js实现一个可指定超时时间的异步函数重试机制

async function retryWithTimeout(fn, maxAttempts, delay, timeout) {
  let attempt = 0;
  while (attempt < maxAttempts) {
    try {
      const result = await Promise.race([fn(), timeoutPromise(timeout)]);
      return result;
    } catch (error) {
      console.error(`Attempt #${attempt + 1} failed with error: ${error.message}`);
      attempt++;
      if (attempt === maxAttempts) {
        throw error;
      }
      await delayPromise(delay);
    }
  }
}
function timeoutPromise(timeout) {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      reject(new Error('Timeout'));
    }, timeout);
  });
}
function delayPromise(delay) {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve();
    }, delay);
  });
}
