Magento SOAP-ERROR：解析 WSDL - 通过 cron

Question

I have an ERP using the magento SOAP API v2 ( http://www.example.com/api/v2_soap/?wsdl ). Through my local server, crons access every minute the API and synchronize data.

Everything always worked very well until one day just stopped working, firing the error:

Symfony\\Component\\Debug\\Exception\\FatalErrorException: SOAP-ERROR: Parsing WSDL: Couldn't load from ' http://www.example.com/api/v2_soap/?wsdl ' : failed to load external entity " http://www.example.com/api/v2_soap/?wsdl "

When worked, this error happened a few times an hour, but now it always happens.

My server is a ubuntu 16.04 and use the laravel framework 5.2.

The big problem is that if I access the api in my local server by curl for example, everything works, but with cron stopped working.

I know there are many questions on this subject, but none solved my problem.

Thanks.

我以前遇到过这种情况，不得不将soap服务器（您的Magento机器）的主机名放在/etc/hosts文件中，因为在进行soap调用时，服务器必须能够自行解析。
