gosdk 的 ont|ong.transfer 怎么设置 payer?

[straysh]

假设: a 向 b 转账 1 ONT，通常是a地址扣除1ONT,0.01ONG, b地址收到1ONT 看见java sdk中可以设置 gas 的扣费地址，是不是说 可以设置为 0.01ONG由 C 地址扣除

gosdk中, MutableTransaction 也可以设置Payer

type MutableTransaction struct {
    Version  byte
    TxType   TransactionType
    Nonce    uint32
    GasPrice uint64
    GasLimit uint64
    Payer    common.Address
    Payload  Payload
    //Attributes []*TxAttribute
    attributes byte //this must be 0 now, Attribute Array length use VarUint encoding, so byte is enough for extension
    Sigs       []Sig
}

那么怎么构造这样的交易呢？

[straysh]

// 设置 payer
ont := ontcore.OntSdk.Native.Ont
tx, err := ont.NewTransferTransaction(gasPrice, gasLimit, from.Address, to, amount);if err!=nil {panic(err)}
err = ontcore.OntSdk.SignToTransaction(tx, payer);if err!=nil {panic(err)}
err = ontcore.OntSdk.SignToTransaction(tx, from);if err!=nil {panic(err)}
txhash,err := ontcore.OntSdk.SendTransaction(tx);if err!=nil {panic(err)}

事实上，用payer再签名一次就可以了。
