Can you add a function to add JS script for all browser's pages/tabs about rod

[ysmood]

Because PageAddScriptToEvaluateOnNewDocument is under the Page domain, so by its name it obviously should work only for a page instance 😂.

From its doc, you can find out that it's designed for navigation and iframes, not a hook for every new page.

Injecting a script to every page should follow the hook design pattern. So what you should do is listening to page creation events and run a script for each page.

I think I won't add an AddScriptOnEachDoc helper for you. But I'll an event helper to help you easily hook whatever you want.

v0.31.0 added some helpers to help you do this. Here's the example:

@zjlx v0.31.1 add browser.EachEvent helper to make it even easier:

@khaitranvan96kt Can you raise an issue about https://fingerprintjs.com? It's not bot detection, fingerprinting is another topic.

Yes I know, so I asked @zjlx

Against browser fingerprints, the above JS plug-in is only a fixed value, and it can't achieve random parameters. If you want more configuration, you need to implement it by yourself, learn about JS related knowledge such as webgl and canvas, and set different parameters to meet the requirements of simulating different browser fingerprints.

OK , Thanks a lot.

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
I used this code for fake browser fingerprint ,

proto.PageEnable{}.Call(page)

proto.PageAddScriptToEvaluateOnNewDocument{
	Source: fingerprint,
}.Call(page)

the js code from https://github.com/berstend/puppeteer-extra/tree/master/packages/puppeteer-extra-plugin-stealth
I don't known why need proto.PageEnable ,but if I don't write it the proto.PageAddScriptToEvaluateOnNewDocument not works.
proto.PageAddScriptToEvaluateOnNewDocument only works on current page/tab not working on a link click new pages/tabs.

Can you add a function to add JS script for all browser's pages/tabs something like hook browser's page or some network.
Thanks.

Can you give me the Script to fake the fingerprint?

@khaitranvan96kt You might want to use stealth lib to bypass the bot detection.

[khaitranvan96kt]

func TestRequestFingerprint2(t *testing.T) {
	for i := 0; i < 3; i++ {
		browser := rod.New().Connect()
		page := bypass.Page(browser)
		page.Navigate("https://fingerprintjs.com/demo").WaitLoad()
		time.Sleep(10 * time.Second)
		filename := fmt.Sprintf("browser_%d.png", i)
		page.ScreenshotFullPage(filename)
		browser.Close()
	}
	fmt.Println("All done, check the screenshot. ✨")
}

It does not work, it is still detected. I wanted to create 3 different browsers, but it was still discovered to be the same.

wow, thank you so much for suggesting me
