Event EventHttp::__construct

(PECL event >= 1.2.6-beta)

EventHttp::__construct — EventHttp 객체(HTTP 서버) 생성

설명

---

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

HTTP 서버 개체를 생성합니다.

매개변수

---

base

관련 이벤트 베이스.

ctx

EventSslContext 클래스 개체입니다. 일반 HTTP 서버를 HTTPS 서버로 바꿉니다. 이는 ctx가 올바르게 구성된 경우 기본 버퍼 이벤트가 OpenSSL 소켓을 기반으로 한다는 것을 의미합니다. 따라서 모든 트래픽은 SSL 또는 TLS를 통과합니다.

메모: 이 매개변수는 Event가 OpenSSL 지원으로 컴파일되고 Libevent 2.1.0-alpha 이상에서만 사용 가능한 경우에만 사용할 수 있습니다.

반환 값

예제 #1 Simple HTTP server

                  
<?php
/*
 * 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.
