将存储库接口实现到作业中

Question

I am trying to implement an Interface into a Job but having no luck. Is it possible to implement an interface / repository within the public construct and use said interface in the handle() method of the Job?

The error I am getting is as follows:

Argument 1 passed to App\Jobs\OrderCreate::__construct() must be an instance of App\Http\Interfaces\OrderInterface, string given, called in /Users/Panoply/Sites/stock-sync/app/Http/Controllers/StockController.php on line 31

Below is a basic setup of what I am trying to achieve.

Stock Controller:

public function test(){
   dispatch(new OrderCreate('hello'));
}

OrderCreate Job:

protected $order;
protected $test;

public function __construct(OrderInterface $order, $test)
{
    $this->order = $order;
    $this->test = $test;
}

public function handle()
{
    $this->order->test($this->test);
}

OrderRepository:

class OrderRepository implements OrderInterface
{
    public function test($data) {
        error_log($data);
    }
}

OrderInterface:

public function test($data);

I have had no troubles implementing this pattern into my controllers and commands but I can't seem to get it working on a Job.

Nevermind, the issue was I shouldn't of been calling the interface within the __construct() but instead within handle()

Editing for more detailed explanation.

The __construct() of a Laravel / Lumen Job from what I can tell only accepts data and thus implementing an interface within the __constuct() will cause my above error to be thrown.

In order to use an Interface within a job, you will need to call your interface within the handle() function.

As an example, the following will NOT work within a Job class:

protected $test;

public function __construct(InterfaceTest $test)
{
     $this->test = $test;
}

This is because the Job construct does not take in Interfaces, it only takes in the data you pass in from the dispatch call. In order to use your Interface within a job, you need to call the interface within the handle() function and then it will succeed and work, example:

public function handle(InterfaceTest $test)
{
     $test->fn();
}

This seems to only be the case when implementing on a Job. In most cases when you require an interface within a Controller or Command, you will implement within the __construct().
