SoapClient LibXMLError: failed to load external entity, SOAP-ERROR: Parsing WSDL: Couldn't load

Question

I am trying to establish a SOAP connection using the following PHP code, and it's failing at the point of the SoapClient construct:

// Need to declare these settings here because our php.ini has alternate
// settings due to global purposes for other PHP scripts
ini_set("soap.wsdl_cache_enabled", "0");
ini_set("soap.wsdl_cache", "0");
ini_set("display_errors","On");
ini_set("track_errors","On");

// FedEx web services URL, note the HTTPS
$path_to_wsdl = 'https://wsbeta.fedex.com/web-services';

$soap_args = array(
    'exceptions'=>true,
    'cache_wsdl'=>WSDL_CACHE_NONE,
    'trace'=>1)
;

try {
    $client = new SoapClient($path_to_wsdl,$soap_args);
} catch (SoapFault $e) {
    var_dump(libxml_get_last_error());
    echo "<BR><BR>";
    var_dump($e);
}

This outputs:

Solution 1

After 6 hours of headache, the ONLY solution is to download the WSDL files.

https://wsbeta.fedex.com/web-services and https://ws.fedex.com/web-services

It will always throw an error 500, because this is not the wsdl.

Once you download the wsdls from Technical Resources -> FedEx WebServices For Shipping -> GetStarted (click on "Rate Services" and then "Download WSDL or XML"), in your script you will need to load your locally stored WSDL and everything will work like a charm.

$this->_soapClient = new SoapClient("RateService_v13.wsdl", array('exceptions'=>true, 'trace' => true));

Have fun!

Solution 2

That url is NOT the path to a WSDL , but the url the SOAP requests should be going to. Never worked with the guys, but I gather you can get a wsdl file somewhere and store it locally, and you can alter the endpoint in that wsdl to the wsbeta one. I cannot find the wsdl's and the fedex site doesn't allow me to go further in their dev technical resources without signing up, so I'll leave it at that: you wsdl is somewhere else, the url you have is just the location of a particular service.

I already was doing so, and I removed that option because it wasn't making a difference. The cert had no impact whatsoever on the output.

Is allow_url_fopen enabled on php.ini settings?

[David]

Yes, allow_url_fopen is enabled

[David]

alganet, BTW - I've seen conflicting answers about the 'local_cert': should it be the path to the file, or a "file_get_contents($path)" to provide a string with the contents of the cert? (Neither has worked for me but I'd appreciate your feedback anyway, for my future reference.)

Thanks Justin. This is what I eventually found out to be true myself, and as I read back over this original post, I never closed it out with the correct answer noted. Yours is indeed the correct solution, which I find after hours of beating my head against the wall as well. The FedEx documentation is horribly lacking in this regard.

Thanks Wrikken. As noted on Justin's answer, I checked his because it was more precise and complete as it related to my problem, but your answer is also correct.
