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

Dim http As ChilkatHttp
http.Initialize("http")

'  Insert your AccessKey ID here:
http.AwsAccessKey = "access-key"

'  Insert your AccessKey Secret here:
http.AwsSecretKey = "secret-key"

'  To download from a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
'  See Alibaba Object Storage Service Regions and Endpoints
http.AwsEndpoint = "oss-us-east-1.aliyuncs.com"

Dim bucketName As String = "chilkat"
Dim objectName As String = "orchard.json"

'  This is the byte representation of the text file downloaded from Aliyun.
'  It must be specified to allow Chilkat to correctly interpret the bytes as characters.
Dim charset As String = "utf-8"

Dim fileContents As String = http.S3_DownloadString(bucketName, objectName, charset)

If http.LastMethodSuccess <> True Then
    Log(http.LastErrorText)
Else
    Log(fileContents)
    Log("Success.")
End If
