1.在/web/tool/demo/server下新建http_server.php
```
<?php
$http = new swoole_http_server("0.0.0.0", 9503);
$http->on('request', function($request, $response) {
$response->cookie("singwa", "xsssss", time() + 1800);
//$response->end("<h1>hello world!</h1>");
$response->end("sss". json_encode($request->get));
});
$http->start();
```
2.可以在终端用命令验证
```
curl http://127.0.0.1:9503
```
3.或者浏览器输入验证
