Go API is a pluggable API framework driven by service discovery to help build powerful public API gateways.

Overview

The Go API library provides api gateway routing capabilities. A microservice architecture decouples application logic into separate service. An api gateway provides a single entry point to consolidate these services into a unified api. The Go API uses routes defined in service discovery metadata to generate routing rules and serve http requests.

Go API

Go API is the basis for the micro api.

Functions

func Encode

func Encode(e *Endpoint) map[string]string

Encode encodes an endpoint to endpoint metadata

func Validate

func Validate(e *Endpoint) error

Validate validates an endpoint to guarantee it won't blow up when being served

func WithEndpoint

func WithEndpoint(e *Endpoint) server.HandlerOption

WithEndpoint returns a server.HandlerOption with endpoint metadata set

Usage:

proto.RegisterHandler(service.Server(), new(Handler), api.WithEndpoint(
	&api.Endpoint{
		Name: "Greeter.Hello",
		Path: []string{"/greeter"},
	},
))

Types

type Endpoint

type Endpoint struct {
	// RPC Method e.g. Greeter.Hello
	Name string
	// Description e.g what's this endpoint for
	Description string
	// API Handler e.g rpc, proxy
	Handler string
	// HTTP Host e.g example.com
	Host []string
	// HTTP Methods e.g GET, POST
	Method []string
	// HTTP Path e.g /greeter. Expect POSIX regex
	Path []string
}

Endpoint is a mapping between an RPC method and HTTP endpoint

func Decode

func Decode(e map[string]string) *Endpoint

Decode decodes endpoint metadata into an endpoint

type Service

type Service struct {
	// Name of service
	Name string
	// The endpoint for this service
	Endpoint *Endpoint
	// Versions of this service
	Services []*registry.Service
}

Service represents an API service
