How to disable javascript in chromedp?


I want to disable javascript in https://github.com/chromedp/chromedp

any allocator flag can I put in the config? thank you!


Solution

  • There is a command line option: --blink-settings=scriptEnabled=false.

    package main
    
    import (
        "context"
        "log"
        "os"
    
        "github.com/chromedp/chromedp"
    )
    
    func main() {
        opts := append(chromedp.DefaultExecAllocatorOptions[:],
            chromedp.Flag("blink-settings", "scriptEnabled=false"),
        )
        ctx, cancel := chromedp.NewExecAllocator(context.Background(), opts...)
        defer cancel()
    
        ctx, cancel = chromedp.NewContext(ctx)
        defer cancel()
    
        var res []byte
        err := chromedp.Run(ctx,
            chromedp.Navigate(`https://twitter.com/`),
            chromedp.FullScreenshot(&res, 100),
        )
        if err != nil {
            log.Fatal(err)
        }
    
        os.WriteFile("screenshot.png", res, 0644)
    }
    

    FYI, the list of available blink-settings can be found here: https://source.chromium.org/chromium/chromium/src/+/09372ea8ec2ab6363ccad6a4847a1c9da560b29d:out/Debug/gen/third_party/blink/renderer/core/settings_macros.h;l=1535
