code out dated about ethereum-development-with-go-book HOT 3 CLOSED

@huahuayu Thanks for the bug report!

Here are some updated examples:

types.Transaction to raw tx hex (using MarshalBinary):

signedTx, err := types.SignTx(tx, types.NewEIP155Signer(chainID), privateKey)
if err != nil {
  log.Fatal(err)
}
rawTxBytes, err := signedTx.MarshalBinary()
if err != nil {
  log.Fatal(err)
}
rawTxHex := hex.EncodeToString(rawTxBytes)
fmt.Println(rawTxHex)

Raw tx hex to type.Transaction (using UnmarshalBinary):

rawTxBytes, err = hex.DecodeString(rawTxHex)
t := types.Transaction{}
err = t.UnmarshalBinary(rawTxBytes)
if err != nil {
  log.Fatal(err)
}

spew.Dump(signedTx)

types.Transaction to raw tx hex (using EncodeRLP):

(this should generate the same tx hex data as the first example)

var buf bytes.Buffer
err = signedTx.EncodeRLP(&buf)
if err != nil {
  log.Fatal(err)
}
rawTxHex := hex.EncodeToString(buf.Bytes())
fmt.Println(rawTxHex)
