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

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

直接将文件移动到/ var / www /下时,脚本可以正常工作：

http://localhost/soap-client.PHP

但是当我将其移动到名为PHPwebservice的子文件夹时,会出现错误.子文件夹是否像这样无关紧要：

http://localhost/PHPwebservice/soap-client.PHP

或者,如果我为此制作了VirtualHost：

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>

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

catalog.wsdl：

谢谢.

解决方法:

如果您处于开发环境中,最好在PHP.ini中设置soap.wsdl_cache_enabled = 0.否则,在对WSDL文件(通常位于soap.wsdl_cache_dir定义的目录中)进行任何更改之后,您必须手动删除WSDL缓存.
