Swoole HTTP static file server example

static.php

<?php
// Simple HTTP static file server using Swoole

$host = $argv[1] ?? '127.0.0.1';
$port = $argv[2] ?? 9501;

$http = new swoole_http_server($host, $port);

// The usage of enable_static_handler seems to produce errors
// $http->set([
//    'document_root' => __DIR__,
//    'enable_static_handler' => true
// ]);

$http->on("start", function ($server) {
    printf("HTTP server started at %s:%s\n", $server->host, $server->port);
    printf("Master  PID: %d\n", $server->master_pid);
    printf("Manager PID: %d\n", $server->manager_pid);
});

$static = [
    'css'  => 'text/css',
    'js'   => 'text/javascript',
    'png'  => 'image/png',
    'gif'  => 'image/gif',
    'jpg'  => 'image/jpg',
    'jpeg' => 'image/jpg',
    'mp4'  => 'video/mp4'

$http->on("request", function ($request, $response) use ($static) {

    if (getStaticFile($request, $response, $static)) {
        return;
    }
    $response->status(404);
    $response->end();
});

$http->start();

function getStaticFile(
    swoole_http_request $request,
    swoole_http_response $response,
    array $static
) : bool {
    $staticFile = __DIR__ . $request->server['request_uri'];
    if (! file_exists($staticFile)) {
        return false;
    }
    $type = pathinfo($staticFile, PATHINFO_EXTENSION);
    if (! isset($static[$type])) {
        return false;
    }
    $response->header('Content-Type', $static[$type]);
    $response->sendfile($staticFile);
    return true;
}

@zx1986 you need to check if $staticFile contains a valid path to your file (line 47).
