第01章-短信发送
1、云市场-短信API
1.1、开通三网106短信
在阿里云云市场搜索“短信”，一般都可用，选择一个即可，例如如下：点击“立即购买”开通
这里开通的是【短信验证码- 快速报备签名】
1.2、获取开发参数
登录云市场控制台，在已购买的服务中可以查看到所有购买成功的API商品情况，下图红框中的就是AppKey/AppSecret，AppCode的信息。
1.3、API方式使用云市场服务
将工具类放入service-yun微服务的utils包中：资料：资料>短信发送>工具类
参考如下例子，复制代码在test目录进行测试
2、发送短息
2.1、Controller
创建FrontSmsController
package com.atguigu.syt.yun.controller.front;
@Api(tags = "短信接口")
@RestController
@RequestMapping("/front/yun/sms")
public class FrontSmsController {
@Resource
private SmsService smsService;
@Resource
private RedisTemplate redisTemplate;
@ApiOperation("发送短信")
@ApiImplicitParam(name = "phone",value = "手机号")
@PostMapping("/send/{phone}")
public Result send(@PathVariable String phone) {
//生成验证码
int minutes = 5; //验证码5分钟有效
String code = RandomUtil.getFourBitRandom();
//创建短信发送对象
SmsVo smsVo = new SmsVo();
smsVo.setPhone(phone);
smsVo.setTemplateCode("CST_qozfh101");
Map<String,Object> paramsMap = new HashMap<String, Object>(){{
put("code", code);
put("expire_at", 5);
}};
smsVo.setParam(paramsMap);
//发送短信
smsService.send(smsVo);
//验证码存入redis
redisTemplate.opsForValue().set("code:" + phone, code, minutes, TimeUnit.MINUTES);
return Result.ok().message("短信发送成功");
}
}
2.2、Service
接口：SmsService
package com.atguigu.syt.yun.service;
public interface SmsService {
/**
* 发送短信
* @param smsVo
*/
void send(SmsVo smsVo);
}
实现：SmsServiceImpl
package com.atguigu.syt.yun.service.impl;
@Service
@Slf4j
public class SmsServiceImpl implements SmsService {
@Override
public void send(SmsVo smsVo) {
String host = "https://dfsns.market.alicloudapi.com";
String path = "/data/send_sms";
String method = "POST";
String appcode = "你的appcode";
Map<String, String> headers = new HashMap<>();
//最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
headers.put("Authorization", "APPCODE " + appcode);
//根据API的要求，定义相对应的Content-Type
headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
Map<String, String> querys = new HashMap<>();
Map<String, String> bodys = new HashMap<>();
StringBuffer contentBuffer = new StringBuffer();
smsVo.getParam().entrySet().forEach( item -> {
contentBuffer.append(item.getKey()).append(":").append(item.getValue()).append(",");
});
String content = contentBuffer.substring(0, contentBuffer.length() - 1);
bodys.put("content", content);
bodys.put("phone_number", smsVo.getPhone());
bodys.put("template_id", smsVo.getTemplateCode());
try {
/**
* 重要提示如下:
* HttpUtils请从
* https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/src/main/java/com/aliyun/api/gateway/demo/util/HttpUtils.java
* 下载
*
* 相应的依赖请参照
* https://github.com/aliyun/api-gateway-demo-sign-java/blob/master/pom.xml
*/
HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
//获取response的body
String data = EntityUtils.toString(response.getEntity());
HashMap<String, String> resultMap = JSONObject.parseObject(data, HashMap.class);
String status = resultMap.get("status");
if(!"OK".equals(status)){
String reason = resultMap.get("reason");
log.error("短信发送失败：status = " + status + ", reason = " + reason);
throw new GuiguException(ResultCodeEnum.FAIL.getCode(), "短信发送失败");
}
} catch (Exception e) {
log.error(ExceptionUtils.getStackTrace(e));
throw new GuiguException(ResultCodeEnum.FAIL.getCode(), "短信发送失败");
}
}
}
3、绑定手机号
3.1、Controller
service-user微服务FrontUserInfoController中添加接口方法
@ApiOperation("绑定手机号")
@ApiImplicitParams({
@ApiImplicitParam(name = "phone",value = "手机号", required = true),
@ApiImplicitParam(name = "code",value = "验证码", required = true)})
@PostMapping("/auth/bindPhone/{phone}/{code}")
public Result bindPhone(@PathVariable String phone, @PathVariable String code, HttpServletRequest request, HttpServletResponse response) {
Long userId = authContextHolder.checkAuth(request, resposne);
userInfoService.bindPhone(userId, phone, code);
return Result.ok().message("绑定成功");
}
3.2、Service
接口：UserInfoService
/**
* 绑定当前用户的手机号
* @param userId
* @param phone
* @param code
*/
void bindPhone(Long userId, String phone, String code);
实现：UserInfoServiceImpl
@Resource
private RedisTemplate redisTemplate;
@Override
public void bindPhone(Long userId, String phone, String code) {
//校验参数
if(StringUtils.isEmpty(phone) || StringUtils.isEmpty(code)) {
throw new GuiguException(ResultCodeEnum.PARAM_ERROR);
}
//校验验证码
String phoneCode = (String)redisTemplate.opsForValue().get("code:" + phone);
if(!code.equals(phoneCode)) {
throw new GuiguException(ResultCodeEnum.CODE_ERROR);
}
//根据手机号查找会员
LambdaQueryWrapper<UserInfo> queryWrapper = new LambdaQueryWrapper<>();
//手机号没有被其他人绑定过
queryWrapper.eq(UserInfo::getPhone, phone).ne(UserInfo::getId, userId);
UserInfo userInfo = baseMapper.selectOne(queryWrapper);
//手机号已存在
if(userInfo != null) {
throw new GuiguException(ResultCodeEnum.REGISTER_MOBILE_ERROR);
}
//设置绑定手机号
userInfo = new UserInfo();
userInfo.setId(userId);
userInfo.setPhone(phone);
baseMapper.updateById(userInfo);
}
4、前端整合
4.1、api
创建sms.js
import request from '~/utils/request'
export default {
sendCode(phone) {
return request({
url: `/front/yun/sms/send/${phone}`,
method: `post`
})
}
}
在userInfo.js中添加方法
bindPhone(phone, code) {
return request({
url: `/front/user/userInfo/auth/bindPhone/${phone}/${code}`,
method: `post`
})
},
4.2、页面组件
复制页面到项目pages目录中
资料：资料>手机号绑定页面
第02章-引入MQ
预约或取消预约成功后我们要 更新预约数 以及 发送短信提醒，为了实现用户下单和取消订单的快速响应，这部分逻辑我们就交给MQ完成。
1、引入RabbitMQ
1.1、安装RabbitMQ
#拉取镜像
docker pull rabbitmq:3.8-management
#创建容器启动
docker run -d --restart=always -p 5672:5672 -p 15672:15672 --name rabbitmq rabbitmq:3.8-management
1.2、访问管理后台
登录：guest / guest
1.3、创建rabbit-utils模块
在common模块中创建rabbit-utils模块
1.4、引入依赖
在rabbit-utils中引入依赖
<dependencies>
<!--rabbitmq消息队列-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
</dependencies>
1.5、创建RabbitService类
添加sendMessage方法
package com.atguigu.syt.rabbit;
@Service
@Slf4j
public class RabbitService {
@Resource
private RabbitTemplate rabbitTemplate;
/**
* 发送消息
* @param exchange 交换机
* @param routingKey 路由
* @param message 消息
*/
public boolean sendMessage(String exchange, String routingKey, Object message) {
log.info("发送消息...........");
rabbitTemplate.convertAndSend(exchange, routingKey, message);
return true;
}
}
1.6、配置MQ消息转换器
package com.atguigu.syt.rabbit.config;
@Configuration
public class MQConfig {
@Bean
public MessageConverter messageConverter(){
//配置json字符串转换器，默认使用SimpleMessageConverter
return new Jackson2JsonMessageConverter();
}
}
1.7、添加常量类
package com.atguigu.syt.rabbit.config;
public class MQConst {
/**
* 预约/取消订单
*/
public static final String EXCHANGE_DIRECT_ORDER = "exchange.direct.order";
public static final String ROUTING_ORDER = "routing.order";
public static final String QUEUE_ORDER = "queue.order";
/**
* 短信
*/
public static final String EXCHANGE_DIRECT_SMS = "exchange.direct.sms";
public static final String ROUTING_SMS = "routing.sms";
public static final String QUEUE_SMS = "queue.sms";
}
2、service-yun中发送短信
2.1、引入依赖
<!--MQ-->
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>rabbit-utils</artifactId>
<version>1.0</version>
</dependency>
2.2、添加MQ配置
spring:
rabbitmq:
host: 192.168.100.101
port: 5672
username: guest
password: guest
2.3、封装MQ监听器
在监听器中发送短信：
package com.atguigu.syt.yun.receiver;
@Component
@Slf4j
public class SmsReceiver {
@Resource
private SmsService smsService;
/**
* 监听MQ中的消息
* @param smsVo
*/
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = MQConst.QUEUE_SMS, durable = "true"), //消息队列，并持久化
exchange = @Exchange(value = MQConst.EXCHANGE_DIRECT_SMS), //交换机
key = {MQConst.ROUTING_SMS} //路由
))
public void receive(SmsVo smsVo){
log.info("SmsReceiver 监听器监听到消息......");
smsService.send(smsVo);
}
}
3、service-hosp中更新排班数量
3.1、引入依赖
<!--MQ-->
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>rabbit-utils</artifactId>
<version>1.0</version>
</dependency>
3.2、添加MQ配置
spring:
rabbitmq:
host: 192.168.100.101
port: 5672
username: guest
password: guest
3.3、封装MQ监听器
在监听器中更新排班数量：
package com.atguigu.syt.hosp.receiver;
@Component
@Slf4j
public class HospReceiver {
@Resource
private ScheduleService scheduleService;
/**
* 监听MQ中的消息
* @param orderMqVo
*/
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = MQConst.QUEUE_ORDER, durable = "true"), //消息队列，并持久化
exchange = @Exchange(value = MQConst.EXCHANGE_DIRECT_ORDER), //交换机
key = {MQConst.ROUTING_ORDER} //路由
))
public void receive(OrderMqVo orderMqVo){
//修改排班信息
log.info("HospReceiver 监听器监听到消息......");
scheduleService.updateByOrderMqVo(orderMqVo);
}
}
接口：ScheduleService
/**
* 更新排班数量
* @param orderMqVo
*/
void updateByOrderMqVo(OrderMqVo orderMqVo);
实现：ScheduleServiceImpl
@Override
public void updateByOrderMqVo(OrderMqVo orderMqVo) {
//下单成功更新预约数
ObjectId objectId = new ObjectId(orderMqVo.getScheduleId());
//id是objectId
Schedule schedule = scheduleRepository.findById(objectId).get();
//id是string
// Schedule schedule = scheduleRepository.findById(orderMqVo.getScheduleId()).get();
schedule.setReservedNumber(orderMqVo.getReservedNumber());
schedule.setAvailableNumber(orderMqVo.getAvailableNumber());
//主键一致就是更新
scheduleRepository.save(schedule);
}
4、完善service-orde订单接口
4.1、引入依赖
<!--MQ-->
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>rabbit-utils</artifactId>
<version>1.0</version>
</dependency>
4.2、添加MQ配置
spring:
rabbitmq:
host: 192.168.100.101
port: 5672
username: guest
password: guest
4.3、修改下单方法
OrderInfoServiceImpl类：
@Resource
private RabbitService rabbitService;
submitOrder方法中添加发送消息的业务逻辑：
//使用这两个数据更新平台端的最新的排班数量
Integer reservedNumber = data.getInteger("reservedNumber");
Integer availableNumber = data.getInteger("availableNumber");
//目的1：更新mongodb数据库中的排班数量
//组装数据同步消息对象
OrderMqVo orderMqVo = new OrderMqVo();
orderMqVo.setAvailableNumber(availableNumber);
orderMqVo.setReservedNumber(reservedNumber);
orderMqVo.setScheduleId(scheduleId);
//发消息
rabbitService.sendMessage(MQConst.EXCHANGE_DIRECT_ORDER, MQConst.ROUTING_ORDER, orderMqVo);
//目的2：给就诊人发短信
//组装短信消息对象
SmsVo smsVo = new SmsVo();
smsVo.setPhone(orderInfo.getPatientPhone());
//亲爱的用户：您已预约%{hosname}%{hosdepname}%{date}就诊
//请您于%{time}至%{address}取号，
//您的就诊号码是%{number}，请您及时就诊
smsVo.setTemplateCode("和客服申请模板编号");
Map<String,Object> paramsSms = new HashMap<String, Object>(){{
put("hosname", orderInfo.getHosname());
put("hosdepname", orderInfo.getDepname());
put("date", new DateTime(orderInfo.getReserveDate()).toString("yyyy-MM-dd"));
put("time", orderInfo.getFetchTime());
put("address", orderInfo.getFetchAddress());
put("number", orderInfo.getNumber());
}};
smsVo.setParam(paramsSms);
//向MQ发消息
rabbitService.sendMessage(MQConst.EXCHANGE_DIRECT_SMS, MQConst.ROUTING_SMS, smsVo);
4.4、修改取消订单方法
cancelOrder方法中添加发送消息的业务逻辑：
//获取返回数据
JSONObject jsonObject = jsonResult.getJSONObject("data");
Integer reservedNumber = jsonObject.getInteger("reservedNumber");
Integer availableNumber = jsonObject.getInteger("availableNumber");
//目的1：更新mongodb数据库中的排班数量
//组装数据同步消息对象
OrderMqVo orderMqVo = new OrderMqVo();
orderMqVo.setAvailableNumber(availableNumber);
orderMqVo.setReservedNumber(reservedNumber);
orderMqVo.setScheduleId(orderInfo.getScheduleId());
//发消息
rabbitService.sendMessage(MQConst.EXCHANGE_DIRECT_ORDER, MQConst.ROUTING_ORDER, orderMqVo);
//目的2：给就诊人发短信
//组装短信消息对象
SmsVo smsVo = new SmsVo();
smsVo.setPhone(orderInfo.getPatientPhone());
//亲爱的用户：您已取消%{hosname}%{hosdepname}%{date}就诊
smsVo.setTemplateCode("和客服申请模板编号");
Map<String,Object> paramsSms = new HashMap<String, Object>(){{
put("hosname", orderInfo.getHosname());
put("hosdepname", orderInfo.getDepname());
put("date", new DateTime(orderInfo.getReserveDate()).toString("yyyy-MM-dd"));
}};
smsVo.setParam(paramsSms);
//向MQ发消息
rabbitService.sendMessage(MQConst.EXCHANGE_DIRECT_SMS, MQConst.ROUTING_SMS, smsVo);
5、就诊人提醒
5.1、添加定时任务
在service-order微服务中添加定时任务：创建ScheduledTask类
cron表达式参考：https://qqe2.com/cron
package com.atguigu.syt.order.schedule;
@Component
@EnableScheduling //开启定时任务
@Slf4j
public class ScheduledTask {
/**
* 测试
* (cron="秒 分 时 日 月 周")
* *：每隔一秒执行
* 0/3：从第0秒开始，每隔3秒执行一次
* 1-3: 从第1秒开始执行，到第3秒结束执行
* 1,2,3：第1、2、3秒执行
* ?：不指定，若指定日期，则不指定周，反之同理
*/
@Scheduled(cron="0/3 * * * * ?")
public void task1() {
log.info("task1 执行");
}
}
5.2、添加就诊人提醒定时任务
@Resource
private OrderInfoService orderInfoService;
@Scheduled(cron = "0 0 18 * * ?")
public void patientAdviceTask(){
log.info("执行定时任务");
orderInfoService.patientAdvice();
}
5.3、Service
需求：就诊前一天晚六点向用户发送就医提醒短信
接口：OrderInfoService
/**
* 就诊人提醒
*/
void patientAdvice();
实现：OrderInfoServiceImpl
@Override
public void patientAdvice() {
//查询明天的预约信息
LambdaQueryWrapper<OrderInfo> queryWrapper = new LambdaQueryWrapper<>();
//明天
String tomorrow = new DateTime().plusDays(1).toString("yyyy-MM-dd");
queryWrapper.eq(OrderInfo::getReserveDate, tomorrow);
//未取消
queryWrapper.ne(OrderInfo::getOrderStatus, OrderStatusEnum.CANCLE.getStatus());
List<OrderInfo> orderInfoList = baseMapper.selectList(queryWrapper);
for (OrderInfo orderInfo : orderInfoList) {
//短信对象
SmsVo smsVo = new SmsVo();
smsVo.setPhone(orderInfo.getPatientPhone());
//就诊提醒：您已预约%{hosname}%{depname}的号源，就诊时间：%{date}，就诊人%{name}，请您合理安排出行时间
smsVo.setTemplateCode("和客服申请模板编号");
Map<String,Object> paramsSms = new HashMap<String, Object>(){{
put("hosname", orderInfo.getHosname());
put("hosdepname", orderInfo.getDepname());
put("date", new DateTime(orderInfo.getReserveDate()).toString("yyyy-MM-dd"));
put("name", orderInfo.getPatientName());
}};
smsVo.setParam(paramsSms);
//发消息
rabbitService.sendMessage(MQConst.EXCHANGE_DIRECT_SMS, MQConst.ROUTING_SMS, smsVo);
}
}
