EOS.IO API library for Go

点击查看中文版

GoDoc

This library provides simple access to data structures (binary packing and JSON interface) and API calls to an EOS.IO RPC server, running remotely or locally. It provides wallet functionalities (KeyBag), or can sign transaction through the keosd wallet. It also knows about the P2P protocol on port 9876.

As of before the June launch, this library is pretty much in flux. Don't expect stability, as we're moving alongside the main eosio codebase, which changes very fast.

This library is the basis for the eos-bios launch orchestrator tool at https://github.com/eoscanada/eos-bios

Basic usage

api := eos.New("http://testnet1.eos.io")

infoResp, _ := api.GetInfo()
accountResp, _ := api.GetAccount("initn")
fmt.Println("Permission for initn:", accountResp.Permissions[0].RequiredAuth.Keys)

eosio.system and eosio.token contract Actions are respectively in:

Binaries

There is some binaries in main packages under cmd/, mainly around P2P communication.

Example

Reference
Running

The easiest way to see the actual output for a given example is to add a line // Output: any at the very end of the test, looks like this for ExampleAPI_GetInfo file (examples_api_get_info.go):

    if err != nil {
        panic(fmt.Errorf("json marshal response: %s", err))
    }

    fmt.Println(string(bytes))
    // Output: any
}

This tells go test that it can execute this test correctly. Then, simply run only this example:

go test -run ExampleAPI_GetInfo

Replacing ExampleAPI_GetInfo with the actual example name you want to try out where line // Output: any was added.

This will run the example and compares the standard output with the any which will fail. But it's ok an expected, so you can see the actual output printed to your terminal.

Note Some examples will not succeed out of the box because it requires some configuration. A good example being the transfer operation which requires having the authorizations and balance necessary to perform the transaction. It's quite possible to run them through a development environment however.

Environment Variables

All examples uses by default the https://mainnet.eos.dfuse.io API endpoint for all HTTP communication and peering.mainnet.eoscanada.com for P2P communication. They can respectively be overridden by specifying environment variable EOS_GO_API_URL and EOS_GO_P2P_ENDPOINT respectively.

Functions

func BlockNum 

func BlockNum(blockID string) uint32

BlockNum extracts the block number (or height) from a hex-encoded block ID.

func EnableABIDecoderLogging

func ExtendedStringToName added in v0.8.10 

func ExtendedStringToName(s string) (val uint64, err error)

ExtendedStringToName acts similar to StringToName with the big differences that it will automtically try to infer from which format to convert to a name. Current rules are: - If the `s` contains a `,` character, assumes it's a `Symbol` - If the `s` contains only upper-case characters and length is <= 7, assumes it's a `SymbolCode` - Otherwise, forwards `s` to `StringToName` directly

func MarshalBinary 

func MarshalBinary(v interface{}) ([]byte, error)

func NameToString

func (*API) SignTransaction 

func (api *API) SignTransaction(tx *Transaction, chainID Checksum256, compression CompressionType) (*SignedTransaction, *PackedTransaction, error)

SignTransaction will sign and pack a transaction, but not submit to the chain. It lives on the `api` object because it might query the blockchain to learn which keys are required to sign this particular transaction.

You can override the way we request keys (which defaults to `api.GetRequiredKeys()`) with SetCustomGetRequiredKeys().

To sign a transaction, you need a Signer defined on the `API` object. See SetSigner.

func (APIError) Error 

func (e APIError) Error() string

func (APIError) IsUnknownKeyError added in v0.8.6 

func (e APIError) IsUnknownKeyError() bool

IsUnknowKeyError determines if the APIError is a 500 error with an `unknown key` message in at least one of the detail element. Some endpoint like `/v1/chain/get_account` returns a body in the form:

``` 

 {
 	"code": 500,
 	"message": "Internal Service Error",
 	"error": {
 		"code": 0,
 		"name": "exception",
 		"what": "unspecified",
 		"details": [
		 		{
		 			"message": "unknown key (<... redacted ...>): (0 eos.rex)",
		 			"file": "http_plugin.cpp",
		 			"line_number": 589,
		 			"method": "handle_exception"
		 		}
 		]
 	}
 }

```

This will check if root code is a 500, that inner error code is 0 and there is a detail message starting with prefix `"unknown key"`.
