Vine (/vaɪn/) 一套简单、高效、可插拔的分布式 RPC 框架。

简介

Vine 基于 go-micro 框架，因此继承了它的优点。并在此基础上增加性能和可用性。

功能

Vine 抽象化分布式系统的内部细节. 以下是主要功能.

动态配置 (Dynamic Config) - 从任意地方加载和热加载动态配置。配置接口提供了一种方法，可以从任何源（如环境变量，文件，etcd）加载应用级别配置。同时支持合并源、甚至定义回退。
数据存储 (Dao) - 一个简单的数据存储接口，用于查询，创建，删除数据记录。内置 memory，file，postgresSQL 等
缓存接口 (Cache) - 支持内部数据缓存，保存临时数据。
服务发现 (Service discovery) - 自动服务注册和名称解析。服务发现是微服务开发的核心功能。当服务A与服务B通讯时，需要知道服务B的IP地址等信息。Vine 内置(mdns)作为服务发现组件，它是零配置系统。
负载均衡 (Load Balancing) - 基于服务发现的客户端负载均衡。当内部存在多个服务实例的地址时，我们需要一种方式确定路由到哪个节点，默认使用随机指定其中一个地址。同时在请求错误时重试不同的节点。
消息编码 (Message Encoding) - 基于Content-Type的动态消息编码。Codec 为客户端和服务端提供 Go 类型的编码和解码，支持各种不同的类型。默认使用 protobuf 和 json。
gRPC 传输 (gRPC transport) - 基于 gRPC 的请求响应，同时支持双向流。Vine 为同步通讯提供一个抽象，使发向服务的请求被自动解析、负载均衡、拨号和流化。
异步消息 (Async Messaging) - 内置订阅发布模型，作为异步通讯和事件驱动架构。事件通知属于微服务开发中的核心模式。默认的消息系统为 HTTP 事件代理。
同步 (Synchronization) - 分布式系统通常以最终一致性的方式构建。内置的 Sync 接口实现分布式锁和领导选举。
可插拔接口 (Pluggable Interfaces) - 得益于 Go 语言的抽象特性。 Vine 为每个模块提供抽象接口，正因为如此，这些接口都是可插拔的。可以在 github.com/vine-io/plugins 查询你需要的插件。

Functions ¶

func NewContext ¶

func NewContext(ctx context.Context, s Service) context.Context

NewContext returns a new Context with the Service embedded within it.

func RegisterHandler ¶

func RegisterHandler(s server.Server, h interface{}, opts ...server.HandlerOption) error

RegisterHandler is syntactic sugar for registering a handler

func RegisterSubscriber ¶

func RegisterSubscriber(topic string, s server.Server, h interface{}, opts ...server.SubscriberOption) error

RegisterSubscriber is syntactic sugar for registering a subscriber

Types ¶

type Context ¶

type Context struct {
	context.Context

	App       *cli.App
	Broker    broker.Broker
	Client    client.Client
	Config    config.Config
	Trace     trace.Tracer
	Dialect   dao.Dialect
	Cache     cache.Cache
	Registry  registry.Registry
	Scheduler gscheduler.Scheduler
}

Context be used when vine service handling request

func InitContext ¶ added in v1.4.2

func InitContext(ctx context.Context) *Context

type Event ¶

type Event interface {
	// Publish publishes a message to the event topic
	Publish(ctx context.Context, msg interface{}, opts ...client.PublishOption) error
}

Event is used to publish messages to topic

type Option ¶

type Option func(*Options)

func Action ¶

func Action(a func(*cli.Context) error) Option

Action can be used to parse user provided cli options

func AfterStart ¶

func AfterStart(fn func() error) Option

AfterStart run functions after service starts

func AfterStop ¶

func AfterStop(fn func() error) Option

AfterStop run functions after service stops

func BeforeStart ¶

func BeforeStart(fn func() error) Option

BeforeStart run functions before service starts

func BeforeStop ¶

func BeforeStop(fn func() error) Option

BeforeStop run functions before service stops

func Cmd ¶

func Cmd(c cmd.Cmd) Option

func HandleSignal ¶

func HandleSignal(b bool) Option

HandleSignal toggle automatic installation of the signal handler that traps TERM, INT, and QUIT. Users of this future to disable the signal handler, should control liveness of the service through the context

func Id ¶

func Id(id string) Option

Id of the service

func Metadata ¶

func Metadata(md map[string]string) Option

Metadata associated with the service

func Name ¶

func Name(n string) Option

Name of the service

func PutContext ¶ added in v1.4.2

func PutContext(ctx context.Context) Option

PutContext specifies a context for the service. Can be used to signal shutdown of the service and for extra option values.

func RegisterInterval ¶

func RegisterInterval(t time.Duration) Option

RegisterInterval specifies the interval on which to re-register

func RegisterTTL ¶

func RegisterTTL(t time.Duration) Option

RegisterTTL specifies the TTL to use when registering the service

func Registry ¶

func Registry(r registry.Registry) Option

Registry sets the registry for the service and the underlying components

func Selector ¶

Selector sets the selector for the service client

func Server ¶

func Server(s server.Server) Option

Server to be used for service

func Tracer ¶

func Tracer(t trace.Tracer) Option

Tracer sets the tracer for the service

func Version ¶

func Version(v string) Option

Version of the service

func WrapCall ¶

func WrapCall(w ...client.CallWrapper) Option

WrapCall is a convenience method for wrapping a Client CallFunc

func WrapClient ¶

func WrapClient(w ...client.Wrapper) Option

WrapClient is a convenience method for wrapping a Client with some middleware component. A list of wrappers can be provided. Wrappers are applied in reverse order so the last is executed first.

func WrapHandler ¶

func WrapHandler(w ...server.HandlerWrapper) Option

WrapHandler adds a handler Wrapper to a list of options passed into the server

func WrapSubscriber ¶

func WrapSubscriber(w ...server.SubscriberWrapper) Option

WrapSubscriber adds subscriber Wrapper to a list of options passed into the server

type Options ¶

type Options struct {
	Broker    broker.Broker
	Cmd       cmd.Cmd
	Client    client.Client
	Config    config.Config
	Server    server.Server
	Trace     trace.Tracer
	Dialect   dao.Dialect
	Cache     cache.Cache
	Registry  registry.Registry
	Scheduler gscheduler.Scheduler

	// Before and After functions
	BeforeStart []func() error
	BeforeStop  []func() error
	AfterStart  []func() error
	AfterStop   []func() error

	// Other options for implementations of the interface
	// can be stored in a context
	Context context.Context

	Signal bool
}

Options for vine service

type Service ¶

type Service interface {
	// Name The service name
	Name() string
	// Init initialises options
	Init(...Option)
	// Options returns the current options
	Options() Options
	// Server is for handling requests and events
	Server() server.Server
	// Client is used to call services
	Client() client.Client
	// Run the service
	Run() error
	// String The service implementation
	String() string
}

Service is an interface that wraps the lower level libraries within vine. It's a convenience method for building and initialising services.
