(JavaScript) Azure Blob Service - List all Containers in a Storage Account

Azure Storage Blob Service REST API: Lists all the containers in a storage account.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// Azure Blob Service Example: List all of the containers in an account.

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

var rest = new CkRest();

var bTls = true;
var port = 443;
var bAutoReconnect = true;

// The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = "chilkat";
azAuth.Scheme = "SharedKey";

// This causes the "x-ms-version: 2021-08-06" header to be automatically added.

// URI parameters, such as "maxresults", are added by calling AddQueryParam
success = rest.AddQueryParam("maxresults","1000");

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

// with an XML body.
