问题描述

我认为，根据Chromium的网络"标签，window.performance.getEntries()将与请求数量匹配，但事实并非如此: http://i.stack.imgur.com/OfKtH.png .我想念什么?

I thought that window.performance.getEntries() would match the number of requests according to Chromium's 'Network' tab, but that doesn't seem to be the case: http://i.stack.imgur.com/OfKtH.png. What am I missing?

推荐答案

在我的情况下，某些请求丢失了，这些请求是在页面完成加载后发生的. 网络"选项卡显示了所有请求，但window.performance.getEntries()仅显示了响应原始页面调用的那些用户(而不显示页面上以后的操作).我相信performance.getEntries()和资源计时API 只关心页面的原始建筑.

In my Case some Requests were missing, which occurred after the Page had finished loading. The Networking Tab showed all Requests, but window.performance.getEntries() only Showed those who responded to the original Page Call (and not later actions on the Page). I believe performance.getEntries() and the Resource Timing API only concern themselves with the original building of the Page.
