以太坊错误 {"code":-32000,"message":"帐户未知"}

在使用 `eth.sendtransaction` 发送原始交易时，遇到了 "帐户未知" 错误。代码调用 `eth_sendTransaction` 方法，但收到了 {"code":-32000,"message":"unknown account"} 错误消息。该错误表明交易中指定的帐户不存在或无效。需要确定帐户不存在的原因，并采取适当的措施来解决问题。

我尝试使用 eth.sendtransaction 发送原始交易，但收到一条错误消息，提示 {"code":-32000,"message":"unknown account"}。我不确定是什么原因造成的，而且我似乎无法在互联网上找到答案。谁能帮我弄清楚吗？这是我的代码：

func ExecuteSignedTransaction(rawTransaction string) {
    var hash web3.Hash
    data := make(map[string]interface{})
    data["data"] = rawTransaction
    err := Web3HTTPClient.Call("eth_sendTransaction", &hash, data)

    if err != nil{
        fmt.Println(err)
        Os.Exit(1)
     }

    fmt.Println("Sent tx hash:", hash)
}

正确答案

那么，我在这里可能做什么：

import (
  "strings"
  "crypto/ecdsa"
  "math/big"
  "github.com/ethereum/go-ethereum/ethclient"
  "github.com/ethereum/go-ethereum/crypto"
  "github.com/ethereum/go-ethereum/accounts/abi/bind"
)

var chainId = big.NewInt(1) // chain id for the ethereum mainnet, change according to needs

func ecdsaPrivateKeyFromHex(privKeyHex string) *ecdsa.PrivateKey {
  ecdsaKey, err := crypto.HexToECDSA(privKeyHex)
  if err != nil { panic(err) }

  return ecdsaKey
}

func newTransactOpts(privKey *ecdsa.PrivateKey) *bind.TransactOpts {
  transactOpts, err := bind.NewKeyedTransactorWithChainID(privKey, chainId)
  if err != nil { panic(err) }

  return transactOpts
}

func newRpcClient() *ethclient.Client {
  c, err := ethclient.Dial("insert rpc url here")
  if err != nil { panic(err) }
  
  return c
}

// note: constructing the *types.Transaction object left as 
// an exercise to the reader
func ExecuteTransaction(rawTransaction *types.Transaction) {
  privKeyHex := "0xblahblahblahblahblah" // use your own account's private key
  transactOpts := newTransactOpts(ecdsaPrivateKeyFromHex(privKeyHex))

  signedTxn, err := transactOpts.Signer(transactOpts.From, rawTransaction)
  if err != nil { panic(err) }
  
  rpcClient := newRpcClient()
  if err := rpcClient.SendTransaction(context.Background(), signedTxn); err != nil { panic(err) }

  // do whatever
}
