EventHttp::accept — Makes an HTTP server accept connections on the specified socket stream or resource

Beschreibung

public EventHttp::accept( mixed $socket ): bool

Makes an HTTP server accept connections on the specified socket stream or resource. The socket should be ready to accept connections.

Can be called multiple times to accept connections on different sockets.

Hinweis:
To bind a socket, listen , and accept connections on the socket in s single call use EventHttp::bind() . EventHttp::accept() is needed only if one already has a socket ready to accept connections.

Parameter-Liste

socket: Socket resource, stream or numeric file descriptor representing a socket ready to accept connections.

Rückgabewerte

Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.

Beispiele

Beispiel #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.
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

Client:
$ nc 127.0.0.1 8091
GET /about HTTP/1.0
Connection: close

HTTP/1.0 200 OK
Content-Type: text/html; charset=ISO-8859-1
Connection: close

Server:
127.0.0.1 8091
127.0.0.2 8092
URI: /about
OK
