Laravel Mix 判断是否为生产环境

有这么个需求，需要在一些静态文件带上 hash 参数，解决 CDN 缓存问题，但是在网上找的用这个 `mix.config.production` 是会报错的

然后自己打印 `mix` 发现了一个 `inProduction()` 方法，验证了下，这个确实是判断是否为生产环境的

#### 修改项目根目录下 webpack.mix.js

```js
const mix = require('laravel-mix');

mix.js('resources/js/app.js', 'public/js')
  .postCss('resources/css/app.css', 'public/css', [
    require("tailwindcss"),
  ]);

if (mix.inProduction()) mix.version();

```

#### 然后看 /public/mix-manifest.json 会发现内容是这样的

```json
{
    "/js/app.js": "/js/app.js?id=33663d66c33666962f26",
    "/css/app.css": "/css/app.css?id=7066f8a66603866e666"
}
```

#### 只要你保证在你的  blade 模版里面使用如 `mix('js/app.js')` 这样引用的就没有问题

```blade
<!doctype html>
<html lang="{{ config('app.locale') ?? 'en' }}">
<head>
    <title>@yield('title')</title>
    <meta charset="UTF-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    <link href="{{ mix('css/app.css') }}" rel="stylesheet">
    <meta name="description" content="@yield('description')" />
    <meta name="keywords" content="@yield('keywords', 'ParcelPanel')" />
</head>
<body>

<div>
    @yield('content')
</div>

#### 最终生成的代码是类似 `<script src="/js/app.js?id=33663d66c33666962f26"></script>` 这样的

## 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()
        );
    }
}

```

PHP 对象动态传参数(反射) / Laravel Cast 的相关使用用例

## 序言

主要在用到 Laravel Cast，所以有了这个想法，暂时记录下用法，后面再慢慢解释（如果有空 哈哈哈哈）

## 代码

`MailSendLogComment.php`
```php
<?php
declare(strict_types=1);

namespace App\Casts\Manage;

class MailSendLogComment
{
    public function __construct(public string $test)
    {
    }

public function toArray(): array
    {
        return [
            'test' => $this->test
        ];
    }
}

```

`MailSendLogCommentCast.php`:
```php
<?php

namespace App\Casts\Manage;

use Illuminate\Contracts\Database\Eloquent\CastsAttributes;
use JetBrains\PhpStorm\Pure;
use ReflectionClass;

class MailSendLogCommentCast implements CastsAttributes
{
    /**
     * Cast the given value.
     *
     * @param \Illuminate\Database\Eloquent\Model $model
     * @param string                              $key
     * @param mixed                               $value
     * @param array                               $attributes
     *
     * @return mixed|object
     * @throws \ReflectionException
     */
    #[Pure]
    public function get($model, $key, $value, array $attributes)
    {
        if ($key !== 'comment') {
			// 看这里，用到了反射
            return (new ReflectionClass(MailSendLogComment::class))->newInstanceArgs(json_decode($value, true));
        }

return $value;
    }

/**
     * Prepare the given value for storage.
     *
     * @param \Illuminate\Database\Eloquent\Model $model
     * @param string                              $key
     * @param mixed                               $value
     * @param array                               $attributes
     *
     * @return array
     */
    public function set($model, $key, $value, array $attributes): array
    {
        if ($key === 'comments') {
            // 如果给的值不是 MailSendLogComment 对象就报错
            if ($value instanceof MailSendLogComment) {
                throw new InvalidArgumentException('The given value is not an ' . MailSendLogComment::class . ' instance.');
            }
            $attributes['comments'] = json_encode($value->toArray(), JSON_UNESCAPED_UNICODE);
        }

return $attributes;
    }
}

```

`MailSendLog.php`
```php
<?php

namespace App\Models;

use App\Casts\Manage\MailSendLogCommentCast;
use App\Enums\Manage\MailSendLogTypeEnum;
use Dcat\Admin\Traits\HasDateTimeFormatter;
use Illuminate\Database\Eloquent\Model;

/**
 * 邮件发送日志表
 * \App\Models\MailSendLog
 *

 * @property string                          $from_name  发送人名字
 * @property string                          $to_email   接收人邮箱
 * @property string                          $to_name    接收人名字

 * @method static \Illuminate\Database\Eloquent\Builder|MailSendLog whereToEmail($value)
 * @method static \Illuminate\Database\Eloquent\Builder|MailSendLog whereToName($value)
 * @method static \Illuminate\Database\Eloquent\Builder|MailSendLog whereType($value)
 * @method static \Illuminate\Database\Eloquent\Builder|MailSendLog whereUpdatedAt($value)
 * @mixin \Eloquent
 */
class MailSendLog extends Model
{
    use HasDateTimeFormatter;

protected $table = 'mail_send_logs';
    protected $casts = [
        'comments' => MailSendLogCommentCast::class,
        'type' => MailSendLogTypeEnum::class// 限定必须使用此枚举类型
    ];
}

```

## 用法
```php
// 查询数据
use App\Models\MailSendLog;

dump(MailSendLog::first()->comments);// 返回的是 \App\Casts\Manage\MailSendLogComment 对象

dump(MailSendLog::first()->comments->test);// 返回的是 \App\Casts\Manage\MailSendLogComment 对象 test 属性的值

// 新增数据
$M = new MailSendLog();
$M->title = '邮件标题';
$M->content = '<h1>邮件内容</h1>';
$M->comments = new MailSendLogComment('邮件备注'); //必须传入这个类型，否则将会报错
$M->exception = '错误日志';
$M->save();// 保存
```
