你参考一下这个接口：https://developers.weixin.qq.com/doc/offiaccount/Message_Management/Batch_Sends_and_Originality_Checks.html

新增草稿箱，请求数据：{
    "articles":[
        {
            "title":"今日新上2辆车，点击查看详情！",
            "author":"公正志诚二手车",
            "digest":"",
            "content":"<mp-miniprogram data-miniprogram-appid=\"wx576be1c52bbc1595\" data-miniprogram-path=\"pages/index/index\" data-miniprogram-title=\"2017款 帝豪 三厢百万款 1.5L 手动向上互联版 5.18万元\" data-miniprogram-imageurl=\"http://mmbiz.qpic.cn/mmbiz_jpg/vgQEu87s3FByEVHy3ERjTuR9BUhxXoR7SMjjMh1AbjUqFuRyCbP1VcWaDiaylH9n9p7Sjz0IGu65fwLvgTibZk4A/0?wx_fmt=jpeg\"></mp-miniprogram>",
            "content_source_url":"",
            "thumb_media_id":"9dAzb7iu-ATwbh_1Bd-Amh4W65FY_Dmtt4UCLB8-GK_fxcHyJwhS087mT08A5Wwj",
            "need_open_comment":0,
            "only_fans_can_comment":0
        }
    ]
} 结果返回：{"errcode":45166,"errmsg":"invalid content hint: [AAdW6a04730043] rid: 6246d219-51d1d485-30557443"} ，就是添加了小程序卡片，就报错，其他都可以发布，不知道为什么？

你先用这个接口上传小程序，然后将返回的ID，再次放入创建草稿接口试试https://developers.weixin.qq.com/doc/offiaccount/Message_Management/Batch_Sends_and_Originality_Checks.html
