请教高手，用VBA可以实现微信上传临时素材吗？参数media怎么设置呢？

[qq_39304425]

media 是 form-data中媒体文件标识，有filename、filelength、content-type等信息，
可具体怎么设置呢？


URL = "https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=" & AkToken & "type=image"
http.Open "POST", URL, False
'http.Send " " access_token type media
WX_access_token = AkToken
WX_MEDIA = "D:\wx\aaa.jpg"
WX_uploadimge = "{""access_token"":""" & WX_access_token & """,""media"":""" & WX_MEDIA & """,""type"":""image""}"
http.Send (WX_uploadimge)

跑完 http.Status = 200，但取不到 media_id
明显 media"":""" & WX_MEDIA 不行，可是到底怎么写呢？在线急等，谢谢！
