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!

//Carl

You can use SAP Cloud SDK to get raw response for your request and then parse it as per you needs.

I had to use this to get the CSRF token when calling an S/4HANA Cloud API.
