Laravel VueJS地址验证RegExp不工作

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Validator;

class AddressValidationServiceProvider extends ServiceProvider
{
    public function boot()
    {
        Validator::extend('address', function ($attribute, $value, $parameters, $validator) {
            // 正则表达式用于验证地址的格式
            $pattern = '/^[A-Za-z0-9\s\-\,\#]+$/';

            return preg_match($pattern, $value);
        });

        Validator::replacer('address', function ($message, $attribute, $rule, $parameters) {
            return str_replace(':attribute', $attribute, 'The :attribute format is invalid.');
        });
    }
}

'providers' => [
    // 其他的ServiceProvider
    App\Providers\AddressValidationServiceProvider::class,
],

$rules = [
    'address' => 'required|address',
];

$validator = Validator::make($request->all(), $rules);

if ($validator->fails()) {
    // 验证失败的处理逻辑
}
