例如，我知道如何使用普通 php 创建缓存页面，

// @ref: http://wesbos.com/simple-php-page-caching-technique/
//
// define the path and name of cached file
$cachefile = 'cache/'.date('M-d-Y').'.php';

// define how long we want to keep the file in seconds. I set mine to 1 hour.
$cachetime = 3600;

// Check if the cached file is still fresh. If it is, serve it up and exit.
if (file_exists($cachefile) && time() - $cachetime < filemtime($cachefile)) {
    include($cachefile);
    echo '<!-- cached page - '.date('l jS \of F Y h:i:s A', filemtime($cachefile)) . ' -->';
    exit;
}

// if there is either no file OR the file to too old, render the page and capture the HTML.
ob_start();
?>
    <html>
        output all your html here.
    </html>
<?php

// We're done! Save the cached content to a file
$fp = fopen($cachefile, 'w');
fwrite($fp, ob_get_contents());
fclose($fp);

// finally send browser output
ob_end_flush();

但是如何在 Slim 3 或其他微框架中做到这一点？

use Slim\Http\Request;
use Slim\Http\Response;

require_once __DIR__ . '/../vendor/autoload.php';

$app = new \Slim\App();

// Routes:
$app->get('/', function (Request $request, Response $response, array $args) {
    $response->getBody()->write('Hello, World!');

    return $response;
});

$app->run();

有任何想法吗？

我使用的是相同的 Slim-3 框架，但我使用缓存作为中间件：

<?php
    $app->add(
        new \App\Middleware\HttpCache\Cache($container)
    );

在该类中，您可以添加方法：

<?php

    namespace App\Middleware\HttpCache;
    use App\Middleware\Middleware;

    class Cache extends Middleware {
        *// your methods go here*
    }

您可以像在普通 php 中创建的方式一样创建缓存文件。对于 slim3，无需额外的努力。
