* Azure Blob Service Example: Get Blob Service Stats

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
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".
* ---- IMPORTANT ----
* The "-secondary" suffix is required.
* This requires an Azure storage account with replication set to "Read-access geo-redundant storage (RA-GRS)"
* If you made the change just prior to testing this example, you'll need to give it time for the 
* DNS to become available..  
* ---- IMPORTANT ----
lnSuccess = loRest.Connect("chilkat-secondary.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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.AuthAzureStorage')
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=stats")
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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
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:

? "Status = " + loXml.ChilkatPath("GeoReplication|Status|*")
lcLastSyncTimeStr = loXml.ChilkatPath("GeoReplication|LastSyncTime|*")
? "LastSyncTime = " + lcLastSyncTimeStr

* The date/time string can be loaded into a CkDateTime object for 
* access to individual parts, or conversion to other formats.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.CkDateTime')
loDateTime = CreateObject('Chilkat.CkDateTime')
lnSuccess = loDateTime.SetFromRfc822(lcLastSyncTimeStr)

* For example:
lnBLocalTime = 1
loDt = loDateTime.GetDtObj(lnBLocalTime)
? STR(loDt.Year) + "/" + STR(loDt.Month) + "/" + STR(loDt.Day)
RELEASE loDt
