如何下載或訪問（‘web3/lib/web3/event.js’）；

以下測試腳本需要(‘web3/lib/web3/event.js’);

const SolidityEvent = require('web3/lib/web3/event.js');

function decodeLogs (logs, contract, address) {
return logs.map(log => {
const event = new SolidityEvent(null, contract.events[log.topics[0]],   address);
return event.decode(log);
});
}

module.exports = {
decodeLogs,
};

有誰知道我在哪裡可以找到該庫或者該庫是否隨 web3 下載一起安裝？？？

提前致謝 ！！

安裝truffle並使用npm install web3命令安裝web3。有關環境設置，請參閱本文。

答：只需要web3

const SolidityEvent = require('web3');

function decodeLogs (logs, contract, address) {
return logs.map(log => {
const event = new SolidityEvent(null, contract.events[log.topics[0]],      address);
return event.decode(log);
});
}

module.exports = {
decodeLogs,
};
