发送阿里短信

Service代码

@Service
public class MsmServiceImpl implements MsmService {

    @Override
    public boolean send(Map<String, Object> param, String phone) {

        DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "AccessKeyId", "AccessKeySecret");
        IAcsClient client = new DefaultAcsClient(profile);

        // 固定的参数
        CommonRequest request = new CommonRequest();
        /// request.setProtocol(ProtocolType.HTTPS);
        request.setSysMethod(MethodType.POST);
        request.setSysDomain("dysmsapi.aliyuncs.com");
        request.setSysVersion("2017-05-25");
        request.setSysAction("SendSms");
        request.putQueryParameter("RegionId", "cn-hangzhou");
        
        // 模板数据
        request.putQueryParameter("PhoneNumbers",phone);
        request.putQueryParameter("SignName","xx博客网站");
        request.putQueryParameter("TemplateCode","短信模板ID");
        // 验证码数据
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param));

        try {
            CommonResponse response = client.getCommonResponse(request);
            boolean success = response.getHttpResponse().isSuccess();
            System.out.println(response.getData());
            return success;
        } catch (Exception e) {
            e.printStackTrace();
            return false;

Controller代码

@RestController
@RequestMapping("/edu/msm")
@AllArgsConstructor
public class MsmController {

    private RedisTemplate<String,String> redisTemplate;

    @Autowired
    private MsmService msmService;

    @GetMapping("sned/{phone}")
    public R sendMsm(@PathVariable String phone){
        // 从redis中获取数据
        String code = redisTemplate.opsForValue().get(phone);
        if (!StringUtils.isEmpty(code)){
            return R.ok();
        }
        code = RandomUtil.getFourBitRandom();
        Map<String, Object> param = new HashMap<>(16);
        param.put("code",code);
        // 调用service发送短信
        boolean isSend = msmService.send(param,phone);

        if (isSend){
            // 如果发送成功，把验证码放入redis中，并设置过期时间
            redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
            return R.ok();
        }else {
            return R.error().message("短信发送失败");
        }
    }
}
