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

    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.

    rest := chilkat.NewRest()

    // Connect to the Azure Storage Blob Service
    bTls := true
    port := 443
    bAutoReconnect := true
    // In this example, the storage account name is "chilkat".
    success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect)
    if success != true {
        fmt.Println(rest.LastErrorText())
        rest.DisposeRest()
        return
    }

    // Provide Azure Cloud credentials for the REST call.
    azAuth := chilkat.NewAuthAzureStorage()
    azAuth.SetAccessKey("AZURE_ACCESS_KEY")
    // The account name used here should match the 1st part of the domain passed in the call to Connect (above).
    azAuth.SetAccount("chilkat")
    azAuth.SetScheme("SharedKey")
    azAuth.SetService("Blob")
    // This causes the "x-ms-version: 2021-08-06" header to be automatically added.
    azAuth.SetXMsVersion("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>

    //         <Read>true|false</Read>
    //         <Write>true|false</Write>
    //         <RetentionPolicy>
    //             <Enabled>true|false</Enabled>
    //             <Days>number-of-days</Days>
    //         </RetentionPolicy>
    //     </Logging>

    // Build the request:
