实现短信验证微服务

大致的业务：通过rabbitmq，接收消息异步发送验证短信（非常简单）

工具：IEDA，springCloud、rabbitmq、阿里云鼎信短信API

实现（很简单）：

创建发送短信的微服务

在调用端将消息发送给交换机（调用端，不是短信微服务端）

@Override
    public void sendCode(String phone) {
        HashMap<String, Object> map = new HashMap<>();
        map.put("phone",phone);
        map.put("function","验证身份");
        map.put("code", new Random().nextInt(8000)+1000);
        try {
            amqpTemplate.convertAndSend("GMALL-SEND-EXCHANGE","send.code",map);
        } catch (AmqpException e) {
            e.printStackTrace();
        }
    }

接收端，接收消息（发送短信的微服务）

package com.atguigu.gmall.send.listener;

import com.atguigu.gmall.send.utils.HttpUtils;
import org.apache.http.HttpResponse;
import org.springframework.amqp.core.ExchangeTypes;
import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;

@Component
public class UmsListener {

    
    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = "GMALL-SEND-QUEUE",durable = "true"),
            exchange = @Exchange(value = "GMALL-SEND-EXCHANGE",ignoreDeclarationExceptions = "true",type = ExchangeTypes.TOPIC),
            key = {"send.code"}
   ))
    public void sendCode(Map<String,Object>map){

        String host = "http://dingxin.market.alicloudapi.com";
        String path = "/dx/sendSms";
        String method = "POST";
        String appcode = "ec6ff90cbd07*****159746b157";
        Map<String, String> headers = new HashMap<String, String>();
        //最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105
        headers.put("Authorization", "APPCODE " + appcode);
        Map<String, String> querys = new HashMap<String, String>();
        querys.put("mobile", map.get("phone").toString());
        querys.put("param", "code:"+map.get("code").toString());
        querys.put("tpl_id", "TP1711063");
        Map<String, String> bodys = new HashMap<String, String>();
        try {
            /**
             * 重要提示如下:

            HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);
            System.out.println(response.toString());
            //获取response的body
            //System.out.println(EntityUtils.toString(response.getEntity()));
        } catch (Exception e) {
            e.printStackTrace();
        }

        System.out.println(map.get("code"));
    }

}

具体的工具类，看官方的API下载使用

application.yml配置文件（两个微服务都必须写，调用端和别调用端）

  rabbitmq:
    virtual-host: /theking #虚拟主机名称以/开头
    host: 192.168.232.128  #地址
    username: theking      #用户名
    password: 1217         #密码
