如何获取波场智能合约的balanceOf

Question

我正在使用 tronlink chrome 扩展并尝试调用智能合约的 balanceOf 方法。我对智能合约很陌生。无法找到任何解决方案。请检查我的代码：

let contractDetail = await window.tronWeb.trx.getContract('TG7DLMkJPYeG4QTZ8Qfgk9Mu7ePM5SQpbN');
            let contract = await window.tronWeb.contract(contractDetail.abi.entrys, 'TG7DLMkJPYeG4QTZ8Qfgk9Mu7ePM5SQpbN');
            balance = contract.balanceOf.call('TNkJRejobNuZhV2LiwfGQ7wPNiLtcbDueS');
            console.log(balance)


//Error: Uncaught TypeError: Cannot read property 'call' of undefined

Answer 1

balanceOf 需要一个参数。

'balanceOf(address)'

而不是

contract.balanceOf.call('TNkJRejobNuZhV2LiwfGQ7wPNiLtcbDueS');

你应该把地址传入balanceOf

contract.balanceOf('TNkJRejobNuZhV2LiwfGQ7wPNiLtcbDueS').call();

Answer 2

使用tronWeb.trx.getBalance(CONTRACT_ADDRESS);

您的代码应该如下所示

balance = await tronWeb.trx.getBalance('TNkJRejobNuZhV2LiwfGQ7wPNiLtcbDueS');
