## 引入组件包
~~~
composer require hyperf/validation
composer require hyperf/translation
~~~
## 自动验证方式
### 发布配置文件
~~~
// 发布 Translation 组件的文件
php bin/hyperf.php vendor:publish hyperf/translation
// 发布验证器组件的文件
php bin/hyperf.php vendor:publish hyperf/validation
~~~
### 添加中间件
> 在`config\autoload\middlewares.php`文件中添加验证中间件
~~~
return [
'http' => [
\Hyperf\Validation\Middleware\ValidationMiddleware::class
],
];
~~~
### 添加异常处理器
~~~
return [
'handler' => [
'http' => [
\Hyperf\Validation\ValidationExceptionHandler::class,
],
],
];
~~~
### 生成验证类
> 命令生成
~~~
php bin/hyperf.php gen:request FooRequest
~~~
> 生成类如下
~~~
declare(strict_types=1);
namespace App\Request;
use Hyperf\Validation\Request\FormRequest;
class FooRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*/
public function authorize(): bool
{
return true;
}
/**
* Get the validation rules that apply to the request.
*/
public function rules(): array
{
return [
'foo' => 'required|max:255',
'bar' => 'required',
];
}
public function messages(): array
{
return [
'foo.required' => 'foo is required',
'bar.required' => 'bar is required',
];
}
}
~~~
### Controller 中使用
> 如果验证不通过，则会被ValidationExceptionHandler拦截，返回错误的信息，如果想返回json信息，请自定修改这个异常类
~~~
public function test(FooRequest $request){
$validated = $request->validated();
var_dump($validated);
}
~~~
## 手动验证方式
### Controller 中使用
~~~
public function test(RequestInterface $request)
{
$validator = $this->validationFactory->make(
$request->all(),
[
'foo' => 'required',
'bar' => 'required',
],
[
'foo.required' => 'foo is required',
'bar.required' => 'bar is required',
]
);
var_dump($validator->fails());
if ($validator->fails()){
// Handle exception
$errorMessage = $validator->errors()->first();
var_dump($errorMessage);
}
}
~~~
