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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* Insert your access key here:
loHttp.AwsAccessKey = "access-key"

* Insert your secret key here:
loHttp.AwsSecretKey = "secret-key"

* Use the endpoint matching the bucket's region.
loHttp.AwsEndpoint = "s3.us-west-1.wasabisys.com"

lcBucketName = "chilkattest"

lcStrXml = loHttp.S3_ListBucketObjects(lcBucketName)
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    CANCEL
ENDIF

? "Response status code = " + STR(loHttp.LastStatus)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
loXml = CreateObject('Chilkat.Xml')
lnSuccess = loXml.LoadXml(lcStrXml)
IF (lnSuccess <> 1) THEN
    ? loXml.LastErrorText
    RELEASE loHttp
    RELEASE loXml
    CANCEL
ENDIF

* If the response status code was not 200, then the XML response is not a 
* listing of objects, but instead contains error information.
IF (loHttp.LastStatus <> 200) THEN
    ? loXml.GetXml()
    ? "Failed."
    RELEASE loHttp
    RELEASE loXml
    CANCEL
ENDIF

* A sample response is shown below.
? loXml.GetXml()
? "----"
