In this video, I show a quick example on how to use QuickTest Pro 11 and WinHttp to test a REST service. The QTP web-addin is not needed for this example.

Below is the code used for this example:

Set myRestBody = XMLUtil.CreateXMLFromFile("C:\body.xml") 
restRequest = myRestBody.ToString
url ="http://localhost:24240/HPFlights_REST/FlightOrders/"
contentType ="text/XML"
'1) Create reference to the WinHTTP request com object
 Set oWinHttp = CreateObject("WinHttp.WinHttpRequest.5.1") 
 '2) Open a HTTP connection to a HTTP resource 
 oWinHttp.Open "POST", url, False
 '3) Add a HTTP request headers for endpoint and conent type
 oWinHttp.setRequestHeader "Content-Type", contentType  oWinHttp.setRequestHeader "SOAPAction", url
'4) Send a HTTP request to the HTTP server with the header and body info
oWinHttp.Send restRequest
'5) Get response
 response = oWinHttp.ResponseText
'6) Close object reference 
Set oWinHttp = Nothing
'7) print the response
print response
  1. hi joe,
    i have a xml, public key and a private key. i would like to know if i can digitially sign this xml and then send it to a webservice using qtp. not the service test.
    thank you

  2. shaan » Hi Shaan – I’m not sure how to do this. Have you taken a look at the AddAttachment or AddHeader Methods of the WebService object? Good Luck ~Joe

  3. Hi Joe
    thanks for you code. I have to authenticate before
    ‘4) Send a HTTP request to the HTTP server with the header and body info
    oWinHttp.Send restRequest
    How do i do that?

    Thanks
    Sarma

  4. Sarma » Hi Sarma – you might want to try using the SetCredentials method. The SetCredentials method sets credentials to be used with an HTTP server, whether it is a proxy server or an originating server.

    Const HTTPREQUEST_SETCREDENTIALS_FOR_SERVER = 0

    WinHttpReq.SetCredentials “yourusername”, ourHTTPREQUEST_SETCREDENTIALS_FOR_SERVER
