go-ethereum设置signer

设置代码：

package main

// 签名用的公钥私钥也是采用的owner的公钥私钥

import (
	"fmt"

	"set_signer/triplec"

	"github.com/ethereum/go-ethereum/common"
	"github.com/ethereum/go-ethereum/crypto"
	"github.com/ethereum/go-ethereum/ethclient"
)

const (
	BETA_SERVER_ADDRESS             = "https://data-seed-prebsc-1-s1.bnbchain.org:8545"
	BETA_CONTRACT_ADDRESS           = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
	BETA_CONTRACT_OWNER_PUBLIC_KEY  = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
	BETA_CONTRACT_OWNER_PRIVATE_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
)

func GetConfig() (string, string, string, string) {
	// 默认返回 beta 配置
	return BETA_SERVER_ADDRESS, BETA_CONTRACT_ADDRESS, BETA_CONTRACT_OWNER_PUBLIC_KEY, BETA_CONTRACT_OWNER_PRIVATE_KEY
}

func main() {
	serverAddress, contractAddress, ownerPublicKey, ownerPrivateKey := GetConfig()

	client, _ := ethclient.Dial(serverAddress)
	privateKey, err := crypto.HexToECDSA(ownerPrivateKey)
	if err != nil {
		panic(err)
	}
	auth, err := Author(privateKey, client, 500000, 0)
	medal, err := triplec.NewTriplec(common.HexToAddress(contractAddress), client)

	// 设置signer，为signPrev对应的公钥
	tx, err := medal.SetSinger(auth, common.HexToAddress(ownerPublicKey))
	if err != nil {
		panic("error")
	}
	if tx == nil {
		panic("error")
	}
	hash := tx.Hash().Hex()
	fmt.Printf("setsigner 的hash:%v", hash)
}

结果：

成功与否说明：

有了hash不表示就一定是设置成功了！

设置成功的标志是对应网络的scan能够正常查询到该hash
