Backblaze S3 List Buckets

See more Backblaze S3 Examples

Demonstrates how to list Backblaze buckets.

The Chilkat S3 functions in the HTTP class are compatible with the Backblaze service. However, because of some specific issues, Chilkat v9.5.0.89 or later is needed.

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

' keyID = Access Key ID or Access Key
http.AwsAccessKey = "access-key"

' applicationKey = Secret Access Key or Secret Key
http.AwsSecretKey = "secret-key"

' Region is the 2nd part of your S3 Endpoint
http.AwsEndpoint = "s3.us-west-002.backblazeb2.com"

Dim bucketsXml As String = http.S3_ListBuckets()

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