获取微信公众号图文消息写法记录

微信公众平台官网:https://mp.weixin.qq.com

数据统计模块儿，图文分析数据接口（以getarticletotal接口为例）

https://api.weixin.qq.com/datacube/getarticletotal?access_token=ACCESS_TOKEN

接口介绍：

该接口只有三个参数，access_token 是请求接口的凭证，是必须要的，begin_date和end_date，最大跨度时间为1天，也就是两个参数必须是同一天，end_date允许设置的最大值为昨日，但最多统计发表日后7天数据。
了解了规则，接下来撸代码：
实例化微信工具类（自写）

WeixinUtil wu = new WeixinUtil(gi.getOriginalId() + "", gi.getAppId(), gi.getSecret(), "", "");

然后调用接口

Map<String, Object> map = wu.getArticleTotal(day, day);

getArticleTotal接口内

// 图文素材接口
    public Map<String, Object> getArticleTotal(String begin_date, String end_date) throws Exception {
String url = "https://api.weixin.qq.com/datacube/getarticletotal?access_token=" + getAccessToken();
        String json = HttpRequestHelper.paramsPostJson(url,"{\"begin_date\": \"" + begin_date + "\",\"end_date\": \"" + end_date + "\"}");
        validateAccessToken(json);
        Map<String, Object> map1 = JacksonHelper.fromJSON(json, HashMap.class);
        return map1;
    }

接下来，是上一段代码中getAccessToken方法

public String getAccessToken() throws Exception {
        //先看redis里是否有，为空就接口获取
        if (RedisUtil.getStringValue(RANDOM_REDIS_ACCESS_TOKEN + appid) == null
                || "".equals(RedisUtil.getStringValue(RANDOM_REDIS_ACCESS_TOKEN + appid))) {
            String sendurl = (new StringBuilder("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid="))
                    .append(appid).append("&secret=").append(secret).toString();
            HttpRequester req = new HttpRequester();
            HttpResponser res = req.sendGet(sendurl);
            String myjson = res.getContent();
            //json转map
            HashMap jo = JacksonHelper.fromJSON(myjson, HashMap.class);
            String accessToken = (String) jo.get("access_token");
            if (accessToken != null && !"".equals(accessToken)) {
                RedisUtil.setExpireString(RANDOM_REDIS_ACCESS_TOKEN + appid, EXPIRES_IN, accessToken);//存redis
            }
            //如果accessToken为空，
            if (accessToken == null || "".equals(accessToken)) {
                return myjson;
            }
            return accessToken;
        } else {
            return RedisUtil.getStringValue(RANDOM_REDIS_ACCESS_TOKEN + appid);
            //取AccessToken
        }
    }

把返回的数据拿出来

List<Map<String, Object>> list = (ArrayList<Map<String, Object>>) map.get("list");

遍历这个list，加入实体类

for (Map<String, Object> aSum : list) {}

GzhDayArticle gda = new GzhDayArticle(gi.getGzhId(), title,
                                        aSum.get("msgid").toString(), article.get("stat_date").toString(), day,
                                        Integer.parseInt(article.get("target_user") + ""),
                                        Integer.parseInt(article.get("share_user") + ""),
                                        Integer.parseInt(article.get("share_count") + ""),
                                        Integer.parseInt(article.get("add_to_fav_user") + ""),
                                        Integer.parseInt(article.get("add_to_fav_count") + ""),
                                        Integer.parseInt(article.get("int_page_from_session_read_user") + ""),
                                        Integer.parseInt(article.get("int_page_from_session_read_count") + ""),
                                        Integer.parseInt(article.get("int_page_from_feed_read_user") + ""),
                                        Integer.parseInt(article.get("int_page_from_feed_read_count") + ""),
                                        Integer.parseInt(article.get("int_page_from_friends_read_user") + ""),
                                        Integer.parseInt(article.get("int_page_from_friends_read_count") + ""),
                                        departmentNo, userId, Integer.parseInt(article.get("int_page_read_user") + ""),
                                        Integer.parseInt(article.get("int_page_read_count") + ""));
                                gzhService.saveGzhDayArticle(gda);
