Variables

var ErrNoCachedConn = errors.New("h2quic: no cached connection was available")

ErrNoCachedConn is returned when RoundTripper.OnlyCachedConn is set

Functions

func ListenAndServe

func ListenAndServe(addr, certFile, keyFile string, handler http.Handler) error

ListenAndServe listens on the given network address for both, TLS and QUIC connetions in parallel. It returns if one of the two returns an error. http.DefaultServeMux is used when handler is nil. The correct Alt-Svc headers for QUIC are set.

func ListenAndServeQUIC

func ListenAndServeQUIC(addr, certFile, keyFile string, handler http.Handler) error

ListenAndServeQUIC listens on the UDP network address addr and calls the handler for HTTP/2 requests on incoming connections. http.DefaultServeMux is used when handler is nil.

Types

type RoundTripOpt

type RoundTripOpt struct {
	// OnlyCachedConn controls whether the RoundTripper may
	// create a new QUIC connection. If set true and
	// no cached connection is available, RoundTrip
	// will return ErrNoCachedConn.
	OnlyCachedConn bool
}

RoundTripOpt are options for the Transport.RoundTripOpt method.

type RoundTripper

type RoundTripper struct {

	// DisableCompression, if true, prevents the Transport from
	// requesting compression with an "Accept-Encoding: gzip"
	// request header when the Request contains no existing
	// Accept-Encoding value. If the Transport requests gzip on
	// its own and gets a gzipped response, it's transparently
	// decoded in the Response.Body. However, if the user
	// explicitly requested gzip it is not automatically
	// uncompressed.
	DisableCompression bool

	// TLSClientConfig specifies the TLS configuration to use with
	// tls.Client. If nil, the default configuration is used.
	TLSClientConfig *tls.Config

	// QuicConfig is the quic.Config used for dialing new connections.
	// If nil, reasonable default values will be used.
	QuicConfig *quic.Config

	// Dial specifies an optional dial function for creating QUIC
	// connections for requests.
	// If Dial is nil, quic.DialAddr will be used.
	Dial func(network, addr string, tlsCfg *tls.Config, cfg *quic.Config) (quic.Session, error)
	// contains filtered or unexported fields
}

RoundTripper implements the http.RoundTripper interface

func (*RoundTripper) Close

func (r *RoundTripper) Close() error

Close closes the QUIC connections that this RoundTripper has used

func (*RoundTripper) RoundTrip

func (r *RoundTripper) RoundTrip(req *http.Request) (*http.Response, error)

RoundTrip does a round trip.

func (*RoundTripper) RoundTripOpt

func (r *RoundTripper) RoundTripOpt(req *http.Request, opt RoundTripOpt) (*http.Response, error)

RoundTripOpt is like RoundTrip, but takes options.

type Server

type Server struct {
	*http.Server

	// By providing a quic.Config, it is possible to set parameters of the QUIC connection.
	// If nil, it uses reasonable default values.
	QuicConfig *quic.Config

	// Private flag for demo, do not use
	CloseAfterFirstRequest bool
	// contains filtered or unexported fields
}

Server is a HTTP2 server listening for QUIC connections.

func (*Server) Close

func (s *Server) Close() error

Close the server immediately, aborting requests and sending CONNECTION_CLOSE frames to connected clients. Close in combination with ListenAndServe() (instead of Serve()) may race if it is called before a UDP socket is established.

func (*Server) CloseGracefully

func (s *Server) CloseGracefully(timeout time.Duration) error

CloseGracefully shuts down the server gracefully. The server sends a GOAWAY frame first, then waits for either timeout to trigger, or for all running requests to complete. CloseGracefully in combination with ListenAndServe() (instead of Serve()) may race if it is called before a UDP socket is established.

func (*Server) ListenAndServe

func (s *Server) ListenAndServe() error

ListenAndServe listens on the UDP address s.Addr and calls s.Handler to handle HTTP/2 requests on incoming connections.

func (*Server) ListenAndServeTLS

func (s *Server) ListenAndServeTLS(certFile, keyFile string) error

ListenAndServeTLS listens on the UDP address s.Addr and calls s.Handler to handle HTTP/2 requests on incoming connections.

func (*Server) Serve

func (s *Server) Serve(conn net.PacketConn) error

Serve an existing UDP connection.

func (*Server) SetQuicHeaders

func (s *Server) SetQuicHeaders(hdr http.Header) error

SetQuicHeaders can be used to set the proper headers that announce that this server supports QUIC. The values that are set depend on the port information from s.Server.Addr, and currently look like this (if Addr has port 443):

Alt-Svc: quic=":443"; ma=2592000; v="33,32,31,30"
