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

Dim success As Boolean
success = 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
bTls = True
Dim port As Int32
port = 443
Dim bAutoReconnect As Boolean
bAutoReconnect = True
// In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect)

    Return
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
xLogging = xml.NewChild("Logging","")
xLogging.NewChild2 "Version","1.0"
xLogging.NewChild2 "Delete","true"
