如何获取含动态加载链接/图片的完整网页及可用离线副本？
Hey folks, I've dug through a bunch of Stack Overflow threads about this exact issue, and here's what I've found:
The Problem with Popular Tools Like wget & httrack
Most top-voted answers recommend these command-line tools, but they fall flat hard when dealing with modern, dynamic web content:
- They can't properly handle content loaded dynamically via JavaScript
- They struggle to recognize images using the
srcsetattribute instead of the standardsrc - Dynamic links generated on the fly are often completely missed
Selenium: The Obvious (But Imperfect) Fix
Let's be real—anyone who's used Selenium knows it's a game-changer here. Unlike wget/httrack, it simulates a real browser, rendering the full page just like a human would. That means it picks up all JS-loaded content, srcset images, and dynamic links without breaking a sweat.
Of course, it's not all sunshine and roses: Selenium is slower than lightweight command-line tools, requires setting up browser drivers, and can be resource-heavy if you're scraping at scale. But when the other tools fail you, it's usually the go-to solution for these tricky dynamic pages.
