Create an Azure Service SAS

Shows how to generate an Azure Service SAS. AutoIt

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

;  ----------------------------------------------------------------------------------------------
;  Create a Shared Access Signature (SAS) token for an Azure Service (Blob, Queue, Table, or File)
;  -----------------------------------------------------------------------------------------------

;  See https://docs.microsoft.com/en-us/rest/api/storageservices/create-service-sas
;  for details.

$oAuthSas = ObjCreate("Chilkat.AuthAzureSAS")
$oAuthSas.AccessKey = "AZURE_ACCESS_KEY"

;  Specify the format of the string to sign.
;  Each comma character in the following string represents a LF ("\n") character.
;  The names specified in the StringToSign are replaced with the values specified
;  in the subsequent calls to SetTokenParam and SetNonTokenParam,.

;  Note: The trailing comma in the StringToSign is intentional and important. This indicates that the 
;  string to sign will end with a "\n".

;  Also note: The names in the StringToSign are case sensitive.  The names
;  specified in the 1st argument in the calls to SetNonTokenParam and SetTokenParam should
;  match a name listed in StringToSign. 

;  Version 2018-11-09 and later
;  
;  Version 2018-11-09 adds support for the signed resource and signed blob snapshot time fields. 
;  These must be included in the string-to-sign. To construct the string-to-sign for Blob service resources, use the following format:
;  
;  StringToSign = signedpermissions + "\n" +  
;                 signedstart + "\n" +  
;                 signedexpiry + "\n" +  
;                 canonicalizedresource + "\n" +  
;                 signedidentifier + "\n" +  
;                 signedIP + "\n" +  
;                 signedProtocol + "\n" +  
;                 signedversion + "\n" +  
;                 signedResource + "\n"
;                 signedSnapshotTime + "\n" +
;                 rscc + "\n" +  
;                 rscd + "\n" +  
;                 rsce + "\n" +  
;                 rscl + "\n" +  
;                 rsct  
;  

$oAuthSas.StringToSign = "signedpermissions,signedstart,signedexpiry,canonicalizedresource,signedidentifier,signedIP,signedProtocol,signedversion,signedResource,signedSnapshotTime,rscc,rscd,rsce,rscl,rsct"

$oAuthSas.SetTokenParam("signedpermissions","sp","rw")

$oDt = ObjCreate("Chilkat.CkDateTime")
$oDt.SetFromCurrentSystemTime()
$oAuthSas.SetTokenParam("signedstart","st",$oDt.GetAsIso8601("YYYY-MM-DDThh:mmTZD",False))

;  This SAS token will be valid for 30 days.
$oDt.AddDays(30)
$oAuthSas.SetTokenParam("signedexpiry","se",$oDt.GetAsIso8601("YYYY-MM-DDThh:mmTZD",False))

;  The canonicalizedresouce portion of the string is a canonical path to the signed resource. It must include the service name (blob, table, queue or file) for version
;  2021-08-06 or later, the storage account name, and the resource name, and must be URL-decoded. Names of blobs must include the blob�s container. Table names must be
;  lower-case. The following examples show how to construct the canonicalizedresource portion of the string, depending on the type of resource.
;  For example:
;  URL = https://chilkat.blob.core.windows.net/mycontainer/starfish.jpg
;  canonicalizedresource = "/blob/chilkat/mycontainer/starfish.jpg"  
;  IMPORTANT: See https://docs.microsoft.com/en-us/rest/api/storageservices/create-service-sas for all details..
$oAuthSas.SetNonTokenParam("canonicalizedresource","/blob/chilkat/mycontainer/starfish.jpg")

$oAuthSas.SetTokenParam("signedProtocol","spr","https")

;   Specifiy values and query param names for each field.
;   If a field is not specified, then an empty string will be used for its value.
$oAuthSas.SetTokenParam("signedversion","sv","2018-11-09")

;  Indicate that we are creating a service SAS that is limited to the blob resource.
;  (Specify b if the shared resource is a blob. This grants access to the content and metadata of the blob.
;   Specify c if the shared resource is a container. This grants access to the content and metadata of any blob in the container, and to the list of blobs in the container. )
$oAuthSas.SetTokenParam("signedResource","sr","b")

;  Note that we did not call SetTokenParam for "signedIP", "signedSnapshotTime", "rscc", and others.  For any omitted fields
;  the value will default to the empty string.

;  Generate the SAS token.
Local $sasToken = $oAuthSas.GenerateToken()
If ($oAuthSas.LastMethodSuccess <> True) Then
    ConsoleWrite($oAuthSas.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite("SAS token: " & $sasToken & @CRLF)

;  Save the SAS Service token to a file.
;  We can then use this pre-generated token for future Azure Storage Account operations.
