Spring Boot + Redis使用短信平台发送验证码(腾讯云短信平台)

如题。

我这里使用的是腾讯云短信平台，理由是，首次开通赠送100条短信

在个人实名认证之后，进入https://cloud.tencent.com/act/free

根据步骤，进行模板的填写和申请

接下来创建API秘钥https://console.cloud.tencent.com/cam/capi

点击继续使用，点击 新建秘钥

然后进入https://console.cloud.tencent.com/api/explorer?Product=sms&Version=2019-07-11&Action=SendSms&SignVersion=

获取代码（以下是我修改后的代码，你只需要修改第17行和第27行的内容）

package top.bigking.backstage.utils;

import com.tencentcloudapi.common.Credential;
import com.tencentcloudapi.common.profile.ClientProfile;
import com.tencentcloudapi.common.profile.HttpProfile;
import com.tencentcloudapi.common.exception.TencentCloudSDKException;

import com.tencentcloudapi.sms.v20190711.SmsClient;

import com.tencentcloudapi.sms.v20190711.models.SendSmsRequest;
import com.tencentcloudapi.sms.v20190711.models.SendSmsResponse;

public class TencentSendSms {
    public static void sendSms(String phoneNum, String code) {
        try {

            Credential cred = new Credential("【SecreId】", "【secreKey】");

            HttpProfile httpProfile = new HttpProfile();
            httpProfile.setEndpoint("sms.tencentcloudapi.com");

            ClientProfile clientProfile = new ClientProfile();
            clientProfile.setHttpProfile(httpProfile);

            SmsClient client = new SmsClient(cred, "ap-beijing", clientProfile);

            String params = "{"PhoneNumberSet":["+86" + phoneNum + ""],"TemplateID":"【TemplateID】", "Sign":"【Sign】", "TemplateParamSet":[""+ code +""],"SmsSdkAppid":"【SmsSdkAppid】"}";
            SendSmsRequest req = SendSmsRequest.fromJsonString(params, SendSmsRequest.class);

            SendSmsResponse resp = client.SendSms(req);

            System.out.println(SendSmsRequest.toJsonString(resp));
        } catch (TencentCloudSDKException e) {
            System.out.println(e.toString());
        }

    }
}

这里其实是有坑的，比如Sign项，它是选填项，可是却必须要填。具体出现的其他问题，建议你通过返回的错误码进行排查。

该页面的第六项即为错误码：https://cloud.tencent.com/document/product/382/38778

部分截图如下：

然后你会发现红色报错，这时需要添加pom依赖：

        <dependency>
            <groupId>com.tencentcloudapi</groupId>
            <artifactId>tencentcloud-sdk-java</artifactId>
            <version>3.1.27</version><!-- 注：这里只是示例版本号，请到 https://mvnrepository.com/artifact/com.tencentcloudapi/tencentcloud-sdk-java 获取最新版本号 -->
        </dependency>

然后你就可以使用啦。

建议放入工具package中，传入手机号和验证码，方法设置为静态。 

Spring Boot结合Redis使用验证码接口的代码为：

package top.bigking.backstage.service.impl;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.stereotype.Service;
import top.bigking.backstage.service.VerifyCodeService;
import top.bigking.backstage.utils.SendSms;

import javax.annotation.Resource;
import java.util.Random;
import java.util.concurrent.TimeUnit;

/**

@Service
public class VerifyCodeServiceImpl implements VerifyCodeService {
    @Resource
    private RedisTemplate<String, String> redisTemplate;

    @Override
    public Boolean setVerifyCode(String phoneNum) {
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        String codeKey = "Verify_code:" + phoneNum + ":code";
        String codeCount = "Verify_code:" + phoneNum + ":count";
        String code = getCode(6);
        SendSms.sendSms(phoneNum, code);
        //一个号码一天最多发送三次验证码
        String count = redisTemplate.opsForValue().get(codeCount);
        if(count == null) {
            redisTemplate.opsForValue().set(codeCount, "1", 1, TimeUnit.DAYS);
            //验证码60秒过期
            redisTemplate.opsForValue().set(codeKey, code, 60, TimeUnit.SECONDS);
            return true;
        }else if(Integer.parseInt(count) <= 2){
            redisTemplate.opsForValue().set(codeCount, String.valueOf(Integer.parseInt(count) + 1), 1, TimeUnit.DAYS);
            //验证码60秒过期
            redisTemplate.opsForValue().set(codeKey, code, 60, TimeUnit.SECONDS);
            return true;
        }
        return false;
    }
    private String getCode(Integer length){
        String code = "";
        Random random = new Random();
        for (int i = 0; i < length; i++) {
            //设置了bound参数后，取值范围为[0, bound)，如果不写参数，则取值为int范围，-2^31 ~ 2^31-1
            code += random.nextInt(10);
        }
        return code;
    }

    @Override
    public String getVerifyCode(String phoneNum) {
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        String codeKey = "Verify_code:" + phoneNum + ":code";
        return redisTemplate.opsForValue().get(codeKey);
    }

}
