我尝试在laravel中验证日期，只有在选中"One_way“复选框的情况下。但即使选择了它，它也会显示错误消息

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;

public function validateDate(Request $request)
{
    $validator = Validator::make($request->all(), [
        'One_way' => 'required|in:1',
        'date' => 'required_if:One_way,1|date',
    ]);

    if ($validator->fails()) {
        // 验证失败，显示错误消息
        return redirect()->back()->withErrors($validator)->withInput();
    }

    // 验证通过，继续处理其他逻辑
    // ...

    return redirect()->back()->withSuccess('验证通过！');
}
