How to add custom soup message headers in gjs?

Question

I can't find any method in Soup.Message that would allow me to add custom headers. I tried adding headers using Message.requset_headers but that field is read only. How can I add custom header to my message?

Answer 1

Message.request_headers is read-only, but its value is a Soup.MessageHeaders instance, which has an append() method you can use to add a custom header.
