Wrapping a SOAP API in REST

[Tharshan]

Hi, 

I was hoping this group could give me some advice on what the best way to approach wrapping a SOAP API through DRF and expose the resources found in the SOAP Schemas as REST endpoints. One of the issues is the creation of the classes and fields required for a each resource. Is there a way to generate classes by parsing the XML Schema of the SOAP API? Would you write a serialiser that translated back and forth between XML? To send the response in XML but also to receive a response in XML but send it back to the client as JSON.

Any ideas or suggestions are welcome.

Thanks

    I have a similar problem, I'll be providing an API that uses another RESTful API as its backend, but with semantics more useful to our organization. So far what I'm doing is to do the requests directly in the ViewSet, but not having any Model or Serializer, Should I create a custom DB backend, or is DRF not aimed at such type of projects?

Hi,

You're really trying to mix apples and oranges.

SOAP, is it says is "simple object access protocol" which is mainly meant to do RPC calls.

Now RESTful is just an architecture.

You just need to map several RPC calls to REST calls and you're done.

Calling SOAP from Python isn't easy task since depending on end SOAP point some libs do work better than other.

And in worst case I've seen so poorly generated SOAP that none of the Python SOAP libs couldn't talk to that.

So you have to think SOAP being something that you just call like functions in Python to return you some data. Which you then transform in proper format with DRF.
