在 Laravel 9 中，验证索引数组的实现

图3

1、现在的请求参数结构如下所示。准备验证 config[‘appoint_country’][‘appoint_country’][‘value’][0]、config[‘appoint_country’][‘appoint_country’][‘value’][1]。如图1

图1

{
    "title": "自动交运",
    "level": 1,
    "logistics_channel_id": 474241,
    "auto_shipment": 1,
    "description": null,
    "is_publish": 1,
    "config": {
        "appoint_country": {
            "invert_select": 0,
            "value": [
                "AD",
                "AE"
            ]
        },
        "reship_order": {
            "value": 0
        }
    }
}

2、验证代码实现如下，尝试验证索引数组中的值的最大长度为 1。验证失败，符合预期。如图2

图2

        $validator = Validator::make(
            $request->all(),
            [
                'config.appoint_country'               => 'array',
                'config.appoint_country.invert_select' => 'required_with:config.appoint_country|in:0,1',
                'config.appoint_country.value'         => 'required_with:config.appoint_country|array',
                'config.appoint_country.value.*'       => 'required_with:config.appoint_country.value.*|max:1',
            ],
            [
                'config.appoint_country.array'                       => '订单目的地为指定国家参数类型错误',
                'config.appoint_country.invert_select.required_with' => '是否反选参数为必填',
                'config.appoint_country.invert_select.in'            => '是否反选参数类型错误',
                'config.appoint_country.value.required_with'         => '请选择国家',
                'config.appoint_country.value.array'                 => '国家参数类型错误',
            ]
        );

3、为给定属性指定自定义消息。调整如下

        $validator = Validator::make(
            $request->all(),
            [
                'config.appoint_country'               => 'array',
                'config.appoint_country.invert_select' => 'required_with:config.appoint_country|in:0,1',
                'config.appoint_country.value'         => 'required_with:config.appoint_country|array',
                'config.appoint_country.value.*'       => 'required_with:config.appoint_country.value.*|max:1',
            ],
            [
                'config.appoint_country.array'                       => '订单目的地为指定国家参数类型错误',
                'config.appoint_country.invert_select.required_with' => '是否反选参数为必填',
                'config.appoint_country.invert_select.in'            => '是否反选参数类型错误',
                'config.appoint_country.value.required_with'         => '请选择国家',
                'config.appoint_country.value.array'                 => '国家参数类型错误',
    'config.appoint_country.value.*.max'                 => '国家参数类型最大长度是1',
            ]
        );

4、验证失败后，响应自定义的消息。如图3
