在搜索同类问题未解决后,我根据专员回复,将我的问题叙述清楚

鉴于昨天我发布帖子以后,https://developers.weixin.qq.com/community/develop/doc/000ca21411c8a888017be69b251400

好像发错了模块,也已经过了18小时,失去了排查的最佳时机.故此重新发帖

AppID : wx3bd5bca46dc6d8ac

第一步:

获取(09:12:41)token 以后 使用media/upload上传临时素材返回mediaId(09:12:43收到)

{
  "item": [],
  "media_id": "hebQsBY6OusmLZVVd832FxlsmRFf5lvIukpUJ-_e9CoUZiIo7NIbVFDiCZAkoGmL",
  "created_at": 1608685964,
  "type": "video"
}

第二步:

09:12:43发送/media/uploadvideo接口,提交至图文视频指定接口 ,获取media_id ,url和内容如下

https://api.weixin.qq.com/cgi-bin/media/uploadvideo?access_token=40_u1x1znttJgBq-WEtw_poXXzPq67D30-hWp_btqW-lcDlH6fD7d9v-ghz1HjxPWZPqiNDujkT1haDcn2S-Ejmg7ipMncfCf3BgMDYvYIJdQSuh5QLG-uqrX48G6WMPzl4MNHIAJsHKBN6vL9yVCVbAFANUN   
{"media_id":"hebQsBY6OusmLZVVd832FxlsmRFf5lvIukpUJ-_e9CoUZiIo7NIbVFDiCZAkoGmL","description":"微信公众号API视频开发","title":"视频图文的标题"}

收到09:12:44

{"type":"video","media_id":"AMnyPjvxhEm6dBFMi_g_ep9UI-M8js07KsV9Hzwz0ZR80eBdO3Bt81FpU-q9l1WP","created_at":1608685964,"item":[]}

第三步

09:12:44调用/mass/preview预览接口,url+内容如下

https://api.weixin.qq.com/cgi-bin/message/mass/preview?access_token=40_u1x1znttJgBq-WEtw_poXXzPq67D30-hWp_btqW-lcDlH6fD7d9v-ghz1HjxPWZPqiNDujkT1haDcn2S-Ejmg7ipMncfCf3BgMDYvYIJdQSuh5QLG-uqrX48G6WMPzl4MNHIAJsHKBN6vL9yVCVbAFANUN   
{"touser":"o5hmdwN-vmOodaAKOh8nSIxsFuf4","msgtype":"mpvideo","mpvideo":{"media_id":"AMnyPjvxhEm6dBFMi_g_ep9UI-M8js07KsV9Hzwz0ZR80eBdO3Bt81FpU-q9l1WP"}}

根据预览接口的文档返回应该有个``msg_id``参数,这里没有,09:12:44收到如下,这个是因为

{"errcode":0,"errmsg":"preview success"}

此时,指定微信已经收到来自公众号的推送

打开链接显示:

谢谢解决.
