file_get_contents ($URL) 返回“权限被拒绝”错误

Question

我解除了以下 PHP 代码以使我能够找到用户的位置信息，这将使我能够执行某些级别的限制。

但是，该代码在我的本地主机服务器上运行良好。但是当我将相同的 php 文件上传到我的远程 Web 服务器时，它会返回一个错误：

警告： 文件获取内容（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。

我在下面包含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 相当大。

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，看看您的服务器的 IP 是否被列入黑名单或一般范围是否（有时，取决于您从公司购买服务器的位置，将 IP 列入黑名单，因为已知它们会发送恶意攻击或请求。）。询问他们是否可以解决问题。

2）如果这不是一个可行的选择，您可以查看this post，第二个答案有一些棘手的工作。值得一试。
