Accessing response headers from remote service calls in CAP

[carlonnheim]

Hi,

I have a scenario where I need to access the remote service response headers after having made a call like so

const svc = await cds.connect.to('someservice')

let results = svc.tx(req).send(somequery);
// Here, results contains the parsed response payload, but I cannot find the response headers

What is the appropriate way to do this? I have tried constructing a cds.Request first and then emitting it, but I cannot find the headers anywhere in the request object after the call completes either.

Thanks!

Hi,

this is unfortunately not possible right now.

Ok, is it planned for the future? It can be worked around either by "patch-package" or using the cloud-sdk in these scenarios for example, but it is inconvenient.

Thanks!

sambr do you happen to know if there's any update on this? Interacting e.g. with Variant Configuration (https://api.sap.com/api/ProductConfigurationService/overview) you need to fetch some values out of the header of one of the requests to pass into further requests.

No it's not possible, you can add a custom handler though and do all the communication with the backend service yourself.
