JetBrains License Server PHP版

PhpStorm 是我常用的IDE
ReSharper 是帮助VS成为更佳的IDE
上面这两个软件已经成为了我现在开发中不可缺失的软件了

之前一直使用lanyus提供的授权服务器，但是这些域名都已遭JetBrains封杀。
自己有不想单独去运行lanyus提供的本地版本。所以一直使用别人提供的域名，但是不怎么稳定，所以自己考虑使用PHP写一个。

使用需要注意的

1. 需要开启openssl
2. 可以直接使用php运行

授权服务类

<?php

/**

class JetBrainsLicenseServer
{
    // 授权给谁
    public $licensee = 'qlwz';
    // license 有效时间（单位：毫秒），默认约为7天多（607875500），原厂server传递的数值。
    public $prolongationPeriod = 607875500;
    // RSA 私钥
    public $privateKey = <<<Eof

Eof;

    public function ping($salt, $isAnswer = false)
    {
        $str = '<PingResponse><message></message><responseCode>OK</responseCode><salt>%s</salt></PingResponse>';
        $out = sprintf($str, $salt);
        return $isAnswer ? $this->writeAnswer($out) : $out;
    }

    public function obtainTicket($salt, $isAnswer = false)

        $ticketId = 1;
        $str      = "<ObtainTicketResponse><message></message><prolongationPeriod>%u</prolongationPeriod><responseCode>OK</responseCode><salt>%s</salt><ticketId>%d</ticketId><ticketProperties>licensee=%s\tlicenseType=0\t</ticketProperties></ObtainTicketResponse>";
        $out      = sprintf($str, $this->prolongationPeriod, $salt, $ticketId, $this->licensee);
        return $isAnswer ? $this->writeAnswer($out) : $out;
    }

    public function prolongTicket($salt, $isAnswer = false)
    {
        $ticketId = 1;
        $str      = '<ProlongTicketResponse><message></message><responseCode>OK</responseCode><salt>%s</salt><ticketId>%d</ticketId></ProlongTicketResponse>';
        $out      = sprintf($str, $salt, $ticketId);

    public function releaseTicket($salt, $isAnswer = false)

    public function writeAnswer($str)
    {
        $signature    = $this->sign($str);
        $signatureHex = bin2hex($signature);
        $out          = sprintf("<!-- %s -->\n%s", $signatureHex, $str);
        return $out;
    }

    private function sign($data)
    {
        if (empty ($data)) {
            return null;
        }
        $pkeyid = openssl_get_privatekey($this->privateKey);
        if (empty ($pkeyid)) {
            return null;
        }
        $signature = '';
        $verify    = openssl_sign($data, $signature, $pkeyid, OPENSSL_ALGO_MD5);
        openssl_free_key($pkeyid);
        return $verify ? $signature : null;
    }

}

使用JetBrainsLicenseServer类

<?php

include 'JetBrainsLicenseServer.php';

$uri = htmlspecialchars($_SERVER['REQUEST_URI']);
if (stripos($uri, '/rpc/ping.action') !== false) {
    $method = 'ping';
} elseif (stripos($uri, '/rpc/obtainTicket.action') !== false) {
    $method = 'obtainTicket';
} elseif (stripos($uri, '/rpc/prolongTicket.action') !== false) {
    $method = 'prolongTicket';
} elseif (stripos($uri, '/rpc/releaseTicket.action') !== false) {
    $method = 'releaseTicket';
} else {
    show404();
    exit();
}
$jblicsvr = new JetBrainsLicenseServer();
$salt     = htmlspecialchars(isset ($_GET['salt']) ? $_GET['salt'] : null);
if (!$salt) {
    if (preg_match('/(&amp;|&|\?)salt=(?<salt>.*?)(&|$)/', $uri, $result)) {
        $salt = $result['salt'];
    }
}

if (!$salt || !method_exists($jblicsvr, $method)) {
    show404();
}
echo $jblicsvr->$method ($salt, true);
exit();

function show404($msg = '')
{
    $protocol = htmlspecialchars($_SERVER['SERVER_PROTOCOL']) ?: 'HTTP/1.0';
    header($protocol . ' 404 Not Found');
    header('Status: 404 Not Found');
    echo $msg ?: 'Not Found';
    exit ();
}

使用重定向

RewriteRule ^rpc/(ping|obtainTicket|prolongTicket|releaseTicket).action$ jblicsvr.php [QSA,PT,L]

使用方法

1. 软件授权软件选择License server
2. Licese server address填写
   a. http://xxxx/jblicsvr.php?
   b. http://xxxx/jblicsvr.php (如果使用该地址出错，则使用上面的地址)
   c. http://xxxx (使用重定向后)
