php获取网页请求状态程序代码,PHP页面跳转与跨站提交伪造Referer地址来源

方法一,使用 fsockopen

对于网页返回状态代码一般情况下我们都会去查自己网站状态码是不是200或错误页面是不是404代码,并且多数情况下我们的查看方法就是使用站长工具或ff浏览器等来查看,极少有人想到自己写一个查看状态代码的功能。

一、尝试过的URL跳转方法

严重鄙视curl_getinfo!

本文就此简述php获取网页请求状态程序示例如下:

 代码如下

 代码如下

方法一,使用 fsockopen (不推荐使用curl_getinfo!)

echo ‘<meta http-equiv=”refresh” content=”0; URL=’.$url.'”>’;

function get_http_code($url=”localhost”, $port=80,
$fsock_timeout=10){
    set_time_limit(0);
    ignore_user_abort(true);
 
    // 记录开始时间
    list($usec, $sec) =
explode(” “,
microtime(true));
    $timer[‘start’] = (float)$usec + (float)$sec;
 
    // 校验URL
   
if(preg\_match(“/^https?:\/\//i”,
$url)){
        $url = “;
    }
    // 支持HTTPS
    if(preg_match(“/^https:\/\//i”, $url)){
        $port = 443;
    }
 
    // 解析URL
    $urlinfo = parse_url($url);
    if(empty($urlinfo[‘path’])){
        $urlinfo[‘path’] = ‘/’;
    }
    $host = $urlinfo[‘host’];
    $uri = $urlinfo[‘path’] .
(empty($urlinfo[‘query’])?”:$urlinfo[‘query’]);
 
    // 通过fsock打开连接
    if(!$fp = fsockopen($host, $port, $errno, $error,
$fsock_timeout)){
        list($usec, $sec) = explode(” “, microtime(true));
        $timer[‘end’] = (float)$usec + (float)$sec;
        $usetime = (float)$timer[‘end’] – (float)$timer[‘start’];
 
        return array(‘code’=>-1, ‘usetime’=>$usetime);
    }
 
    // 提交请求
    $status = socket_get_status($fp);
    $out = “GET {$uri} HTTP/1.1\r\n”;
    $out .= “Host: {$host}\r\n”;
    $out .= “Connection: Close\r\n\r\n”;
    $write = fwrite($fp, $out);
    if(!$write){
        list($usec, $sec) = explode(” “, microtime(true));
        $timer[‘end’] = (float)$usec + (float)$sec;
        $usetime = (float)$timer[‘end’] – (float)$timer[‘start’];
 
        return array(‘code’=>-2, ‘usetime’=>$usetime);
    }
 
    $ret = fgets($fp, 1024);
    preg_match(“/http\/\d\.\d\s(\d+)/i”, $ret, $m);
    $code = $m[1];
    fclose($fp);
 
    list($usec, $sec) = explode(” “, microtime(true));
    $timer[‘end’] = (float)$usec + (float)$sec;
    $usetime = (float)$timer[‘end’] – (float)$timer[‘start’];
 
    return array(‘code’=>$code, ‘usetime’=>$usetime);
}

复制代码 代码如下:

echo ‘<scrīpt
language=”Javascrīpt”>window.location.href=”‘.$url.'”;</scrīpt>’;

file_get_contents 是 fsockopen
功能的简单打包,效率稍低些,但是抓取成功率很高,所以在 snoopy
出问题的时候我一般那他来。5.0.0 添加了对 context
的支持,有了context,他也可以发送 header 信息,自定义用户 agent,
referer, cookies 都不在话下。5.1.0 添加了 offset 和 maxlen
参数,可以只读文件的一部分内容。

function get_http_code($url=”localhost”, $port=80,
$fsock_timeout=10){
    set_time_limit(0);
    ignore_user_abort(true);

echo ‘<script
language=”Javascrīpt”>window.location.replace=”‘.$url.'”;</
script>’;

方法二,使用snoopy.class.php

    // 记录开始时间
    list($usec, $sec) = explode(” “, microtime(true));
    $timer[‘start’] = (float)$usec + (float)$sec;

以上三种方法均无法传递REFERER地址。

Snoopy是一个php类,用来模拟浏览器的功能,可以获取网页内容,发送表单。

    // 校验URL
    if(!preg_match(“/^https?:\/\//i”, $url)){
        $url = “;
    }
    // 支持HTTPS
    if(preg_match(“/^https:\/\//i”, $url)){
        $port = 443;
    }

二、使用PHP Socket函数伪造REFER
下面是PHP伪造REFERER代码部分,经过测试可以实现REFERER地址传递,其中$url是输入地址。

 代码如下

    // 解析URL
    $urlinfo = parse_url($url);
    if(empty($urlinfo[‘path’])){
        $urlinfo[‘path’] = ‘/’;
    }
    $host = $urlinfo[‘host’];
    $uri = $urlinfo[‘path’] .
(empty($urlinfo[‘query’])?”:$urlinfo[‘query’]);

 代码如下

$ch = curl_init();
curl_setopt($ch,
CURLOPT_URL, ”);
curl_setopt($ch, CURLOPT_RANGE, ‘0-500’);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
/**
*But as noted before if the server doesn’t honor this header but sends
the whole file curl will download all of it. E.g.
ignores the header. But you can (in addition) set a write function
callback and abort the request
when more data is received, e.g.
* php 5.3+ only
* use function writefn($ch, $chunk) { … } for earlier versions
*/
$writefn = function($ch, $chunk) {
  static $data=”;
  static $limit = 500; // 500 bytes, it’s only a test
  $len = strlen($data) + strlen($chunk);
  if ($len >= $limit ) {
    $data .= substr($chunk, 0,
$limit-strlen($data));
    echo strlen($data) , ‘ ‘, $data;
    return -1;
  }
  $data .= $chunk;
  return strlen($chunk);
};
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, ”);
curl_setopt($ch, CURLOPT_RANGE, ‘0-500’);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_WRITEFUNCTION, $writefn);
$result = curl_exec($ch);
curl_close($ch);

    // 通过fsock打开连接
    if(!$fp = fsockopen($host, $port, $errno, $error,
$fsock_timeout)){
        list($usec, $sec) = explode(” “, microtime(true));
        $timer[‘end’] = (float)$usec + (float)$sec;
        $usetime = (float)$timer[‘end’] – (float)$timer[‘start’];

$uinfo =
parse_url($url);//解析URL地址,比如

一些常见的状态码为:

        return array(‘code’=>-1, ‘usetime’=>$usetime);
    }

if($uinfo[‘path’]) //

200 – 服务器成功返回网页
404 – 请求的网页不存在
503 – 服务器超时
301 – 页面重定向

    // 提交请求
    $status = socket_get_status($fp);
    $out = “GET {$uri} HTTP/1.1\r\n”;
    $out .= “Host: {$host}\r\n”;
    $out .= “Connection: Close\r\n\r\n”;
    $write = fwrite($fp, $out);
    if(!$write){
        list($usec, $sec) = explode(” “, microtime(true));
        $timer[‘end’] = (float)$usec + (float)$sec;
        $usetime = (float)$timer[‘end’] – (float)$timer[‘start’];

    $data = $uinfo[‘path’];//这里得到/archives/1.html

        return array(‘code’=>-2, ‘usetime’=>$usetime);
    }

else

    $ret = fgets($fp, 1024);
    preg_match(“/http\/\d\.\d\s(\d+)/i”, $ret, $m);
    $code = $m[1];
    fclose($fp);

    $data = ‘/’;//默认根
