本文主要是介绍后端实现微信小程序发送订阅消息模板,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

需要access_token,appid,secret,订阅者的openid,template_id(模板ID)

package com.xxxy.tower.service.impl;

import com.xxxy.tower.dto.AccessTokenInfo;
import com.xxxy.tower.service.WxSubscribeService;
import com.xxxy.tower.util.HttpClientUtil;
import com.xxxy.tower.util.JsonUtils;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.HashMap;
import java.util.Map;


@Slf4j
public class WxSubscribeService {

    public boolean sendMsg() {

        String accessToken = getAccessToken();
        String openId = user.getOpenId();
        String templateId = "qxz3pJIwAZaw8zGOiYRp_mw90UHUMfEJDMw8mkpfVGA";

        Map<String, Object> params = new HashMap<>();
        Map<String, Object> data = new HashMap<>();

        params.put("touser", openId);
        params.put("template_id", templateId);

        //设备编号
        data.put("character_string1", getDataMap("设备编号"));
        //报警类别
        data.put("thing3", getDataMap("报警类别"));
        //报警地点
        data.put("thing7", getDataMap("报警地点"));
        //报警内容
        data.put("thing19", getDataMap("报警内容"));
//        log.info();
        params.put("data", data);


        String json = JsonUtils.objectToJson(params);
        log.info(json);

        String url = "https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=" + accessToken;
        String response = HttpClientUtil.doPostJson(url, json);
        log.info(response);
        return true;
    }


    public static String getAccessToken(){

        String grant_type="client_credential";
        //封装请求数据
        Map<String, String> params = new HashMap<>();
        params.put("grant_type", grant_type);
        params.put("appid", "xxxxxxxxxxxx");
        params.put("secret", "xxxxxxxxxxxxxxxxxxxxx");

        //发送GET请求
        String url = "https://api.weixin.qq.com/cgi-bin/token";
        String response = HttpClientUtil.doGet(url, params);
        //拿到accessToken
        try {
            AccessTokenInfo accessTokenInfo = JsonUtils.jsonToPojo(response, AccessTokenInfo.class);
            return accessTokenInfo.getAccess_token();
        }catch (Exception e) {
            return null;
        }
    }

    public static Map<String, String> getDataMap(String msg){
        Map<String, String> map = new HashMap<>();
        map.put("value", msg);
        return map;
    }


}
