TRON js签名交易

trc20:

var contractAddress = "TRC-20 合约";
//选择合约方法
let functionSelector = "transfer(address,uint256)"; 
  //根据方法构造参数
let parameter = [
    {type: "address",value: address},
    { type: "uint256", value: Math.ceil(number) }
];
//额外参数
let options = {
     shouldPollResponse: false,
     feeLimit: 1000000 //1Trx
};
// 构造智能合约交易信息
let res = await tronWeb.transactionBuilder
  .triggerSmartContract(contractAddress, functionSelector, options, parameter)
    .catch(err1 => {
     // 构建交易信息失败
      return false;
    });
// 向转账交易信息中追加 备注信息 
await tronWeb.transactionBuilder.addUpdateData(res.transaction, "备注信息", 'utf8');
// 对已经添加备注的交易信息进行签名
let sign = await tronWeb.trx.sign(res.transaction).catch(err2 => {
    //签名失败
    return false;
});
// 将签名交易广播上链
return await tronWeb.trx.sendRawTransaction(sign).catch(outputErr => {
    //交易广播出错
    console.log(outputErr);
    return false;
});
