    EventHttp::__construct

    (PECL event >= 1.2.6-beta)

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

    Beschreibung

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

    Constructs the HTTP server object.

    Parameter-Liste

    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.

    Hinweis:

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

    Changelog

    Version Beschreibung
    PECL event 1.9.0 OpenSSL support (ctx) added.

    * Simple HTTP server.
    *
    * To test it:
    * 1) Run it on a port of your choice, e.g.:
    * $ php examples/http.php 8010
    * 2) In another terminal connect to some address on this port
    * and make GET or POST request(others are turned off here), e.g.:
    * $ nc -t 127.0.0.1 8010
    * POST /about HTTP/1.0
    * Content-Type: text/plain
    * Content-Length: 4
    * Connection: close
    * (press Enter)
    *
    * It will output
    * a=12
    * HTTP/1.0 200 OK
    * Content-Type: text/html; charset=ISO-8859-1
    * Connection: close
    *
    * $ nc -t 127.0.0.1 8010
    * GET /dump HTTP/1.0
    * Content-Type: text/plain
    * Content-Encoding: UTF-8
    * Connection: close
    * (press Enter)
    *
    * It will output:
    * HTTP/1.0 200 OK
    * Content-Type: text/html; charset=ISO-8859-1
    * Connection: close
    * (press Enter)
    *
    * $ nc -t 127.0.0.1 8010
    * GET /unknown HTTP/1.0
    * Connection: close
    *
    * It will output:
    * HTTP/1.0 200 OK
    * Content-Type: text/html; charset=ISO-8859-1
    * Connection: close
    *
    * 3) See what the server outputs on the previous terminal window.

    If you try to use the SSL context parameter and you receive an error that you're using 2 parameters instead of 1, then your libevent library is not recent enough to support all features.
    When installing the event extension with PECL, the libevent library needs a certain version to support certain functions.
    PECL does not show any errors or warnings but simple disables everything that your libevent version does not support.

    For further details see my comment at
