* 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>
*         <Enabled>true</Enabled>
*         <IncludeAPIs>true</IncludeAPIs>

*     </HourMetrics>
*     <MinuteMetrics>
*         <Version>1.0</Version>
*         <Enabled>false</Enabled>
*         <RetentionPolicy>
