Question

假设我有一个返回Promise的函数：

let logData = function () {
    return new Promise(function (resolve, reject) {
        // doing some stuff
        resolve('data');
    });
};

假设我有一个resolve回调的回调函数：

let resolveCallback = function (data) {
    console.log(`doing some stuff with ${data}`);
};

当我只使用没有async-await的promise时，我可以很容易地将此回调传递给promise，就像这样：

logData().then(resolveCallback);

在此示例中，当我执行诺言时，它将到达resolve('data');行，并且resolveCallback将被执行，因为resolve = resolveCallback

现在，当我使用async-await方法时，是否有可能以某种方式将resolveCallback传递到Promise中？

async function logDataAsync() {
    // IS THERE NO WAY TO PASS resolveCallback as resolve PARAMETER HERE???
    await logData();
}

Answer 1

async function logDataAsync() {
// IS THERE NO WAY TO PASS resolveCallback as resolve PARAMETER HERE???
    const res = await logData();
    resolveCallback(res);
}

与

相同

logData().then(resolveCallback)

使用异步等待时如何将Resolve回调传递给Promise？
