當(dāng)代框架基本都是有組件構(gòu)成，這使得框架變得更加靈活。The Laravel Components | github Laravel 中有不少優(yōu)質(zhì)組件，那如何在 Laravel 之外使用 illuminate 組件呢？
illuminate/validation
以 illuminate/validation 為例，validation 有豐富的數(shù)據(jù)驗(yàn)證功能。
在項(xiàng)目的 composer.json 文件中添加：
...
"require": {
...
"illuminate/validation": "^5.8",
...
從 Laravel-Lang/lang 項(xiàng)目中復(fù)制需要的語言文件放到自己的項(xiàng)目中。
例如：在 Yii2 項(xiàng)目中，復(fù)制對應(yīng)語言文件到項(xiàng)目中的 assets/lang/zh-CN/validation.php。
創(chuàng)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;
}
}
在全局函數(shù)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);
}
測試使用：
$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);
}
總結(jié)
