How can I submit a file to nginx?

Question

Nginx

I'm trying to send a file, via nginx:

ngx.req.set_header("Content-Disposition", "attachment; filename=qwe.txt")
ngx.say('{"code":"101","message":"empty token"}')

But when you click on the link, the page opens, and the file is not downloaded

Answer 1

ngx.req.set_header changes the request header, which is pretty pointless.
