Overview

Package rpcclient implements a websocket-enabled Bitcoin JSON-RPC client.

Overview

This client provides a robust and easy to use client for interfacing with a Bitcoin RPC server that uses a btcd/bitcoin core compatible Bitcoin JSON-RPC API. This client has been tested with btcd (https://github.com/btcsuite/btcd), btcwallet (https://github.com/btcsuite/btcwallet), and bitcoin core (https://github.com/bitcoin).

In addition to the compatible standard HTTP POST JSON-RPC API, btcd and btcwallet provide a websocket interface that is more efficient than the standard HTTP POST method of accessing RPC. The section below discusses the differences between HTTP POST and websockets.

By default, this client assumes the RPC server supports websockets and has TLS enabled. In practice, this currently means it assumes you are talking to btcd or btcwallet by default. However, configuration options are provided to fall back to HTTP POST and disable TLS to support talking with inferior bitcoin core style RPC servers.

Websockets vs HTTP POST

In HTTP POST-based JSON-RPC, every request creates a new HTTP connection, issues the call, waits for the response, and closes the connection. This adds quite a bit of overhead to every call and lacks flexibility for features such as notifications.

In contrast, the websocket-based JSON-RPC interface provided by btcd and btcwallet only uses a single connection that remains open and allows asynchronous bi-directional communication.

The websocket interface supports all of the same commands as HTTP POST, but they can be invoked without having to go through a connect/disconnect cycle for every call. In addition, the websocket interface provides other nice features such as the ability to register for asynchronous notifications of various events.

Synchronous vs Asynchronous API

The client provides both a synchronous (blocking) and asynchronous API.

The synchronous (blocking) API is typically sufficient for most use cases. It works by issuing the RPC and blocking until the response is received. This allows straightforward code where you have the response as soon as the function returns.

The asynchronous API works on the concept of futures. When you invoke the async version of a command, it will quickly return an instance of a type that promises to provide the result of the RPC at some future time. In the background, the RPC call is issued and the result is stored in the returned instance. Invoking the Receive method on the returned instance will either return the result immediately if it has already arrived, or block until it has. This is useful since it provides the caller with greater control over concurrency.

Notifications

The first important part of notifications is to realize that they will only work when connected via websockets. This should intuitively make sense because HTTP POST mode does not keep a connection open!

All notifications provided by btcd require registration to opt-in. For example, if you want to be notified when funds are received by a set of addresses, you register the addresses via the NotifyReceived (or NotifyReceivedAsync) function.

Notification Handlers

Notifications are exposed by the client through the use of callback handlers which are setup via a NotificationHandlers instance that is specified by the caller when creating the client.

It is important that these notification handlers complete quickly since they are intentionally in the main read loop and will block further reads until they complete. This provides the caller with the flexibility to decide what to do when notifications are coming in faster than they are being handled.

In particular this means issuing a blocking RPC call from a callback handler will cause a deadlock as more server responses won't be read until the callback returns, but the callback would be waiting for a response. Thus, any additional RPCs must be issued an a completely decoupled manner.

Automatic Reconnection

By default, when running in websockets mode, this client will automatically keep trying to reconnect to the RPC server should the connection be lost. There is a back-off in between each connection attempt until it reaches one try per minute. Once a connection is re-established, all previously registered notifications are automatically re-registered and any in-flight commands are re-issued. This means from the caller's perspective, the request simply takes longer to complete.

The caller may invoke the Shutdown method on the client to force the client to cease reconnect attempts and return ErrClientShutdown for all outstanding commands.

The automatic reconnection can be disabled by setting the DisableAutoReconnect flag to true in the connection config when creating the client.

Minor RPC Server Differences and Chain/Wallet Separation

Some of the commands are extensions specific to a particular RPC server. For example, the DebugLevel call is an extension only provided by btcd (and btcwallet passthrough). Therefore if you call one of these commands against an RPC server that doesn't provide them, you will get an unimplemented error from the server. An effort has been made to call out which commmands are extensions in their documentation.

Also, it is important to realize that btcd intentionally separates the wallet functionality into a separate process named btcwallet. This means if you are connected to the btcd RPC server directly, only the RPCs which are related to chain services will be available. Depending on your application, you might only need chain-related RPCs. In contrast, btcwallet provides pass through treatment for chain-related RPCs, so it supports them in addition to wallet-related RPCs.

Errors

There are 3 categories of errors that will be returned throughout this package:

  • Errors related to the client connection such as authentication, endpoint, disconnect, and shutdown
  • Errors that occur before communicating with the remote RPC server such as command creation and marshaling errors or issues talking to the remote server
  • Errors returned from the remote RPC server like unimplemented commands, nonexistent requested blocks and transactions, malformed data, and incorrect networks

The first category of errors are typically one of ErrInvalidAuth, ErrInvalidEndpoint, ErrClientDisconnect, or ErrClientShutdown.

NOTE: The ErrClientDisconnect will not be returned unless the DisableAutoReconnect flag is set since the client automatically handles reconnect by default as previously described.

The second category of errors typically indicates a programmer error and as such the type can vary, but usually will be best handled by simply showing/logging it.

The third category of errors, that is errors returned by the server, can be detected by type asserting the error in a *btcjson.RPCError. For example, to detect if a command is unimplemented by the remote RPC server: 

  amount, err := client.GetBalance("")
  if err != nil {
  	if jerr, ok := err.(*btcjson.RPCError); ok {
  		switch jerr.Code {
  		case btcjson.ErrRPCUnimplemented:
  			// Handle not implemented error

  		// Handle other specific errors you care about
		}
  	}

  	// Log or otherwise handle the error knowing it was not one returned
  	// from the remote RPC server.
  }

Example Usage

The following full-blown client examples are in the examples directory:

  • bitcoincorehttp Connects to a bitcoin core RPC server using HTTP POST mode with TLS disabled and gets the current block count
  • btcdwebsockets Connects to a btcd RPC server using TLS-secured websockets, registers for block connected and block disconnected notifications, and gets the current block count
  • btcwalletwebsockets Connects to a btcwallet RPC server using TLS-secured websockets, registers for notifications about changes to account balances, and gets a list of unspent transaction outputs (utxos) the wallet can sign

NotificationHandlers defines callback function pointers to invoke with notifications. Since all of the functions are nil by default, all notifications are effectively ignored until their handlers are set to a concrete callback.

NOTE: Unless otherwise documented, these handlers must NOT directly call any blocking calls on the client instance since the input reader goroutine blocks until the callback has completed. Doing so will result in a deadlock situation.

type SigHashType 

type SigHashType string

SigHashType enumerates the available signature hashing types that the SignRawTransaction function accepts. 

const (
	// SigHashAll indicates ALL of the outputs should be signed.
	SigHashAll SigHashType = "ALL"

	// SigHashNone indicates NONE of the outputs should be signed.  This
	// can be thought of as specifying the signer does not care where the
	// bitcoins go.
	SigHashNone SigHashType = "NONE"

	// SigHashSingle indicates that a SINGLE output should be signed.  This
	// can be thought of specifying the signer only cares about where ONE of
	// the outputs goes, but not any of the others.
	SigHashSingle SigHashType = "SINGLE"

	// SigHashAllAnyoneCanPay indicates that signer does not care where the
	// other inputs to the transaction come from, so it allows other people
	// to add inputs.  In addition, it uses the SigHashAll signing method
	// for outputs.
	SigHashAllAnyoneCanPay SigHashType = "ALL|ANYONECANPAY"

	// SigHashNoneAnyoneCanPay indicates that signer does not care where the
	// other inputs to the transaction come from, so it allows other people
	// to add inputs.  In addition, it uses the SigHashNone signing method
	// for outputs.
	SigHashNoneAnyoneCanPay SigHashType = "NONE|ANYONECANPAY"

	// SigHashSingleAnyoneCanPay indicates that signer does not care where
	// the other inputs to the transaction come from, so it allows other
	// people to add inputs.  In addition, it uses the SigHashSingle signing
	// method for outputs.
	SigHashSingleAnyoneCanPay SigHashType = "SINGLE|ANYONECANPAY"
)

Constants used to indicate the signature hash type for SignRawTransaction.

func (SigHashType) String
