* 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('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.

* 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('Chilkat.Xml')
loXml.Tag = "StorageServiceProperties"
loXLogging = loXml.NewChild("Logging","")
loXLogging.NewChild2("Version","1.0")
loXLogging.NewChild2("Delete","true")
loXLogging.NewChild2("Read","true")
loXLogging.NewChild2("Write","true")
loXRetension = loXLogging.NewChild("RetentionPolicy","")
loXRetension.NewChild2("Enabled","true")
loXRetension.NewChild2("Days","7")
RELEASE loXRetension
RELEASE loXLogging

* The expected response is a 202 response status code with no response body.
lcResponseStr = loRest.FullRequestString("PUT","/?restype=service&comp=properties",loXml.GetXml())
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAzAuth
    RELEASE loXml
    CANCEL
ENDIF

* When successful, the Azure Storage service will respond with a 202 response code,
* with no response body.
IF (loRest.ResponseStatusCode <> 202) 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
    RELEASE loXml
