type Handler ¶

type Handler func(context.Context) (net.Conn, error)

Handler is a http.Handler that proxies requests to an uWSGI backend that can be connected to using dialFunc.

Usage example:

network, addr := "unix", "/path/to/uwsgi.socket"
var d net.Dialer
fn := func(ctx context.Context) (net.Conn, error) {
	return d.DialContext(ctx, network, addr)
}
log.Fatal(http.ListenAndServe("localhost:8080", uwsgi.Handler(fn)))

Handler sets some uWSGI-specific variables:

QUERY_STRING
REQUEST_METHOD
CONTENT_TYPE
CONTENT_LENGTH
REQUEST_URI
PATH_INFO
SERVER_PROTOCOL
SERVER_NAME — value from the "Host:" header
HTTPS — only set to "on" if request has https scheme or
	X-Forwarded-Proto: https header
SERVER_PORT — set to "443" if request has https scheme or
	X-Forwarded-Proto: https header
REMOTE_ADDR — either address of connected peer, or leftmost value from
	X-Forwarded-For header if present
REMOTE_PORT — port of connected peer, if can be detected

Note the REMOTE_ADDR variable is populated from X-Forwarded-For if present — if server is exposed directly to the public network you may want to ensure this header is cleared before passing request to this Handler.
