全部问题

const [data, setData] = useState(AccordionData)

const AccordionItems = data.map((item) => {

    const OpenClose = (id) => {

        if (id === item.id) {
            setData(data => ([{
                ...data,
                open: true
            }]))

        } else {
            setData(data => ([{
                ...data,
                open: false
            }]))
        }
    }

    return <AccordionItem 
    item={item} 
    key={item.id} 
    OpenClose={OpenClose} 
    id={item.id}
    open={item.open}
    />
})

当我运行该函数时，所有元素都会重置，只有一个元素保留为无文本

<?
  function request($url, $method = 'GET', $fields = null, $cookiesPath = null, $keepCookies = true) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    if (strtoupper($method) === 'GET' && $fields) {
      $url .= '?' . http_build_query($fields);
      curl_setopt($ch, CURLOPT_URL, $url);
    } else if (strtoupper($method) === 'POST') {
      curl_setopt($ch, CURLOPT_POST, true);
      curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
      curl_setopt($ch, CURLOPT_HTTPHEADER, [
        'Content-Type: application/json',
        'Content-Length: ' . strlen(json_encode($fields))
      ]);
    }

    if (!$cookiesPath) {
      $cookiesRandomName = substr(str_shuffle(str_repeat('0123456789abcdefghijklmnopqrstuvwxyz', ceil(30 / 36))), 0, 30);
      $cookiesPath = __DIR__ . $cookiesRandomName . '.txt';
    }

    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiesPath);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiesPath);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);

    $response = curl_exec($ch);

    if ($errorCode = curl_errno($ch)) {
      $errorMessage = curl_error($ch);
        
      curl_close($ch);

      if (file_exists($cookiesPath)) {
        unlink($cookiesPath);
      }

      return [ 'error' => [ 'code' => $errorCode, 'message' => $errorMessage ] ];
    }

    $HTTP_CODE = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    curl_close($ch);

    if ($keepCookies) {
      return [ 'HTTP_CODE' => $HTTP_CODE, 'response' => json_decode($response, true), 'cookiesPath' => $cookiesPath ];
    } else {
      if (file_exists($cookiesPath)) {
        unlink($cookiesPath); // Место ошибки
      }

      return [ 'HTTP_CODE' => $HTTP_CODE, 'response' => json_decode($response, true) ];
    }
  }

我正在编写一个 PHP 脚本，它使用 request() 函数发出 HTTP 请求。在此函数内，我尝试使用 unlink() 删除临时 cookie 文件，但尽管该函数返回成功删除消息，但该文件仍存在于磁盘上。使用示例：

$response = request('https://example.com/login', 'post', [ 'login' => 'name', 'password' => 'hash' ]);
$response = request('https://example.com/profile', 'get', null, $response['cookiesPath'], false);

令人惊讶的是，当 unlink() 在函数外部使用时，不会发生此类事件。一般来说，有趣的行为和最大的陌生感。使用适用于 Windows 11 的 XAMPP。还在 Apache/2.4.6 上的托管上进行了测试。

我将 yandex_maps_mapkit 包添加到项目中，并根据 Yandex 文档（链接）向小部件添加了一个控件。在模拟器中启动时，会显示 YandexMap 控件，甚至右下角可以看到徽标，但地图本身不会加载：

我还在本地启动了Yandex 应用程序的测试示例- 地图在其中正确显示。我没有看到我的项目和这些测试项目之间的设置有任何差异。有一个区别 - 测试用例请求使用地理位置数据的许可，但这会影响地图的加载吗？

android/app/src/main/AndroidManifest.xml中的权限部分在我的和测试项目中是相同的：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Flutter 代码也取自文档 - 在入口点初始化，并在小部件上创建控件：

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
    
  await init.initMapkit(
    apiKey: 'YOUR_API_KEY'
  );
            
  runApp(const MyApp());
}
  
class MyApp extends StatefulWidget {
  const MyApp({super.key});
  
  @override
  State<MyApp> createState() => _MyAppState();
}
  
class _MyAppState extends State<MyApp> {
  
  MapWindow? _mapWindow;
  
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: YandexMap(onMapCreated: (mapWindow) => _mapWindow = mapWindow)
      )
    );
  }
}

我使用包 yandex_maps_mapkit 版本 4.8.2-beta

IDE Android Studio 瓢虫 2024.2.1

我在注册新帐户时正在写用户电子邮件的确认信息

一切都按照以下原则进行：我们接收用户的电子邮件，创建一个 10000 - 99999 之间的随机数，使用此代码创建 cookie 并通过电子邮件将代码发送给他

$user_email = trim(filter_var($_POST['email'], FILTER_SANITIZE_EMAIL));
$code = trim(rand(10000, 99999));
setcookie("code", $code, time() + 60 * 5, "/lib/check_mail.php");
mail($user_email, 'Код подтверждения адреса Эл.Почты', $code);
header('Location: /lib/check_mail.php');

在下一个窗口中，我们将用户输入的代码与通过电子邮件发送的代码进行比较

$code = $_POST['code'];
$user_code = $_COOKIE['code'];

if ($code == $user_code){
 // Код введен верно
} else {
 // Код введен НЕ верно
}

问题：此代码的安全性和最新程度如何？如何使检查用户的电子邮件更加相关和安全？

我为我公司的 Java 后端职位空缺编写了一个测试，以下是包含任务的文档文本：

User ManagProject 标题：图书馆管理系统 该项目旨在创建一个图书馆管理系统，这是一个帮助图书馆工作人员以简单有效的方式管理图书、顾客（图书馆用户）和图书借阅的软件工具。

Book Management:
    Add new books with details like title, author, ISBN, and genre.
    Edit and update book info.
    Remove books from the library.
    Display a list of all library books.

Patron Management:
    Add new patrons with their names, contact info, and membership status.
    Edit and update patron details.
    Remove patrons from the library.
    Show a list of all library patrons.

Borrowing System:
    Enable library patrons to borrow books.
    Track due dates for borrowed books.
    Allow librarians to mark books as returned.
    Notify patrons if they have overdue books.

Search and Filtering:

    Add options to sort and filter lists of books and patrons.

Reporting:
    Generate reports that display overdue books and transaction history.
    Provide statistics about the library's book collection and patron activity.   Technical Details:

User Interface:
    Design an easy-to-use web-based interface for librarians.
    Ensure it works well on different screen sizes.

Security:
    Set up user login and access control for librarians.
    Safeguard sensitive information, like passwords and patron data.

Database:
    Use a relational database (e.g., MySQL, PostgreSQL) to store book, patron, and transaction data.
    Create a suitable database structure and relationships.

Performance:
    Optimize how the system fetches data from the database.
    Ensure the system can handle multiple users at once.

Scalability:
    Design the system to grow smoothly as the library's needs expand.   Technology Stack:

Backend: Java (with Spring Boot)
Frontend: HTML, CSS, JavaScript
Database: Relational (e.g., MySQL, PostgreSQL)
Security: Spring Security
Database Access: Hibernate
User Interface Templating: Thymeleaf or similar   Project Deliverables:

The project's source code.
Documentation (README) explaining how to set up and run the application.
Brief documentation describing the project's structure and design choices.
Source code should be provided as a git repository.   Evaluation Criteria:   The project will be assessed based on:

Functionality: Does the system meet all functional requirements?
User Interface: Is the interface user-friendly and adaptable to different devices?
Code Quality: Is the code well-organized, readable, and maintainable?
Security: Is user authentication and data protection implemented correctly?
Database Design: Does the database structure fit the project's needs?
Documentation: Is there clear documentation for setting up and using the application?
Error Handling: Does the application handle errors gracefully?
Performance: How efficiently does the application perform its tasks?

通过测试后，他们说很明显“是我自己写的”（确实如此）并告诉我改正然后再试，但不幸的是他们没有告诉我任务到底出了什么问题。我自己找不到具体需要纠正的地方，如果您能告诉我，我会很高兴这是Github上该项目的链接。
