求助：如何解决微信公众号API中POST提交后的反馈JOSN数据的解析！谢谢
Dim postdata As String ="{""type"":""news"",""offset"":""0"",""count"":""2""}"
Dim dr As DataRow =DataTables("ACCESS_TOKEN").Find("公众号名称 = \'黔源科技\'")
Dim url = String.Format("https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=" & dr("ACCESSTOKEN") & "")
Using ms As New System.IO.MemoryStream()
Dim bytes = ConvertHelper.EncodingToBytes(postdata, System.Text.Encoding.UTF8)
ms.Write(bytes, 0, bytes.Length)
ms.Seek(0, System.IO.SeekOrigin.Begin)
Dim jsonString = Functions.Execute("HttpPost",url, ms) \'通过POST向接口传输菜单数据,并取得返回结果
\'output.show(jsonString )
End Using
上述代码可以实现当前图文信息的获取了 但是怎么实现将反馈得到的JSON数据解析出来呢？
官方提示：永久图文消息素材列表的响应如下：
{
"total_count": TOTAL_COUNT,
"item_count": ITEM_COUNT,
"item": [{
"media_id": MEDIA_ID,
"content": {
"news_item": [{
"title": TITLE,
"thumb_media_id": THUMB_MEDIA_ID,
"thumb_url": THUMB_URL,
"show_cover_pic": SHOW_COVER_PIC(0 / 1),
"author": AUTHOR,
"digest": DIGEST,
"content": CONTENT,
"url": URL,
"content_source_url": CONTETN_SOURCE_URL
},
//多图文消息会在此处有多篇文章
]
},
"update_time": UPDATE_TIME
},
//可能有多个图文消息item结构
]
}返回的值我需要得到title 、 author 、 url 、update_time这四个值 怎么实现操作呢？

下面的代码是实现GET方式得到的JSON文件解析，经操作是可以实现解析的：但是对应POST的我不熟悉操作，烦请大家多多指导下！谢谢
Dim XMLH As Object
XMLH = CreateObject("Microsoft.XMLHTTP")
Dim drs As List(Of DataRow) = DataTables("ACCESS_TOKEN").Select("AppID应用ID is not null")
For Each dr As DataRow In drs
XMLH.open("GET", "https://api.weixin.qq.com/datacube/getusershare?access_token=" & dr("ACCESSTOKEN") & "", True) \'获得实时信息
XMLH.send(Nothing)
Do While XMLH.readyState <> 4
Application.DoEvents
Loop
\'
\'把数据json数据转化成对象
Dim json As String = XMLH.responseText
Dim ScriptControl As Object, data As Object, JscriptCode As String
JscriptCode = "function toObject(json) {eval(""var o=""+json);return o;}"
ScriptControl = CreateObject("MSScriptControl.ScriptControl")
With ScriptControl
.Language = "Javascript"
.Timeout = -1
.AddCode(JscriptCode)
data = .Run("toObject", json)
End With
MessageBox.Show(json)
dr("voice_count") = data.voice_count
MessageBox.Show(dr("video_count"))
Next
看看上面的代码怎么变通下实现呢？ 谢谢啦

有点蓝老师：你楼上的代码我测试了一下，和我下面仿写的代码运行时候出现的错误是一致的，
错误如图：
代码如下：
Dim dr As DataRow = DataTables("ACCESS_TOKEN").Find("公众号名称 = \'黔源科技\'")
Dim XMLH As Object
XMLH = CreateObject("Microsoft.XMLHTTP")
XMLH.open("post", "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=" & dr("ACCESSTOKEN") & "", True) \'获得实时信息
XMLH.send("{""type"":""news"",""offset"":""0"",""count"":""2""}")
Do While XMLH.readyState <> 4
Application.DoEvents
Loop
Dim json As String = XMLH.responseText
Dim ScriptControl As Object, data As Object, JscriptCode As String
JscriptCode = "function toObject(json) {eval(""var o=""+json);return o;}"
ScriptControl = CreateObject("MSScriptControl.ScriptControl")
With ScriptControl
.Language = "Javascript"
.Timeout = -1
.AddCode(JscriptCode)
data = .Run("toObject", json)
End With
\'MessageBox.Show(json)
dr("title") = data.title
MessageBox.Show(dr("title"))
