我正在使用谷歌应用程序脚本
var rss = "https://www.sec.gov/cgi-bin/browse-edgar?action=getcurrent&CIK=&type=8-k&company=&dateb=&owner=exclude&start=0&count=100&output=atom"
var r = UrlFetchApp.fetch(rss).getContentText()

但有时,我会收到执行失败的消息,这就是响应。大约是一半的时间。

不知道为什么会发生以及如何解决它。
尽管不幸的是,我无法复制您的情况,例如but once a while, I get a failed execution and this is the response.
,按如下方式重试请求怎么样?
var res = null;
var maxRetries = 5;
var rss = "https://www.sec.gov/cgi-bin/browse-edgar?action=getcurrent&CIK=&type=8-k&company=&dateb=&owner=exclude&start=0&count=100&output=atom";
for (var i = 0; i < maxRetries; i++) {
res = UrlFetchApp.fetch(rss, {muteHttpExceptions: true});
if (res.getResponseCode() == 200) break;
res = null;
Utilities.sleep(5000);
}
if (!res) throw new Error("Values cannot be retrieved.");
// do something.
var value = res.getContentText();

200
,5 秒后将重试请求。并且最大重试次数为5次。maxRetries
进行修改Utilities.sleep(5000)
