am using Request.ServerVariables to get webhook response from GoCardless in classic asp which is calling a page on my server http:/www.example.com/webhook.asp
My code in webhook.asp:
For Each var in Request.ServerVariables
WriteLog var & " = " & Request.ServerVariables(var) , "gocardless"
Next
the output is ok, i can read
Content-Length: 353
Content-Type: application/json
Accept: */*
Accept-Encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3

Answer 1

well after more than 48 hours of google search this fixed my problem
Dim lngBytesCount, bstring
If Request.TotalBytes > 0 Then
lngBytesCount = Request.TotalBytes
bstring= BytesToStr(Request.BinaryRead(lngBytesCount))
response.Clear
WriteLog bstring , "gocardless"
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 = "UTF-8"
BytesToStr = Stream.ReadText
try = BytesToStr
Stream.Close
Set Stream = Nothing
End Function

ok guys thanks all for your hel but this is the complete solution that helped solving my problem and it works great

dim filename : filename = Request.ServerVariables("HTTP_Webhook-Signature")
'response.write "filename = " & filename

Dim lngBytesCount, bstring
If Request.TotalBytes > 0 Then
lngBytesCount = Request.TotalBytes
response.ContentType = "application/json;charset=UTF-8"
bstring= BytesToStr(Request.BinaryRead(lngBytesCount))
'response.Clear
end if
'response.write bstring
'---------------------------------------------------------------------------------------------------
WriteLog bstring , filename
'---------------------------------------------------------------------------------------------------
Set oJSON = New aspJSON
oJSON.loadJSON bstring
For Each record In oJSON.data("events")
Set this = oJSON.data("events").item(record)
Response.Write "<p>" & this.item("id") '& " | " & this.item("charge_date") & " | " & this.item("amount") & " | " & this.item("description") & " | " & this.item("status") & " | " & this.item("links")("mandate") & " | " & this.item("links")("subscription") & "<p>"
