我正在创建Chrome扩展程序。我从DevTools面板检索了HAR对象。我可以从HAR对象获取“加载”和“ DOMContentLoaded”时间,
pages: [
{
"startedDateTime": "2019-03-07T22:16:02.333Z",
"id": "page_2",
"title": "https://xxxx",
"pageTimings": {
"onContentLoad": 1635.4740000006132,
"onLoad": 2318.5020000000804
}
}
]
现在,如何从HAR对象计算7.75 s的“完成”时间,如下所示?
答案 0 :(得分:0)
所以,我已经弄清楚了,
FinishTime =(lastRequestStartedTime + lastRequestDuration )-(firstRequestStartedTime)
const requests=harObject.entries;
const lastRequest = requests.reduce(
(a, b) => {
return a.startedDateTime > b.startedDateTime ? a : b;
}
);
const firstRequest = requests.reduce(
(a, b) => {
return a.startedDateTime < b.startedDateTime ? a : b;
}
);
//Finish Time in Seconds
const finishTime=`((Date.parse(lastRequest.startedDateTime) + lastRequest.time
- Date.parse(firstRequest.startedDateTime))
/ 1000).toFixed(2)
