PHP - SOAP “Parsing WSDL: Couldn't load from …” Error

Question

This is my code:

$this->options = [
    "login" => $username,
    "password" => $password
];
try {
    $this->request = new SoapClient('https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl', $this->options);
} catch(Exception $e) {
    throw new Exception($e->getMessage());
}

And this is the error message:

Fatal error: Uncaught Exception: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl': failed to load external entity "https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl"

Any idea how I can fix this error?

[UPDATE]

I can get functions with this code:

$wsdl = file_get_contents('https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl');

But this code still gets error:

SoapClient('https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl', $this->options);

Answer 1

try from command line:

wget https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl

or

php -r '$a = new SoapClient("https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl"); var_dump($a);'

Maybe resource id not available from tour host

Answer 2

To handle SOAP exceptions, you can give this answer a try. Following code is standalone code which is returning a SOAP response.

 $params = array(
    "login" => "USERNAME",
    "password" => "PASSWORD"
);
try {
    $client = new SoapClient('https://servis.turkiye.gov.tr/services/g2g/kdgm/test/uetdsesya?wsdl', array($params));
} catch(Exception $e) {
    throw new Exception($e->getMessage());
}

To List all available SOAP functions:

echo " List of available SOAP functions <br/><pre>"; var_dump($client->__getFunctions()); echo "</pre>";

To List all available SOAP types:

echo "List of SOAP types <br/><pre>"; var_dump($client->__getTypes()); echo "</pre>";

This answer has an explanation about how to access any available SOAP function.
