如何在laravel中生成错误消息

public function store(Request $request)
{
    $rules = [
        'name' => 'required',
        'email' => 'required|email',
        'password' => 'required|min:6',
    ];

    $messages = [
        'name.required' => '请输入姓名',
        'email.required' => '请输入邮箱',
        'email.email' => '请输入有效的邮箱地址',
        'password.required' => '请输入密码',
        'password.min' => '密码长度不能少于6个字符',
    ];

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

    if ($validator->fails()) {
        return redirect('register')
                    ->withErrors($validator)
                    ->withInput();
    }

    // 如果验证通过，继续处理其他逻辑

    // ...
}
