php soap wsdl 报错 DTD are not supported by SOAP 有大用 有大大用 有大大大用

Message = SoapFault exception: [Client] DTD are not supported by SOAP in D:\xampputf8\htdocs\mysoap\soap\soap_client-wsdl-ok.php:6 Stack trace: #0 D:\xampputf8\htdocs\mysoap\soap\soap_client-wsdl-ok.php(6): SoapClient->__soapCall('greet', Array) #1 {main}

1)很可能是 wsdl 文件里面  location 地址错了 

<wsdl:service name='helloService'>
<wsdl:port binding='impl:helloServiceSoapBinding' name='helloService'>
<wsdlsoap:address location='http://localhost/mysoap/soap/soap_client-non-wsdl-ok.php' />
</wsdl:port>
</wsdl:service>

2) 客户端和服务端 php 代码里面  关于 wsdl路径是否错了

客户端端代码 必须为相对路径

     soap_client-wsdl-ok.php 中 

$client = new SoapClient('http://my.mysoap.com/soap/hello-ok.wsdl');

服务端代码 可以为相对路径

     soap_server-wsdl-ok.php 中

$server = new SoapServer('hello-ok.wsdl');
