Types

type Endpointer

type Endpointer interface {
	Endpoint() (*url.URL, error)
}

Endpointer is registry endpoint.

type Header

type Header interface {
	Get(key string) string
	Set(key string, value string)
	Add(key string, value string)
	Keys() []string
	Values(key string) []string
}

type Kind

type Kind string

Kind defines the type of Transport

const (
	KindGRPC Kind = "grpc"
	KindHTTP Kind = "http"
	KindTCP  Kind = "tcp"
)

Defines a set of transport kind

func (Kind) String

func (k Kind) String() string

type Server

type Server interface {
	Start(context.Context) error
	Stop(context.Context) error
}

Server is transport server.

type Transporter

type Transporter interface {
	// Kind transporter
	// grpc
	// http
	// tcp
	Kind() Kind
	// Endpoint return server or client endpoint
	// Server Transport: grpc://127.0.0.1:9000
	// Client Transport: discovery:///provider-demo
	Endpoint() string
	// Operation Service full method selector generated by protobuf
	// example: /helloworld.Greeter/SayHello
	Operation() string // grpc method or http path  , tcp 为空
	// RequestHeader return transport request header
	// http: http.Header
	// grpc: metadata.MD
	RequestHeader() Header //tcp没有
	// ReplyHeader return transport reply/response header
	// only valid for server transport
	// http: http.Header
	// grpc: metadata.MD
	ReplyHeader() Header //tcp没有
}

Transporter is transport context value interface.
