curl and/or soap

blackhorse

I used to use curl to exchange the xml information between the shopping sites and payment gateway service sites.

But soap is for exchange info too, such as nusoap.

My questions are

1) in what cases we better use curl? in what cases we better use soap? or doesn't matter, they both works?

2) or some cases, we better use both curl and soap, for example?

If I am not mistaken, SOAP is just an XML messaging protocol and cURL is a sort of networking library.

So, you can use cURL to send SOAP messages.

I have used cURL and SOAP, but I don't think I can answer your questions. However, I've found it easier to do stuff with SOAP using SOAP classes.

I used the curl to download, ftp upload files, exchange xml files etc.

I also used curl to grab the latitude and longitude information from returned xml file by passing an address etc. in the request. But I also used soap to do the same works, get latitude and longitude from address. In this case, curl or soap did the same kind jobs. Depending on which service the server side offers.

I didn't use the curl to send soap messages yet. I will check that out. I was wondering why we need curl to send soap messages. soap itself has a server script, and client script, client script makes a request to the server script calling its function and get the returns. soap itself is for send and receive messages.

Thanks!

You don't. Like you said, most SOAP packages have internal handlers for the server communications. However, there have been times I have found it easier to copy and paste "sample SOAP code" and send it across using cURL than recreating it in a SOAP package.

There are a lots of ways to do the same thing, it's just which ever is easiest and most useful at the time I guess.
