微信服务号下可以主动给用户推送小程序卡片,但是得用户授权接受消息才可以,小程序卡片点击即可跳转到小程序中对应的页面

前提是服务号要与小程序绑定,且是同一主体.

1.发送卡片工具类

@Component
    public class SendAppletsCard {
    
        private static final Logger logger = Logger.getLogger(SendAppletsCard.class.getName());
    
        public Integer sendCard(String appletsAppid,String GZHappid,String GZHsecret,String title,String touser,String pagepath,String mediaid){
            try {
                Map<String, Object> params = new HashMap<>();
                params.put("touser", touser);
                params.put("msgtype", "miniprogrampage");
                Map<String, Object> miniprogrampageMap = new HashMap<>();
                miniprogrampageMap.put("title", title);
                miniprogrampageMap.put("appid", appletsAppid);
                miniprogrampageMap.put("thumb_media_id", mediaid);
                miniprogrampageMap.put("pagepath", pagepath);
                params.put("miniprogrampage", miniprogrampageMap);
                String token = WechatUtil.getToken(GZHappid, GZHsecret).getAccessToken();
                logger.info("token:--------"+token);
                String PUSH_APPLET_URL = AppletsConstant.PUSH_APPLET_URL + token;
                JSONObject result = WX_HttpsUtil.httpsRequest(PUSH_APPLET_URL, "POST", JSON.toJSONString(params));
                logger.info(JSON.toJSONString(params)+"jsonString---------------");
                JSONObject resultJson = new JSONObject(result);
                logger.info("发送小程序卡片结果：" + resultJson.toString());
                if(resultJson.getInteger("errcode")==40003){
                    //获取新的token并保存到redis中   重新推消息
                    token = WechatUtil.getToken2(GZHappid, GZHsecret).getAccessToken();
                    logger.info("新token:--------"+token);
    
                    Map<String, Object> params2 = new HashMap<>();
                    params2.put("touser", touser);
                    params2.put("msgtype", "miniprogrampage");
                    Map<String, Object> miniprogrampageMap2 = new HashMap<>();
                    miniprogrampageMap2.put("title", title);
                    miniprogrampageMap2.put("appid", appletsAppid);
                    miniprogrampageMap2.put("thumb_media_id", mediaid);
                    miniprogrampageMap2.put("pagepath", pagepath);
                    params.put("miniprogrampage", miniprogrampageMap2);
                    String PUSH_APPLET_URL2 = AppletsConstant.PUSH_APPLET_URL + token;
                    JSONObject result2 = WX_HttpsUtil.httpsRequest(PUSH_APPLET_URL2, "POST", JSON.toJSONString(params2));
                    JSONObject resultJson2 = new JSONObject(result2);
                    logger.info("发送小程序卡片结果2：" + resultJson2.toString());
                    return resultJson2.getInteger("errcode");
                }
                return resultJson.getInteger("errcode");
            } catch (Exception e) {
                e.printStackTrace();
                return -1;
            }
        }
    }

2.获取素材列表工具类

public class TestMediaList {
        public String getMediaId(String appid,String secret){
            String token = WechatUtil.getToken(appid, secret).getAccessToken();
            String url = "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token="+token;
            WXMediaListUtil media = new WXMediaListUtil();
            media.setOffset(0);
            media.setCount(10);
            media.setType("image");
            JSONObject json = (JSONObject) JSONObject.toJSON(media);
            JSONObject result = WX_HttpsUtil.httpsRequest(url,"POST",json.toJSONString());
            JSONArray arr = result.getJSONArray("item");
            JSONObject jsonObj = arr.getJSONObject(0);
            String media_id = jsonObj.get("media_id").toString();
            return media_id;
        }
    }

3.获取token工具类

public static Token getToken(String appid, String appsecret) {
            Token token = null;
            String redis_token=redisUtil.getData(wechat_token_redis_name+":"+appid);
            if (null==redis_token){
                String requestUrl = token_url.replace("APPID", appid).replace("APPSECRET", appsecret);
                // 发起GET请求获取凭证
                JSONObject jsonObject = httpsRequest(requestUrl, "GET", null);
                if (null != jsonObject) {
                    try {
                        token = new Token();
                        token.setAccessToken(jsonObject.getString("access_token"));
                        token.setExpiresIn(jsonObject.getInt("expires_in"));
                        //将微信token保存到redis中，失效时间与token失效时间相同
                        redisUtil.setData(wechat_token_redis_name+":"+appid, token.getAccessToken(), token.getExpiresIn());
                    } catch (JSONException e) {
                        token = null;
                        // 获取token失败
                        log.error("获取token失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg"));
                    }
                }
            }else{
                token=new Token();
                token.setAccessToken(redis_token);
                token.setExpiresIn(7200);
            }
            return token;
        }
