// 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.

loRest = createobject("CkRest")

// Connect to the Azure Storage Blob Service
llBTls = .T.
lnPort = 443
llBAutoReconnect = .T.
// In this example, the storage account name is "chilkat".
llSuccess = loRest.Connect("chilkat.blob.core.windows.net",lnPort,llBTls,llBAutoReconnect)
if (llSuccess <> .T.) then
    ? loRest.LastErrorText
    release loRest
    return
endif

// Provide Azure Cloud credentials for the REST call.
loAzAuth = createobject("CkAuthAzureStorage")
loAzAuth.AccessKey = "AZURE_ACCESS_KEY"
// The account name used here should match the 1st part of the domain passed in the call to Connect (above).
loAzAuth.Account = "chilkat"
loAzAuth.Scheme = "SharedKey"
loAzAuth.Service = "Blob"
// This causes the "x-ms-version: 2020-08-04" header to be automatically added.
loAzAuth.XMsVersion = "2020-08-04"
llSuccess = loRest.SetAuthAzureStorage(loAzAuth)

// 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:
loXml = createobject("CkXml")
loXml.Tag = "StorageServiceProperties"
loXLogging = loXml.NewChild("Logging","")
loXLogging.NewChild2("Version","1.0")
loXLogging.NewChild2("Delete","true")
