Php 将新的传输驱动程序添加到Laravel'；s邮递员

我需要在Laravel的邮件包中添加一个新的传输驱动程序，这样我就可以通过默认不支持的外部服务（Mailjet）发送电子邮件

编写运输驱动程序不会是一个问题，但我找不到一种方法来连接并添加一个新的驱动程序，这样我就可以继续正常使用Laravel的mailer。我找不到任何关于扩展邮件程序的文档

我能想到的唯一方法是用我自己的服务提供商替换Laravel的

MailServiceProvider

在

config/app.php

中被引用的位置，然后我可以用它注册我自己的

TransportManager

和我自己的传输驱动程序

---

有没有更好的方法来添加另一个传输驱动程序？

我已经按照我在问题中建议的方式（通过编写我自己的

ServiceProvider

和

TransportManager

来允许我提供驱动程序）使它工作。这就是我为任何可能遇到这种情况的人所做的：

config/app.php-将Laravel的

MailServiceProvider

替换为我自己的

// ...
'providers' => [
    // ...

    // Illuminate\Mail\MailServiceProvider::class,
    App\MyMailer\MailServiceProvider::class,

    // ...

app/MyMailer/MailServiceProvider.php-创建一个服务提供商，扩展Laravel的

MailServiceProvider

，并覆盖

registerSwiftTransport（）

方法

<?php

namespace App\MyMailer;

class MailServiceProvider extends \Illuminate\Mail\MailServiceProvider
{
    public function registerSwiftTransport()
    {
        $this->app['swift.transport'] = $this->app->share(function ($app) {
            // Note: This is my own implementation of transport manager as shown below
            return new TransportManager($app);
        });
    }
}

app/MyMailer/Transport/mailjetttransport.php-我自己的传输驱动程序，通过Mailjet发送电子邮件

已更新以包含Mailjet传输驱动程序的我的实现。用作基础的

…这使我能够正常使用Laravel的mailer包（通过Facade或依赖项注入）：

\Mail::send('view', [], function($message) {
    $message->to('me@domain.com');
    $message->subject('Test');
});

是的，您必须创建自己的

Mailer

类。最好，你的类应该实现和接口。谢谢你的回复。仅仅为了能够为另一项服务添加我自己的驱动程序，这似乎有点过头了。我宁愿尽可能多地使用Laravel的功能。请参阅下面我的答案，了解到目前为止我是如何实现它的。最后，您让它工作了吗？也许使用MailJetAPI

mailjetttransport:：send（）

我还没有完成它的实现，但我以前已经实现了mailjetapi，所以我很有信心完成后它会工作。我会用Guzzle来达到他们的

发送

终点。谢谢你的提示，我也会试试。没问题。我可以在完成后更新我的答案。看看Laravel附带的

MailgunTransport

或

MandrillTransport

，它们会让您知道需要做什么。那太好了，我已经用过Guzzle，但任何帮助都可能对这里的每个人都有好处：）
