Force nginx to send specific Content-Type

Question

How to overwrite default Content-Type in nginx? Currently when I request 01.dae file, there's

Content-Type: application/octet-stream;

And I want it to be

Content-Type: application/xml;

I tried something like

location ~* \.dae$ {
  types { };
  default_type application/xml;
}

and

location ~* \.dae$ {
  add_header Content-Type application/xml;
}

but nothing works.

Answer 1

You can edit /etc/nginx/mime.types and add it

types {
    application/xml        dae;
}

I haven't found the the exact string application/xml in my mime.types so I suppose you can directly include it inside your server block, in the server scope or something.

Answer 2

In case when you have no file extension:

location ~ something {
   default_type application/xml;
}

In case you are setup let's encrypt certificate with client which creates http server: How to use golang lego let's encrypt client behind nginx?

Answer 3

Add "the application/xml dae;" to your server scope or location scope. Or add it into the mime.type.

Both of them work for me.
