帮朋友新开发的系统做高并发压力测试，所以写了下面这些代码，仅供测试自己的网站，禁止非法使用，否则后果自负！
技术栈：使用了php的Swoole协程扩展，以及swoole的连接池，通过连接池来实现一次性请求的并发次数
php start.php，前提是你的php版本>=7.2，并且安装了swoole扩展（如果你是宝塔环境，可以在php扩展里面自行安装），执行了这段命令，下面的功能就可以正常使用了。kill -9 $(ps -ef|grep test|gawk '$0 !~/grep/ {print $2}' |tr -s '\n' ' ')//修改当前文件资源上限shell_exec("ulimit -n 100960");
$http = new Swoole\Http\Server("0.0.0.0", 9000, SWOOLE_BASE);
$http->on("start", function (\Swoole\Http\Server $server) { swoole_set_process_name("test"); echo "start success!\n";
});
$http->set(['daemonize' => 1]);
$http->on("request", function (\Swoole\Http\Request $request, \Swoole\Http\Response $response) { $response->header("Content-Type", "text/plain"); $url = (string)$request->get['url']; $action = strtolower((string)$request->get['action']); $time = (int)$request->get['time'] + time(); //如果这个小于了当前时间表示过期了 $num = (int)$request->get['num']; $data = urldecode((string)$request->get['data']); if ($action != "get" && $action != "post") { $response->end("action error"); return; } \Swoole\Coroutine::create(function () use ($data, $action, $num, $url, $time) { $connectionPool = new \Swoole\ConnectionPool(function () use ($url, $time) { return new Request($url); }, $num); $connectionPool->fill(); $i = 1; while (true) { if ($time < time()) { $connectionPool->close(); break; } $request = $connectionPool->get(); if ($request instanceof Request) { \Swoole\Coroutine::create(function () use ($data, $action, $connectionPool, $i, $request) { try { if ($action == 'get') { $request->get(); } else if ($action == 'post') { $request->post($data); } $connectionPool->put($request); } catch (Exception $e) { $connectionPool->put($request); } }); } $i++; } }); $message = sprintf('stress tests url:%s - thread:%s - expire:%s', $url, $num, date("Y/m/d H:i:s", $time)); @$response->end((string)$message);
});
$http->start();
