javascript - 如何正确解决 Promise 和 wait 问题？

Question

有人可以告诉我为什么 await 在这里不起作用吗？

const Web3 = require('web3');

web3 = new Web3(new Web3.providers.HttpProvider("http://<ip>:8545"));

let accounts = (async () => await web3.eth.getAccounts())();

// await was not working, here I get a promise
console.log(accounts);

// if I wait with a timeout I get my accounts
setTimeout(() => console.log(accounts), 5000);

Answer 1

您的 console.log 必须位于内联异步函数内。

(async () => {
   accounts = await web3.eth.getAccounts()
   console.log(accounts);
}
)();
