* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loRest = CreateObject('Chilkat.Rest')

* Connect to the Amazon AWS REST server.
* such as https://sqs.us-west-2.amazonaws.com/
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("sqs.us-west-2.amazonaws.com",lnPort,lnBTls,lnBAutoReconnect)

* Provide AWS credentials for the REST call.
loAuthAws = CreateObject('Chilkat.AuthAws')
loAuthAws.AccessKey = "AWS_ACCESS_KEY"
loAuthAws.SecretKey = "AWS_SECRET_KEY"
* the region should match our URL above..
loAuthAws.Region = "us-west-2"
loAuthAws.ServiceName = "sqs"

loRest.SetAuthAws(loAuthAws)

loRest.AddQueryParam("Action","ReceiveMessage")
loRest.AddQueryParam("MaxNumberOfMessages","5")
loRest.AddQueryParam("VisibilityTimeout","15")
loRest.AddQueryParam("AttributeName","All")
loRest.AddQueryParam("MessageAttributeName","All")

* Use the actual path part of your SQS queue URL here:
lcResponseXml = loRest.FullRequestNoBody("GET","/123456789123/chilkatTest")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAuthAws
    CANCEL
ENDIF

* A successful response will have a status code equal to 200.
IF (loRest.ResponseStatusCode <> 200) THEN
    ? "response status code = " + STR(loRest.ResponseStatusCode)
    ? "response status text = " + loRest.ResponseStatusText
    ? "response header: " + loRest.ResponseHeader
    ? "response body: " + lcResponseXml
    RELEASE loRest
    RELEASE loAuthAws
    CANCEL
ENDIF

* Examine the successful XML response.
loXml = CreateObject('Chilkat.Xml')
loXml.LoadXml(lcResponseXml)
? loXml.GetXml()
? "----"

* A successful response looks like this:
