func DefaultHTTPClient 

func DefaultHTTPClient(remoteAddr string) (*http.Client, error)

DefaultHTTPClient is used to create an http client with some default parameters. We overwrite the http.Client.Dial so we can do http over tcp or unix. remoteAddr should be fully featured (eg. with tcp:// or unix://). An error will be returned in case of invalid remoteAddr.

func MaxReconnectAttempts 

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 

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

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

func PingPeriod 

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 

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 

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.

type Caller 

type Caller interface {
	Call(method string, params map[string]interface{}, result interface{}) (interface{}, error)
}

Caller implementers can facilitate calling the JSON-RPC endpoint.

type Client 

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

Client is a JSON-RPC client, which sends POST HTTP requests to the remote server.

Request values are amino encoded. Response is expected to be amino encoded. New amino codec is used if no other codec was set using SetCodec.

Client is safe for concurrent use by multiple goroutines.

func New 

func New(remote string) (*Client, error)

New returns a Client pointed at the given address. An error is returned on invalid remote. The function panics when remote is nil.

func NewWithHTTPClient 

func NewWithHTTPClient(remote string, client *http.Client) (*Client, error)

NewWithHTTPClient returns a Client pointed at the given address using a custom http client. An error is returned on invalid remote. The function panics when remote is nil.

func (*Client) Call 

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

Call issues a POST HTTP request. Requests are JSON encoded. Content-Type: text/json.

func (*Client) Codec 

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

func (*Client) NewRequestBatch 

func (c *Client) NewRequestBatch() *RequestBatch

NewRequestBatch starts a batch of requests for this client.

func (*Client) SetCodec

type Cm39HttpJSONClientAdapter 

type Cm39HttpJSONClientAdapter struct {
	*Client
	// contains filtered or unexported fields

type HTTPClient 

type HTTPClient interface {
	// Call calls the given method with the params and returns a result.
	Call(method string, params map[string]interface{}, result interface{}) (interface{}, error)
	// Codec returns an amino codec used.
	Codec() *amino.Codec
	// SetCodec sets an amino codec.
	SetCodec(*amino.Codec)
}

HTTPClient is a common interface for JSON-RPC HTTP clients.

type RequestBatch 

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

RequestBatch allows us to buffer multiple request/response structures into a single batch request. Note that this batch acts like a FIFO queue, and is thread-safe.

func (*RequestBatch) Call 

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

Call enqueues a request to call the given RPC method with the specified parameters, in the same way that the `Client.Call` function would.

func (*RequestBatch) Clear 

func (b *RequestBatch) Clear() int

Clear empties out the request batch.

func (*RequestBatch) Count 

func (b *RequestBatch) Count() int

Count returns the number of enqueued requests waiting to be sent.

func (*RequestBatch) Send 

func (b *RequestBatch) Send() ([]interface{}, error)

Send will attempt to send the current batch of enqueued requests, and then will clear out the requests once done. On success, this returns the deserialized list of results from each of the enqueued requests.

type URIClient 

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

URIClient is a JSON-RPC client, which sends POST form HTTP requests to the remote server.

Request values are amino encoded. Response is expected to be amino encoded. New amino codec is used if no other codec was set using SetCodec.

URIClient is safe for concurrent use by multiple goroutines.

func NewURI 

func NewURI(remote string) (*URIClient, error)

NewURI returns a new client. An error is returned on invalid remote. The function panics when remote is nil.

func (*URIClient) Call 

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

Call issues a POST form HTTP request.

func (*URIClient) Codec 

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

func (*URIClient) SetCodec 

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

type WSClient 

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

	// Single user facing channel to read RPCResponses from, closed only when the
	// client is being stopped.
	ResponsesCh chan types.RPCResponse

	service.BaseService

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

WSClient is a JSON-RPC client, which uses WebSocket for communication with the remote server.

WSClient is safe for concurrent use by multiple goroutines.

func NewWS 

func NewWS(remoteAddr, endpoint string, options ...func(*WSClient)) (*WSClient, error)

NewWS 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 `/`. An error is returned on invalid remote. The function panics when remote is nil.

func (*WSClient) Call 

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

Call enqueues a call request onto the Send queue. Requests are JSON encoded.

func (*WSClient) CallWithArrayParams 

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

CallWithArrayParams enqueues a call request onto the Send queue. Params are in a form of array (e.g. []interface{}{"abcd"}). Requests are JSON encoded.

func (*WSClient) Codec 

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