从理论上讲，这种方法似乎是合理的，特别是因为已知的 异步执行 。

• .fetch() 调用是实际获取的地方。因此，对UrlFetchApp对象的任何钩子都应该在 fetch 调用之前插入。
• 您可以使用 Proxy object 连接到 UrlFetchApp 上的 .fetch 调用，以返回带有 thenable 对象的虚拟 HTTPResponse 。
• 然后，如问题中所述，在 .getContent 调用上使用 .getContent 。
• 但是，请注意，应用程序脚本中的承诺可能会执行，也可能不会像 发布注释#1至#4 中所说的那样异步执行。然而，这不应该是您的方法的一个问题。

考虑到承诺的微妙性质和不明确的文档，最好在任何生产环境中避免它们。实现批处理请求的更好方法是对 thenable 对象使用普通的自定义函数：

function test() {
   * @description Batches requests until then is called on a response
   *   and fetches all batched requests
   * @return {object} A then object, which when called fetches the batch
   * @param {string} url Url to fetch
   * @param {object} options Options to fetch. See UrlFetchApp.fetch
  const fetchAsBatch = function fetch(requests, url, options) {
    options.url = url;
    requests.add(options);
    return {
      then: func => {
        const responses = func(UrlFetchApp.fetchAll([...requests]));
        requests.clear();// clear current batch
        return responses;
  }.bind(this, new Set());
  const successHandlerLogger = responses => {
    /*Do something with all responses*/
    console.log(responses.map(response => response.getContentText()));
  fetchAsBatch('https://example.com', { method: 'get' });
  fetchAsBatch('https://httpbin.org/post', { method: 'post' }).then(
    successHandlerLogger
  fetchAsBatch('https://google.com', {}).then(successHandlerLogger);
}
