How to write Content-type to Go server HTTP response header?

Question

go

Please help me to write Content-type in HTTP response header of Go-server!
I did this:
var contType = "text/css; charset=UTF-8"
w.Header().Add("Content-Type", contType)
but it doesn't seem to work... - browsers load files correctly after three times ( basically mistaking CSS for JS).
In general, the task is to ensure that the files sent by my Go-server are correctly recognized by browsers.

Answer 1

Are you calling
w.Header().Add("Content-Type", contType)
before calling
w.WriteHeader(status)
?
After the
w.WriteHeader(status) function,
writing something in the headers is useless.
Also, if you are serving files through the th server, use http.FileServer

it will set the Content-Type of the files for you.

Hey!
w.Header().Set("Content-Type", "application/json")
