Functions

func MaxReconnectAttempts added in v0.10.4

func MaxReconnectAttempts(max int) func(*WSClient)

MaxReconnectAttempts sets the maximum number of reconnect attempts before returning an error. It should only be used in the constructor and is not Goroutine-safe.

func OnReconnect added in v0.11.1

func OnReconnect(cb func()) func(*WSClient)

OnReconnect sets the callback, which will be called every time after successful reconnect.

func PingPeriod added in v0.10.4

func PingPeriod(pingPeriod time.Duration) func(*WSClient)

PingPeriod sets the duration for sending websocket pings. It should only be used in the constructor - not Goroutine-safe.

func ReadWait added in v0.10.4

func ReadWait(readWait time.Duration) func(*WSClient)

ReadWait sets the amount of time to wait before a websocket read times out. It should only be used in the constructor and is not Goroutine-safe.

func WriteWait added in v0.10.4

func WriteWait(writeWait time.Duration) func(*WSClient)

WriteWait sets the amount of time to wait before a websocket write times out. It should only be used in the constructor and is not Goroutine-safe.

Types

type HTTPClient

type HTTPClient interface {
	Call(method string, params map[string]interface{}, result interface{}) (interface{}, error)
	Codec() *amino.Codec
	SetCodec(*amino.Codec)
}

HTTPClient is a common interface for JSONRPCClient and URIClient.

type JSONRPCClient

type JSONRPCClient struct {
	// contains filtered or unexported fields
}

JSONRPCClient takes params as a slice

func NewJSONRPCClient

func NewJSONRPCClient(remote string) *JSONRPCClient

NewJSONRPCClient returns a JSONRPCClient pointed at the given address.

func (*JSONRPCClient) Call

func (c *JSONRPCClient) Call(method string, params map[string]interface{}, result interface{}) (interface{}, error)

func (*JSONRPCClient) Codec added in v0.19.0

func (c *JSONRPCClient) Codec() *amino.Codec

func (*JSONRPCClient) SetCodec added in v0.19.0

func (c *JSONRPCClient) SetCodec(cdc *amino.Codec)

type URIClient

type URIClient struct {
	// contains filtered or unexported fields
}

URI takes params as a map

func NewURIClient

func NewURIClient(remote string) *URIClient

func (*URIClient) Call

func (c *URIClient) Call(method string, params map[string]interface{}, result interface{}) (interface{}, error)

func (*URIClient) Codec added in v0.19.0

func (c *URIClient) Codec() *amino.Codec

func (*URIClient) SetCodec added in v0.19.0

func (c *URIClient) SetCodec(cdc *amino.Codec)

type WSClient

type WSClient struct {
	cmn.BaseService

	Address  string // IP:PORT or /path/to/socket
	Endpoint string // /websocket/url/endpoint
	Dialer   func(string, string) (net.Conn, error)

	// Time between sending a ping and receiving a pong. See
	// https://godoc.org/github.com/rcrowley/go-metrics#Timer.
	PingPongLatencyTimer metrics.Timer

	// Single user facing channel to read RPCResponses from, closed only when the client is being stopped.
	ResponsesCh chan types.RPCResponse
	// contains filtered or unexported fields
}

WSClient is a WebSocket client. The methods of WSClient are safe for use by multiple goroutines.

func NewWSClient

func NewWSClient(remoteAddr, endpoint string, options ...func(*WSClient)) *WSClient

NewWSClient returns a new client. See the commentary on the func(*WSClient) functions for a detailed description of how to configure ping period and pong wait time. The endpoint argument must begin with a `/`.

func (*WSClient) Call

func (c *WSClient) Call(ctx context.Context, method string, params map[string]interface{}) error

Call the given method. See Send description.

func (*WSClient) CallWithArrayParams added in v0.10.4

func (c *WSClient) CallWithArrayParams(ctx context.Context, method string, params []interface{}) error

CallWithArrayParams the given method with params in a form of array. See Send description.

func (*WSClient) Codec added in v0.19.0

func (c *WSClient) Codec() *amino.Codec

func (*WSClient) IsActive added in v0.10.4

func (c *WSClient) IsActive() bool

IsActive returns true if the client is running and not reconnecting.

func (*WSClient) IsReconnecting added in v0.10.4

func (c *WSClient) IsReconnecting() bool

IsReconnecting returns true if the client is reconnecting right now.

func (*WSClient) OnStart

func (c *WSClient) OnStart() error

OnStart implements cmn.Service by dialing a server and creating read and write routines.

func (*WSClient) OnStop

func (c *WSClient) OnStop()

OnStop implements cmn.Service.

func (*WSClient) Send added in v0.10.4

func (c *WSClient) Send(ctx context.Context, request types.RPCRequest) error

Send the given RPC request to the server. Results will be available on ResponsesCh, errors, if any, on ErrorsCh. Will block until send succeeds or ctx.Done is closed.

func (*WSClient) SetCodec added in v0.19.0

func (c *WSClient) SetCodec(cdc *amino.Codec)

func (*WSClient) Stop added in v0.10.4

func (c *WSClient) Stop() error

Stop overrides cmn.Service#Stop. There is no other way to wait until Quit channel is closed.

func (*WSClient) String

func (c *WSClient) String() string

String returns WS client full address.
