testing curl webservices

Question

I've just gotten the go-ahead to start automating our curl webservice calls. I'm hoping there's some way to do this without starting curl up as a separate application and parsing the command lines.

Has anybody worked with curl requests & responses in TestComplete?

You can create an JScript HTTP client in a similar way to creating an AJAX client in (an old) IE browser, e.g.:&nbsp; &nbsp; function GET (URL) {&nbsp; &nbsp; &nbsp; &nbsp; var XmlHttpRequest = Sys["OleObject"]("MSXML2.XMLHTTP.3.0");&nbsp; &nbsp; &nbsp; &nbsp; XmlHttpRequest.open("GET", URL, false);&nbsp; &nbsp; &nbsp; &nbsp; XmlHttpRequest.setRequestHeader("Content-Type", "application/json"); &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; XmlHttpRequest.send();&nbsp; &nbsp; &nbsp; &nbsp; try {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return XmlHttpRequest.responseText;&nbsp; &nbsp; &nbsp; &nbsp; } catch (e) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return "Error";&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }This example makes a synchronous call to a URL, expecting a JSON response and returning it as a string. You can adapt this basic idea for different content types, POSTs, etc. I don't think it's possible to write this as asynchronous since TestComplete doesn't have the browser's event loop.

For others purposes, I've added what I ended up with.1) I'm using the ActiveXObject rather than the Sys("OleObject) as Nick suggested.Does anybody have a comment on when to use ActiveX...&nbsp; versus Ole.... ? 2) I modified the GET code to support PUT or POST with form data, since some of the webservices use that.3) The curl specific parameters are NOT needed when constructing the XmlHttpRequest.&nbsp; I imagine this is a "No DUH !" for everybody with any familiarity at all with this stuff, but came as an epiphany to me. =====================================================function http_request (URL, method, formData) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var XmlHttpRequest = new ActiveXObject("MSXML2.XMLHTTP.3.0");&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if ( ( method == undefined) || (method == "") ) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; method = "GET"; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // XmlHttpRequest.open( Method, URL, Asynchronous, UserName, Password)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // method e.g. GET, POST, HEAD, PUT, DELETE, OPTIONS...&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Asynchronous = true, do not wait on a server response,&nbsp; false, pause current execution utnil the request is complete &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XmlHttpRequest.open(method, URL, false);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Name, Value &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XmlHttpRequest.setRequestHeader("Content-Type", "application/json"); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XmlHttpRequest.setRequestHeader("access_token",&nbsp; access_token_variable_or_constant); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; XmlHttpRequest.send(formData);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; try {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return XmlHttpRequest.responseText;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; } &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; catch (e) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return "Error" + e ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }}=================Thanks Again Nick!&nbsp;&nbsp; Regards,&nbsp; Curt Hicks
