Azure Storage: Set Blob Service Properties

Azure Storage Blob Service REST API: Sample code to set a blob's service properties. VB.NET

Dim success As Boolean = False

' Azure Blob Service Example: Set Blob Service Properties
' See also: https://msdn.microsoft.com/en-us/library/azure/hh452235.aspx

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

Dim rest As New Chilkat.Rest

' Connect to the Azure Storage Blob Service
Dim bTls As Boolean = True
Dim port As Integer = 443
Dim bAutoReconnect As Boolean = True
' In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect)
If (success <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


' Provide Azure Cloud credentials for the REST call.
Dim azAuth As New Chilkat.AuthAzureStorage
azAuth.AccessKey = "AZURE_ACCESS_KEY"
' The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = "chilkat"
azAuth.Scheme = "SharedKey"
azAuth.Service = "Blob"
' This causes the "x-ms-version: 2021-08-06" header to be automatically added.
azAuth.XMsVersion = "2021-08-06"
success = rest.SetAuthAzureStorage(azAuth)

' Note: The application does not need to explicitly set the following
' headers: x-ms-date, Authorization.  These headers
' are automatically set by Chilkat.

' This example will set logging properties.  The XML body of the request
' will look like this:

' <?xml version="1.0" encoding="utf-8"?>
' <StorageServiceProperties>
'     <Logging>
'         <Version>version-number</Version>
'         <Delete>true|false</Delete>
'         <Read>true|false</Read>
'         <Write>true|false</Write>
'         <RetentionPolicy>
'             <Enabled>true|false</Enabled>
'             <Days>number-of-days</Days>
'         </RetentionPolicy>
'     </Logging>

' Build the request:
Dim xml As New Chilkat.Xml
xml.Tag = "StorageServiceProperties"
Dim xLogging As Chilkat.Xml = xml.NewChild("Logging","")
xLogging.NewChild2("Version","1.0")
xLogging.NewChild2("Delete","true")
xLogging.NewChild2("Read","true")
xLogging.NewChild2("Write","true")
Dim xRetension As Chilkat.Xml = xLogging.NewChild("RetentionPolicy","")
xRetension.NewChild2("Enabled","true")
xRetension.NewChild2("Days","7")



' The expected response is a 202 response status code with no response body.
Dim responseStr As String = rest.FullRequestString("PUT","/?restype=service&comp=properties",xml.GetXml())
If (rest.LastMethodSuccess <> True) Then
