错误为：SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://xxxxx/api?wsdl' : failed to load external entity "https://xxxxxxx/api?wsdl" in D:\www\compare.php:22 Stack trace: #0 D:\www\compare.php(22): SoapClient->SoapClient('https://xxx...', Array) #1 {main}

代码如下：

$opts =array('http' => array('user_agent' => 'PHPSoapClient'),'ssl'=>array('verify_peer'=>false ,'verify_host'=>false,"verify_peer_name"=>false));

$url="https://xxxxxxx/api?wsdl";

$params= array('encoding' => 'UTF-8','soap_version'=>SOAP_1_1,'trace' => 1, "exceptions" => 1, "connection_timeout" => 180,'username' => 'xx', 'password' => '*****','stream_context' => stream_context_create($opts));

$client =new SoapClient($url,$params);

另外php.ini配置没有问题，openssl和soap已经打开

请问下各位大佬，怎么解决？？？？
