Oder gehen Sie direkt zum Code:
<?php$http = new swoole_http_server("0.0.0.0", 9501);$http->on('request', function($request, $response){ $swoole_mysql1 = new Swoole\Coroutine\MySQL(); $swoole_mysql2 = new Swoole\Coroutine\MySQL(); $swoole_mysql1->connect([ 'host' => '127.0.0.1', 'port' => 3306, 'user' => 'root', 'password' => 'root', 'database' => 'swoole', ]); $swoole_mysql2->connect([ 'host' => '127.0.0.1', 'port' => 3306, 'user' => 'root', 'password' => 'root', 'database' => 'swoole', ]); $res1 = $swoole_mysql1->query('SELECT * FROM data1'); $res2 = $swoole_mysql2->query('SELECT * FROM data2'); $response->header("Content-Type", "text/html; charset=utf-8"); $response->end("<h1>Hello Swoole. #".count($res1).count($res2)."</h1>"); });$http->start();
Empfohlen (kostenlos): swoole
Verwenden Sie einen Browser, um darauf zuzugreifen. http://ip:9501
Asynchrones MySQL muss nicht auf den Abschluss der ersten Abfrage warten, bevor die zweite Abfrage ausgeführt wird. Der Effekt ist deutlicher, wenn auf verschiedene Server, verschiedene Datenbanken und verschiedene Tabellen zugegriffen wird.
Vergleichen Sie den synchronen MySQL-Abfragecode:
<?php$http = new swoole_http_server("0.0.0.0", 9501);$http->on('request', function($request, $response){ $swoole_mysql1 = mysqli_connect('127.0.0.1', 'root', 'root', 'swoole', 3306); $swoole_mysql2 = mysqli_connect('127.0.0.1', 'root', 'root', 'swoole', 3306); $res1 = $swoole_mysql1->query('SELECT * FROM data1'); $res2 = $swoole_mysql2->query('SELECT * FROM data2'); $response->header("Content-Type", "text/html; charset=utf-8"); $response->end("<h1>Hello Swoole. #".$res1->num_rows.$res2->num_rows."</h1>"); });$http->start();
Der synchrone Code verwendet die native PHP-Methode zum Abfragen von Daten.
Lassen Sie uns zwei Abfragemethoden mit ab einem Leistungstest unterziehen:
ab -c 100 -n 1000 http://127.0.0.1:9501/
