Java+阿里云手机验证【悟空教程】
Java+阿里云手机验证码发送和验证
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;
}
}
Redis的工具类
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.alibaba.fastjson.JSON;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

private static Jedis jedis = null;
public static Jedis jedis_object = null;
private static String host = "127.0.0.1";
// private static String password = "";
private static Integer port = 6379;
static{
if(jedisPool == null){
JedisPoolConfig config = new JedisPoolConfig();
//设置最大连接数
config.setMaxTotal(500);
//设置最大空闲数
config.setMaxIdle(20);
//设置最小空闲数
config.setMinIdle(8);
//设置超时时间
config.setMaxWaitMillis(3000);
//Idle时进行连接扫描
config.setTestWhileIdle(true);
//表示idle object evitor两次扫描之间要sleep的毫秒数
config.setTimeBetweenEvictionRunsMillis(30000);
//表示idle object evitor每次扫描的最多的对象数
config.setNumTestsPerEvictionRun(10);
//表示一个对象至少停留在idle状态的最短时间，然后才能被idle object evitor
//扫描并驱逐；这一项只有在timeBetweenEvictionRunsMillis大于0时才有意义
config.setMinEvictableIdleTimeMillis(60000);
//初始化连接池
jedisPool = new JedisPool(config, host, port);
jedis_object = new Jedis( host, port);
}
}
private RedisClientServer() {
}
private static Jedis getJedisInstance(){
try {
if(null == jedis){
jedis = jedisPool.getResource();
// jedis.auth(password);
}
} catch (Exception e) {
logger.error("实例化jedis失败.........", e);
}
return jedis;
}
/**

*/
public static boolean set(String key, String value,Integer seconds) throws Exception {
Jedis jedis = null;
try {

jedis.set(key, value);
jedis.expire(key, seconds);
return true;
} catch (Exception e) {
logger.error("redis set方法失败...key="+key+" value="+value, e);
} finally {
jedisPool.close();
}
return false;
}
/**

*/
public static Object get(String key) {
Jedis jedis = null;
try {

return value;
} catch (Exception e) {

} finally {
jedisPool.close();
}
return null;
}
/**

*/
public static boolean del(String key) {

jedis.del(key);
return true;
} catch (Exception e) {

public static Boolean exists(String key){
Jedis jedis = null;
try {
jedis = getJedisInstance();
return jedis.exists(key);
} catch (Exception e) {
e.printStackTrace();
return false;
}finally {
jedisPool.close();
}
}
}
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;
}
}
