如何使用Laravel 5.1获取IronMQ中的排队作业数？

Question

Implementing queues & jobs in Laravel 5.1 in my project using IronMQ, I can now send jobs to the IronMQ queue like you see in image bellow :

What I want now is to get the current number of messages in queue (number in red box) in the handle function in my job, find job code bellow :

class GetWords extends Job implements SelfHandling, ShouldQueue{
use InteractsWithQueue, SerializesModels;


    /**
     * Create a new job instance.
     */
    public function __construct(Url $url)
    {
    }

    /**
     * Execute the job.
     */
    public function handle()
    {
        //getting the name of queue
        dd($this->job->getName()); //return 'words'

        $currentNumberMsgsInQueue = ?????; //i can't find how

        //Condition
        if($currentNumberMsgsInQueue == 10){
            //Do something
        }
    }
}

Question is : How to get number of queued jobs (messages) in IronMQ queue using Laravel ?

Answer 1

After days of searching I found the answer, there's no method/function in Laravel 5.1 that can give us the number of queued jobs in IronMQ.

But against IronMQ On-Premise API Reference give us a solution, it's a REST/HTTP API that allow us to query different requests using javascript to set/get all what we want from/to queue (Get Queue, Update Queue, List Queues ...) and from/to messages in every queue (Get Message by Id, Get all Messages, Clear Messages ...).

Base URL :

https://{Host}/{API Version}/projects/{Project_ID}/queues/{Queue_Name}/messages/webhook?oauth={Token}

Example, if we want the number of messages in queue, we have just to Get Queue Info and peek the size from result.

GET /queues/{Queue Name}

---

A Practical Example :

You can find your first base link inside the concerned queue in your project under Webhook URL case (see picture bellow) :

JS code :

//To get queue info we have url : GET /queues/{Queue Name}
var url = "https://{Host}/{API Version}/projects/{Project_ID}/queues/{Queue_Name}?oauth={Token}";

//Using ajax $.get
$.get( url ,
function( result ) {
     alert( "Queue size is :" + result["queue"]["size"]);
});

Result :

{
  "queue": {
    "project_id": 123,
    "name": "my_queue",
    "size": 0,
    "total_messages": 0,
    "message_timeout": 60,
    "message_expiration": 604800,
    "type": "pull/unicast/multicast",
    "push": {
      "subscribers": [
        {
          "name": "subscriber_name",
          "url": "http://mysterious-brook-1807.herokuapp.com/ironmq_push_1",
          "headers": {
            "Content-Type": "application/json"
          }
        }
      ],
      "retries": 3,
      "retries_delay": 60,
      "error_queue": "error_queue_name",
      "rate_limit": 10
    }
  }
}
