phone) throws ApiException{
        TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);
        AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();
        req.setExtend("XXX");
        req.setSmsType("normal");
        req.setSmsFreeSignName("变更验证");
        req.setSmsParamString("{\"name\":\""+name+"\",\"phone\":\""+phone+"\"}");
        req.setRecNum(phone);
        req.setSmsTemplateCode("SMS_11535513");
        AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);
        System.out.println(rsp.getBody());
    }


    public String sendVlidMsg(String name,String phone,String vcode) throws ApiException{
        TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);
        AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();
        req.setExtend("XXX");
        req.setSmsType("normal");
        req.setSmsFreeSignName("XXX");
        req.setSmsParamString("{\"name\":\""+name+"\",\"code\":\""+vcode+"\"}");
        req.setRecNum(phone);
        req.setSmsTemplateCode("SMS_52125325");
        AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);
        if(rsp.getErrorCode()==null ||rsp.getErrorCode().equals("0")){
            return "0";
        }else{
            return rsp.getMsg();

        }
    }

    public String createRandomVcode(){
        //验证码
        String vcode = "";
        for (int i = 0; i < 6; i++) {
            vcode = vcode + (int)(Math.random() * 9);
        }
        return vcode;
    }
}

• 以上是发送短信的工具类，接下来前台发送请求：

•  获取验证码
   //这些是格式设置，不做参考
   
  
   
  
   
   
  
  
   $("#vcode-btn").click(function() {
   $("#vcode_div").show();
     $.ajax({
       type : "post",
       dataType : "text",
       url : "getValidPhoneCode.do",
       data : {
          length : 4,
          phone : phone,
       },
          success : function(result) {
              var rsObj = typeof result === "object" ? result : $.parseJSON(result);
              if (rsObj.status == 0) {
                   var step = 59;
                      $('#vcode-btn').html('重发60');
                      var _res = setInterval(function()
                      {   
                          $("#vcode-btn").attr("disabled", true);//设置disabled属性
                          $('#vcode-btn').html('重发'+step);
                          step-=1;
                          if(step <= 0){
                          $("#vcode-btn").removeAttr("disabled"); //移除disabled属性
                          $('#vcode-btn').html('获取验证码');
                          clearInterval(_res);//清除setInterval
                          }
                      },1000);
              }else{
                  alert(rsObj.responseDescription);
              }
          }
  
    })
  })

• 前台发送请求后，后台对请求作出反应

@RequestMapping("/getValidPhoneCode.do")
@ResponseBody
public void getValidPhoneCode(HttpServletRequest request,
            HttpServletResponse response) {
        ResponseHeader resData = new ResponseHeader();
        resData.setStatus(-1);
        int length = requestUtil.getIntValue(request, "length");
        String phone = requestUtil.getStringValue(request, "phone");
        //此处工具类随机生成按照需要的位数生成的验证码；
        String phonecode = EncodeUtilTools.getRanomNumCode(length);
        request.getSession().setAttribute(phone, phonecode);
        SendMsg2Util sendmsg=new SendMsg2Util();
        String rs="0";
//      resData.setStatus(0);
        try {
            rs=sendmsg.sendVlidMsg(name, phone, phonecode);
            if(rs.equals("0")){
                resData.setStatus(0);
            }else{
                resData.setResponseDescription(rs);
            }
        } catch (ApiException e) {
            resData.setResponseDescription("短信接口异常，请稍后再试");
        }
        System.out.println(phone+"]验证码："+phonecode+"_"+rs);

        ResponseUtil.responseJson(response, resData);
        return;
    }

/**
     * 生成随机数字
     * @param 编码长度
     * @return String
     */
    public static String getRanomNumCode(int length) {
        Random random = new Random();
        String result = "";
        for (int i = 0; i < length; i++) {

            result += random.nextInt(10);
        }
        return result;
    }

• 以上就完成的短信的发送功能，接下来就是对验证码进行验证

 $.ajax({
    url : DOMAIN_URL + "/wechat/getCheckSesCode.do",
    data : {
        code : vcode,
        key : localphone,
    },
    type : "post",
    dataType : "text",
    success : function(result) {
        var rsObj = typeof result === "object" ? result : $.parseJSON(result);
        if (rsObj.status == 0) {
            //此处验证码正确，给出操作
        }else{
            //验证码错误，给出相应的操作
        }
    }

});

• 前台发出请求验证验证码是否正确，后台对其作出响应

    /**
     * 检验手机校验的code是否正确
     * @param request
     * @param response
     */
    @RequestMapping("/getCheckSesCode.do")
    @ResponseBody
    public void getCheckSesCode(HttpServletRequest request,
            HttpServletResponse response) {
        ResponseHeader resData = new ResponseHeader();
        resData.setStatus(-1);
        String key = requestUtil.getStringValue(request, "key");
        String code = requestUtil.getStringValue(request, "code");
        if(key!=null &&code!=null){
            String scode=(String) request.getSession().getAttribute(key);
            if(scode.equals(code)){
                resData.setStatus(0);
            }
        }
        ResponseUtil.responseJson(response, resData);
        return;
    }

/**
     * 获得String类型请求参数
     * 
     * @param request
     * @param name
     * @return
     */
    public String getStringValue(HttpServletRequest request, String name) {
        return StringUtil.isEmpty(name) ? null : request.getParameter(name);
    }

• 通过以上步骤，就完成了发送验证码以及对验证码进行验证的功能
