EventHttp::__construct
EventHttp::__construct
(PECL event >= 1.2.6-beta)
EventHttp :: __ construct - 构造EventHttp对象(HTTP服务器)
描述
public EventHttp::__construct ( EventBase $base [, EventSslContext $ctx = NULL ] )
构造HTTP服务器对象。
参数
base
相关的事件库。
ctx
EventSslContext类对象。将纯HTTP服务器转换为HTTPS服务器。这意味着如果ctx
配置正确,则基础缓冲区事件将基于OpenSSL套接字。因此,所有流量都将通过SSL或TLS。
注意
:只有在使用OpenSSL支持编译Event
并且仅使用Libevent 2.1.0-alpha
及更高版本时,此参数才可用。
返回值
返回EventHttp对象。
更新日志
版本 | 描述 |
---|---|
1.9.0 | 增加了OpenSSL支持(ctx)。 |
例
示例#1简单的HTTP服务器
<?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.

上面的例子会输出:
