Ошибка parsing wsdl couldn t load from

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

Try enabling openssl extension in your php.ini if it is disabled.
This way I could access the web service without need of any extra arguments, i.e.,

$client = new SoapClient(url);

None of the above works for me, so after a lot of research, I ended up pre-downloading the wsdl file, saving it locally, and passing that file as the first parameter to SoapClient.

Worth mentioning is that file_get_contents($serviceUrl) returned empty response for me, while the url opened fine in my browser. That is probably why SoapClient also could not load the wsdl document. So I ended up downloading it with the php curl library. Here is an example

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $serviceUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$wsdl = curl_exec($ch);
curl_close($ch);

$wsdlFile = '/tmp/service.wsdl';
file_put_contents($wsdlFile, $wsdl);

$client = new SoapClient($wsdlFile);

You can of course implement your own caching policy for the wsdl file, so it won’t be downloaded on each request.

After hours of analysis reading tons of logs and internet, finally found problem.

If you use docker and php 7.4 (my case) you probably get error because default security level in OpenSSL it too high for wsdl cert. Even if you disable verify and allow self-signed in SoapClient options.

You need lower seclevel in /etc/ssl/openssl.cnf from DEFAULT@SECLEVEL=2 to

DEFAULT@SECLEVEL=1

Or just add into Dockerfile

RUN sed -i "s|DEFAULT@SECLEVEL=2|DEFAULT@SECLEVEL=1|g" /etc/ssl/openssl.cnf

Source: https://github.com/dotnet/runtime/issues/30667#issuecomment-566482876

You can verify it by run on container

curl -A 'cURL User Agent' -4 https://ewus.nfz.gov.pl/ws-broker-server-ewus/services/Auth?wsdl

Before that change I got error:

SSL routines:tls_process_ske_dhe:dh key too small

It was solved for me this way:

Every company from which you provide «Host» has a firewall.

This error occurs when your source IP is not defined in that firewall.
Contact the server administrator to add the IP.

Or the target IP must be defined in the server firewall whitelist.

Below solution worked for me.

1- Go to php.ini in ubuntu with apache is /etc/php/7.4/apache2
( note: you should use your php version replace by 7.4 )

2- Remove ; from this line ;extension=openssl to make in uncommented.

3- Restart your web server sudo service apache2 restart

I use the AdWords API, and sometimes I have the same problem.
My solution is to add
ini_set(‘default_socket_timeout’, 900);
on the file
vendorgoogleadsgoogleads-php-libsrcGoogleAdsApiAdsSoapClient.php line 65

and in the
vendorgoogleads-php-libsrcGoogleAdsApiAdwordsReportingv201702ReportDownloader.php line 126
ini_set(‘default_socket_timeout’, 900);
$requestOptions[‘stream_context’][‘http’][‘timeout’] = «900»;

Google package overwrite the default php.ini parameter.

Sometimes, the page could connect to ‘https://adwords.google.com/ap
i/adwords/mcm/v201702/ManagedCustomerService?wsdl and sometimes no.
If the page connects once, The WSDL cache will contain the same page, and the program will be ok until the code refreshes the cache…

Adding ?wsdl at the end and calling the method:

$client->__setLocation('url?wsdl'); 

helped to me.

I might have read all questions about this for two days. None of the answers worked for me.

In my case I was lacking cURL module for PHP.

Be aware that, just because you can use cURL on terminal, it does not mean that you have PHP cURL module and it is active.
There was no error showing about it. Not even on /var/log/apache2/error.log

How to install module:
(replace version number for the apropiated one)

sudo apt install php7.2-curl
sudo service apache2 reload

I had the same problem

From local machines everything work (wamp + php5.5.38 or vagrant + php 7.4), but from prod linux server I had 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"

From redirect path plugin in chrome I discovered permanent redirect to https, but change url to https doesnt help.

Status Code    URL    IP    Page Type    Redirect Type    Redirect URL    

301 http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl 147.67.210.30 server_redirect permanent https://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl
200 https://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl 147.67.210.30 normal none none

After few attempts of different code solutions helped my our server provider. He discovered problem in IP forwarding with ipv6.

http://ec.europa.eu/

Pinging ec.europa.eu [147.67.34.30] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.

Recommendation was user stream_context_create with socket and bind to 0:0. this forces ipv4

// https://www.php.net/manual/en/context.socket.php

$streamContextOptions = [
  'socket' => [
    'bindto' => '0:0'
  ],
];

$streamContext = stream_context_create($streamContextOptions);

$soapOptions = [
  'stream_context' => $streamContext
];

$service = new SoapClient('https://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl', $soapOptions);

I had similar error because I accidently removed attribute
[ServiceContract] from my contract, yet the service host was still opening successfully. Blunders happen

May try to see if the endpoint supports https as well

I’m trying to get all products in $productArrarray from magento 2 API via SOAP client. I tried the below function but it throws this error:

        $token = $request->integrationAdminTokenServiceV1CreateAdminAccessToken(array("username"=>"user", "password"=>"pass"));
        $opts = array(

            'cache_wsdl' => WSDL_CACHE_NONE
        );
        libxml_disable_entity_loader(false);

        $soapClient = new SoapClient($wsdlUrl, ['version' => SOAP_1_2, 'context' => $soapClientOptions]);
        var_dump($soapClient);exit;
        $soapResponse = $soapClient->__getFunctions();


    } catch (Exception $e) {

      $this->forward404($e->getMessage());
    }
