我已经将Lumen 5.4.6配置为使用Mailgun发送电子邮件。我看到了其他几个答案，但它们不完整或有不必要的陈述，或者它们比需要的更复杂。
我在下面提供了完整而详细的步骤，以便让Lumen与Mailgun一起使用，就像我发现的那样简单明了。
如果您了解更简单，更清洁，更优雅的方式，请添加您的答案和评论。

更新：我正在开发一个开源的快速启动样板流明项目，其中包含一些开箱即用的有用功能 通过电子邮件发送以及用户注册和登录： https://github.com/AMS777/ams-bl
它可以用作JSON API流明项目的起点，也可以作为所述步骤的参考 下面。在那里，您还可以找到一些注释，以便在浏览器上测试和预览电子邮件。
在命令行上添加Laravel的Composer包：
composer require illuminate/mail
composer require guzzlehttp/guzzle
我使用的是Lumen 5.4.6，因此我必须安装一个旧的mail包：
composer require illuminate/mail:5.4.*
在档案bootstrap/app.php上添加：
bootstrap / app.php： （Register Service Providers部分。）
$app->register(\Illuminate\Mail\MailServiceProvider::class);
bootstrap / app.php： （在文件末尾，return上方。）
$app->configure('services');
$app->configure('mail');
如果您想使用简易界面Facades发送电子邮件，则必须取消注释：
bootstrap / app.php： （取消注释。）
$app->withFacades();
在项目中创建以下文件：
config/mail.php config/services.php 复制并安排Laravel文件的内容：
https://github.com/laravel/laravel/blob/master/config/mail.php
这里我已将默认邮件驱动程序更改为mailgun。 username和password未与mailgun驱动程序一起使用，可能会将其删除。
<强>配置/ mail.php：
<?php
return [
/*

| Mail Driver

|
| Supported: "smtp", "sendmail", "mailgun", "mandrill", "ses",
| "sparkpost", "log", "array"
|
*/
'driver' => env('MAIL_DRIVER', 'mailgun'),
/*
|--------------------------------------------------------------------------
| SMTP Host Address
|--------------------------------------------------------------------------
|
| Here you may provide the host address of the SMTP server used by your

|
*/
'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
/*
|--------------------------------------------------------------------------
| SMTP Host Port
|--------------------------------------------------------------------------
|
| This is the SMTP port used by your application to deliver e-mails to
| users of the application. Like the host we have set this value to
| stay compatible with the Mailgun e-mail application by default.
|
*/
'port' => env('MAIL_PORT', 587),
/*
|--------------------------------------------------------------------------
| Global "From" Address
|--------------------------------------------------------------------------
|
| You may wish for all e-mails sent by your application to be sent from
| the same address. Here, you may specify a name and address that is
| used globally for all e-mails that are sent by your application.
|
*/
'from' => [
'address' => env('MAIL_FROM_ADDRESS', 'hello@example.com'),
'name' => env('MAIL_FROM_NAME', 'Example'),
],
/*
|--------------------------------------------------------------------------
| E-Mail Encryption Protocol
|--------------------------------------------------------------------------
|
| Here you may specify the encryption protocol that should be used when
| the application send e-mail messages. A sensible default using the
| transport layer security protocol should provide great security.
|
*/
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
/*
|--------------------------------------------------------------------------
| SMTP Server Username
|--------------------------------------------------------------------------

'username' => env('MAIL_USERNAME'),
'password' => env('MAIL_PASSWORD'),
/*
|--------------------------------------------------------------------------
| Sendmail System Path

*/
'sendmail' => '/usr/sbin/sendmail -bs',
/*

| Markdown Mail Settings

|
| If you are using Markdown based email rendering, you may configure your

'markdown' => [
'theme' => 'default',
'paths' => [
resource_path('views/vendor/mail'),
],
],
];
https://github.com/laravel/laravel/blob/master/config/services.php
我在这里删除了不必要的行。
<强>配置/ services.php：
<?php
return [
/*
|--------------------------------------------------------------------------
| Third Party Services
|--------------------------------------------------------------------------
|
| This file is for storing the credentials for third party services such
| as Stripe, Mailgun, SparkPost and others. This file provides a sane
| default location for this type of information, allowing packages
| to have a conventional place to find your various credentials.
|
*/
'mailgun' => [
'domain' => env('MAILGUN_DOMAIN'),
'secret' => env('MAILGUN_SECRET'),
],
];
然后，您需要在.env文件中设置环境变量：
<强> .ENV：
MAIL_DRIVER=mailgun
MAIL_HOST=smtp.mailgun.org
MAIL_PORT=587
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=your@email.es
MAIL_FROM_NAME="Your email sender name"
MAILGUN_DOMAIN=sandbox_EXAMPLE.mailgun.org
MAILGUN_SECRET=key-EXAMPLE
嗯，到目前为止，Lumen已准备好电子邮件功能。
设置邮件功能后，在Lumen中创建和发送电子邮件的步骤与Laravel相同，可以在其文档中查看：
https://laravel.com/docs/5.4/mail
要在Lumen发送电子邮件，您需要3个文件：
Mailable。从视图构建电子邮件。此邮件类示例仅导入构建电子邮件所需的包。如果要使用队列，则需要导入更多包。
应用/邮件/ RegisterConfirmationEmail.php：
<?php
namespace App\Mail;
use Illuminate\Mail\Mailable;
class RegisterConfirmation extends Mailable
{
/**
* Build the message.
*
* @return $this
*/
public function build()
{
return $this->view('RegisterConfirmationEmail');
}
}
在5.2版本的Lumen中删除了视图，但很快就恢复了。截至Lumen 5.4视图工作，但文档上没有任何线索。
如果您不想使用视图，可以使用raw()函数。
<强>资源/视图/ RegisterConfirmationEmail.blade.php：
<html>
<body>
<h1>Test</h1>
</body>
</html>
发送电子邮件的类必须导入邮件类。请记住，此示例使用Facade接口，必须在bootstrap/app.php上启用。
应用/ HTTP /控制器/ RegisterController.php：
<?php
namespace App\Http\Controllers;
use App\Mail\RegisterConfirmation;
use Illuminate\Support\Facades\Mail;
class RegisterController extends Controller
{
public function sendRegisterConfirmationEmail()
{
Mail::to('test+receiver@email.es')->send(new RegisterConfirmation());
}
}
在Mailgun上，您必须使用您和您公司的一些数据创建一个帐户。
Mailgun会要求您提供手机号码以继续进行帐户验证：
“为了防止滥用行为，Mailgun要求您通过验证帐户 使用短信。“
对于开发帐户，不需要信用卡或域名验证，但您最多需要授权5个电子邮件地址。
您可以使用Mailgun提供的沙箱域。
