SOAP-ERROR:解析WSDL:无法加载 - 但适用于WAMP

This works fine on my WAMP server, but doesn't work on the linux master server!?

try{
    $client = new SoapClient('http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl', ['trace' => true]);
    $result = $client->checkVat([
        'countryCode' => 'DK',
        'vatNumber' => '47458714'
    ]);
    print_r($result);
}
catch(Exception $e){
    echo $e->getMessage();
}

What am I missing here?! :(

SOAP is enabled

Error

SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl' : failed to load external entity "http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl"/taxation_customs/vies/checkVatService.wsdl"

Call the URL from PHP

Calling the URL from PHP returns error

$wsdl = file_get_contents('http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl');
echo $wsdl;

Error

Warning:  file_get_contents(http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl): failed to open stream: HTTP request failed! HTTP/1.0 503 Service Unavailable

Call the URL from command line

Calling the URL from the linux command line HTTP 200 is returned with a XML response

curl http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl

    For some versions of php, the SoapClient does not send http user agent information. What php versions do you have on the server vs your local WAMP?

    Try to set the user agent explicitly, using a context stream as follows:

    try {
        $opts = array(
            'http' => array(
                'user_agent' => 'PHPSoapClient'
            )
        );
        $context = stream_context_create($opts);
    
        $wsdlUrl = 'http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl';
        $soapClientOptions = array(
            'stream_context' => $context,
            'cache_wsdl' => WSDL_CACHE_NONE
        );
    
        $client = new SoapClient($wsdlUrl, $soapClientOptions);
    
        $checkVatParameters = array(
            'countryCode' => 'DK',
            'vatNumber' => '47458714'
        );
    
        $result = $client->checkVat($checkVatParameters);
        print_r($result);
    }
    catch(Exception $e) {
        echo $e->getMessage();
    }
    

    Edit

    It actually seems to be some issues with the web service you are using. The combination of HTTP over IPv6, and missing HTTP User Agent string, seems to give the web service problems.

    To verify this, try the following on your linux host:

    curl  -A ''  -6 http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl
    

    this IPv6 request fails.

    curl  -A 'cURL User Agent'  -6 http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl
    

    this IPv6 request succeeds.

    curl  -A ''  -4 http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl
    curl  -A 'cURL User Agent'  -4 http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl
    

    both these IPv4 request succeeds.

    Interesting case :) I guess your linux host resolves ec.europa.eu to its IPv6 address, and that your version of SoapClient did not add a user agent string by default.
