如何在CakePHP 4中扩展JSON视图以返回始终相同的模式

// src/View/CustomJsonView.php

namespace App\View;

use Cake\View\JsonView;

class CustomJsonView extends JsonView
{
    /**
     * 序列化数据为JSON格式
     *
     * @param mixed $serialize 序列化的数据
     * @return string JSON格式的数据
     */
    protected function _serialize($serialize)
    {
        $options = $this->getJsonOptions();
        $options |= JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES;
        return json_encode($serialize, $options);
    }
}

// src/Controller/ExampleController.php

namespace App\Controller;

use App\View\CustomJsonView;

class ExampleController extends AppController
{
    public function index()
    {
        // 设置视图类为自定义的JSON视图类
        $this->viewBuilder()->setClassName(CustomJsonView::class);

        // 其他逻辑处理...

        // 设置要返回的数据
        $data = [
            'message' => 'Hello, World!',
            'timestamp' => time()
        ];
        $this->set(compact('data'));
        $this->viewBuilder()->setOption('serialize', 'data');
    }
}

// config/routes.php

use Cake\Routing\RouteBuilder;
use Cake\Routing\Router;

Router::scope('/', function (RouteBuilder $routes) {
    // 其他路由配置...

    // 配置JSON视图路由
    $routes->setExtensions(['json']);
});
