使用validation验证器

仓库地址: validation

安装

composer require illuminate/validation

我们先单例validation验证器

namespace App\Vendor\Validators;
use Illuminate\Validation\Factory;
class Validator extends Factory
{
    public static function getInstance()
    {
        static $validator = null;
        if ($validator === null) {
            $test_translation_path = __DIR__.'/lang';
            $test_translation_locale = 'en';
            $translation_file_loader = new \Illuminate\Translation\FileLoader(new \Illuminate\Filesystem\Filesystem, $test_translation_path);
            $translator = new \Illuminate\Translation\Translator($translation_file_loader, $test_translation_locale);
            $validator = new \Illuminate\Validation\Factory($translator);
        }
        return $validator;
    }
}

然后可以在控制器中使用
```
use App\Vendor\Validators\Validator;

// 在Index控制器类添加以下方法
function index(){
//验证数据
$data = [
‘title’ => ‘123457’,
‘status’ => 1
];
//验证规则
$rules = [
‘title’ => ‘required|string|min:2|max:5’,
‘status’ =>’required|integer’
];
//错误消息
$messages = [
];
//属性名称
$attributes = [
‘title’ => ‘名称’,
‘status’ => ‘状态’,
];
$validator = Validator::getInstance()->make($data, $rules, $messages, $attributes);
if ($validator->fails()) {
$this->response()->write($validator->messages()->first());
//$this->response()->write($validator->errors());
$this->response()->end();
}
$this->response()->write(‘ok’);
}
