OSS List Buckets (Alibaba Cloud)

See more Alibaba Cloud OSS Examples

Demonstrates how to list AliCloud OSS buckets.

The Chilkat S3 functions in the HTTP class are compatible with Alibaba Cloud's OSS service.

VB.NET

Dim success As Boolean = False

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

Dim http As New Chilkat.Http

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

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

' See Alibaba Object Storage Service Regions and Endpoints
http.AwsEndpoint = "oss-us-west-1.aliyuncs.com"

Dim bucketsXml As String = http.S3_ListBuckets()

If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Dim xml As New Chilkat.Xml
xml.LoadXml(bucketsXml)
Debug.WriteLine(xml.GetXml())
