ISC License

Package btcjson implements concrete types for marshalling to and from the bitcoin JSON-RPC API. A comprehensive suite of tests is provided to ensure proper functionality.

Although this package was primarily written for the btcsuite and adapted to pktd, it has intentionally been designed so it can be used as a standalone package for any projects needing to marshal to and from bitcoin JSON-RPC requests and responses.

Although it's possible to use this package directly to implement an RPC client, it is not recommended since it is only intended as an infrastructure package.

Overview

Package btcjson provides primitives for working with the bitcoin JSON-RPC API.

Overview

When communicating via the JSON-RPC protocol, all of the commands need to be marshalled to and from the the wire in the appropriate format. This package provides data structures and primitives to ease this process.

In addition, it also provides some additional features such as custom command registration, command categorization, and reflection-based help generation.

JSON-RPC Protocol Overview

This information is not necessary in order to use this package, but it does provide some intuition into what the marshalling and unmarshalling that is discussed below is doing under the hood.

As defined by the JSON-RPC spec, there are effectively two forms of messages on the wire:

  • Request Objects {"jsonrpc":"1.0","id":"SOMEID","method":"SOMEMETHOD","params":[SOMEPARAMS]} NOTE: Notifications are the same format except the id field is null.

  • Response Objects {"result":SOMETHING,"error":null,"id":"SOMEID"} {"result":null,"error":{"code":SOMEINT,"message":SOMESTRING},"id":"SOMEID"}

For requests, the params field can vary in what it contains depending on the method (a.k.a. command) being sent. Each parameter can be as simple as an int or a complex structure containing many nested fields. The id field is used to identify a request and will be included in the associated response.

When working with asynchronous transports, such as websockets, spontaneous notifications are also possible. As indicated, they are the same as a request object, except they have the id field set to null. Therefore, servers will ignore requests with the id field set to null, while clients can choose to consume or ignore them.

Unfortunately, the original Bitcoin JSON-RPC API (and hence anything compatible with it) doesn't always follow the spec and will sometimes return an error string in the result field with a null error for certain commands. However, for the most part, the error field will be set as described on failure.

Marshalling and Unmarshalling

Based upon the discussion above, it should be easy to see how the types of this package map into the required parts of the protocol

  • Request Objects (type Request)
  • Commands (type <Foo>Cmd)
  • Notifications (type <Foo>Ntfn)
  • Response Objects (type Response)
  • Result (type <Foo>Result)

To simplify the marshalling of the requests and responses, the MarshalCmd and MarshalResponse functions are provided. They return the raw bytes ready to be sent across the wire.

Unmarshalling a received Request object is a two step process:

  1. Unmarshal the raw bytes into a Request struct instance via json.Unmarshal
  2. Use UnmarshalCmd on the Result field of the unmarshalled Request to create a concrete command or notification instance with all struct fields set accordingly

This approach is used since it provides the caller with access to the additional fields in the request that are not part of the command such as the ID.

Unmarshalling a received Response object is also a two step process:

  1. Unmarhsal the raw bytes into a Response struct instance via json.Unmarshal
  2. Depending on the ID, unmarshal the Result field of the unmarshalled Response to create a concrete type instance

As above, this approach is used since it provides the caller with access to the fields in the response such as the ID and Error.

Command Creation

This package provides two approaches for creating a new command. This first, and preferred, method is to use one of the New<Foo>Cmd functions. This allows static compile-time checking to help ensure the parameters stay in sync with the struct definitions.

The second approach is the NewCmd function which takes a method (command) name and variable arguments. The function includes full checking to ensure the parameters are accurate according to provided method, however these checks are, obviously, run-time which means any mistakes won't be found until the code is actually executed. However, it is quite useful for user-supplied commands that are intentionally dynamic.

Custom Command Registration

The command handling of this package is built around the concept of registered commands. This is true for the wide variety of commands already provided by the package, but it also means caller can easily provide custom commands with all of the same functionality as the built-in commands. Use the RegisterCmd function for this purpose.

A list of all registered methods can be obtained with the RegisteredCmdMethods function.

Command Inspection

All registered commands are registered with flags that identify information such as whether the command applies to a chain server, wallet server, or is a notification along with the method name to use. These flags can be obtained with the MethodUsageFlags flags, and the method can be obtained with the CmdMethod function.

Help Generation

To facilitate providing consistent help to users of the RPC server, this package exposes the GenerateHelp and function which uses reflection on registered commands or notifications, as well as the provided expected result types, to generate the final help text.

In addition, the MethodUsageText function is provided to generate consistent one-line usage for registered commands and notifications using reflection.

Errors

There are 2 distinct type of errors supported by this package:

  • General errors related to marshalling or unmarshalling or improper use of the package (type Error)
  • RPC errors which are intended to be returned across the wire as a part of the JSON-RPC response (type RPCError)

The first category of errors (type Error) typically indicates a programmer error and can be avoided by properly using the API. Errors of this type will be returned from the various functions available in this package. They identify issues such as unsupported field types, attempts to register malformed commands, and attempting to create a new command with an improper number of parameters. The specific reason for the error can be detected by type asserting it to a *btcjson.Error and accessing the ErrorCode field.

The second category of errors (type RPCError), on the other hand, are useful for returning errors to RPC clients. Consequently, they are used in the previously described Response type.

Example (UnmarshalResponse)

This example demonstrates how to unmarshal a JSON-RPC response and then unmarshal the result field in the response to a concrete type. 

// Ordinarily this would be read from the wire, but for this example,
// it is hard coded here for clarity.  This is an example response to a
// getblockheight request.
data := []byte(`{"result":350001,"error":null,"id":1}`)

// Unmarshal the raw bytes from the wire into a JSON-RPC response.
var response btcjson.Response
if err := jsoniter.Unmarshal(data, &response); err != nil {
	fmt.Println("Malformed JSON-RPC response:", err)
	return
}

// Check the response for an error from the server.  For example, the
// server might return an error if an invalid/unknown block hash is
// requested.
if response.Error != nil {
	fmt.Println(response.Error)
	return
}

// Unmarshal the result into the expected type for the response.
var blockHeight int32
if err := jsoniter.Unmarshal(response.Result, &blockHeight); err != nil {
	fmt.Printf("Unexpected result type: %T\n", response.Result)
	return
}
fmt.Println("Block height:", blockHeight)

Output:

Block height: 350001

Functions

func Bool 

func Bool(v bool) *bool

Bool is a helper routine that allocates a new bool value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func CmdMethod 

func CmdMethod(cmd interface{}) (string, er.R)

CmdMethod returns the method for the passed command. The provided command type must be a registered type. All commands provided by this package are registered by default.

func Float64 

func Float64(v float64) *float64

Float64 is a helper routine that allocates a new float64 value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func GenerateHelp 

func GenerateHelp(method string, descs map[string]string, resultTypes ...interface{}) (string, er.R)

GenerateHelp generates and returns help output for the provided method and result types given a map to provide the appropriate keys for the method synopsis, field descriptions, conditions, and result descriptions. The method must be associated with a registered type. All commands provided by this package are registered by default.

The resultTypes must be pointer-to-types which represent the specific types of values the command returns. For example, if the command only returns a boolean value, there should only be a single entry of (*bool)(nil). Note that each type must be a single pointer to the type. Therefore, it is recommended to simply pass a nil pointer cast to the appropriate type as previously shown.

The provided descriptions map must contain all of the keys or an error will be returned which includes the missing key, or the final missing key when there is more than one key missing. The generated help in the case of such an error will use the key in place of the description.

The following outlines the required keys: 

"<method>--synopsis"             Synopsis for the command
"<method>-<lowerfieldname>"      Description for each command argument
"<typename>-<lowerfieldname>"    Description for each object field
"<method>--condition<#>"         Description for each result condition
"<method>--result<#>"            Description for each primitive result num

Notice that the "special" keys synopsis, condition<#>, and result<#> are preceded by a double dash to ensure they don't conflict with field names.

The condition keys are only required when there is more than on result type, and the result key for a given result type is only required if it's not an object.

For example, consider the 'help' command itself. There are two possible returns depending on the provided parameters. So, the help would be generated by calling the function as follows: 

GenerateHelp("help", descs, (*string)(nil), (*string)(nil)).

The following keys would then be required in the provided descriptions map: 

"help--synopsis":   "Returns a list of all commands or help for ...."
"help-command":     "The command to retrieve help for",
"help--condition0": "no command provided"
"help--condition1": "command specified"
"help--result0":    "List of commands"
"help--result1":    "Help for specified command"

func Int 

func Int(v int) *int

Int is a helper routine that allocates a new int value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func Int32 

func Int32(v int32) *int32

Int32 is a helper routine that allocates a new int32 value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func Int64 

func Int64(v int64) *int64

Int64 is a helper routine that allocates a new int64 value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func IsValidIDType 

func IsValidIDType(id interface{}) bool

IsValidIDType checks that the ID field (which can go in any of the JSON-RPC requests, responses, or notifications) is valid. JSON-RPC 1.0 allows any valid JSON type. JSON-RPC 2.0 (which bitcoind follows for some parts) only allows string, number, or null, so this function restricts the allowed types to that list. This function is only provided in case the caller is manually marshalling for some reason. The functions which accept an ID in this package already call this function to ensure the provided id is valid.

func MarshalCmd 

func MarshalCmd(id interface{}, cmd interface{}) ([]byte, er.R)

MarshalCmd marshals the passed command to a JSON-RPC request byte slice that is suitable for transmission to an RPC server. The provided command type must be a registered type. All commands provided by this package are registered by default.

Example

This example demonstrates how to create and marshal a command into a JSON-RPC request. 

package main

import (
	"fmt"

	"github.com/pkt-cash/pktd/btcjson"
)

func main() {
	// Create a new getblock command.  Notice the nil parameter indicates
	// to use the default parameter for that fields.  This is a common
	// pattern used in all of the New<Foo>Cmd functions in this package for
	// optional fields.  Also, notice the call to btcjson.Bool which is a
	// convenience function for creating a pointer out of a primitive for
	// optional parameters.
	blockHash := "000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f"
	gbCmd := btcjson.NewGetBlockCmd(blockHash, btcjson.Bool(false), nil)

	// Marshal the command to the format suitable for sending to the RPC
	// server.  Typically the client would increment the id here which is
	// request so the response can be identified.
	id := 1
	marshalledBytes, err := btcjson.MarshalCmd(id, gbCmd)
	if err != nil {
		fmt.Println(err)
		return
	}

	// Display the marshalled command.  Ordinarily this would be sent across
	// the wire to the RPC server, but for this example, just display it.
	fmt.Printf("%s\n", marshalledBytes)

}

Output:

{"jsonrpc":"1.0","method":"getblock","params":["000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f",false],"id":1}

func MarshalResponse 

func MarshalResponse(id interface{}, result interface{}, rpcErr er.R) ([]byte, er.R)

MarshalResponse marshals the passed id, result, and RPCError to a JSON-RPC response byte slice that is suitable for transmission to a JSON-RPC client.

Example

This example demonstrates how to marshal a JSON-RPC response. 

package main

import (
	"fmt"

	"github.com/pkt-cash/pktd/btcjson"
)

func main() {
	// Marshal a new JSON-RPC response.  For example, this is a response
	// to a getblockheight request.
	marshalledBytes, err := btcjson.MarshalResponse(1, 350001, nil)
	if err != nil {
		fmt.Println(err)
		return
	}

	// Display the marshalled response.  Ordinarily this would be sent
	// across the wire to the RPC client, but for this example, just display
	// it.
	fmt.Printf("%s\n", marshalledBytes)

}

Output:

{"result":350001,"error":null,"id":1}

func MethodUsageText 

func MethodUsageText(method string) (string, er.R)

MethodUsageText returns a one-line usage string for the provided method. The provided method must be associated with a registered type. All commands provided by this package are registered by default.

func MustRegisterCmd 

func MustRegisterCmd(method string, cmd interface{}, flags UsageFlag)

MustRegisterCmd performs the same function as RegisterCmd except it panics if there is an error. This should only be called from package init functions.

func NewCmd 

func NewCmd(method string, args ...interface{}) (interface{}, er.R)

NewCmd provides a generic mechanism to create a new command that can marshal to a JSON-RPC request while respecting the requirements of the provided method. The method must have been registered with the package already along with its type definition. All methods associated with the commands exported by this package are already registered by default.

The arguments are most efficient when they are the exact same type as the underlying field in the command struct associated with the the method, however this function also will perform a variety of conversions to make it more flexible. This allows, for example, command line args which are strings to be passed unaltered. In particular, the following conversions are supported:

  • Conversion between any size signed or unsigned integer so long as the value does not overflow the destination type
  • Conversion between float32 and float64 so long as the value does not overflow the destination type
  • Conversion from string to boolean for everything strconv.ParseBool recognizes
  • Conversion from string to any size integer for everything strconv.ParseInt and strconv.ParseUint recognizes
  • Conversion from string to any size float for everything strconv.ParseFloat recognizes
  • Conversion from string to arrays, slices, structs, and maps by treating the string as marshalled JSON and calling jsoniter.Unmarshal into the destination field

func NewErrRPCInternal 

func NewErrRPCInternal() er.R

func NewRPCError 

func NewRPCError(code *er.ErrorCode, message string, err er.R) er.R

NewRPCError constructs and returns a new JSON-RPC error that is suitable for use in a JSON-RPC Response object.

func RegisterCmd 

func RegisterCmd(method string, cmd interface{}, flags UsageFlag) er.R

RegisterCmd registers a new command that will automatically marshal to and from JSON-RPC with full type checking and positional parameter support. It also accepts usage flags which identify the circumstances under which the command can be used.

This package automatically registers all of the exported commands by default using this function, however it is also exported so callers can easily register custom types.

The type format is very strict since it needs to be able to automatically marshal to and from JSON-RPC 1.0. The following enumerates the requirements:

  • The provided command must be a single pointer to a struct
  • All fields must be exported
  • The order of the positional parameters in the marshalled JSON will be in the same order as declared in the struct definition
  • Struct embedding is not supported
  • Struct fields may NOT be channels, functions, complex, or interface
  • A field in the provided struct with a pointer is treated as optional
  • Multiple indirections (i.e **int) are not supported
  • Once the first optional field (pointer) is encountered, the remaining fields must also be optional fields (pointers) as required by positional params
  • A field that has a 'jsonrpcdefault' struct tag must be an optional field (pointer)

NOTE: This function only needs to be able to examine the structure of the passed struct, so it does not need to be an actual instance. Therefore, it is recommended to simply pass a nil pointer cast to the appropriate type. For example, (*FooCmd)(nil).

func RegisteredCmdMethods 

func RegisteredCmdMethods() []string

RegisteredCmdMethods returns a sorted list of methods for all registered commands.

func String 

func String(v string) *string

String is a helper routine that allocates a new string value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func Uint 

func Uint(v uint) *uint

Uint is a helper routine that allocates a new uint value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func Uint32 

func Uint32(v uint32) *uint32

Uint32 is a helper routine that allocates a new uint32 value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func Uint64 

func Uint64(v uint64) *uint64

Uint64 is a helper routine that allocates a new uint64 value to store v and returns a pointer to it. This is useful when assigning optional parameters.

func UnmarshalCmd 

func UnmarshalCmd(r *Request) (interface{}, er.R)

UnmarshalCmd unmarshals a JSON-RPC request into a suitable concrete command so long as the method type contained within the marshalled request is registered.

Example

This example demonstrates how to unmarshal a JSON-RPC request and then unmarshal the concrete request into a concrete command. 

// Ordinarily this would be read from the wire, but for this example,
// it is hard coded here for clarity.
data := []byte(`{"jsonrpc":"1.0","method":"getblock","params":["000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f",false],"id":1}`)

// Unmarshal the raw bytes from the wire into a JSON-RPC request.
var request btcjson.Request
if err := jsoniter.Unmarshal(data, &request); err != nil {
	fmt.Println(err)
	return
}

// Typically there isn't any need to examine the request fields directly
// like this as the caller already knows what response to expect based
// on the command it sent.  However, this is done here to demonstrate
// why the unmarshal process is two steps.
if request.ID == nil {
	fmt.Println("Unexpected notification")
	return
}
if request.Method != "getblock" {
	fmt.Println("Unexpected method")
	return
}

// Unmarshal the request into a concrete command.
cmd, err := btcjson.UnmarshalCmd(&request)
if err != nil {
	fmt.Println(err)
	return
