Get/post to RESTful web service

You'll need to add a reference to the MSXML library:

Dim sUrl As String
Dim response As String
Dim xmlhttp

Set sUrl = "http://my.domain.com/service/operation/param"

Set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP")
xmlhttp.open "POST", sURL, False
xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
xmlhttp.send()

Dim response As String = xmlhttp.responseText

Set xmlhttp = Nothing

I needed this for GET requests in an old legacy application recently, and since the accepted answer doesn't compile I thought I'd post some working code. I'm sure it will help some poor sole using VB6 in the future ;) Here's a nice clean function.

Public Function WebRequest(url As String) As String
    Dim http As MSXML2.XMLHTTP
    Set http = CreateObject("MSXML2.ServerXMLHTTP")

    http.Open "GET", url, False
    http.Send

    WebRequest = http.responseText
    Set http = Nothing
End Function

And here's example usage:

Dim result As String
Dim url As String

url = "http://my.domain.com/service/operation/param"
result = WebRequest(url)

Happy VB6ing! :)
