Lots of different ways to query a web service:
Here's example of URL encoded form post
The script below returns the equivalent of submitting a FORM as follows:
<FORM ACTION=” http://localhost/test.asp” METHOD=”POST”>
<INPUT NAME=”field1” VALUE=”Kirby” />
<BUTTON TYPE=”submit”></BUTTON>
</FORM>
The trick is that the Content-Type needs to be sent as a request header as follows. Each space needs to be encoded as a + character in the send() argument. Encode non-alphanumeric characters in the method using %XX encoding (for instance, the backslash is encoded as %5c).
Set objHTTP = CreateObject("Microsoft.XMLHTTP")
objHTTP.open "POST", "http://localhost/test.asp", False
objHTTP.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
objHTTP.send "field1=kirby"
MsgBox objHTTP.responseText
Set objHTTP = Nothing
