示例1: sign

func (self *XEth) sign(tx *types.Transaction, from common.Address, didUnlock bool) (*types.Transaction, error) {
	hash := tx.SigHash()
	sig, err := self.doSign(from, hash, didUnlock)
	if err != nil {
		return tx, err
	}
	return tx.WithSignature(sig)
}

示例2: Transact

// Transact forms a transaction from the given arguments and submits it to the
// transactio pool for execution.
func (be *registryAPIBackend) Transact(fromStr, toStr, nonceStr, valueStr, gasStr, gasPriceStr, codeStr string) (string, error) {
	if len(toStr) > 0 && toStr != "0x" && !common.IsHexAddress(toStr) {
		return "", errors.New("invalid address")
	}

	var (
		from             = common.HexToAddress(fromStr)
		to               = common.HexToAddress(toStr)
		value            = common.Big(valueStr)
		gas              *big.Int
		price            *big.Int
		data             []byte
		contractCreation bool
	)

	if len(gasStr) == 0 {
		gas = big.NewInt(90000)
	} else {
		gas = common.Big(gasStr)
	}

	if len(gasPriceStr) == 0 {
		price = big.NewInt(10000000000000)
	} else {
		price = common.Big(gasPriceStr)
	}

	data = common.FromHex(codeStr)
	if len(toStr) == 0 {
		contractCreation = true
	}

	nonce := be.txPool.State().GetNonce(from)
	if len(nonceStr) != 0 {
		nonce = common.Big(nonceStr).Uint64()
	}

	var tx *types.Transaction
	if contractCreation {
		tx = types.NewContractCreation(nonce, value, gas, price, data)
	} else {
		tx = types.NewTransaction(nonce, to, value, gas, price, data)
	}

	acc := accounts.Account{from}
	signature, err := be.am.Sign(acc, tx.SigHash().Bytes())
	if err != nil {
		return "", err
	}
	signedTx, err := tx.WithSignature(signature)
	if err != nil {
		return "", err
	}

	be.txPool.SetLocal(signedTx)
	if err := be.txPool.Add(signedTx); err != nil {
		return "", nil
	}

	if contractCreation {
		addr := crypto.CreateAddress(from, nonce)
		glog.V(logger.Info).Infof("Tx(%s) created: %s\n", signedTx.Hash().Hex(), addr.Hex())
	} else {
		glog.V(logger.Info).Infof("Tx(%s) to: %s\n", signedTx.Hash().Hex(), tx.To().Hex())
	}

	return signedTx.Hash().Hex(), nil
}
