肥皂错误致命错误：未捕获的SoapFault异常：[HTTP]无法连接到主机答案

【问题描述】：

我在使用 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

直接在/var/www/ 含义下移动文件时脚本运行良好：

http://localhost/soap-client.php

但是当我将它移动到名为phpwebservice 的子文件夹时，会出现该错误。子文件夹是这样的没关系：

http://localhost/phpwebservice/soap-client.php

或者如果我为它制作了一个虚拟主机：

http://phpwebservice/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：

    function getCatalogEntry($catalogId){
    if($catalogId == 'catalog1')
            return  "<html>
                <head>
                    <title>catalog</title>
                </head
                <body>
                <p> </p>
                    <table border=1>
                    <tr>

                    </table>
                </body>
            </html>";
elseif($catalogId == 'catalog2')
    return  "<html>

                    <table border=1>
                        <tr>
                            <th>catalogid</th>
                            <th>journal</th>

                    </table>
                </body>
            </html>";
    }
    ini_set("soap.wsdl_cache_enabled", "0");
    $server = new soapserver("catalog.wsdl");
    $server->addfunction("getCatalogEntry");
    $server->handle();

目录.wsdl：

【问题讨论】：

我想知道soap-server.php、catalog.wsdl 和soap-client.php 文件现在在哪里，您希望它们在哪里？
@raina77ow 他们都在同一个文件夹下 /var/www/phpwebservice/

标签： php web-services soap

【解决方案1】：

如果你是开发环境，最好在php.ini中设置soap.wsdl_cache_enabled=0。否则你必须在对 WSDL 文件进行任何更改后手动删除 WSDL 缓存（一般位于soap.wsdl_cache_dir 定义的目录中）

您也可以参考：SoapFault exception: Could not connect to host

【解决方案2】：

当我的SoapClient 选项中未指定connection_timeout 时，我遇到了特定SOAP 服务的这个问题。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);

【解决方案3】：

没关系，我只是从 wsdl 文件中的每一行中删除 /catalog，无论如何，现在一切正常。
