计算经过的时间异步函数javascript [重复]

Question

我想计算每个呼叫响应的经过时间并将其显示在一个文件中。

承诺函数

function callPromise(ms, promise) {
    return new Promise((resolve, reject) => {
        const timeoutId = setTimeout(() => {
            reject(new Error(`Timeout after ${ms} ms`))
        }, ms);
        promise.then(
            (res) => {
                clearTimeout(timeoutId);
                resolve(res);
            },
            (err) => {
                clearTimeout(timeoutId);
                reject(err);
            }
        );
    })
}

响应调用

        const response = await callPromise(10, fetch(url, {
            method: request.method,
            headers: header,
            body: body
        }))

Answer 1

与console.time() ?

console.time("Elapsed time :");
const response = await callPromise(...);
console.timeEnd("Elapsed time :"); // Will log "Elapsed time : 6.9165ms"
