发送微信小程序卡片到公众号

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

@Componentpublic 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./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;}
