Index.php文件

Question

我解除了以下PHP代码，以便查找用户的位置信息，这将使我能够执行某些级别的限制。

但是，代码在我的localhost服务器上运行良好。但是当我将相同的php文件上传到我的远程Web服务器时，它会返回错误：

警告：的file_get_contents（http://api.codehelper.io/ips/?php&ip=192.168.1.1）：无法打开流：权限被拒绝 /home/www/xyberinternational.com/lotto247.biz/visitorlocation/userip/ip.codehelper.io.php 在第41行。

我在下面列出了以下文件及其代码。我该如何解决这个错误？

        return $data;
    }
}

同时，fastcatch.php非常大。

Answer 1

这是你的问题：

    $url = "http://api.codehelper.io/ips/?callback=codehelper_ip_callback&ip=".$ip;
    $data = file_get_contents($url);

（靠近ip.coderhelper.io.php文件的底部）

这会引发错误，因为您尝试从中获取数据的服务器拒绝您访问该文件。你有几个选择：

1）与codehelper.io工作人员交谈，看看你服务器的IP是否被列入黑名单或一般范围（有时候，取决于你从公司购买服务器的位置黑名单IP，因为他们知道发送出去恶意攻击或请求。让他们看看他们是否可以解决问题。

2）如果这不是一个可行的选择，你可以看看this post，第二个答案有一点hacky工作。值得一试。

file_get_contents（$ URL）返回“Permission Denied”错误
