soap error致命错误：未捕获的SoapFault异常：[HTTP]无法连接到主机
[英]soap error Fatal error: Uncaught SoapFault exception: [HTTP] Could not connect to host
问题描述
I encounter this error when sending a SOAP request with the PHP SoapClient : 
使用PHP SoapClient发送SOAP请求时遇到此错误：
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: 在/var/www/含义下直接移动文件时，脚本工作正常：
http://localhost/soap-client.php
but when I move it to a sub-folder called phpwebservice that error appears. 但当我将它移动到一个名为phpwebservice的子文件夹时，会出现错误。 It doesn't matter if the sub-folder is like this: 子文件夹是这样的并不重要：
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
the content of soap-client.php : soap-client.php的内容：
$client = new SoapClient("catalog.wsdl");
$catalogId = 'catalog1';
$response = $client->getCatalogEntry($catalogId);
echo $response;
soap-server.php: 皂server.php：
function getCatalogEntry($catalogId){
if($catalogId == 'catalog1')
return "<html>
<head>
<title>catalog</title>
</head
<body>

}
ini_set("soap.wsdl_cache_enabled", "0");
$server = new soapserver("catalog.wsdl");

$server->handle();

If you're in the development environment, it's better to set soap.wsdl_cache_enabled=0 in php.ini . 如果您在开发环境中，最好在php.ini设置soap.wsdl_cache_enabled=0 。 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 ) 否则，您必须在对WSDL文件进行任何更改后手动删除WSDL缓存（通常位于soap.wsdl_cache_dir定义的目录中）

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

没关系，我只是从wsdl文件中的每一行中删除/ catalog，无论如何一切都正常。
