How set proxy with username and password for `httpc` library?

Question

I've tried the following without success:

:httpc.set_options( proxy: {{'proxy.int.mycompany.com', 8080}, ['localhost'], proxy_auth: {'developer', 'developer'}})

And

:httpc.set_options(proxy:  { {'proxy.int.mycompany.com', 8080}, ['localhost'], {'proxy_auth', 'developer', 'developer'}})

Answer 1

:httpc.set_options/1 expects a proplist.

:httpc.set_options(
  proxy: {{'proxy.int.mycompany.com', 8080}, ['localhost']},
  proxy_auth: {'developer', 'developer'}
)
