Documentation

Overview

Package core provides an entry point to use V2Ray core functionalities.

V2Ray makes it possible to accept incoming network connections with certain protocol, process the data, and send them through another connection with the same or a difference protocol on demand.

It may be configured to work with multiple protocols at the same time, and uses the internal router to tunnel through different inbound and outbound connections.

Functions

func AddInboundHandler

func AddInboundHandler(server *Instance, config *InboundHandlerConfig) error

func AddOutboundHandler

func AddOutboundHandler(server *Instance, config *OutboundHandlerConfig) error

func CreateObject

func CreateObject(v *Instance, config interface{}) (interface{}, error)

CreateObject creates a new object based on the given V2Ray instance and config. The V2Ray instance may be nil.

func Dial

func Dial(ctx context.Context, v *Instance, dest net.Destination) (net.Conn, error)

Dial provides an easy way for upstream caller to create net.Conn through V2Ray. It dispatches the request to the given destination by the given V2Ray instance. Since it is under a proxy context, the LocalAddr() and RemoteAddr() in returned net.Conn will not show real addresses being used for communication.

v2ray:api:stable

func DialUDP

func DialUDP(ctx context.Context, v *Instance) (net.PacketConn, error)

DialUDP provides a way to exchange UDP packets through V2Ray instance to remote servers. Since it is under a proxy context, the LocalAddr() in returned PacketConn will not show the real address.

TODO: SetDeadline() / SetReadDeadline() / SetWriteDeadline() are not implemented.

v2ray:api:beta

func RegisterConfigLoader

func RegisterConfigLoader(format *ConfigFormat) error

RegisterConfigLoader add a new ConfigLoader.

func RequireFeatures

func RequireFeatures(ctx context.Context, callback interface{}) error

RequireFeatures is a helper function to require features from Instance in context. See Instance.RequireFeatures for more information.

func ServerType

func ServerType() interface{}

ServerType returns the type of the server.

func Version

func Version() string

Version returns V2Ray's version as a string, in the form of "x.y.z" where x, y and z are numbers. ".z" part may be omitted in regular releases.

func VersionStatement

func VersionStatement() []string

VersionStatement returns a list of strings representing the full version info.

Types

type Annotation

type Annotation struct {
	// API is for types or functions that can be used in other libs. Possible values are:
	//
	// * v2ray:api:beta for types or functions that are ready for use, but maybe changed in the future.
	// * v2ray:api:stable for types or functions with guarantee of backward compatibility.
	// * v2ray:api:deprecated for types or functions that should not be used anymore.
	//
	// Types or functions without api annotation should not be used externally.
	API string
}

Annotation is a concept in V2Ray. This struct is only for documentation. It is not used anywhere. Annotations begin with "v2ray:" in comment, as metadata of functions or types.

type Config

	// Inbound handler configurations. Must have at least one item.
	Inbound []*InboundHandlerConfig `protobuf:"bytes,1,rep,name=inbound,proto3" json:"inbound,omitempty"`
	// Outbound handler configurations. Must have at least one item. The first item is used as default for routing.
	Outbound []*OutboundHandlerConfig `protobuf:"bytes,2,rep,name=outbound,proto3" json:"outbound,omitempty"`
	// App is for configurations of all features in V2Ray. A feature must implement the Feature interface, and its config type must be registered through common.RegisterConfig.
	App []*serial.TypedMessage `protobuf:"bytes,4,rep,name=app,proto3" json:"app,omitempty"`
	// Transport settings.
	// Deprecated. Each inbound and outbound should choose their own transport config.

	Transport *transport.Config `protobuf:"bytes,5,opt,name=transport,proto3" json:"transport,omitempty"` // Deprecated: Do not use.
	// Configuration for extensions. The config may not work if corresponding extension is not loaded into V2Ray.
