PlugChain GO SDK makes a simple package of API provided by Plug, which provides great convenience for users to quickly develop applications based on PlugChain.

install

Requirement

Go version above 1.13.5

Use Go Mod

require (
    github.com/oracleNetworkProtocol/plugchain-sdk-go latest
)
replace github.com/gogo/protobuf => github.com/regen-network/protobuf v1.3.3-alpha.regen.1

Usage

Init Client

The initialization SDK code is as follows:

var (
nodeURI string = "tcp://127.0.0.1:26657"
grpcURL string = "127.0.0.1:9090"
chainID string = "chaintest_0-0"
)

options := []types.Option{
types.KeyDAOOption(store.NewMemory(nil)),
types.TimeoutOption(10),
}
cfg, err := types.NewClientConfig(nodeURI, grpcURL, chainID, options...)
if err != nil {
panic(err)
}
client := plugchain_sdk.NewPLUGCHAINClient(cfg)

The ClientConfig component mainly contains the parameters used in the SDK, the specific meaning is shown in the table below

Iterm	Type	Description
NodeURI	string	The RPC address of the PlugChain node connected to the SDK, for example: localhost: 26657
GRPCAddr	string	The GRPC address of the PlugChain node connected to the SDK, for example: localhost: 9090
Network	enum	PlugChain network type, value: Testnet,Mainnet
ChainID	string	ChainID of plugchain, for example: chaintest_0-0
Gas	uint64	The maximum gas to be paid for the transaction, for example: 20000
Fee	DecCoins	Transaction fees to be paid for transactions
KeyDAO	KeyDAO	Private key management interface, If the user does not provide it, the default LevelDB will be used
Mode	enum	Transaction broadcast mode, value: Sync,Async, Commit
StoreType	enum	Private key storage method, value: Keystore,PrivKey
Timeout	time.Duration	Transaction timeout, for example: 5s
LogLevel	string	Log output level, for example: info
Algo	string	Private key generation algorithm(sm2,secp256k1,eth_secp256k1), for example:eth_secp256k1

If you want to use SDK to send a transfer transaction, the example is as follows:

There is more example of query and send tx

//Import keystore
err:= client.Key.Import("username", "passward", string(getPrivKeyArmor()))
baseTx := types.BaseTx{
From:     "username",
Password: "passward",
Gas:      200000,
Mode:     types.Commit,
Memo:     "test",
}
baseTx.Fee, err = types.ParseDecCoins("2000uplugcn")
coins, err := types.ParseDecCoins("100000uplugcn")
to := "gx1akqhezuftdcc0eqzkq5peqpjlucgmyr7srx54j"
result, err := client.Bank.Send(to, coins, baseTx)

query Latest Block info

    block, err := client.BaseClient.Block(context.Background(), nil)

query Tx from specify TxHash

    txHash := "4CBE93F90230B6C1AF324D530858D2087E0D9A6F26DFDAC7842110284AF5728D"
txResult, err := client.BaseClient.QueryTx(txHash)

get TxHash before sending transactions

    //Import keystore
err:= client.Key.Import("username", "passward", string(getPrivKeyArmor()))
baseTx := types.BaseTx{
From:     "username",
Password: "passward",
Gas:      200000,
Mode:     types.Commit,
Memo:     "test",
}
baseTx.Fee, err = types.ParseDecCoins("2000uplugcn")
coins, err := types.ParseCoins("100000uplugcn")
from := "gx1yhf7w0sq8yn6gqre2pulnqwyy30tjfc4v08f3x"
to := "gx1akqhezuftdcc0eqzkq5peqpjlucgmyr7srx54j"
msg := &bank.MsgSend{
FromAddress: from,
ToAddress:   to,
Amount:      coins,
}
txhash, err := client.BuildTxHash([]types.Msg{msg}, baseTx)

Note: If you use the relevant API for sending transactions, you should implement the KeyDAO interface. Use the NewKeyDaoWithAES method to initialize a KeyDAO instance, which will use the AES encryption method by default.
