* Azure Blob Service Example: Delete Container
* See also: https://msdn.microsoft.com/en-us/library/azure/dd179408.aspx

* 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".
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.
* 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.

* To call Delete Container on a container that has an active lease, specify the lease ID in this header. 
* If this header is not specified when there is an active lease, Delete Container will return 409 (Conflict). 
* If you specify the wrong lease ID, or a lease ID on a container that does not have an active lease, 
* Delete Container will return 412 (Precondition failed).

* IMPORTANT: Delete this line, or insert a valid lease ID, otherwise the request
* will fail with a 400 status code..
lnSuccess = loRest.AddHeader("x-ms-lease-id","SOME_LEASE_ID")

* The expected success response is a 202 response status code with no response body.
* In this example, the container to be deleted is named "mycontainer".
lcResponseStr = loRest.FullRequestNoBody("DELETE","/mycontainer?restype=container")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAzAuth
    CANCEL
ENDIF

* When successful, the Azure Storage service will respond with a 202 response code,
* with no response body.

* If the container with the same name already exists, then the operation will fail.
IF (loRest.ResponseStatusCode <> 202) THEN
    * Examine the request/response to see what happened.
