Is there a way to change or get download directory of browser?

[sunaynat]

Scenario which I am trying to test is a downloaded document has the same filename as the one I uploaded in earlier part or the test. And when running the test case in different OS the download directory changes. Is there a way to either set the directory to something or get the directory so that I can assert on the downloaded file.

working on v0.114.5

Please add a valid Rod Version: v0.0.0 to your issue. Current version is v0.114.5

The WaitDownload method allows you to specify the dir:

rod/browser.go

Line 504 in d2ad7cb

func (b *Browser) WaitDownload(dir string) func() (info *proto.PageDownloadWillBegin) {

[sunaynat]

if I specify in waitdownload then my file gets downloaded with alphanumeric characters and not with the original filename. And if I dont use waitdownload then it gets downloaded in downloads folder with the correct filename

Then you need to config the preference of the browser to change the download folder:

rod/lib/launcher/launcher.go

Line 248 in 009545e

func (l *Launcher) Preferences(pref string) *Launcher {

It's a json value like this:

rod/lib/launcher/launcher.go

Line 69 in 009545e

flags.Preferences: {`{"plugins":{"always_open_pdf_externally": true}}`},

The doc of all preference:

https://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/pref_names.cc?view=markup#l1443

tried this, it did not work. Still it gets downloaded in downloads folder
launcher.New().Preferences({"download":{"default_directory": +mydir+}}).
Also tried with ""savefile":{"default_directory":"/Users/xyz/"}"
and savefile.default_directory

Another way to find out the correct key is to check a real pref when you config the chrome with the browser's settings page, so you don't need to guess it

savefile.default_directory this mentioned in doc

I added this preference also downloadPrefernce := "{"download.default_directory":"/Users/xyz/"}"
and tried with savefile as well but nothing is working. Also in prefernces file also I checked in my system, it doesn't update the file with any way I tried.

Works fine to me:

package main

import (
	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/launcher"
	"github.com/go-rod/rod/lib/utils"
)

func main() {
	pref := `{
  "download": {
    "default_directory": "/Users/yad/Downloads/ttt"
  }
}`

	l := launcher.New().Preferences(pref).Headless(false)

	u := l.MustLaunch()

	rod.New().ControlURL(u).MustConnect().MustPage()

	utils.Pause()
}
