(JavaScript) Azure Service Bus - Create Topic

Creates an Azure Service Bus Topic.

Note: This example requires Chilkat v9.5.0.65 or greater.

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;

// 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.

// Make the initial connection.
// A single REST object, once connected, can be used for many Azure Service Bus REST API calls.
// The auto-reconnect indicates that if the already-established HTTPS connection is closed,
// then it will be automatically re-established as needed.
var rest = new CkRest();

success = rest.Connect("<yournamespace>.servicebus.windows.net",443,true,bAutoReconnect);

    return;
}

// ----------------------------------------------------------------------------------------------
// The code above this comment could be placed inside a function/subroutine within the application
// because the connection does not need to be made for every request.  Once the connection is made
// the app may send many requests..

// See Azure Shared Access Signature for an example to genenerate an Azure SAS token.

// Tell the REST object to use the Azure Shared Access Signature for authorization.
