How to consume JSON-RPC service from ABAP

[Former Member]

Hi Experts,

We have a requirement to comunicate with a backend system with JSON-RPC.

Can a JSON-RPC service consumed from ABAP? JSON can be used in ABAP, but JSON-RPC?

Thanks in advance.

Hi Marcos,

we have the same demand to call a external JSON-RPC function by ABAP.

If your NetWeaver ABAP is >=7.40 or you have SAP NetWeaver gateway installed, there's a SE80 package called /IWBEP/JSON_RPC_CORE from Gateway Foundation Add-On.

This seems to be a JSON-RPC Implementation but it looks like not directly for client usage. May be you can resuse some utils or ideas from there in you code.

Best regards,

Hi Matthias,

correct, I saw that package too, but I didn't have the impresion that I could use the classes for calling an JSON-RPC service.

How will you implement your requirement?

Hi Marcos,

we use CL_REST_HTTP_CLIENT for http(s) and /ui2/cl_json=>serialize( ) to create well formed JSON.

With this JSON and the cl_http_utility=>set_request_uri() we generate a valid JSON RPC URL.

Best regards,

Matthias
