Php 无法打开流：HTTP请求失败！HTTP/1.0 503服务不可用,php,Php,我以root用户身份连接到服务器，我有一个简单的php脚本： <?php $url ="http://www.ec.europa.eu/taxation_customs/vies/checkVatService.wsdl"; fopen($url, 'r'); ?> 请注意，当我尝试另一个url exp:script时，它不会显示任何警告或错误，当我在浏览器中键入所需的url时，它也会工作。我检查了php.ini，变量allow\u url\u fopen已经设置为On。从另一

我以root用户身份连接到服务器，我有一个简单的php脚本：

<?php
$url ="http://www.ec.europa.eu/taxation_customs/vies/checkVatService.wsdl";
fopen($url, 'r');
?>

请注意，当我尝试另一个url exp:script时，它不会显示任何警告或错误，当我在浏览器中键入所需的url时，它也会工作。我检查了php.ini，变量

allow\u url\u fopen

已经设置为

On

。从另一台服务器上，我尝试了相同的脚本（相同的url），它工作正常，因此问题与我的服务器有关，而不是与所需的服务有关。你知道如何避免这种情况吗
