Java+阿里云手机验证码发送和验证

Java+阿里云手机验证码发送和验证

作者：阳旭网络

技术依赖：spring boot 技能掌握：java，spring boot框架，redis

文章简介：通过接入阿里云的短信服务的发送验证的接口，实现验证码的发送。
一、准备阶段
1.1spring boot的项目的搭建
1.2准备接入接口的资料
参考阿里云的官方文档：https://help.aliyun.com/document_detail/55284.html?spm=a2c4g.11186623.6.557.2lq7AO
必须完成的步骤：
（1）进入阿里云服务台->服务与产品—>短信服务；
（2）接口调用中获取AccessKey（必须）；
（3）签名管理中，添加一个签名，最好是自己账号的用户名，否则容易审核不通过；记录签名名称；
（4）模板管理中，添加一个短信模板，记录模板Code
二、Java代码
可以下载阿里官方提供的代码。下面是我使用的代码，仅供参考。
2.1 导入所需要的jar包

  <dependency>
   <groupId>com.aliyun</groupId>
   <artifactId>aliyun-java-sdk-core</artifactId>
   <version>4.0.0</version>
</dependency>
<dependency>
   <groupId>com.aliyun</groupId>
   <artifactId>aliyun-java-sdk-dysmsapi</artifactId>
   <version>1.1.0</version>
</dependency>
<!-- Spring Boot Redis依赖 -->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-redis</artifactId>
   <!-- 1.5的版本默认采用的连接池技术是jedis  
        2.0以上版本默认连接池是lettuce, 在这里采用jedis，
        所以需要排除lettuce的jar -->
   <exclusions>
      <exclusion>
         <groupId>redis.clients</groupId>
         <artifactId>jedis</artifactId>
      </exclusion>
      <exclusion>
         <groupId>io.lettuce</groupId>
         <artifactId>lettuce-core</artifactId>
      </exclusion>
   </exclusions>
</dependency>

<!-- 添加jedis客户端 -->
<dependency>
   <groupId>redis.clients</groupId>
   <artifactId>jedis</artifactId>
</dependency>

<!--spring2.0集成redis所需common-pool2-->
<!-- 必须加上，jedis依赖此  -->
<dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-pool2</artifactId>
   <version>2.5.0</version>
</dependency>  

2.2 要发送手机验证的接口PhoneController.java

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsRequest;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import com.yx.open.util.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.util.Map;

@RestController
@SpringBootApplication
@CrossOrigin(origins = "*", maxAge = 3600)//解决跨域的请求
@RequestMapping(value = "/api/code")
public class PhoneCodeController {

    //短信API产品名称（短信产品名固定，无需修改）
    static private final String product = "Dysmsapi";
    //短信API产品域名（接口地址固定，无需修改）
    static private final String domain = "dysmsapi.aliyuncs.com";

    static private final String accessKeyId = "";
    static private final String accessKeySecret = "";

    @RequestMapping(value = "/phoneCode", method = RequestMethod.POST)
    @ResponseBody
    public string sendCode(HttpServletRequest req) throws ClientException {

        //设置超时时间-可自行调整
        System.setProperty("sun.net.client.defaultConnectTimeout", "60000");
        System.setProperty("sun.net.client.defaultReadTimeout", "60000");

        String userPhone = req.getParameter()("userPhone");

        //验证码code
        String code = RandomCode.getRandomNumCode(4);
        //短信签名
        String signName = "";//写你自己申请的签名名称
        //短信模板
        String templateCode = "";//短信模板的CODE

        //初始化ascClient,暂时不支持多region（请勿修改）
        IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", accessKeyId,accessKeySecret);
        DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou", product, domain);
        IAcsClient acsClient = new DefaultAcsClient(profile);

        //组装请求对象
        SendSmsRequest request = new SendSmsRequest();

        request.setPhoneNumbers(userPhone);
        request.setSignName(signName);
        request.setTemplateCode(templateCode);
        request.setTemplateParam("{\"name\":\""+userPhone+"\", \"code\":\""+code+"\"}");

        //请求失败这里会抛ClientException异常
        SendSmsResponse sendSmsResponse = acsClient.getAcsResponse(request);
        if(sendSmsResponse.getCode() != null && sendSmsResponse.getCode().equals("OK")) {

            try {
                RedisClientServer.set("code"+userPhone,code,600);
            }catch (Exception e){
                e.printStackTrace();
                return "";
            }

            return "success";
        }else {
            return null;
        }
}

2.3 生成随机数字和redis的工具类

RandomCode.java


import java.util.Random;

public class RandomCode {
    /**
     * 生成数字验证码
     * @param number
     * @return
     */
    public static String getRandomNumCode(int number){
        String codeNum = "";
        int [] numbers = {0,1,2,3,4,5,6,7,8,9};
        Random random = new Random();
        for (int i = 0; i < number; i++) {
            //目的是产生足够随机的数，避免产生的数字重复率高的问题
            int next = random.nextInt(10000);
            codeNum+=numbers[next%10];
        }
        System.out.println(codeNum);
        return codeNum;
    }

    /**
     * 生成数字+字母的验证码
     * @param number
     * @return
     */
    public static String getRandomCode(int number){
        String codeNum = "";
        int [] code = new int[3];
        Random random = new Random();
        for (int i = 0; i < number; i++) {
            int num = random.nextInt(10) + 48;
            int uppercase = random.nextInt(26) + 65;
            int lowercase = random.nextInt(26) + 97;
            code[0] = num;
            code[1] = uppercase;
            code[2] = lowercase;
            codeNum+=(char)code[random.nextInt(3)];
        }
        System.out.println(codeNum);

        return codeNum;
    }
}

三、发送验证码及验证
写一个验证的接口

@RequestMapping(value = "/register", method = RequestMethod.GET)
@ResponseBody
public String register(HttpServletRequest request){
 try {
      String code = request.getParameter("code");

if (!code.equals(RedisClientServer.get("code"+userPhone+page))){
 return  “error”           
}
return null;
}catch (Exception e){
      throw e;
}
}
