Posting data from ASP to WebService

How can I send string from classic ASP to .Net web service?


J_P October 31st, 2010 12:54 PM

it doesn't matter what type of code the webservice uses.

ASP can send the string as a querystring via the url.

function GetIt(strUrl)
Dim xmlhttp
Set xmlhttp=Server.CreateObject("MSXML2.ServerXMLHTTP"  )
xmlhttp.open "GET",strUrl,false
GetIt = xmlhttp.responseText
Set xmlhttp=nothing
end function

Not true, at all.

If the Web Service is using SOAP, which 99.5% of all ASP.NET Web Services do (because that's what the ASP.NET framework automatically creates for you when you ask for a Web Service) then you
(a) can *NOT* use "GET"; you MUST use "POST"
(b) MUST send a CORRECTLY FORMATTED request, using XML notation, with the XML parameters, etc., that the SOAP service is expecting.

It's not easy. But it can be done.

Google for "SOAP via classic ASP" or something to that effect.

Oh, yes...and the response you will receive will *ALSO* be in SOAP format. So you will need to learn to use the XML DOM to read it.

not that big of a deal - use post if you wish...

sending xml is just as easy as sending a string and so is receiving it...

I've done it with simple code as shown above.

LOL! Well, sure, if you have used XML quite a bit. But I'm assuming that anyone newbie enough to need to ask the question will be utterly lost when it comes to creating a proper SOAP request. Possibly even lost when it comes to handling the XML response.

As for "use post if you wish": Depending on how big the request needs to be, you may have no choice. And certainly won't have a choice if the ASP.NET code is *ONLY* looking for posted data.

I rarely use XML.

This is just not that complicated. Stop trying to make it sound like rocket science. It's as simple as it looks in the code example above.

If the OP has problems with xml they will post another question - likely to the XML forums...

And clearly you've never used a stanadard ASP.NET Web Service. Or a SOAP Web Service, at all.


Granted, that shows using an HTTP Post, but that's only possible with really really simple web services. The two SOAP versions are much more typical.

Well, we shall see if and when the OP comes back.

You make a lot of assumptions. A bad habit.

I will withdraw the comment. But for the rest I'll still wait to see what the OP intended. It would have been helpful if he'd shown the web service he wanted to query.
