SoapClient LibXMLError: failed to load external entity, SOAP-ERROR: Parsing WSDL: Couldn't load
提问by David
I am trying to establish a SOAP connection using the following PHP code, and it's failing at the point of the SoapClient construct:
我正在尝试使用以下 PHP 代码建立 SOAP 连接，但它在 SoapClient 构造点失败：
// 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:
这输出：

After 6 hours of headache, the ONLY solution is to download the WSDL files.
经过 6 个小时的头痛，唯一的解决方案是下载 WSDL 文件。
https://wsbeta.fedex.com/web-servicesand https://ws.fedex.com/web-services
https://wsbeta.fedex.com/web-services和 https://ws.fedex.com/web-services
It will always throw an error 500, because this is not the wsdl.
它总是会抛出错误 500，因为这不是 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.
从技术资源 -> FedEx WebServices For Shipping -> GetStarted（点击“Rate Services”，然后点击“Download WSDL or XML”）下载wsdls 后，您将需要在脚本中加载本地存储的 WSDL 并且一切正常就像一个魅力。
$this->_soapClient = new SoapClient("RateService_v13.wsdl", array('exceptions'=>true, 'trace' => true));
Have fun!

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 somewhereand 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 wsdlis somewhere else, the url you have is just the location of a particular service.
该 url 不是 WSDL 的路径，而是 SOAP 请求应该到达的 url。从来没有和这些人一起工作过，但我认为你可以在某处得到一个 wsdl 文件并将其存储在本地，你可以将该 wsdl 中的端点更改为 wsbeta 端点。我找不到 wsdl 并且联邦快递网站不允许我在没有注册的情况下进一步了解他们的开发技术资源，所以我将保留它：你wsdl在其他地方，你拥有的 url 只是他们的位置一项特定的服务。

You'll need a local certificate file to access a WSDL on HTTPS:
您需要一个本地证书文件来访问 HTTPS 上的 WSDL：
$client = new SoapClient($wsdl, array('local_cert' => $pathToLocalCert));
Append this option to your current $soap_argsand this code should work as expected. A passphraseoption is also available if you need it for the certificate.
将此选项附加到您的当前选项$soap_args，此代码应按预期工作。passphrase如果您需要证书，也可以使用一个选项。
