从laravel转到webman发现表单验证不能使用依赖注入自动验证所以改造了一下。

实现思路

1、创建一个BaseValidate基类，基类继承app\validate，校验类继承基类
2、在基类的构造方法里调用check方法，这样在依赖注入的时候就会自动进行校验，校验失败抛出异常
3、在异常处理类中接住，并自定义响应

BaseValidate基类代码

<?php
declare (strict_types=1);

namespace app\validate;

use think\Validate;

class BaseValidate extends Validate
{

    public function __construct() {
        if ($this->scene){
            $scene = request()->action;
            if (!$this->hasScene($scene)){
                return;
            }
            $this->scene($scene);
        }
        $this->failException()->check(request()->all());
    }

}

校验类代码

<?php
declare (strict_types=1);

namespace app\validate;

use app\validate\BaseValidate;

class TestValidate extends BaseValidate
{

    protected $rule = [
        'name' => 'require',
        'age'  => 'require',
    ];

    protected $message = [
        'name.require' => '名称必须',
        'age.require'  => '年龄必须',
    ];

    protected $scene = [
        'edit' => ['name'],
        'del' => ['age'],
    ];

}

namespace support\exception;

use think\exception\ValidateException;
use Throwable;
use Webman\Exception\ExceptionHandler;
use Webman\Http\Request;
use Webman\Http\Response;

/**
 * Class Handler
 * @package support\exception
 */
class Handler extends ExceptionHandler
{
    public $dontReport = [
        BusinessException::class,
    ];

    public function report(Throwable $exception)
    {
        parent::report($exception);
    }

    public function render(Request $request, Throwable $exception): Response
    {
        if ($exception instanceof ValidateException) {
            return json([
                'code' => 500,
                'msg' => $exception->getMessage(),
                'data' => null
            ]);
        }
        if(($exception instanceof BusinessException) && ($response = $exception->render($request)))
        {
            return $response;
        }

        return parent::render($request, $exception);
    }

}

控制器调用(1)

<?php

namespace app\controller;

use app\validate\TestValidate;

class IndexController
{

    public function edit(TestValidate $validate)
    {
        return 'edit';
    }

    public function del(TestValidate $validate)
    {
        return 'del';
    }

}

控制器调用(2)

<?php

namespace app\controller;

use app\validate\TestValidate;

class IndexController
{

    public function __construct()
    {
        new TestValidate();
    }

    public function index()
    {
        return 'index';
    }

    public function edit()
    {
        return 'edit';
    }

    public function del()
    {
        return 'del';
    }

}
