file_get_contents(): php_network_getaddresses: getaddrinfo 失败: 名称或服务未知 [英] file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known

问题描述

我正在尝试使用 xampp 服务器上我网站上的 PHP 脚本从服务器下载图像.

I'm trying to download an image from a server using a PHP script on my website on xampp server.

正在使用函数 file_get_contents 下载图像.

The image is being downloaded using the function file_get_contents.

服务器上下载的php代码为:

The php code for downloading on the server is:

if(isset($_GET['path']) && isset($_GET['username'])) {
    echo "path:".$_GET['path'];
    $temp = explode(".", $_GET['path']);
    $extension = end($temp);
    $fname="images/".$_GET['title'];
    $filenameIn  = $_GET['path'];
    $filenameOut = "" . $fname;
    $contentOrFalseOnFailure   = file_get_contents($filenameIn);
    $byteCountOrFalseOnFailure = file_put_contents($filenameOut,$contentOrFalseOnFailure);
}

但我收到此错误:

推荐答案

表示你的服务器无法连接外界

It means your server cannot connect to the outside world

考虑到 DNS 问题，这可能不会改变任何事情

This probably won't change anything given the DNS issues

因此，如果您有权限，请尝试将/etc/resolv.conf 文件中的名称服务器更改为其他名称服务器.

So, If you have permission, try changing the name servers in your /etc/resolv.conf file to other nameservers.
