Creates an Azure Service Bus Queue.

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

* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("<yournamespace>.servicebus.windows.net",443,1,lnBAutoReconnect)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    CANCEL
ENDIF

* ----------------------------------------------------------------------------------------------
* 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..
* ----------------------------------------------------------------------------------------------

* Let's load a previously computed SAS token and use it.
* See Azure Shared Access Signature for an example to genenerate an Azure SAS token.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbToken = CreateObject('Chilkat.StringBuilder')
loSbToken.LoadFile("qa_data/tokens/serviceBusSas.txt","utf-8")

* Tell the REST object to use the Azure Shared Access Signature for authorization.
loSbToken.Prepend("SharedAccessSignature ")
loRest.AddHeader("Authorization",loSbToken.GetAsString())

* ----------------------------------------------------------------------------------------------

* Create a new queue named "fox";
lcQueueName = "fox"

* Create the XML body of the PUT request.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
loXml = CreateObject('Chilkat.Xml')
loXml.Tag = "entry"
loXml.AddAttribute("xmlns","http://www.w3.org/2005/Atom")
loXml.UpdateAttrAt("title",1,"type","text")
loXml.UpdateChildContent("title",lcQueueName)
loXml.UpdateAttrAt("content",1,"type","application/xml")
loXml.UpdateAttrAt("content|QueueDescription",1,"xmlns:i","http://www.w3.org/2001/XMLSchema-instance")
loXml.UpdateAttrAt("content|QueueDescription",1,"xmlns","http://schemas.microsoft.com/netservices/2010/10/servicebus/connect")
loXml.EmitXmlDecl = 0
? loXml.GetXml()

* The XML created by the above code:

* 	<entry xmlns="http://www.w3.org/2005/Atom">
* 	    <title type="text">fox</title>
* 	    <content type="application/xml">
* 	        <QueueDescription xmlns:i="http://www.w3.org/2001/XMLSchema-instance" 
* 			xmlns="http://schemas.microsoft.com/netservices/2010/10/servicebus/connect" />
* 	    </content>
* 	</entry>

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbRequestBody = CreateObject('Chilkat.StringBuilder')
loXml.GetXmlSb(loSbRequestBody)

* The path should be set to the to-be-created queue name.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbPath = CreateObject('Chilkat.StringBuilder')
loSbPath.Append("/")
loSbPath.Append(lcQueueName)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponseBody = CreateObject('Chilkat.StringBuilder')
lnSuccess = loRest.FullRequestSb("PUT",loSbPath.GetAsString(),loSbRequestBody,loSbResponseBody)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loSbToken
    RELEASE loXml
    RELEASE loSbRequestBody
    RELEASE loSbPath
    RELEASE loSbResponseBody
    CANCEL
ENDIF

? "Response Status Code = " + STR(loRest.ResponseStatusCode)

* Check for a success response.
IF (loRest.ResponseStatusCode <> 201) THEN
    ? loRest.LastRequestStartLine
    ? loRest.LastRequestHeader
    ? loSbResponseBody.GetAsString()
    ? "Failed."
    RELEASE loRest
    RELEASE loSbToken
    RELEASE loXml
    RELEASE loSbRequestBody
    RELEASE loSbPath
    RELEASE loSbResponseBody
    CANCEL
ENDIF

* The response is XML.  (See a sample response below..)
loXml.LoadSb(loSbResponseBody,1)
? loXml.GetXml()

? "Success."
