我必须使用web服务，创建它的程序员给了我端点以及wsdl的链接。创建客户端的错误NuSoap
如何创建客户端？使用wsdl链接或端点？
当我尝试连接，我有以下的回报
"Warning: SoapClient::SoapClient(http://mv114.agraria.coop.br:50000/XISOAPAdapter/MessageServlet?channel=:BC_SOAP_CV:CC_SOAP_CV_Sender) [function.SoapClient-SoapClient]: failed to open stream: HTTP request failed!

代码：
require_once('nusoap.php');
$client = new SoapClient('http://mv114.agraria.coop.br:50000/XISOAPAdapter/MessageServlet?channel=:BC_SOAP_CV:CC_SOAP_CV_Sender');
//$client = new SoapClient('http: //mv114.agraria.coop.br:50000/dir/wsdl?p=ic/55b6a9155f353207b6e7c92f548bbb98');
$client->setHTTPProxy("http: //wmv114.agraria.coop.br",50000,"WSPO","WAgr9876");
$err = $client->getError();
if ($err){
echo "Error". $err.;
}
else
{
echo "OK!!";
}
