SDK 初始化
客户端配置
通过实例化 ClientConfig 来完成 SDK 客户端的配置。各参数可按实际开发需求设置。本文档教程所用 Key 通过 KeyStore 导入。
Copy
nodeURI := "tcp://localhost:26657"
network := types.Mainnet
chainID := "irita-test"
gas := 200000
fee := types.NewDecCoins(types.NewDecCoin("point", types.NewInt(5)))
mode := types.Commit
algo := "sm2"
timeout := 10
level := "info"
dbPath := os.Getwd()
clientConfig := types.ClientConfig{
NodeURI: nodeURI,
Network: network,
ChainID: chainID,
Gas: uint64(gas),
Fee: fee,
Mode: mode,
Algo: algo,
KeyDAO: store.NewFileDAO(dbPath),
Timeout: uint(timeout),
Level: level,
}
构建客户端
用生成的 clientConfig 构建客户端。
Copy
client := sdk.NewIRITAClient(clientConfig)
Key 设置
教程使用 KeyStore 导入签名所需 Key。开发者可以通过实现 KeyDAO 接口满足更复杂的业务需求。详见 SDK。
Copy
keyName := "test"
password := "1234567890"
keyStore := `-----BEGIN TENDERMINT PRIVATE KEY-----
kdf: bcrypt
salt: 0DFC160024DC06F28878EC59F1D86C64
type: secp256k1

qC5uVKGBKf6jNGqAx30vkBfIX2pmwa5gKh7Wqhs=
=C5OM
-----END TENDERMINT PRIVATE KEY-----`
_, err := client.Key.Import(keyName, password, keyStore)
if err != nil {
panic(err)
}
