Question

我正在使用laravel-excel软件包，并且DB中有30,000多种产品，我需要对数据进行排队，然后将最终文件发送到电子邮件中，以通知用户该文件已准备好下载通过电子邮件！

记录到this：

  (new ExportProducts(merchant()->id))->queue('products.xlsx')->chain([
         // how to send the file to job ?
         //new NotifyMerchantFileExport(request()->user()),
  ]);

排队完成后，有什么方法可以将文件发送到电子邮件吗？

Answer 1

遵循以下结构：

在您的_globalHook = Hook.GlobalEvents(); _globalHook.KeyPress += GlobalHookKeyPress; //Subscribe _globalHook.KeyPress -= GlobalHookKeyPress; //Unsubscribe类中，请确保using System; using System.Windows.Forms; using System.Diagnostics; using System.Reactive.Linq; using Gma.System.MouseKeyHook; using MouseKeyHook.Rx; namespace HotkeyPlay { public partial class Form1 : Form { private IDisposable _keysObservable; public Form1() { InitializeComponent(); var triggers = new Trigger[] { Trigger.On(Keys.H).Alt().Shift() }; _keysObservable = Hook .GlobalEvents() .KeyDownObservable() .Matching(triggers) .Subscribe((trigger) => { Debug.WriteLine(trigger.ToString()); }); } private void button1_Click(object sender, EventArgs e) { _keysObservable.Dispose(); var triggers = new Trigger[] { Trigger.On(Keys.B).Alt().Shift() }; _keysObservable = Hook .GlobalEvents() .KeyDownObservable() .Matching(triggers) .Subscribe((trigger) => { Debug.WriteLine(trigger.ToString()); }); } } }。

Install-Package System.Reactive.Linq
Install-Package MouseKeyHook.Rx

可能是这样的：
```
ExportProducts
```
创建新工作，我将其称为implements ShouldQueue：
```
FooController
```
创建一个新的电子邮件文件<?php namespace App\Http\Controllers; use App\Exports\ExportProducts; use App\Http\Controllers\Controller; use App\Jobs\Export\NotifyMerchantOfCompleteFileExport; class FooController extends Controller { public function index() { $fileName = 'uploads/excel-files/'.Str::random(3).'.xlsx'; $filePath = asset($fileName); (new ExportProducts)->store($fileName,'public')->chain([ new NotifyUserOfCompleteFileExport(auth()->user(),$filePath), ]);; return back()->withSuccess('export started')); } }：
```
NotifyUserOfCompleteFileExport
```

说明步骤2

只需将您需要下载的最终文件存储在内部队列完成后，公共<?php namespace App\Jobs; use Illuminate\Bus\Queueable; use Illuminate\Support\Facades\Mail; use Illuminate\Queue\SerializesModels; use Illuminate\Queue\InteractsWithQueue; use App\Mail\Merchant\CompleteExportedFile; use Illuminate\Contracts\Queue\ShouldQueue; use Illuminate\Foundation\Bus\Dispatchable; class NotifyUserOfCompleteFileExport implements ShouldQueue { use Dispatchable, InteractsWithQueue, Queueable, SerializesModels; public $user; public $filePath; public function __construct($user,$filePath) { $this->user = $user; $this->filePath = $filePath; } public function handle() { Mail::to($this->user)->send(new CompleteExportedFile($this->filePath)); } }将此文件的目录传递到作业文件CompleteExportedFile，然后再次向用户发送电子邮件以及该文件的路径，最后，您可以为该文件创建一个新刀片您的电子邮件，然后将文件路径放入html标签：

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class CompleteExportedFile extends Mailable implements ShouldQueue
{
    use Queueable, SerializesModels;

    public $filePath;

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

    public function build()
    {
        return $this->subject('File has been exported')
                ->markdown('emails.send-export-file');
    }
}
