微信公众号推送模板消息给用户

前置条件:

1.公众号为服务号,而非订阅号

2.认证(300元)

3.进入公众号申请模板推送功能

4.添加模板(注意:推送的消息只能使用微信提供的模板,不可自定义,但也是比较全的)

4.2 获取accessToken时,需要将开发环境的电脑ip添加到微信后台的ip白名单(线上环境亦是如此)

5.编码(可以先看下接口文档)【以下为无跳转功能示例代码】

 public String test() {
        String templateId = "NtMhq-lqMiaORC4L95J_aODMzf-OhPZpD1dAgW7qvWs";
        Map<Object, WeChatTemplateMsg> sendMap = new HashMap<>();
        sendMap.put("first", new WeChatTemplateMsg("您好,有一个设备离线通知~"));
        sendMap.put("keyword1", new WeChatTemplateMsg("keyword1"));
        sendMap.put("keyword2", new WeChatTemplateMsg("keyword2"));
        sendMap.put("keyword3", new WeChatTemplateMsg("keyword3"));
        sendMap.put("keyword4", new WeChatTemplateMsg("keyword4"));
        sendMap.put("remark", new WeChatTemplateMsg("remark"));
        Map<String, Object> map = getNotifyMap("oI9SZ6Jt-myBmVhbaGxOJuglUjBY", templateId, sendMap);
        ResponseEntity<String> forEntity = restTemplate.postForEntity(NOTIFY_URL + getAccessToken(), map, String.class);
        log.error("通知管理员设备状态完成。请求参数:{},响应参数:{}", map, forEntity);
        return null;
    }

//通用通知参数封装
private Map<String, Object> getNotifyMap(String openId, String templateId, Map<Object, WeChatTemplateMsg> sendMap) {
        Map<String, Object> sendBody = new HashMap<>();
        sendBody.put("touser", openId); // openId
        sendBody.put("template_id", templateId);     // 模板Id
        sendBody.put("topcolor", "#FF0000");          // 顶色
        sendBody.put("data", sendMap);                   // 模板参数
        return sendBody;
    }

//获取token(此处加了个redis,可选择不加,每次调接口获取也可)
 public String getAccessToken() {
        String accessToken;
        //0.从redis中检索,若没有则调用接口获取
        boolean hasKey = redisOprUtil.hasKey(WX_ACCESS_TOKEN_KEY);
        if (hasKey) {
            accessToken = redisOprUtil.get(WX_ACCESS_TOKEN_KEY).toString();
            log.error("redis中获取access_token......");
        } else {
            //1.调用接口获取
            String url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" + appId + "&secret=" + appSecret;
            String resp = restTemplate.getForObject(url, String.class);
            log.error("获取token的响应:{}", resp);
            JSONObject jsonObject = JSONObject.parseObject(resp);
            accessToken = jsonObject.get("access_token").toString();
            int expiresIn = Integer.parseInt(jsonObject.get("expires_in").toString());
            //并将结果保存到redis中
            boolean saveAccessToken = redisOprUtil.set(WX_ACCESS_TOKEN_KEY, accessToken, expiresIn);

            log.error("微信接口获取access_token......且已保存到redis中:{}", saveAccessToken);
        }

        return accessToken;
    }

5.2 编码(可以先看下接口文档)【模板消息跳转到小程序】

public String test() {
        String templateId = "NtMhq-lqMiaORC4L95J_aODMzf-OhPZpD1dAgW7qvWs";
        Map<Object, WeChatTemplateMsg> sendMap = new HashMap<>();
        sendMap.put("first", new WeChatTemplateMsg("您好,有一个设备离线通知~"));
        sendMap.put("keyword1", new WeChatTemplateMsg("keyword1"));
        sendMap.put("keyword2", new WeChatTemplateMsg("keyword2"));
        sendMap.put("keyword3", new WeChatTemplateMsg("keyword3"));
        sendMap.put("keyword4", new WeChatTemplateMsg("keyword4"));
        sendMap.put("remark", new WeChatTemplateMsg("remark"));

        MiniprogramDto miniprogramDto = new MiniprogramDto();
        miniprogramDto.setAppid(wxMiniPromAppId);
        //跳转到的小程序的界面路径(page.json中的path参数)可带参数,小程序端 onload(options) 接收参数
        miniprogramDto.setPagepath("pages/xxxx/index?storeId=" + 1);

        Map<String, Object> map = getNotifyMapWithMiniProm("oI9SZ6Jt-myBmVhbaGxOJuglUjBY", templateId, sendMap, miniprogramDto);
        ResponseEntity<String> forEntity = restTemplate.postForEntity(NOTIFY_URL + getAccessToken(), map, String.class);
        log.error("通知管理员设备状态完成。请求参数:{},响应参数:{}", map, forEntity);
        return null;
    }

private Map<String, Object> getNotifyMapWithMiniProm(String openId, String templateId, Map<Object, WeChatTemplateMsg> sendMap, MiniprogramDto dto) {
        Map<String, Object> sendBody = new HashMap<>();
        sendBody.put("touser", openId); // openId
        sendBody.put("template_id", templateId);     // 模板Id
        sendBody.put("miniprogram", dto);     // 小程序信息
        sendBody.put("topcolor", "#FF0000");          // 顶色
        sendBody.put("data", sendMap);                   // 模板参数
        return sendBody;
    }

@Data
public class MiniprogramDto {

    private String appid;

    private String pagepath;

}

6.结果
