#  Azure File Service Example: List all the file shares in a storage account.
#  See also: https://docs.microsoft.com/en-us/rest/api/storageservices/list-shares

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

set rest [new_CkRest]

#  Connect to the Azure Storage Blob Service
set bTls 1
set port 443
set bAutoReconnect 1
#  In this example, the storage account name is "chilkat".

set success [CkRest_SetAuthAzureStorage $rest $azAuth]

#  Note: The application does not need to explicitly set the following
#  headers: x-ms-date, Authorization.  These headers
#  are automatically set by Chilkat.

#  Send the GET request to list the shares.

#  with an XML response body.
