## 序言

因为在项目中需要保存下发送的邮件内容，以便后续查看

## 代码

通过以下代码就会获取到：

```php
return Container::getInstance()->make('mailer')->render(
    $this->buildView(), $this->buildViewData()
);
```

完整代码实例：

```php
<?php

namespace App\Mail;

use App\Enums\Manage\MailSendLogTypeEnum;
use App\Models\BindingList;
use App\Models\MailSendLog;
use Illuminate\Bus\Queueable;
use Illuminate\Container\Container;
use Illuminate\Contracts\Container\BindingResolutionException;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use ReflectionException;
use Throwable;

/**
 * 用户额度不足充值提醒
 */
class InsufficientQuotaReminderMail extends Mailable
{
    use Queueable, SerializesModels;

public $subject = 'Recharge Reminder from Parcel Panel';

/**
     * Create a new message instance.
     *
     * @param \App\Models\BindingList           $bindingList
     * @param array{name:string, domain:string} $info
     */
    public function __construct(public BindingList $bindingList, public array $info)
    {
        $this->queue = 'account-send-email';
    }

/**
     * Build the message.
     *
     * @return $this
     */
    public function build(): static
    {
	    // 存放你的逻辑代码
        return $this->view('emails.account.insufficient_quota_reminder');
    }

/**
     * 处理任务成功
     *
     * @param \Illuminate\Contracts\Mail\Factory|\Illuminate\Contracts\Mail\Mailer $mailer
     */
    public function send($mailer)
    {
        parent::send($mailer);

$model = MailSendLog::whereId($this->mailSendLogId)->first();
        if (is_null($model)) return;

try {
            $model->content = $this->getRender();
        } catch (BindingResolutionException | ReflectionException) {
        }

$model->status = 1;//发送成功
        $model->save();
    }

/**
     * 处理任务失败。
     *
     * @param \Throwable $exception
     *
     * @return void
     */
    public function failed(Throwable $exception)
    {
        $model = MailSendLog::whereId($this->mailSendLogId)->first();
        if (is_null($model)) return;

try {
            $model->content = $this->render();
        } catch (ReflectionException) {
        }

$model->exception = $exception->getMessage();
        $model->status = 2;//发送失败
        $model->save();
    }

/**
	 * 获取渲染后的邮件模版
	 * 
     * @return string
     * @throws \Illuminate\Contracts\Container\BindingResolutionException
     * @throws \ReflectionException
     */
    private function getRender(): string
    {
        return Container::getInstance()->make('mailer')->render(
            $this->buildView(), $this->buildViewData()
        );
    }
}

```
