PHP:file_get_contents($ loc)失败 [英] PHP : file_get_contents($loc) fails

问题描述

我刚刚将一个项目从localhost移到了我的远程服务器上，并且注意到我的某些脚本停止工作了.最重要的是依靠file_get_contents()从另一个脚本中获取JSON值的

I just moved a project from localhost over to my remote server, and noticed that some of my scripts stopped working. Most importantly was one that relied upon file_get_contents() to fetch JSON values from another script.

PHP版本为5.2.4
allow_url_fopen已打开

PHP Version is 5.2.4
allow_url_fopen is ON

警告:file_get_contents() [function.file-get-contents]:php_network_getaddresses:getaddrinfo失败:line 5

警告:file_get_contents(http://data.example.com/new-data.php) [function.file-get-contents]:无法打开流:line 5上的Success in /var/www/html/2009/functions/functions.products.php

Warning: file_get_contents(http://data.example.com/new-data.php) [function.file-get-contents]: failed to open stream: Success in /var/www/html/2009/functions/functions.products.php on line 5

脚本从以下位置运行:http://www.example.com
传递给函数的位置是http://data.example.com/new-data.php

The script is being ran from: http://www.example.com
The location passed into the function is http://data.example.com/new-data.php

注意:相同的域名，但是两台不同的服务器.

Note: Same domain name, but two different servers.

function getData() {
  $location = "http://data.mysite.com/new-data.php";
  $contents = file_get_contents($location);
  $jsonVars = json_decode($contents);
  return $jsonVars
}

推荐答案

名称或服务未知

Name or service not known

DNS已损坏.您可以从计算机上的外壳(假设您有一个外壳)ping data.mysite.com吗?

DNS is broke. Can you ping data.mysite.com from a shell on the machine (assuming you have one)?

现在尝试用固定的IP地址替换data.mysite.com.

Try replacing data.mysite.com with a fixed IP address for now.
