  • 当代框架基本都是有组件构成,这使得框架变得更加灵活。The Laravel Components | github Laravel 中有不少优质组件,那如何在 Laravel 之外使用 illuminate 组件呢?

    illuminate/validation

    illuminate/validation 为例,validation 有丰富的数据验证功能。

    在项目的 composer.json 文件中添加:

    ...
     "require": {
      ...
      "illuminate/validation": "^5.8",
    ...
    
    
    

    Laravel-Lang/lang 项目中复制需要的语言文件放到自己的项目中。

    例如:在 Yii2 项目中,复制对应语言文件到项目中的 assets/lang/zh-CN/validation.php。

    创建 common/Validator.php:

    namespace app\common;
    
    use Illuminate\Filesystem\Filesystem;
    use Illuminate\Translation\FileLoader;
    use Illuminate\Translation\Translator;
    use Illuminate\Validation\Factory;
    
    class Validator
    {
     private static $instance = null;
    
     private function __construct()
     {
     }
    
     public static function getInstance(): Factory
     {
     if (null === static::$instance) {
      $translationPath = get_alias('@assets/lang');
      $translationLocale = 'zh-CN';
      $transFileLoader = new FileLoader(new Filesystem(), $translationPath);
      $translator = new Translator($transFileLoader, $translationLocale);
      static::$instance = new Factory($translator);
     }
    
     return static::$instance;
     }
    }
    
    

    在全局函数文件添加:

    // https://learnku.com/docs/laravel/5.8/validation/3899#manually-creating-validators
    // $rules = [
    // 'name' => 'required|string|min:2|max:5',
    // 'code' => 'required|string|min:2|max:5',
    // ];
    function validator(array $data, array $rules, array $messages = [], array $customAttributes = [])
    {
     return \app\common\Validator::getInstance()->make($data, $rules, $messages, $customAttributes);
    }
    

    测试使用:

    $rules = ['name' => 'required|numeric'];
    $customAttributes = ['name' => 'My name'];
    $messages = ['name.required' => 'A name is required',];
    
    $validator = validator($data, $rules, $customAttributes, $messages);
    if ($validator->fails()) {
     $errors = $validator->errors()->all();
     Response::error(Errors::ParamsInvalid, implode(',', $errors), $errors);
    }
    

    总结
