1.注册流程分析
- 客户端先发送一个手机号码到后端获取验证码，此时“获取验证码”按钮是激活状态，“下一步”按钮是禁用状态
点击“获取验证码”按钮，该按钮60秒倒计时变为禁用状态，等待用户接收验证码并输入 - 后端根据这个手机号先到数据库查询该手机号是否已被注册，如果已经被注册就返回“该手机号已被注册”，不继续后续步骤
- 如果没被注册，后端为该手机号生成一个随机6位验证码存在Redis中（指定时限），然后将该验证码通过阿里云的短信服务接口发送给客户端
- 客户端收到短信，输入验证码，点击下一步后端收到客户端发送的验证码，就将其和Redis中暂存的验证码比对，如果一致就放行，否则提示“验证码错误”
- 验证码正确，进入填写密码的页面，填写完毕提交到后端，加密存入数据库，注册成功，让用户选择去登录，还是回到首页
2.Redis准备
GitHub下载
- 解压后放入本地目录
- 运行运行redis-server
cd D:\tools\redis
redis-server.exe redis.windows.conf

-
再开一个命令行窗口，进入redis目录，运行redis-cli.exe命令，进行一下基本操作
set是设置键值对，keys是列出所有键，get是获取指定键的值，del是删除指定的键值

3. 阿里云短信服务
短信服务
API文档
- demo程序，注意修改其中***的内容为自己的
package com.soft1721.jianyue.api.util;
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
/**
* 短消息测试程序
*/
public class SMSTest {
public static void main(String[] args) {
DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "*******", "*****");
IAcsClient client = new DefaultAcsClient(profile);
CommonRequest request = new CommonRequest();
request.setMethod(MethodType.POST);
request.setDomain("dysmsapi.aliyuncs.com");
request.setVersion("2017-05-25");
request.setAction("SendSms");
request.putQueryParameter("RegionId", "cn-hangzhou");
request.putQueryParameter("PhoneNumbers", "****");
request.putQueryParameter("SignName", "****");
request.putQueryParameter("TemplateCode", "SMS_135805735");
request.putQueryParameter("TemplateParam", "{\"code\":\"888888\"}");
try {
CommonResponse response = client.getCommonResponse(request);
System.out.println(response.getData());
} catch (ServerException e) {
e.printStackTrace();
} catch (ClientException e) {
e.printStackTrace();
}
}
}
4.后端
- pom.xml，增加阿里云短信服务SDK依赖和SpringBoot集成redis依赖
com.aliyun
aliyun-java-sdk-core
4.0.3
org.springframework.boot
spring-boot-starter-data-redis
- util包的StringUtil类增加一个方法，用来获取六位随机数验证码
public static String getVerifyCode() {
Random random = new Random();
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < 6; i++) {
stringBuilder.append(String.valueOf(random.nextInt(10)));
}
return stringBuilder.toString();
}
- 编写SMSUtil短信发送工具类，主要将手机号和短信字符串分离成变量，main方法测试通过后即可删除
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
/**
* 短信发送工具类，返回生成的随机验证码
*/
public class SMSUtil {
public static String send(String mobile) {
DefaultProfile profile = DefaultProfile.getProfile(
"cn-hangzhou",
"*******",
"*******");
IAcsClient client = new DefaultAcsClient(profile);
CommonRequest request = new CommonRequest();
request.setMethod(MethodType.POST);
request.setDomain("dysmsapi.aliyuncs.com");
request.setVersion("2017-05-25");
request.setAction("SendSms");
request.putQueryParameter("RegionId", "cn-hangzhou");
request.putQueryParameter("PhoneNumbers", mobile);
request.putQueryParameter("SignName", "*****");
request.putQueryParameter("TemplateCode", "SMS_135805735");
String verifyCode = StringUtil.getVerifyCode();
request.putQueryParameter("TemplateParam", "{\"code\":" + verifyCode + "}");
try {
CommonResponse response = client.getCommonResponse(request);
System.out.println(response.getData());
} catch (ServerException e) {
e.printStackTrace();
} catch (ClientException e) {
e.printStackTrace();
}
return verifyCode;
}
public static void main(String[] args) {
System.out.println(send("139****1489"));
}
}
- mapper层增加insertUser方法，自行实现（id和token不用给值）
- service接口增加注册方法
void signUp(UserDTO userDTO);
- signUp方法实现代码
@Override
public void signUp(UserDTO userDTO) {
User user1 = new User();
user1.setMobile(userDTO.getMobile());
user1.setPassword(StringUtil.getBase64Encoder(userDTO.getPassword()));
user1.setNickname("新用户");
user1.setAvatar("http://ppeto2k90.bkt.clouddn.com/avatar/default.png");
user1.setRegtime(new Date());
user1.setStatus((short) 1);
userMapper.insert(user1);
}
- 单元测试
@Test
public void signUp() {
UserDTO userDTO = new UserDTO();
userDTO.setMobile("139****1489");
userDTO.setPassword("111");
userService.signUp(userDTO);
}
- controller层编写前，先到StatusConst和MsgConst添加需要用到的常量
public static final int MOBILE_EXIST = 5;
public static final int VERIFYCODE_ERROR = 6;
public static final String MOBILE_EXIST = "手机号已被注册";
public static final Str
ing VERIFYCODE_ERROR = "验证码错误";
- 获取短信验证码接口
@PostMapping(value = "/verify")
public ResponseResult getVerifyCode(@RequestParam("mobile") String mobile) {
User user = userService.getUserByMobile(mobile);
//手机号已经被注册
if (user != null) {
return ResponseResult.error(StatusConst.MOBILE_EXIST, MsgConst.MOBILE_EXIST);
} else {
//发送验证码
String verifyCode = SMSUtil.send(mobile);
// String verifyCode = StringUtil.getVerifyCode();
System.out.println(verifyCode);
//手机号和验证码作为键值对存入redis中
redisService.set(mobile, verifyCode);
return ResponseResult.success();
}
}
- 验证短信码接口
@PostMapping(value = "/check")
public ResponseResult checkVerifyCode(@RequestParam("mobile") String mobile, @RequestParam("verifyCode") String verifyCode) {
//从Redis中取出这个手机号的验证码
String code = redisService.get(mobile).toString();
//System.out.println(code + "---");
// System.out.println(verifyCode);
//和客户端传过来的验证码比对
if (code.equals(verifyCode)) {
return ResponseResult.success();
} else {
return ResponseResult.error(StatusConst.VERIFYCODE_ERROR, MsgConst.VERIFYCODE_ERROR);
}
}
- 注册接口
public ResponseResult signUp(@RequestBody UserDTO userDTO) {
userService.signUp(userDTO);
return ResponseResult.success();
}
