在Laravel上验证2深度数组

php artisan make:validator ArrayValidator

public function rules()
{
    return [
        'array_field' => 'required|array',
        'array_field.*' => 'array',
        'array_field.*.*' => 'required|string',
    ];
}

public function messages()
{
    return [
        'array_field.required' => 'The array field is required.',
        'array_field.array' => 'The array field must be an array.',
        'array_field.*.array' => 'The elements of array field must be arrays.',
        'array_field.*.*.required' => 'The elements of array field must not be empty.',
        'array_field.*.*.string' => 'The elements of array field must be strings.',
    ];
}

use App\Validators\ArrayValidator;

public function validateArray(Request $request, ArrayValidator $validator)
{
    $validatedData = $validator->validate($request->all());

    // 验证通过，继续处理逻辑
}
