How to notify the user that a job has completed in Laravel?
提问by rrrafalsz
in Laravel, you can use jobsto execute tasks in a back-end queue while the rest of the application does other things. i have a job that is initiated by user input. immediately, through javascript, i give the user a notification that the job is being processed.
在 Laravel 中，您可以使用作业在后端队列中执行任务，而应用程序的其余部分则做其他事情。我有一个由用户输入启动的工作。立即，通过 javascript，我向用户通知正在处理作业。
i would like to be able to give a similar notification after the job has successfully completed.
我希望能够在工作成功完成后发出类似的通知。
i am calling my job from within a model like this:
我从这样的模型中调用我的工作：
public function doSomething() {
$job = new \App\Jobs\MyJob();
app('Illuminate\Contracts\Bus\Dispatcher')->dispatch($job);
}
and this is how my job headers look like:
这就是我的工作标题的样子：
class MyJob extends Job implements SelfHandling, ShouldQueue
{
use InteractsWithQueue, SerializesModels, Queueable;
...
}
the model job call is actually triggered from a controller method:
模型作业调用实际上是从控制器方法触发的：
public function getDoSomething($id) {
$item = Item::findOrFail($id);
$item->doSomething();
return response()->json(true);
}
which is handled by an AJAX call:
这是由 AJAX 调用处理的：
$.ajax({
url: $(this).attr('href'),
type: 'GET',
dataType: 'json',
success: $.proxy(function(result) {
this.application.notification.showMessage('Job is being processed.');
}, this),
error: $.proxy(function(result) {
console.error(result);
}, this)
});

Probably I'm late for the party guys, but there are several options i can think of. When user clicks button from the front-end you can give attribute disabled to it and some text like 'processing'. Then you can:
可能我参加派对迟到了，但我能想到几个选择。当用户从前端单击按钮时，您可以为其设置禁用属性和一些文本，如“处理”。然后你可以：
- Just ping your endpoint to check if what job is performing is finished
- Use websockets
- 只需 ping 您的端点即可检查正在执行的作业是否已完成
- 使用网络套接字
I think Forge is doing websockets using pusher the endpoint to see if server is active when you are trying to deploy new code. I can clearly see the communication if you open Devtools->Resources->Sockets.
我认为 Forge 正在使用 pusher 端点执行 websockets，以查看当您尝试部署新代码时服务器是否处于活动状态。如果你打开 Devtools->Resources->Sockets，我可以清楚地看到通信。

You can use queue events, Laravel document explains it: https://laravel.com/docs/5.6/queues#job-events
你可以使用队列事件，Laravel 文档解释了它：https://laravel.com/docs/5.6/queues#job-events

You can user Queue::after function on your AppServiceProvider
您可以在 AppServiceProvider 上使用 Queue::after 函数
Import this dependencies
导入这个依赖
use Illuminate\Support\Facades\Queue;
use Illuminate\Queue\Events\JobProcessed;
use Illuminate\Queue\Events\JobProcessing;
And on boot method you would use it
在引导方法中，您将使用它
public function boot()
{
Queue::before(function (JobProcessing $event) {
// $event->connectionName
// $event->job
// $event->job->payload()
});
Queue::after(function (JobProcessed $event) {
// $event->connectionName
// $event->job
// $event->job->payload()
});
}

Job Completion Event
作业完成事件
The Queue::aftermethod allows you to register a callback to be executed when a queued job executes successfully. This callback is a great opportunity to perform additional logging, queue a subsequent job, or increment statistics for a dashboard.
该Queue::after方法允许您注册在排队作业成功执行时要执行的回调。此回调是执行额外日志记录、将后续作业排队或增加仪表板统计信息的绝佳机会。
