soap error Fatal error: Uncaught SoapFault exception: [HTTP] Could not connect to host
提问by Yahya KACEM
I encounter this error when sending a SOAP request with the PHP SoapClient:
使用 PHP 发送 SOAP 请求时遇到此错误SoapClient：
Fatal error: Uncaught SoapFault exception: [HTTP] Could not connect to host in /var/www/phpwebservice/soap-client.php:6
Stack trace:
#0 [internal function]: SoapClient->__doRequest('__call('getCatalogEntry', Array)
#2 /var/www/phpwebservice/soap-client.php(6): SoapClient->getCatalogEntry('catalog1')
#3 {main} thrown in /var/www/phpwebservice/soap-client.php on line 6
the script works fine when moving the files directly under the /var/www/meaning:
直接在以下/var/www/含义下移动文件时，脚本工作正常：
http://localhost/soap-client.php
but when I move it to a sub-folder called phpwebservicethat error appears. It doesn't matter if the sub-folder is like this:
但是当我将它移动到一个名为phpwebservice该错误的子文件夹时。子文件夹是这样的也没关系：
http://localhost/phpwebservice/soap-client.php
or if I made a VirtualHost for it:
或者如果我为它制作了一个 VirtualHost：
http://phpwebservice/soap-client.php

$response = $client->getCatalogEntry($catalogId);
echo $response;

never mind i just remove the /catalog from every line that it's in from the wsdl file, everything works fine now thanx anyway.
没关系，我只是从 wsdl 文件中的每一行中删除 /catalog，现在一切正常，无论如何。

If you're in the development environment, it's better to set soap.wsdl_cache_enabled=0in php.ini. Otherwise you have to manually delete WSDL cache after doing any changes to WSDL file (generally located in the directory defined by soap.wsdl_cache_dir)
如果是开发环境，最好设置soap.wsdl_cache_enabled=0在php.ini. 否则，您必须在对 WSDL 文件（通常位于由 定义的目录中soap.wsdl_cache_dir）进行任何更改后手动删除 WSDL 缓存

I encountered this issue for a particular SOAP service when connection_timeoutwas not specified in my SoapClientoptions. Setting the timeout to 1 fixed the issue for me.
当我的选项中未指定connection_timeout时，我遇到了特定 SOAP 服务的此问题SoapClient。将超时设置为 1 为我解决了这个问题。
$wsdl = 'https://...';
$options [
'trace' => true,
'exceptions' => true,
'connection_timeout' => 1
];
$client = new SoapClient($wsdl, $options);
