scheme(Req :: cowboy_req:req()) -> Scheme :: binary()
cowboy_req:scheme - URI scheme
scheme(Req :: cowboy_req:req()) -> Scheme :: binary()
Return the scheme of the effective request URI.
The scheme can also be obtained using pattern matching:
#{scheme := Scheme} = Req.
The Req object.
The scheme is returned as a binary. It is case insensitive.
Cowboy will only set the scheme to <<"http">> or <<"https">>.
init(Req0=#{scheme := <<"http">>}, State) ->
Req = cowboy_req:reply(302, #{
<<"location">> => cowboy_req:uri(Req, #{scheme => <<"https">>})
}, Req0),
{ok, Req, State};
init(Req, State) ->
{cowboy_rest, Req, State}.
