PHP와 Vue.js를 사용하여 보안 API 인터페이스를 개발하는 방법

// index.php

<?php
// 引入路由类
require_once 'Router.php';

// 定义路由表
$router = new Router();
$router->addRoute('/api/users', 'UserController@index');
$router->addRoute('/api/user/{id}', 'UserController@show');
// ...

// 解析URL
$url = $_SERVER['REQUEST_URI'];
$route = $router->matchRoute($url);

// 检查访问权限
if ($route && checkAccess($_SESSION['user'], $route->getPath())) {
  // 执行相应的处理逻辑
  $controller = new $route->getController();
  $action = $route->getAction();
  $controller->$action();
} else {
  // 返回未授权错误
  header('HTTP/1.1 401 Unauthorized');
  echo json_encode(['error' => 'Unauthorized']);
}

// 检查访问权限
function checkAccess($user, $path) {
  // TODO: 根据用户角色和资源权限判断是否有权限访问
  return true;
}
?>

// UserController.php

<?php
class UserController {
  public function index() {
    // 输入验证
    $params = filter_input_array(INPUT_GET, [
      'pageIndex' => FILTER_VALIDATE_INT,
      'pageSize' => FILTER_VALIDATE_INT,
    ]);

    // 处理逻辑
    $pageIndex = $params['pageIndex'];
    $pageSize = $params['pageSize'];
    $users = User::findAll($pageIndex, $pageSize);

    // 返回结果
    header('Content-Type: application/json');
    echo json_encode($users);
  }

  // ...
}
?>

// AuthController.php

<?php
class AuthController {
  public function login() {
    // 输入验证
    $params = filter_input_array(INPUT_POST, [
      'username' => FILTER_SANITIZE_STRING,
      'password' => FILTER_SANITIZE_STRING,
    ]);

    // 验证用户名密码
    if (validateUser($params['username'], $params['password'])) {
      // 生成Token并存储到Session中
      $token = generateToken();
      $_SESSION['token'] = $token;

      // 返回Token
      header('Content-Type: application/json');
      echo json_encode(['token' => $token]);
    } else {
      // 返回登录失败错误
      header('HTTP/1.1 401 Unauthorized');
