Documentation

Overview

Introduction

Tendermint supports the following RPC protocols:

* URI over HTTP * JSONRPC over HTTP * JSONRPC over websockets

Tendermint RPC is built using [our own RPC library](https://github.com/AeReach/tendermint/tree/master/rpc/lib). Documentation and tests for that library could be found at `tendermint/rpc/lib` directory.

## Configuration

Set the `laddr` config parameter under `[rpc]` table in the `$TMHOME/config/config.toml` file or the `--rpc.laddr` command-line flag to the desired protocol://host:port setting. Default: `tcp://0.0.0.0:46657`.

## Arguments

Arguments which expect strings or byte arrays may be passed as quoted strings, like `"abc"` or as `0x`-prefixed strings, like `0x616263`.

## URI/HTTP

```bash curl 'localhost:46657/broadcast_tx_sync?tx="abc"' ```

> Response:

```json 

{
	"error": "",
	"result": {
		"hash": "2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF",
		"log": "",
		"data": "",
		"code": 0
	},
	"id": "",
	"jsonrpc": "2.0"
}

```

The first entry in the result-array (`96`) is the method this response correlates with. `96` refers to "ResultTypeBroadcastTx", see [responses.go](https://github.com/AeReach/tendermint/blob/master/rpc/core/types/responses.go) for a complete overview.

## JSONRPC/HTTP

JSONRPC requests can be POST'd to the root RPC endpoint via HTTP (e.g. `http://localhost:46657/`).

```json 

{
	"method": "broadcast_tx_sync",
	"jsonrpc": "2.0",
	"params": [ "abc" ],
	"id": "dontcare"
}

```

## JSONRPC/websockets

JSONRPC requests can be made via websocket. The websocket endpoint is at `/websocket`, e.g. `localhost:46657/websocket`. Asynchronous RPC functions like event `subscribe` and `unsubscribe` are only available via websockets.

## More Examples

See the various bash tests using curl in `test/`, and examples using the `Go` API in `rpc/client/`.

## Get the list

An HTTP Get request to the root RPC endpoint shows a list of available endpoints.

```bash curl 'localhost:46657' ```

> Response:

```plain Available endpoints: /abci_info /dump_consensus_state /genesis /net_info /num_unconfirmed_txs /status /health /unconfirmed_txs /unsafe_flush_mempool /unsafe_stop_cpu_profiler /validators

Endpoints that require arguments: /abci_query?path=_&data=_&prove=_ /block?height=_ /blockchain?minHeight=_&maxHeight=_ /broadcast_tx_async?tx=_ /broadcast_tx_commit?tx=_ /broadcast_tx_sync?tx=_ /commit?height=_ /dial_seeds?seeds=_ /dial_persistent_peers?persistent_peers=_ /subscribe?event=_ /tx?hash=_&prove=_ /unsafe_start_cpu_profiler?filename=_ /unsafe_write_heap_profile?filename=_ /unsubscribe?event=_ ```

func BlockResults 

func BlockResults(heightPtr *int64) (*ctypes.ResultBlockResults, error)

BlockResults gets ABCIResults at a given height. If no height is provided, it will fetch results for the latest block.

Results are for the height of the block containing the txs. Thus response.results[5] is the results of executing getBlock(h).Txs[5]

```shell curl 'localhost:46657/block_results?height=10' ```

```go client := client.NewHTTP("tcp://0.0.0.0:46657", "/websocket") info, err := client.BlockResults(10) ```

  {
   "code": 0,
   "data": "CAFE00F00D"
  },
  {
   "code": 102,
   "data": ""
  }
 ]
}

```

func BlockchainInfo 

func BlockchainInfo(minHeight, maxHeight int64) (*ctypes.ResultBlockchainInfo, error)

Get block headers for minHeight <= height <= maxHeight. Block headers are returned in descending order (highest first).

```shell curl 'localhost:46657/blockchain?minHeight=10&maxHeight=10' ```

```go client := client.NewHTTP("tcp://0.0.0.0:46657", "/websocket") info, err := client.BlockchainInfo(10, 10) ```

func Subscribe 

func Subscribe(wsCtx rpctypes.WSRPCContext, query string) (*ctypes.ResultSubscribe, error)

Subscribe for events via WebSocket.

To tell which events you want, you need to provide a query. query is a string, which has a form: "condition AND condition ..." (no OR at the moment). condition has a form: "key operation operand". key is a string with a restricted set of possible symbols ( \t\n\r\\()"'=>< are not allowed). operation can be "=", "<", "<=", ">", ">=", "CONTAINS". operand can be a string (escaped with single quotes), number, date or time.

Examples: 

tm.event = 'NewBlock'								# new blocks
tm.event = 'CompleteProposal'				# node got a complete proposal
tm.event = 'Tx' AND tx.hash = 'XYZ' # single transaction
tm.event = 'Tx' AND tx.height = 5		# all txs of the fifth block
tx.height = 5												# all txs of the fifth block

Tendermint provides a few predefined keys: tm.event, tx.hash and tx.height. Note for transactions, you can define additional keys by providing tags with DeliverTx response. 

	DeliverTx{
		Tags: []*KVPair{
			"agent.name": "K",
		}
  }

	tm.event = 'Tx' AND agent.name = 'K'
	tm.event = 'Tx' AND account.created_at >= TIME 2013-05-03T14:45:00Z
	tm.event = 'Tx' AND contract.sign_date = DATE 2017-01-01
	tm.event = 'Tx' AND account.owner CONTAINS 'Igor'

See list of all possible events here https://godoc.org/github.com/AeReach/tendermint/types#pkg-constants

For complete query syntax, check out https://godoc.org/github.com/AeReach/tendermint/tmlibs/pubsub/query.

```go import "github.com/AeReach/tendermint/tmlibs/pubsub/query" import "github.com/AeReach/tendermint/types"

client := client.NewHTTP("tcp://0.0.0.0:46657", "/websocket") ctx, cancel := context.WithTimeout(context.Background(), timeout) defer cancel() query := query.MustParse("tm.event = 'Tx' AND tx.height = 3") txs := make(chan interface{}) err := client.Subscribe(ctx, "test-client", query, txs) 

go func() {
  for e := range txs {
    fmt.Println("got ", e.(types.EventDataTx))
	 }
}()
