Types

type BatchHTTP 

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

BatchHTTP provides the same interface as `HTTP`, but allows for batching of requests (as per https://www.jsonrpc.org/specification#batch). Do not instantiate directly - rather use the HTTP.NewBatch() method to create an instance of this struct.

Batching of HTTP requests is thread-safe in the sense that multiple goroutines can each create their own batches and send them using the same HTTP client. Multiple goroutines could also enqueue transactions in a single batch, but ordering of transactions in the batch cannot be guaranteed in such an apps.

type HTTP 

type HTTP struct {
	*WSEvents
	// contains filtered or unexported fields
}

HTTP is a Client implementation that communicates with a Tendermint node over JSON RPC and WebSockets.

This is the main implementation you probably want to use in production code. There are other implementations when calling the Tendermint node in-process (Local), or when you want to mock out the server for test code (mock).

You can subscribe for any event published by Tendermint using Subscribe method. Note delivery is best-effort. If you don't read events fast enough or network is slow, Tendermint might cancel the subscription. The client will attempt to resubscribe (you don't need to do anything). It will keep trying every second indefinitely until successful.

Request batching is available for JSON RPC requests over HTTP, which conforms to the JSON RPC specification (https://www.jsonrpc.org/specification#batch). See the apps for more details.

Example: 

c, err := New("http://192.168.1.10:26657", "/websocket")
if err != nil {
	// handle error
}

// call Start/Stop if you're subscribing to events
err = c.Start()
if err != nil {
	// handle error
}
defer c.Stop()

res, err := c.Status()
if err != nil {
	// handle error
}

// handle result

func New 

func New(remote, wsEndpoint string) (*HTTP, error)

WSEvents is a wrapper around WSClient, which implements EventsClient.

func (*WSEvents) OnStart 

func (w *WSEvents) OnStart() error

OnStart implements service.Service by starting WSClient and event loop.

Subscribe implements EventsClient by using WSClient to subscribe given subscriber to query. By default, returns a channel with cap=1. Error is returned if it fails to subscribe.

Channel is never closed to prevent clients from seeing an erroneous event.

It returns an error if WSEvents is not running.

func (*WSEvents) Unsubscribe 

func (w *WSEvents) Unsubscribe(ctx context.Context, subscriber, query string) error

Unsubscribe implements EventsClient by using WSClient to unsubscribe given subscriber from query.

func (w *WSEvents) UnsubscribeAll(ctx context.Context, subscriber string) error

UnsubscribeAll implements EventsClient by using WSClient to unsubscribe given subscriber from all the queries.

It returns an error if WSEvents is not running.
