若依实现手机验证码登入功能及企业微信机器人预警功能

若依框架实现验证码登入
有效期为5分钟，由于阿里电话短信服务有同一appCode给同一用户10分钟最多只能发送3条短信的限制，这里尽可能的提高用户的体验度和系统的可用性！有设置了2分钟不可重复发送的限制。
查询redis对用key所剩时间的代码如下：

Long phoneLong = redisTemplate.opsForValue().getOperations().getExpire(phone);

可以看得到获取得到的数据类型是long，单位是秒。

主要代码如下

//发送短信的方法,短信都是要发送到手机上的,所以会需要手机号
    @PostMapping("send/{phone}")
    public AjaxResult sendMsm(@PathVariable String phone){
        //1.从redis中获取验证码,如果获取到则直接返回
        String code = redisCache.getCacheObject(phone);
        if (!StringUtils.isEmpty(code)){
            //获取redis数据过期时间
            Long phoneLong = redisTemplate.opsForValue().getOperations().getExpire(phone);
            if (phoneLong > 180L){
                return AjaxResult.error("验证发已送达，请不要在两分钟内重复发送");
            }
//            System.out.println("key的过期时间："+phoneLong);
            redisCache.deleteObject(phone);
//            return AjaxResult.error("验证发已送达，请不要重复发送");
        }
        //2.获取不到的话,那直接生成发送
        //生成随机的值,传递给阿里云进行发送
        String str="0123456789";
        StringBuilder sb=new StringBuilder(4);
        for(int i=0;i<4;i++) {
            char ch = str.charAt(new Random().nextInt(str.length()));
            sb.append(ch);
        }
        code = sb.toString();
        Map<String,Object> param = new HashMap<>();
        param.put("code",code);
        //调用service发送短信方法
        boolean isSend = msmService.send(param,phone);
        if (isSend){
            //发送成功,把发送成功的验证码放到redis中去,同时设置有效时间
//            redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);//设置了五分钟的有效时长
            // 保存验证码信息
            String uuid = IdUtils.simpleUUID(); //生成一个uuid
            String verifyKey = CacheConstants.CAPTCHA_CODE_KEY + uuid;
            redisCache.setCacheObject(verifyKey, code, 5, TimeUnit.MINUTES);
            redisCache.setCacheObject(phone, code, 5, TimeUnit.MINUTES);
//            System.out.println("已经打入redis中");
            return AjaxResult.success();
        }else {
            return AjaxResult.error("短信发送失败");
        }
    }

send方法对应service代码如下

package com.ruoyi.system.service;

import java.util.Map;

public interface MsmService {
    boolean send(Map<String, Object> param, String phone);

    /**
     * v2登录接口（自建应用）
     * @param text
     * @return
     */
    void postXiaoRun(String text);
}

send对应imp代码如下

}

从上面不难发现，有很多关于发送状态的提示！考虑到购买短信服务的手机号不在你我手里所以这里添加一个机器人提醒的功能还是很有必要的！如果没有在程序因为条数不够而报错时咱们只能背黑锅了！这里务必要加上！

}

需要阿里的jar引入代码如下

        <!--案例云-电话发送验证码-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.2.1</version>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpcore</artifactId>
            <version>4.2.1</version>
        </dependency>

基本上就这些了，要是还有什么没有提到的请积极沟通一起进步！
