Functions

func NewHttp2Conn

func NewHttp2Conn(c net.Conn, pipedReqBody *io.PipeWriter, respBody io.ReadCloser) net.Conn

Types

type ContextKeyHeader

type ContextKeyHeader struct{}

Users of context.WithValue should define their own types for keys

type HTTPConnectDialer

type HTTPConnectDialer struct {
	ProxyUrl      url.URL
	DefaultHeader http.Header

	// TODO: If spkiFp is set, use it as SPKI fingerprint to confirm identity of the
	// proxy, instead of relying on standard PKI CA roots
	SpkiFP []byte

	Dialer net.Dialer // overridden dialer allow to control establishment of TCP connection

	// overridden DialTLS allows user to control establishment of TLS connection
	// MUST return connection with completed Handshake, and NegotiatedProtocol
	DialTLS func(network string, address string) (net.Conn, string, error)

	EnableH2ConnReuse bool
	// contains filtered or unexported fields
}

HTTPConnectDialer allows to configure one-time use HTTP CONNECT client

func NewHTTPConnectDialer

func NewHTTPConnectDialer(proxyUrlStr string) (*HTTPConnectDialer, error)

NewHTTPClient creates a client to issue CONNECT requests and tunnel traffic via HTTPS proxy. proxyUrlStr must provide Scheme and Host, may provide credentials and port. Example: https://username:password@golang.org:443

func (*HTTPConnectDialer) Dial

func (c *HTTPConnectDialer) Dial(network, address string) (net.Conn, error)

func (*HTTPConnectDialer) DialContext

func (c *HTTPConnectDialer) DialContext(ctx context.Context, network, address string) (net.Conn, error)

ctx.Value will be inspected for optional ContextKeyHeader{} key, with `http.Header` value, which will be added to outgoing request headers, overriding any colliding c.DefaultHeader
