示例1: addTxOuts

func addTxOuts(msgtx *wire.MsgTx, b balance, hash []byte, blockHeight uint32) error {
	anchorHash, err := prependBlockHeight(blockHeight, hash)
	if err != nil {
		anchorLog.Errorf("ScriptBuilder error: %v\n", err)
	}

	builder := txscript.NewScriptBuilder()
	builder.AddOp(txscript.OP_RETURN)
	builder.AddData(anchorHash)

	// latest routine from Conformal btcsuite returns 2 parameters, not 1... not sure what to do for people with the old conformal libraries :(
	opReturn, err := builder.Script()
	msgtx.AddTxOut(wire.NewTxOut(0, opReturn))
	if err != nil {
		anchorLog.Errorf("ScriptBuilder error: %v\n", err)
	}

	amount, _ := btcutil.NewAmount(b.unspentResult.Amount)
	change := amount - fee

	// Check if there are leftover unspent outputs, and return coins back to
	// a new address we own.
	if change > 0 {

		// Spend change.
		pkScript, err := txscript.PayToAddrScript(b.address)
		if err != nil {
			return fmt.Errorf("cannot create txout script: %s", err)
		}
		msgtx.AddTxOut(wire.NewTxOut(int64(change), pkScript))
	}
	return nil
