(PHP Extension) How to Generate an Azure Storage Account Shared Access Signature (SAS)Shows how to generate a Shared Access Signature (SAS) for an Azure Storage Account. Note: This example requires Chilkat v9.5.0.65 or greater.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // Note: Requires Chilkat v9.5.0.65 or greater. // 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 Storage Account. // -------------------------------------------------------------------------- // See https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/constructing-an-account-sas // for details regarding the Azure Storage Account SAS fields. $authSas = new CkAuthAzureSAS(); $authSas->put_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. $authSas->put_StringToSign('accountname,signedpermissions,signedservice,signedresourcetype,signedstart,signedexpiry,signedIP,signedProtocol,signedversion,'); // The account name is "chilkat". Use your own account name instead of "chilkat". // Also use your own container name instead of "mycontainer". $authSas->SetNonTokenParam('accountname','chilkat'); $authSas->SetTokenParam('signedpermissions','sp','rwdlacup'); $authSas->SetTokenParam('signedservice','ss','bfqt'); $authSas->SetTokenParam('signedresourcetype','srt','sco'); $dt = new CkDateTime(); $dt->SetFromCurrentSystemTime(); $authSas->SetTokenParam('signedstart','st',$dt->getAsIso8601('YYYY-MM-DDThh:mmTZD',false)); // This SAS token will be valid for 30 days. $dt->AddDays(30); $authSas->SetTokenParam('signedexpiry','se',$dt->getAsIso8601('YYYY-MM-DDThh:mmTZD',false)); $authSas->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. $authSas->SetTokenParam('signedversion','sv','2015-04-05'); // Note that we did not call SetTokenParam for "signedIP". For any omitted fields // the value will default to the empty string. // Generate the SAS token. $sasToken = $authSas->generateToken(); if ($authSas->get_LastMethodSuccess() != true) { print $authSas->lastErrorText() . "\n"; exit; } print 'SAS token: ' . $sasToken .
