* Azure Blob Service Example: Get Container ACL
* See also: https://msdn.microsoft.com/en-us/library/azure/dd179469.aspx

* 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 = 0) 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.

* The expected success response is a 200 response status code with an XML response body.
* In this example, we are getting the ACL permissions of the container named "mycontainer".
lcResponseStr = loRest.FullRequestNoBody("GET","/mycontainer?restype=container&comp=acl")
IF (loRest.LastMethodSuccess = 0) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAzAuth
    CANCEL
ENDIF

* When successful, the Azure Storage service will respond with a 200 response status code,
* with an XML response 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:

? "Id = " + loXml.ChilkatPath("SignedIdentifier|Id|*")
lcStartTimeStr = loXml.ChilkatPath("SignedIdentifier|AccessPolicy|Start|*")
? "Start Time = " + lcStartTimeStr

* The date/time string can be loaded into a CkDateTime object for 
* access to individual parts, or conversion to other formats.
loDateTime = CreateObject('Chilkat.CkDateTime')
lnSuccess = loDateTime.SetFromTimestamp(lcStartTimeStr)

* For example..
lnBLocalTime = 1
loDt = CreateObject('Chilkat.DtObj')
loDateTime.ToDtObj(lnBLocalTime,loDt)

? STR(loDt.Year) + "/" + STR(loDt.Month) + "/" + STR(loDt.Day)

* <?xml version="1.0" encoding="utf-8" ?>
* <SignedIdentifiers>
*     <SignedIdentifier>
*         <Id>46KdrjGoh6bEJVbbLAKSVDLH3bBcjPKn</Id>
*         <AccessPolicy>
*             <Start>2016-05-04T22:10:49.0000000Z</Start>
*             <Expiry>2017-05-04T22:10:49.0000000Z</Expiry>
*             <Permission>rwd</Permission>
*         </AccessPolicy>
*     </SignedIdentifier>
