PHP版极简反向访问网站源码

直接上代码


<?php
ignore_user_abort(true);
ob_start();
ob_clean();
$init = init();
function init()
{
  $init = null;
  $init['server'] = 'www.gua64.com';

  $init['host'] = explode(':', @$_SERVER['HTTP_HOST'])[0];
  $init['url'] = @$_SERVER['REQUEST_URI'];
  return $init; 
}
function getdata()
{
  global $init;
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, 'https://' . $init['server'] . $init['url']);
  curl_setopt($curl, CURLOPT_HEADER, FALSE);
  curl_setopt($curl, CURLOPT_TIMEOUT, 9);

配套.htaccess文件

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L]
</IfModule>

 

配套nginx伪静态

if (!-f $request_filename){
    set $rule_0 1$rule_0;
}
if ($rule_0 = "1"){
 rewrite ^/ /index.php last;
}

 

web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
      <rewrite>
        <rules>
          <rule name="a" stopProcessing="true">
            <match url="." ignoreCase="false" />
            <conditions>
              <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
            </conditions>
            <action type="Rewrite" url="/" />
          </rule>
        </rules>
      </rewrite>
    </system.webServer>
</configuration>
