Spring Boot + Redis使用短信平台發送驗證碼(騰訊雲短信平台)

如題。

我這里使用的是騰訊雲短信平台，理由是，首次開通贈送100條短信

在個人實名認證之后，進入https://cloud.tencent.com/act/free

根據步驟，進行模板的填寫和申請

接下來創建API秘鑰https://console.cloud.tencent.com/cam/capi

點擊繼續使用，點擊 新建秘鑰

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

獲取代碼（以下是我修改后的代碼，你只需要修改第17行和第27行的內容）

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());
        }

    }
}

這里其實是有坑的，比如Sign項，它是選填項，可是卻必須要填。具體出現的其他問題，建議你通過返回的錯誤碼進行排查。

該頁面的第六項即為錯誤碼：https://cloud.tencent.com/document/product/382/38778

部分截圖如下：

 

 

然后你會發現紅色報錯，這時需要添加pom依賴：

        <dependency>
            <groupId>com.tencentcloudapi</groupId>
            <artifactId>tencentcloud-sdk-java</artifactId>
            <version>3.1.27</version><!-- 注：這里只是示例版本號，請到 https://mvnrepository.com/artifact/com.tencentcloudapi/tencentcloud-sdk-java 獲取最新版本號 -->
        </dependency>

然后你就可以使用啦。

 

---------------------------------

建議放入工具package中，傳入手機號和驗證碼，方法設置為靜態。 

 

Spring Boot結合Redis使用驗證碼接口的代碼為：

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);
        //一個號碼一天最多發送三次驗證碼
        String count = redisTemplate.opsForValue().get(codeCount);
        if(count == null) {
            redisTemplate.opsForValue().set(codeCount, "1", 1, TimeUnit.DAYS);
            //驗證碼60秒過期
            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);
            //驗證碼60秒過期
            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++) {
            //設置了bound參數后，取值范圍為[0, bound)，如果不寫參數，則取值為int范圍，-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);
    }

}
