json - Accessing a request's body using classic ASP?

Question

How do I access what has been posted by a client to my classic ASP server? I know that there is the Request.Forms variable, but the client's request was not made using a Form. The client request's body is just a string made using a standard POST statement. Thanks

You need to read request bytes if content type of request sent by client is not form data. In this case, request is not a form-data that is accessible through name-value pairs so you cannot use Request.Form collection. I suggest investigate the BinaryRead method.

Reading posted data and convert into string :

If Request.TotalBytes > 0 Then
    Dim lngBytesCount
        lngBytesCount = Request.TotalBytes
    Response.Write BytesToStr(Request.BinaryRead(lngBytesCount))
End If

Function BytesToStr(bytes)
    Dim Stream
    Set Stream = Server.CreateObject("Adodb.Stream")
        Stream.Type = 1 'adTypeBinary
        Stream.Open
        Stream.Write bytes
        Stream.Position = 0
        Stream.Type = 2 'adTypeText
        Stream.Charset = "iso-8859-1"
        BytesToStr = Stream.ReadText
        Stream.Close
    Set Stream = Nothing
End Function

Hope it helps.

Update #1:

With using JScript

if(Request.TotalBytes > 0){
    var lngBytesCount = Request.TotalBytes
    Response.Write(BytesToStr(Request.BinaryRead(lngBytesCount)))
}

function BytesToStr(bytes){
    var stream = Server.CreateObject("Adodb.Stream")
        stream.type = 1
        stream.open
        stream.write(bytes)
        stream.position = 0
        stream.type = 2
        stream.charset = "iso-8859-1"
    var sOut = stream.readtext()
        stream.close
    return sOut
}
