使用PHP时尝试连接到FedEx Ship Service API时出错

Question

I had decided to integrate FedEx Shipping Service into one of my online apps. I downloaded a sample PHP code from the FedEX developer center. But when I tried to work with the ShipGroundDomestic.php5 I am getting error. I modified the file according to my specifications & plugged in the credentials. But I am unable to make it work. I am getting following error,

Fault Code:HTTP String:Could not connect to host

I have made sure that there are no file path issues & other related issues. But I am constantly getting this error. I was wondering if any of you guys have worked with this & would know how to resolve this. I tried contacting the FedEx guys but its unhelpful.

Answer 1

Have you done a packet capture to see if you are generating/sending packets or if it fails before that. If it fails to generate packets then check to make sure the app is resolving the URL properly.
