Why enable the browser to have two tabs and not open the web properly? #306

smp12345 · 2020-12-11T01:17:23Z

Rod Version: v0.84.3
chrome Version: 版本 87.0.4280.88（正式版本）
go Version ： go1.14.4 windows/amd64
Windows7

sample code：

package main

import (
	"github.com/go-rod/rod"
	"time"
)

func main() {
	page := rod.New().MustConnect().MustPage("https://www.baidu.com/")
	page.MustWaitLoad().MustScreenshot("a.png")
	time.Sleep(time.Hour)
}

When running the code above, chrome will open two browser window directly, one of the Windows web site: file:///C:/Users/ADMINI~1/AppData/Local/Temp/rod/self-close.html, the other is a blank page, baidu.com is not normal to open

Help me, thank you

smp12345 · 2020-12-11T01:37:50Z

I use the sample code of the official website. After opening the browser, two tabs will be opened directly. My computer is Windows 7, and the test on Ubuntu last night is normal, please refer to the screenshot above.What other information do I need to provide?

ysmood · 2020-12-11T01:41:01Z

Works fine with Windows10, sorry I don't know how to reproduce it:

smp12345 · 2020-12-11T01:45:19Z

What's the meaning this path: file:///C:/Users/ADMINI~1/AppData/Local/Temp/rod/self-close.html ?

smp12345 · 2020-12-11T01:46:02Z

I'm using Chrome 87, which should be up to date

ysmood · 2020-12-11T01:47:06Z

What's the meaning this path: file:///C:/Users/ADMINI~1/AppData/Local/Temp/rod/self-close.html ?

It's the default StartURL, please read the doc:

rod/lib/launcher/launcher.go

Lines 41 to 46 in 5ebed67

    
           // New returns the default arguments to start browser. 
        
           // Headless will be enabled by default. 
        
           // Leakless will be enabled by default. 
        
           // UserDataDir will use OS tmp dir by default. 
        
           // StartURL will be set to GetSelfClosePage(). 
        
           func New() *Launcher {

smp12345 · 2020-12-11T01:48:46Z

I tested ubuntu last night and saw only a TAB, not this one, just go to Baidu.com

ysmood · 2020-12-11T01:51:16Z

Can you try this code?

package main

import (
	"time"

	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/launcher"
)

func main() {
	u := launcher.New().StartURL("about:blank").MustLaunch()
	page := rod.New().ControlURL(u).MustConnect().MustPage("https://www.baidu.com/")
	page.MustWaitLoad().MustScreenshot("a.png")
	time.Sleep(time.Hour)
}

smp12345 · 2020-12-11T01:54:39Z

Open two blank pages, there is no url I sent above

ysmood · 2020-12-11T01:56:22Z

Seems like Chrome crashed, not sure about why is happening. I don't have Window7 to test it, not sure how to help.

smp12345 · 2020-12-11T01:58:50Z

Can you install a virtual machine and test it out?Thank you very much.After all, Windows 7 still has a large user base

ysmood · 2020-12-11T02:01:43Z

Sure, I just don't have time for it now, I will check when I have time. Thank you for your report!

Can you share more debug info? To enable it is easy just add one line to the .rod file, so your .rod looks like:

show
cdp

Then provide your console log to us.

Seems like an upstream Chrome bug. Can you run this:

	"github.com/go-rod/rod/lib/launcher"
)

func main() {

}

smp12345 · 2020-12-11T02:12:03Z

There is only one blank page after loading

smp12345 · 2020-12-11T02:13:33Z

There are two blank pages first, and then a blank page is automatically closed

smp12345 · 2020-12-11T02:14:59Z

I tested it on another win7 and had exactly the same problem.

Thank you, I think it's enough now, we will test Win7 later. I missed this OS because seldom developers nowadays still use Win7.

@NormalPunch is checking Win7.

smp12345 · 2020-12-11T02:33:26Z

Thank you. This is my first time using this framework, and I feel the documentation is excellent.I used Chromedp before, and it worked fine, but It didn't feel stable enough to fail when I clicked on an element multiple times

smp12345 · 2020-12-11T02:35:30Z

Although the development of people using Win7 is not much, but the user use Win7 or a lot of my customers are Win7, Win7 this system or do not give up, thank you

smp12345 · 2020-12-14T08:54:43Z

@ysmood After your repair, the Baidu website can be normally opened, but there is an extra blank page. How to remove this blank page

ysmood · 2020-12-14T09:09:36Z

@smp12345 Don't remove it, the reason is the last line of here: https://pkg.go.dev/github.com/go-rod/rod@v0.85.4/lib/launcher#New

smp12345 · 2020-12-14T09:31:05Z

I see what you mean, but in this case, the user experience is not very good. Can We use the MustPage url as an active page?

smp12345 · 2020-12-14T09:37:18Z

I mainly use this framework for automation, it would be better to automate the interface, I need to see the process of execution, but there is an extra blank page, it doesn't look comfortable @ysmood

ysmood · 2020-12-14T14:03:37Z

This commit should have fixed your issue 475b659

Please check v0.85.6

smp12345 · 2020-12-15T01:36:33Z
