Standard way to map a URL string to RFC Destination in ABAP?

Question

In SAP (AS ABAP 7.4) I have configured a set of RFC Destinations (Transaction SM59), including an SSL configuration using a client certificate for authentication at the service.

Say, one of these RFC Destinations goes to: myserver:443 and myserver requieres SSL client certificate authentication.

In my ABAP class I am given an arbitrary URL such as https://myserver:443/my/ressouce.xml

I am using CL_HTTP_CLIENT to fetch the ressource, but as far as I can see, there is no way to initialize the HTTP client in a way that it uses the correct SSL client certificate, except passing the appropriate RFC Destination using CL_HTTP_CLIENT.CREATE_BY_DESTINATION

To achieve this, one can manually read/parse the SAPs RFCDST table and map the given URL to the correct RFC destination.

My question is if there is a better way in SAP (eg a standard SAP function) than this manual approach?

Answer 1

The only viable way appears to be:

• "Manually" select the destination names from RFCDES with RFCTYPE = IF_DEST_ROOT~CO_TYPE_HTTP_EXT
• Parse the settings of each destination using RFC_READ_HTTP_DESTINATION
• Compare the values against the given URL - you will have to strip some part from either side, so that would have to be be custom code anyway.
