var (
	MessageTypeText = &MessageType{
		Config: nil,
		value:  websocket.TextMessage,
	}

	MessageTypeBinary = &MessageType{
		Config: nil,
		value:  websocket.BinaryMessage,

var IsWebSocketUpgrade func(r *http.Request) bool = websocket.IsWebSocketUpgrade

IsWebSocketUpgrade 是否是WebSocket请求？

Functions

func DefaultUpgrader

func DefaultUpgrader() *websocket.Upgrader

DefaultUpgrader 默认的Upgrader.

@return 并发安全的

func NewProcessor

func NewProcessor(upgrader *websocket.Upgrader, idGenerator func() (string, error), listener pushKit.Listener, messageType *MessageType, pongInterval time.Duration) (pushKit.Processor, error)

NewProcessor

!!!: 需要先调用 pushKit.MustSetUp 或 pushKit.SetUp.

@param upgrader 可以为nil（将使用默认的） @param idGenerator 可以为nil（将使用xid） @param listener 不能为nil @param msgType 消息类型 @param pongInterval pong的周期（<=0则不发送pong）

func PolyfillWebSocketRequest

func PolyfillWebSocketRequest(r *http.Request)

PolyfillWebSocketRequest

此函数是为了避免情况: 代理（e.g.Nginx）没有设置WebSocket穿透，导致WebSocket服务收到的WebSocket请求的header有问题.

Types

type MessageType

type MessageType struct {
	*gzipKit.Config
	// contains filtered or unexported fields
}

func NewGzipMessageType

func NewGzipMessageType(level, compressThreshold int) (*MessageType, error)

NewGzipMessageType

PS: 此种情况下，必定使用 websocket.BinaryMessage.

type WsChannel

type WsChannel struct {
	pushKit.BaseChannel
	// contains filtered or unexported fields
}

func (*WsChannel) BindBsid

func (channel *WsChannel) BindBsid(bsid string)

func (*WsChannel) BindGroup

func (channel *WsChannel) BindGroup(group string)

func (*WsChannel) BindUser

func (channel *WsChannel) BindUser(user string)

func (*WsChannel) Close

func (channel *WsChannel) Close(reason string) (err error)

Close 后端主动关闭通道.

func (*WsChannel) Dispose

func (channel *WsChannel) Dispose()

Dispose 仅是释放资源，不会关闭通道（应当先关闭通道，再释放资源）.

func (*WsChannel) Initialize

func (channel *WsChannel) Initialize() error

func (*WsChannel) Push

func (channel *WsChannel) Push(data []byte) error

func (*WsChannel) PushMessage

func (channel *WsChannel) PushMessage(messageType *MessageType, data []byte) (err error)

PushMessage 推送消息给客户端.

@param MessageType MessageTypeText || MessageTypeBinary
