我通过curl命令：curl -F media=@C:\ALiYun测试网络服务端\Debug\20200721\0320000798D863B887BA_144421.mp3 "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=35_MJEuqw4cjTBdW_ka1pfH3vJ8vowcxF2tJFDN7KkHzvP-aBts4nmA2VQl7poddXsEaHzVLHsqB2boTCh6F7NZR2lRvMBsCl8c-HMSP7G7G--KYhl-dI6BIMDGlCh-Dsw537ROub92YzNMPN3-KWNcAAABNE&type=voice"把语音文件上传到了微信公众号的永久素材库中， 微信公众号返回一个Media_id：{"media_id":"_vwOaATvkPgGff2uTvSqanLHdoBTvYf0lfZR1EoP4oM","item":[]} 但是我通过这个Media_id查询： https://api.weixin.qq.com/cgi-bin/material/get_material?access_token=35_MJEuqw4cjTBdW_ka1pfH3vJ8vowcxF2tJFDN7KkHzvP-aBts4nmA2VQl7poddXsEaHzVLHsqB2boTCh6F7NZR2lRvMBsCl8c-HMSP7G7G--KYhl-dI6BIMDGlCh-Dsw537ROub92YzNMPN3-KWNcAAABNE {    "media_id" : "_vwOaATvkPgGff2uTvSqanLHdoBTvYf0lfZR1EoP4oM" } 返回的查询结果却是：{"errcode":40007,"errmsg":"invalid media_id hint: [ejn8Ya0867d139]"}

上传永久素材的接口返回数据为：{"media_id":"_vwOaATvkPgGff2uTvSqavqqHQGPHlf5I5WXZKrc1Lk","item":[]}； 这是上传的语音文件与media_id的对应关系表存储的数据[图片]
