Swoole PHP
一个用于 Swoole 的 PHP 代码片段，以空 GIF 响应对 /pixel.gif 的请求，GIF 在启动时只解码一次。
Swoole PHP
<?php
use Swoole\Http\Request;
use Swoole\Http\Response;
use Swoole\Http\Server;
$gif = base64_decode('R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==');
$server = new Server('0.0.0.0', 8080);
$server->set(['http_compression' => false]); // gzip only makes a tiny GIF bigger
$server->on('request', function (Request $request, Response $response) use ($gif) {
if ($request->server['request_uri'] !== '/pixel.gif') {
$response->status(404);
$response->end();
return;
}
$response->header('Content-Type', 'image/gif');
$response->header('Cache-Control', 'no-store');
$response->end($gif);
});
$server->start();
我们运行了此代码片段，并比对了它返回的字节。
