如何捕获来自 UrlFetchApp.fetchAll 的错误？

Question

UrlFetchApp.fetchAll speeds up the execution time. But with many requests, often occurs errors (429, 500, 503). In most cases, a second request will solve it. How can I catch them? According benchmark、HTTPResponse[] 与请求数组的顺序不同。因此我无法发送新请求 (UrlFetchApp.fetch)，不知道 url 和 params.

let requests = [
    { url: '', muteHttpExceptions: true }, 
    { url: '', muteHttpExceptions: true }
];
let responses = UrlFetchApp.fetchAll(requests);

Answer 1

According benchmark, HTTPResponse[] has a different order than request array.

我错了。总结部分给出了下一条规则：

After it worked by the asynchronous processing, the returned values is reordered by the order of requests.

在我的实践中，确实如此。
