Question

I am developing a chrome extension to capture the network tab related data in chrome dev tools. my code as follows

manifest.js

{
  "name": "Entries",
  "version": "1.0",
  "description": "Give me entries",
  "devtools_page": "devtools.html",
  "manifest_version": 2
}

devtools.js

chrome.devtools.network.getHAR(function(result) {
  var entries = result.entries; 
  Console.warn("entries : " + entries.length);          
});

getting the following error in console tab

Uncaught TypeError: Cannot read property 'network' of undefined

Chrome不允许用户从devtools读取网络日志，这意味着在devtools中运行脚本之前，您无法访问网络信息。要实现此目的，您需要创建一个新选项卡。 devtools帮助面板并在面板中运行脚本。
