备注： 常用到的功能记录一下，方便使用

<?php

use Swoole\Http\Request;
use Swoole\Http\Response;
use Swoole\Coroutine\Http\Server;
use function Swoole\Coroutine\run;

run(function () {
    $server = new Server('0.0.0.0', 9502, false);
    $server->handle('/', function (Request $request, Response $response) {

        $response->header('Content-Type', 'application/json; charset=utf-8');

        $response->header('access-control-allow-credentials', 'true');
        $response->header('access-control-allow-methods', 'GET,HEAD,POST,OPTIONS');
        $response->header('access-control-allow-headers', 'content-type,Authorization');
        $response->header('Access-Control-Allow-Private-Network', 'true');
        $origin = empty($request->header['origin']) ? '*' : $request->header['origin'];
        $response->header('access-control-allow-origin', $origin);
        $request_method = empty($request->header['request_method']) ? '' : $request->header['request_method'];
        if ($request_method == "OPTIONS") {
            $response->status(200);
            $response->end();
            return null;
        }

        $result = [];
        try {
            $result = [
                'code' => 200,
                "msg" => 'success',
                "data" => []
            ];
        } catch (\RuntimeException $e) {
            $result = ["code" => 500, 'msg' => 'system error' . $e->getMessage()];
        }

        $response->end(json_encode($result, JSON_UNESCAPED_UNICODE));
    });

    $server->start();
});
