btcws

[] (https://travis-ci.org/btcsuite/btcws)

Package btcws implements extensions to the standard bitcoind JSON-RPC API for the btcd suite of programs (btcd, btcwallet, and btcgui). Importing this package registers all implemented custom requests with btcjson (using btcjson.RegisterCustomCmd).

Sample Use

// Client Side
import (
	"golang.org/x/net/websocket"
	"github.com/btcsuite/btcws"
)

// Create rescan command.
id := 0
addrs := map[string]struct{}{
	"17XhEvq9Nahdj7Xe1nv6oRe1tEmaHUuynH": struct{},
}
cmd, err := btcws.NewRescanCmd(id, 270000, addrs)

// Set up a handler for a reply with id 0.
AddReplyHandler(id, func(reply map[string]interface{}) {
	// Deal with reply.
})

// JSON marshal and send rescan request to websocket connection.
websocket.JSON.Send(btcdWSConn, cmd)


// Server Side
import (
	"golang.org/x/net/websocket"
	"github.com/btcsuite/btcd/btcjson"
	"github.com/btcsuite/btcws"
)

// Get marshaled request.
var b []byte
err := websocket.Message.Receive(clientWSConn, &b)

// Parse marshaled command.
cmd, err := btcjson.ParseMarshaledCmd(b)

// If this is a rescan command, handle and reply.
rcmd, ok := cmd.(*btcws.RescanCmd)
if ok {
	// Do stuff
	var reply []byte
	err := websocket.Message.Send(clientWSConn, reply)
}
