Consuming Web Service using classis ASP

am 04.06.2007 21:42:42 von Mo hariri

Hi,

I can not find a decent example showing how to consume a asp.net 2.0
web service using classic ASP. Does any body have an example I could
use?

Thanks

It's not something a lot of us do. All I can suggest is a google search.
I seem to remember 4GuysFromRolla had a good article about it.

Thank you all for your great posts. I have created a simple helloworld
service which I am trying to call from ASP. I am using the following
code which is posted in one of the sites I found.:

html>

Calling a webservice from classic ASP

<%
If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
Dim xmlhttp
Dim DataToSend
DataToSend="param1="&Request.Form("text1")
Dim postUrl
postUrl = " http://xxxlon.xxxmo.com/AWS.asmx/TestService HTTP/1.1"
Set xmlhttp = server.Createobject("MSXML2.XMLHTTP")
xmlhttp.Open "POST",postUrl,false
xmlhttp.setRequestHeader "Content-Type", _
"application/x-www-form- urlencoded"
xmlhttp.send DataToSend
Response.Write(xmlhttp.responseText)
End If
%>

But when I access the page I am getting the following error:

Request format is unrecognized for URL unexpectedly ending in '/
TestService'.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Request format is
unrecognized for URL unexpectedly ending in '/TestService'.

If I remove the /TestService from the service url I get the following
error after I submit the form:

soap:ReceiverSystem.Web.Services.Protocols.SoapException: Server was
unable to process request. ---> System.Xml.XmlException: Data at the
root level is invalid. Line 1, position 1.

What am I doing wrong?

Thanks

I know this does not address your initial problem, but you have created the
potential for more by using the MSXML2.XMLHTTP object when you ought to use
the server-safe MSXML2.ServerXMLHTTP.

looks like a problem with the posturl

try removing "HTTP/1.1"

Thank you for all your great posts. I am still haven't been able to
get it to work. After I change the object to MSXML2.ServerXMLHTTP I
am getting 500 error on the browser after the button click. I also
tried removeing http/1.1 from the desciprion of the service and I get
the error saying that unexpected ending in /TestService.

Any other recommendations? There must be a working code somewhere. I
do not believe I am the first guy looking for this.

Thanks
