下面是我的代码

$client = new SOAPClient ( 'http://torcache.net/torcache.wsdl');
    var_dump($client->cacheTorrent());

我在$client的var_dump之后得到了这个

object(SoapClient)#1 (2) { ["_soap_version"]=> int(1) ["sdl"]=> resource(1) of type (Unknown) }

然而，当我试图查找var_dump（$client-〉cacheTorrent（））时，我收到了这个消息;未捕获的SoapFault异常：[HTTP]未找到
但这对我来说毫无意义，因为我下载了WDSL文件，它明确地说操作CacheTorrent存在!!
这里

知道为什么我会得到这个错误吗？
