用DirectAdmin反代Github加速Git

之前写过Nginx反代方法的,那么DirectAdmin行不行呢,当然可以,首先新建一个.htaccess文件,目的是重定向所有请求.

Header unset Upgrade
<ifModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
</ifModule>

然后在PHP中分别针对两种请求进行转发.

<?php

// 拼接URL
function GetUrl()
{
    $s = !isset($_SERVER['HTTPS']) ? '' : ($_SERVER['HTTPS'] == 'on') ? 's' : '';
    $protocol = strtolower($_SERVER['SERVER_PROTOCOL']);
    $protocol = substr($protocol,0,strpos($protocol,'/')).$s.'://';
    $port = ($_SERVER['SERVER_PORT'] == 80) ? '' : ':'.$_SERVER['SERVER_PORT'];
    $server_name = isset($_SERVER['SERVER_NAME']) ? $_SERVER['SERVER_NAME'].$port : getenv('SERVER_NAME').$port;
    $host = isset($_SERVER['HTTP_HOST']) ? strtolower($_SERVER['HTTP_HOST']) : $server_name; 
     $GetUrl=$protocol.$host.$_SERVER['REQUEST_URI'];
}

// 遍历请求头
function HeaderCallback($str){
    return strtoupper($str[0]);
}

function GetClientHeader(){
    $headers=array();
    foreach($_SERVER as $k=>$v){
        if(strpos($k,'HTTP_')===0){
            $k=strtolower(preg_replace('/^HTTP/', '', $k));
            $k=preg_replace_callback('/_\w/','header_callback',$k);
            $k=preg_replace('/^_/','',$k);
            $k=str_replace('_','-',$k);
            if($k=='Host') continue;
            $headers[]="$k:$v";
        }
    }
    return $headers;
}

function ParseHeader($ret){
    list($headerstr,$ret)=explode("\r\n\r\n",$ret, 2);
    $ret=array($headerstr,$ret);
    if(preg_match('/^HTTP\/1\.1 \d{3}/', $ret)){
        $ret=ParseHeader($ret);
    }
    return $ret;
}

$_REQUEST['url'] = GetUrl();

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://github.com/'.$_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);

if(!empty($_SERVER['HTTP_REFERER']))
    curl_setopt($ch,CURLOPT_REFERER,$_SERVER['HTTP_REFERER']);

$headers=GetClientHeader();
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers) ;
 
if( $_SERVER['REQUEST_METHOD']=='POST' )
{
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, file_get_contents('php://input'));
}

$ret = curl_exec($ch);
list($headerstr,$ret)=ParseHeader($ret);
$headarr= explode("\r\n", $headerstr);

foreach($headarr as $h){
    if(strlen($h)>0){
        if(strpos($h,'Content-Length')!==false) continue;
        if(strpos($h,'Transfer-Encoding')!==false) continue;
        if(strpos($h,'Connection')!==false) continue;
        if(strpos($h,'HTTP/1.1 100 Continue')!==false) continue;
        if(strpos($h,'Upgrade')!==false) continue;
        if(strpos($h,'Location')){
            header(str_replace('github.com',$_SERVER['SERVER_NAME'],$h));
        }else{
            header($h);
        }
    }
}

// 返回内容
echo $ret;

curl_close($ch);

当然缺点也很大,基本上能Clone多大的库,取决于你的DA资源限制(比如限制死的很容易Limit resources错误.)
