範例
示例 #1 EventHttp::accept() example
<?php
$base = new EventBase();
$http = new EventHttp($base);
$addresses = array (
8091 => "127.0.0.1",
8092 => "127.0.0.2",
);
$i = 0;
$socket = array();
foreach ($addresses as $port => $ip) {
echo $ip, " ", $port, PHP_EOL;
$socket[$i] = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if (!socket_bind($socket[$i], $ip, $port)) {
exit("socket_bind failed\n");
}
socket_listen($socket[$i], 0);
socket_set_nonblock($socket[$i]);
if (!$http->accept($socket[$i])) {
echo "Accept failed\n";
exit(1);
}
++$i;
}
$http->setCallback("/some-page", function() {
echo "(some-page)\n";
echo "URI: ", $req->getUri(), PHP_EOL;
$req->sendReply(200, "OK");
echo "OK\n";
});
$http->setDefaultCallback(function($req) {
echo "URI: ", $req->getUri(), PHP_EOL;
$req->sendReply(200, "OK");
echo "OK\n";
});
$signal = Event::signal($base, SIGINT, function () use ($base) {
echo "Caught SIGINT. Stopping...\n";
$base->stop();
});
$signal->add();
$base->dispatch();
echo "END\n";
// We didn't close sockets, since Libevent already sets
// CLOSE_ON_FREE and CLOSE_ON_EXEC flags on the file
// descriptor associated with the sockets.
?>
