PHP怎样处理HTTPS请求

Jun 06, 2016 pm 08:38 PM
https php

请问如何用PHP处理HTTPS的请求?
我想问的不是用curl发送请求,也不是问https的原理,我就是想了解浏览器发送HTTPS请求后PHP需要做哪些配置或者写哪些代码来处理这个请求,诸位可否有示例代码?
网上搜过了,不是curl发送https请求的例子,就是HTTPS原理的例子,但是原理我懂了可是不知道开始...
谢谢

phphttps没有半毛钱关系,因为php是一种语言/脚本解释器,不是一种服务器

一个请求到达服务器,无论是http还是https,先经过web server,如apachenginx,由web server处理与客户端之间基于http/https协议的数据交互

根据一定规则(如扩展名)确定是否需要调用php来处理这个请求,调用的方式有很多种,比如模块方式、CGI方式、以及基于CGI的fastcgi/fpm方式,取决于web server的配置

调用结束后,php把要返回的数据吐出来给web server,再由web server封装成http/https协议格式,返回给客户端/浏览器

首先需要知道你是用apache还是nginx做服务器,真正的请求是服务器去解析的。在服务器配置后就会直接交给php处理了。没用服务器的话请见@mao童鞋的答案

<code>$context = stream_context_create(array('ssl' =>array(
        'local_cert' =>'./https.pem',
    )));

if(!$server = stream_socket_server("ssl://0.0.0.0:2016", $err_no, $err_msg, STREAM_SERVER_BIND | STREAM_SERVER_LISTEN, $context)){
   exit($err_msg);
}

while(1){
    $client = stream_socket_accept($server);
    if ($client) {
        stream_set_blocking($client, 0);
        $in = '';
        while($ret = fread($client, 8192)) $in .= $ret;
        $response = "HTTP/1.0 200 OK\r\n\r\nHello";
        fwrite($client, $response);
        fclose($client);
    }
}

PHP也能写Socket服务器的,上面是用PHP写的一个极其简陋的HTTPS的WebServer,本地测试通过,浏览器访问 https://127.0.0.1:2016测试

代码放到github中 https://github.com/walkor/webserver-example
里面还有个HTTP协议的WebServer,仍然是极其简陋的Demo,ab压测结果如下,单核2.4W QPS

<code>Concurrency Level:      100
Time taken for tests:   4.082 seconds
Complete requests:      100000
Failed requests:        0
Write errors:           0
Total transferred:      3100000 bytes
HTML transferred:       1200000 bytes
Requests per second:    24498.50 [#/sec] (mean)
Time per request:       4.082 [ms] (mean)
Time per request:       0.041 [ms] (mean, across all concurrent requests)
Transfer rate:          741.65 [Kbytes/sec] received
</code>
