EventHttp::__construct

    (PECL event >= 1.2.6-beta)

    EventHttp::__construct — Constructs EventHttp object (the HTTP server)

    Descripción

    publicEventHttp::__construct(EventBase$base, EventSslContext$ctx = null)

    Constructs the HTTP server object.

    Parámetros

    base

    Associated event base.

    ctx

    EventSslContext class object. Turns plain HTTP server into HTTPS server. It means that if ctx is configured correctly, then the underlying buffer events will be based on OpenSSL sockets. Thus, all traffic will pass through the SSL or TLS.

    Nota:

    This parameter is available only if Event is compiled with OpenSSL support and only with Libevent 2.1.0-alpha and higher.

    Historial de cambios

    VersiónDescripción
    PECL event 1.9.0 OpenSSL support (ctx) added.

    Ejemplo #1 Simple HTTP server

    <?php


    function _http_dump($req, $data) {
    static     $counter = 0;
    static     $max_requests = 2;

    if (++    $counter >= $max_requests) {
    echo     "Counter reached max requests $max_requests. Exiting\n";
    exit();
    }

    echo     __METHOD__, " called\n";
    echo     "request:"; var_dump($req);
    echo     "data:"; var_dump($data);

    echo     "\n===== DUMP =====\n";
    echo     "Command:", $req->getCommand(), PHP_EOL;
    echo     "URI:", $req->getUri(), PHP_EOL;
    echo     "Input headers:"; var_dump($req->getInputHeaders());
    echo     "Output headers:"; var_dump($req->getOutputHeaders());

    echo     "\n >> Sending reply ...";
    $req->sendReply(200, "OK");
    echo     "OK\n";

    echo     "\n >> Reading input buffer ...\n";
    $buf = $req->getInputBuffer();
    while (    $s = $buf->readLine(EventBuffer::EOL_ANY)) {
    echo     $s, PHP_EOL;
    }
    echo     "No more data in the buffer\n";
    }

    function     _http_about($req) {
    echo     __METHOD__, PHP_EOL;
    echo     "URI: ", $req->getUri(), PHP_EOL;
    echo     "\n >> Sending reply ...";
    $req->sendReply(200, "OK");
    echo     "OK\n";
    }

    function     _http_default($req, $data) {
    echo     __METHOD__, PHP_EOL;
    echo     "URI: ", $req->getUri(), PHP_EOL;
    echo     "\n >> Sending reply ...";
    $req->sendReply(200, "OK");
    echo     "OK\n";
    }

    $port = 8010;
    if (    $argc > 1) {
    $port = (int) $argv[1];
    }
    if (    $port <= 0 || $port > 65535) {
    exit(    "Invalid port");
    }

    $base = new EventBase();
    $http = new EventHttp($base);
    $http->setAllowedMethods(EventHttpRequest::CMD_GET | EventHttpRequest::CMD_POST);

    $http->setCallback("/dump", "_http_dump", array(4, 8));
    $http->setCallback("/about", "_http_about");
    $http->setDefaultCallback("_http_default", "custom data value");

    $http->bind("0.0.0.0", 8010);
    $base->loop();
    ?>

    El resultado del ejemplo sería algo similar a:

    a=12 HTTP/1.0 200 OK Content-Type: text/html; charset=ISO-8859-1 Connection: close HTTP/1.0 200 OK Content-Type: text/html; charset=ISO-8859-1 Connection: close (press Enter) HTTP/1.0 200 OK Content-Type: text/html; charset=ISO-8859-1 Connection: close
