Laravel中的自定义验证消息

Question

我在laravel中遇到自定义验证消息的问题。 我要验证用户创建请求，我的数据如下：

  

first_name:Akhsay middle_name:R last_name:Doe gender:male miscellaneous:{"dob":"","birth_name":"xyz"}

我已经创建了用于在userCreateRequest.php中创建用户的验证规则

public function rules()
{
    return [
        'first_name' => 'required',
        'middle_name' => 'required',
        'last_name' => 'required',
        'gender' => 'required',
        'miscellaneous' => 'json|validate_misc_info',
    ];
}

/**
 * validation messages
 *
 * @return array
 */
public function messages()
{
    return [
        "first_name.required" => "First name is required.",
        "middle_name.required" => "Middle name is required.",
        "last_name.required" => "Last name is required.",
        "gender.required" => "Gender is required.",
        'miscellaneous.validate_misc_info' => '(**want to show specific error message here**)?'
    ];
}

对于其他信息，我创建了一个自定义验证服务提供程序，并且在自定义验证器的启动方法中，我将验证代码编写为

 Validator::extend('validate_misc_info',function($attribute, $value, $params, $validator) {

        $data = json_decode($value, true);
        $rules = [
            "dob" => "required|date",
            "birth_name" => "required|min:2|max:50",
        ];
        $messages= [
            "dob.required" => "Date of birth is required",
            "birth_name.required" => "Birth name is required",
        ];

        $validator = $data ? Validator::make($data, $rules, $messages) : false;

        if ($validator && $validator->fails()) {

            return false;
        }

        return true;
    });

但是当我在userCreateRequest.php中使用此验证规则时

public function rules()
{
    return [
        'first_name' => 'required',
        'middle_name' => 'required',
        'last_name' => 'required',
        'initial' => 'required',
        **'miscellaneous' => 'json|validate_misc_info',**
    ];
}

它向我显示错误

{
"message": "The given data was invalid.",
"errors": {
    "miscellaneous": [
        "validation.validate_misc_info"
    ]
}

但我想显示特定的错误消息为

{
"message": "The given data was invalid.",
"errors": {
    "miscellaneous": [
        "Date of birth is required"
    ]
}

请帮助我。
