Php 使用laravel excel从数据库导出大型数据？

我正在使用软件包，我在

DB

中有30000多个产品，我需要将数据排队，然后将最终文件发送到电子邮件，通知用户该文件已准备好从电子邮件下载

录制到：

排队完成后，有没有办法将文件发送到电子邮件？

遵循以下结构：

在您的

ExportProducts

类中，确保

实现ShouldQueue

在控制器中，控制器可能是这样的：

<?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'));
    }
}

创建新的电子邮件文件

CompleteExportedFile

：

<?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');
    }
}

希望有用：）

<?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));
    }
}

<?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');
    }
}
