google-chrome - how to generate HAR file in the Chrome?

Question

I want to use the function 'Preserve log' at the network tab in the Chrome Dev Tools. I searched internet and found following site. However, it does not work as it indicates. Does anyone have used preserve log and generate HAR file from it? Actually, I am wondering about the exact function of 'preserve log' itself.. Is is for generating HAR file?

Could you please help me out with this?

Answer 1

“保留日志：此选项与保存 HAR 文件不同。即使您刷新页面或移动到另一个页面，您也需要保留日志才能看到日志。但是，如果未选中此复选框，您将无法保存完整的 HAR 文件. 所以 HAR 需要“保留日志”，但它有其他含义。

Windows 上的HttpWatch可以通过在 Tools->Options->Recording 中启用自动记录来记录打开新 Chrome 选项卡或窗口时产生的网络流量。在新窗口中单击 HttpWatch 图标以查看网络跟踪。日志文件可以保存为 HAR 或本机 HttpWatch 格式 (HWL)

免费版将记录一个完整的 HWL 文件，该文件可由使用 HttpWatch Professional 的人打开。
