Receive MessageCountDetails for a Subscription

[Shaked]

Hello,

I'm interested in receiving the MessageCountDetails from your API, as I see that it is possible to do by using the C# SDK)

Basically I'm trying to get the total count of dead letters per subscription.

AFAIU this should be possible: https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-dead-letter-queues#path-to-the-dead-letter-queue

Path to the dead-letter queue
You can access the dead-letter queue by using the following syntax:
/$deadletterqueue
/Subscriptions//$deadletterqueue
If you are using the .NET SDK, you can get the path to the dead-letter queue by using the SubscriptionClient.FormatDeadLetterPath() method. This method takes the topic name/subscription name and suffixes with /$DeadLetterQueue.

However, I could not figure how to get it using the PHP API.

Even when I manually edited the subscription path:

    public function getSubscription($topicPath, $subscriptionName) {
        $httpCallContext = new HttpCallContext();
        $httpCallContext->setMethod(Resources::HTTP_GET);
        $httpCallContext->addStatusCode(Resources::STATUS_OK);
        $subscriptionPath = sprintf(
            Resources::SUBSCRIPTION_PATH . '/$DeadLetterQueue/',
            $topicPath,
            $subscriptionName
        );
        $httpCallContext->setPath($subscriptionPath);
        $response = $this->sendHttpContext($httpCallContext);
        var_dump((string) $response->getBody());die;
        $subscriptionInfo = new SubscriptionInfo();
        $subscriptionInfo->parseXml($response->getBody());

        return $subscriptionInfo;
    }

I ended up with this message:

Bad Request\ndetails (if any): 400The specified HTTP verb (GET) is not valid. To know more visit https://aka.ms/sbResourceMgrExceptions. .

What can I do in order to get this information?

Thank you

After contacting Azure's support, it seems like that the PHP SDK is not updated and is not using the latest API version.

The ideal solution should be something like:

ServiceBusRestProxy.php

  public function getSubscription($topicPath, $subscriptionName) {
        $httpCallContext = new HttpCallContext();
        $httpCallContext->setMethod(Resources::HTTP_GET);
        $httpCallContext->addStatusCode(Resources::STATUS_OK);
        $subscriptionPath = sprintf(
            Resources::SUBSCRIPTION_PATH,
            $topicPath,
            $subscriptionName
        );
        $httpCallContext->setPath($subscriptionPath);
        $httpCallContext->setQueryParameters([
+            'api-version' => '2017-04',
        ]);
        $response = $this->sendHttpContext($httpCallContext);

Which will end up with a larger XML response:

Are you guys planning to upgrade this SDK at some point?

Thank you

EDIT:

I have started to work on a solution: master...Shaked:master (which I'm currently using).

However, I doubt I will have the time to follow this repository's guidelines, as it is way too complex and time consuming. Would have been nice to have an automated docker image for that part with a single entry point.
