Documentation

Overview

Package http implements the HTTP inbound and outbound transports for YARPC.

Note that the Close method for the HTTP Inbound does NOT immediately close the ongoing connections. The connection will remain open until all clients have disconnected.

Functions

func NewOutbound

func NewOutbound(url string, opts ...OutboundOption) transport.Outbound

NewOutbound builds a new HTTP outbound that sends requests to the given URL.

Types

type Inbound

type Inbound interface {
	transport.Inbound

	// Address on which the server is listening. Returns nil if Start has not
	// been called yet.
	Addr() net.Addr
}

Inbound represents an HTTP Inbound. It is the same as the transport Inbound except it exposes the address on which the system is listening for connections.

func NewInbound

func NewInbound(addr string, opts ...InboundOption) Inbound

NewInbound builds a new HTTP inbound that listens on the given address.

type InboundOption

type InboundOption func(*inbound)

InboundOption is an option for an HTTP inbound.

func Mux

func Mux(pattern string, mux *http.ServeMux) InboundOption

Mux specifies the ServeMux that the HTTP server should use and the pattern under which the YARPC endpoint should be registered.

type OutboundOption

type OutboundOption func(*outboundConfig)

OutboundOption customizes the behavior of an HTTP outbound.

func KeepAlive

func KeepAlive(t time.Duration) OutboundOption

KeepAlive specifies the keep-alive period for the network connection. If zero, keep-alives are disabled.

Defaults to 30 seconds.
