*  Azure Blob Service Example: Get Blob Service Properties

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

loRest = CreateObject('Chilkat.Rest')

*  Connect to the Azure Storage Blob Service
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
*  In this example, the storage account name is "chilkat".
lnSuccess = loRest.Connect("chilkat.blob.core.windows.net",lnPort,lnBTls,lnBAutoReconnect)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    CANCEL
ENDIF

*  Provide Azure Cloud credentials for the REST call.
loAzAuth = CreateObject('Chilkat.AuthAzureStorage')
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: 2021-08-06" header to be automatically added.
loAzAuth.XMsVersion = "2021-08-06"
lnSuccess = 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.

lcResponseStr = loRest.FullRequestNoBody("GET","/?restype=service&comp=properties")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAzAuth
    CANCEL
ENDIF

*  When successful, the Azure Storage service will respond with a 200 response code,
*  with an XML body.  
IF (loRest.ResponseStatusCode <> 200) THEN
    *  Examine the request/response to see what happened.
    ? "response status code = " + STR(loRest.ResponseStatusCode)
    ? "response status text = " + loRest.ResponseStatusText
    ? "response header: " + loRest.ResponseHeader
    ? "response body (if any): " + lcResponseStr
    ? "---"
    ? "LastRequestStartLine: " + loRest.LastRequestStartLine
    ? "LastRequestHeader: " + loRest.LastRequestHeader
    RELEASE loRest
    RELEASE loAzAuth
    CANCEL
ENDIF

*  Load the XML response for parsing.
*  An example of the response XML is shown below.
loXml = CreateObject('Chilkat.Xml')
lnSuccess = loXml.LoadXml(lcResponseStr)

? loXml.GetXml()

*  Use the ChilkatPath method to get various pieces of information out
*  of the XML.  For example:

? "Logging retention policy #days = " + loXml.ChilkatPath("Logging|RetentionPolicy|Days|*")
? "Hour metrics include APIs = " + loXml.ChilkatPath("HourMetrics|IncludeAPIs|*")

*  <?xml version="1.0" encoding="utf-8" ?>
*  <StorageServiceProperties>
*      <Logging>
*          <Version>1.0</Version>
*          <Read>true</Read>
*          <Write>true</Write>
*          <Delete>true</Delete>
*          <RetentionPolicy>
*              <Enabled>true</Enabled>
*              <Days>7</Days>
*          </RetentionPolicy>
*      </Logging>
*      <HourMetrics>
*          <Version>1.0</Version>
