https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/data-analysis/visit-trend/analysis.getDailyVisitTrend.html 严重bug，begin_date必须和end_date一样才有返回值 数据： req：{"begin_date":"20210911","end_date":"20210912"} res：{"errcode":61501,"errmsg":"date range error rid: 613f14c0-1b1ad127-7d3cab45"} 另一组正常的： req:{"begin_date":"20210912","end_date":"20210912"} res:{"list":[{"ref_date":"20210912","session_cnt":1082,"visit_pv":4573,"visit_uv":495,"visit_uv_new":0,"stay_time_uv":86.0586,"stay_time_session":39.3706,"visit_depth":2.6562}]} 能犯这种低级错误，我也是服了
