自定义json数组验证规则

1.php artisan make:rule  名称

2.规则文件内容如下：

<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;
use Illuminate\Support\Facades\Validator;

class JsonArray implements Rule
{
    protected $rules;
    protected $errorMessage;
    /**
     * Create a new rule instance.
     *
     * @return void
     */
    public function __construct($rules)
    {
        $this->rules = $rules;
    }

    /**
     * @param string $attribute
     * @param mixed $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        $list = json_decode($value,true);
        if(empty($list)){
            $this->errorMessage =  'json数据格式错误';
            return false;
        }
        foreach($list as $item){
            $validator = Validator::make($item,$this->rules);
            if($validator->fails()){
                $this->errorMessage =  $validator->errors()->first();
                return false;
            }
        }
        return true;
    }

    /**
     * @return array|string
     */
    public function message()
    {
        return 'json详情数据验证失败-'.$this->errorMessage;
    }
}

具体用法：

public function rules()
    {
        return [
     
            'goods_detail' => [
                'required',
                'json',
                new JsonArray([
                'goods_sku_id' => 'required|integer|min:1',
                'count'        => 'required|integer|min:1',
            ])],
        ];
    }
