php soapclient wsdl SOAP-ERROR: Parsing WSDL: Couldn't load from

Question

I have googled and looked here in stackoverflow but I have not found a solution to my specific problem. I keep getting the error

 SOAP-ERROR: Parsing WSDL: Couldnt load from "https://sampleurl.com/MerchantQueryService.asmx?WSDL" : failed to load external entity "https://sampleurl.com/MerchantQueryService.asmx?WSDL"

I am trying to use a SOAP API with a URL like

https://sampleurl.com/MerchantQueryService.asmx?WSDL

I am running MAMP on my localhost and using godaddy shared hosting, I have tried on both with the wsdl file can be found here

http://clemdemo.com/test.wsdl

In PHP I use the code below

error_reporting(-1);
ini_set('display_errors', 'On');
ini_set('soap.wsdl_cache_enabled', 0);

echo "<pre>";

try {

$url     = "https://sampleurl.com/MerchantQueryService.asmx?WSDL ";
$headers = [
    'Host: sampleurl.com',
    'Connection: Keep-Alive',
    'User-Agent: PHP-SOAP/5.3.29',
    'Content-Type: text/xml; charset=utf-8',
    'SOAPAction: "RequestTransaction"',
    'Content-Length: 409'];

$rq = [
"userName" => "username_here",
"passWord" => "password_here",
"referenceId" => "3455566694",
"msisdn" => "346774313"];


try {

$cient = new SoapClient($url,
    [
    'soap_version' => SOAP_1_2,
    'exceptions' => 1,
    'cache_wsdl' => WSDL_CACHE_NONE,
    'trace' => 1,
    'stream_context' => stream_context_create(array('http' => array('header' => $headers)))
]);

print_r($cient);
} catch (SoapFault $e) {
    echo "\nFault Code: ".$e->faultcode;
    echo "\nFault String: ".$e->faultstring;
}

On my MAMP localhost i have SOAP,openssl and curl.

ALSO, I tried using (sending request) to the API with an online WSDL http://wsdlbrowser.com it WORKS but on code using PHP it fails

It often happens that providers neglect their SSL certificates and hence the sites and services end up having an invalid certificates - I suspect this is the case here.

Disabling the certificate validation as described by Kaii here or even better get your provider to fix their certificate.

Your code could/should then be something like:

$url     = "https://sampleurl.com/MerchantQueryService.asmx?WSDL ";
$context = stream_context_create(array(
        'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
        )
));

$rq = ["userName" => "username_here",
       "passWord" => "password_here",
       "referenceId" => "3455566694",
       "msisdn" => "346774313"];

$service = new SoapClient($url, array('stream_context' => $context));
$service->RequestTransaction($rq);

The error message appears to say that your app is not able to read our WSDL. Try opening a browser from the same machine on which your app is running and see if you can access the WSDL address at https://sampleurl.com/MerchantQueryService.asmx?WSDL.

If not - you have a network/firewall/Anti Virus problem. (in case)

If you can access this address from a browser - is your app still experiencing this problem? then check any app that could be hindering your firewall.(Anti virus are most probable cause)

If you use docker there is a chance you get error because of OpenSSL default security level. Even if you disable verify and allow self-signed in SoapClient options.

Try out to 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

By: 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

Better diagnostics can be performed with: libxml_get_last_error();
Could have cached a bad response, set 'cache_wsdl' => WSDL_CACHE_NONE when initating the object
if you skip cache, and get this in your libxml error:

LibXMLError Object ( [level] => 1 [code] => 1549 [column] => 0 [message] => failed to load external entity "URL" [file] => [line] => 0 )

With no description on Ubuntu, then its not pulling the file period. You just got hit with the Ubuntu update. Wave them the bronx salute and reboot.
