fopen失败，getaddrinfo失败 [英] fopen fails with getaddrinfo failed

问题描述

我在使用以下代码时遇到问题:

I am having problems with the following code:

function http_file_exists($url){
$f=fopen($url,"r");
if($f){
    fclose($f);
    return true;
} else {
  return false;
}

} $ url ="http://www.minhemmelighed.dk/Graphics/Products/55.jpg";

} $url = "http://www.minhemmelighed.dk/Graphics/Products/55.jpg";

打印http_file_exists($ url);

print http_file_exists($url);

它返回的错误是:

警告:fopen():php_network_getaddresses:getaddrinfo失败:名称或服务在第6行的/srv/http/webshop3/image_scraper/test.php中未知警告:fopen(http://www.minhemmelighed.dk/Graphics/Products/55.jpg):无法打开流:php_network_getaddresses:getaddrinfo失败:名称或服务在第6行的/srv/http/webshop3/image_scraper/test.php中未知

Warning: fopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /srv/http/webshop3/image_scraper/test.php on line 6 Warning: fopen(http://www.minhemmelighed.dk/Graphics/Products/55.jpg): failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known in /srv/http/webshop3/image_scraper/test.php on line 6

对此我该怎么办?我已经多次重启服务器.

What can I do about this? I have rebooted the server several times.

记录下来:

我可以通过浏览器访问有问题的网站

I can access the website in question through a browser

我正在Arch Linux上运行LAMP

推荐答案

重新引导UNIX服务器极不可能解决问题.看来您需要检查服务器上的名称服务器配置.在Web服务器的控制台上(以php用户身份登录，可能是apache或www-data)，进行测试

Rebooting a UNIX server is extremely unlikely to fix a problem. It looks like you need to check your nameserver configuration on the server. On the console of the web server (logged in as the php user, probably apache or www-data), test

dig www.minhemmelighed.dk

如果输出错误消息，请检查您的/etc/resolv.conf.注释掉所有行并添加

If this outputs an error message, check your /etc/resolv.conf. Comment out all lines and add

nameserver 8.8.8.8 # Google's public DNS server

如果这可以解决问题，请与原始名称服务器的管理员联系(或仅使用Google的8.8.8.8).如果没有，请检查您的连接和防火墙.

If that solves the problem, contact the administrator of the original nameserver (or just use Google's 8.8.8.8). If it doesn't, check your connectivity and firewalls.
