这篇文章主要介绍了PHP中使用curl伪造IP的简单方法,作者也提到了相关的一些缺陷,需要的朋友可以参考下
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("'%s' => '%s',\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($ch, CURLOPT_REFERER, 'http://blog.csdn.net/'); curl_setopt($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

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
