在 Laravel 之外使用 illuminate 组件

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);
}
