HomeBackend DevelopmentPHP TutorialThe function of using curl to forge IP in PHP

本篇文章主要介绍PHP中使用curl伪造IP的功能,感兴趣的朋友参考下,希望对大家有所帮助。

curl简介:curl是一个利用URL语法在命令行方式下工作的文件传输工具。它支持很多协议:FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE 以及 LDAP。curl同样支持HTTPS认证,HTTP POST方法, HTTP PUT方法, FTP上传, HTTP上传, 代理服务器, cookies, 用户名/密码认证, 下载文件断点续传等等,功能十分强大。
PHP中常用curl实现的功能:
   1、实现远程获取和采集内容
   2、实现PHP 网页版的FTP上传下载
   3、实现模拟登陆
   4、实现接口对接(API),数据传输等
   5、实现模拟Cookie等

   PHP使用CURL功能默认情况下PHP是不支持CURL功能的,需要在PHP.ini中开启该功能

; extension= php_curl.dll//首先去除前面的;分号,并重启Apache/IIS

使用curl伪造IP


我找到的IP拷贝到txt文件里,然后sed和awk处理了一下,分享一下我的awk处理脚本:

 #!/bin/awk -f 
   
  #运行前 
  BEGIN { 
    FS = " "; 
    count = 0; 
  } 
   
  #运行中 
  { 
    iparr[count ++] = $0; 
  } 
   
  #运行后 
  END { 
    printf("<?php\n"); 
    printf("$iparr = array(\n"); 
    for (i = 0; i < count; i ++) { 
      printf("&#39;%s&#39; => &#39;%s&#39;,\n", iparr[i], iparr[i]); 
    } 
    printf(");\n"); 
  }

CURL使用

<?php 
  require_once dirname(__FILE__) . "/iplib.php"; 
   
  $req_url = "test.com"; 
   
  foreach ($iparr as $forward => $cip) { 
     
    $ch = curl_init(); 
     
    curl_setopt($ch, CURLOPT_URL, $req_url); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array( 
        "X-FORWARDED-FOR:$forward", 
        "CLIENT-IP:$cip" 
    )); 
    curl_setopt($ch, CURLOPT_REFERER, &#39;http://blog.csdn.net/&#39;); 
    curl_setopt($ch, CURLOPT_HEADER, 1); 
     
    curl_exec($ch); 
     
    curl_close($ch); 
  }


缺陷
很多服务器端一般都采用了$_SERVER['REMOTE_ADDR']来获取客户端的真实ip,这是在传输层就已经决定的地址,无法通过CURL进行修改,好吧,貌似我也没帮朋友做成功这件事情,不过还是记录一下

总结:以上就是本篇文的全部内容,希望能对大家的学习有所帮助。
