Could you please tell me, is this a global issue, does WebDriver UDF generally work reliably? Are there any occasional "wandering glitches"? I have a script that sometimes works perfectly, and other times doesn't work at all.

I just can't grasp it - is WebDriver a stable library or can there be intermittent glitches?

I understand that without code, there isn't much point, I will try to provide it a bit later.

But yes. I have started a While loop and notice that around the 20-30th iteration, WebDriver stops functioning correctly.

Moreover, the chrome.exe process does not persist, so the issue lies there (the launched process remains).

MsgBox(64,'','We will load the service page.')
        _WD_CapabilitiesAdd('args', '--app=https://0.0.0.0')
        _WD_SetTimeouts($sSession, '{"pageLoad":2000}')
        _WD_LoadWait($sSession)
        _WD_Navigate($sSession, 'chrome://version/') ;service page (to get the window to display at all)
        _WD_LoadWait($sSession)
        MsgBox(64,'','Has the test page loaded??')

In this particular segment, an error occurs once every five successful runs. Any ideas on what this might be related to?

    _WD_LoadWait($sSession)
    ;_WD_DeleteSession($sSession)
    _WD_Shutdown()

    Return $hSessionWindow
EndFunc   ;==>_WD_ChromeStart

Here is the function, for unclear reasons, it sometimes works and sometimes doesn't. What could be the issue? The problematic section is == ! PROBLEM ! ==

 

The issue has been resolved. It was all about _WD_SetTimeouts($sSession, '{"pageLoad":2000}'). 
I hope this will be helpful to someone!

Could you please advise on which parameter needs to be added to make the --app mode work? (opening a website as an application)

  

_WD_CapabilitiesStartup()
    $r = Random(1, 999, 1)
    _WD_CapabilitiesAdd('alwaysMatch', 'chrome' & $r)
    _WD_CapabilitiesAdd('firstMatch', 'chrome' & $r)
    _WD_CapabilitiesAdd('browserName', 'chrome' & $r)
    _WD_CapabilitiesAdd('excludeSwitches', 'enable-automation')
    _WD_CapabilitiesAdd('unhandledPromptBehavior', 'ignore')
    _WD_CapabilitiesAdd('acceptInsecureCerts', True)
    _WD_CapabilitiesAdd('w3c', True)
    _WD_CapabilitiesAdd('detach', False)

    _WD_CapabilitiesAdd('args', '--user-data-dir=' & $sProfile)
    _WD_CapabilitiesAdd('binary', $sBinary)
    _WD_CapabilitiesAdd('args', '--force-renderer-accessibility')
    _WD_CapabilitiesAdd('args', '--remote-debugging-port=' & $sPort)
    _WD_CapabilitiesAdd('args', '--app=https://00.00.00.00')

Привет,

Описание проблемы и ее решения расплывчатое. Что происходит, когда "совсем не работает"? Можете показать вывод в консоли Scite с ошибками?

Вы удалили вызов _WD_SetTimeouts или было какое-то другое решение?

С уважением,

Дэн

However, the issue is not about that. The problem is that I just can't seem to launch two Chrome windows. I want them both to work in app mode, like applications.

Moderators! Please delete this topic, as it's really confusing here.

I just can't seem to launch two Chrome windows in app mode. I need to be able to control each one. I can launch two windows in app mode simultaneously, but that's not what I need.

Here's an example of what I'm trying to do:

  

#include 'wd_core.au3'
#include 'wd_capabilities.au3'
#include 'wd_helper.au3'


;$sURL = 'https://google.com'
;$sProfile = 'D:\MyTextarea\CHROME_MUSIC\PROFILE'
;$sBinary = 'D:\MyTextarea\CHROME_MUSIC\BINARY\chrome.exe'


$_WD_GetFreePort = _WD_GetFreePort()
_WD_Option('Driver', 'chromedriver.exe')
_WD_Option('Port', $_WD_GetFreePort)
FileDelete(@ScriptDir & '\_WD_ChromeStart.log')
_WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\_WD_ChromeStart.log" --port=' & $_WD_GetFreePort)

_WD_CapabilitiesStartup()

_WD_CapabilitiesStartup()
_WD_CapabilitiesAdd('alwaysMatch', 'chrome')
_WD_CapabilitiesAdd('firstMatch', 'chrome')
_WD_CapabilitiesAdd('browserName', 'chrome')
_WD_CapabilitiesAdd('excludeSwitches', 'enable-automation')
_WD_CapabilitiesAdd('acceptInsecureCerts', True)
_WD_CapabilitiesAdd('w3c', True)
_WD_CapabilitiesAdd('detach', False)
;_WD_CapabilitiesAdd('args', '--user-data-dir=' & $sProfile)
;_WD_CapabilitiesAdd('binary', $sBinary)
_WD_CapabilitiesAdd('args', '--force-renderer-accessibility')
_WD_CapabilitiesAdd('args', '--remote-debugging-port=9222')
;_WD_CapabilitiesAdd('debuggerAddress', '127.0.0.1:9222')
_WD_CapabilitiesAdd('args', '--app=https://0.0.0.0')

_WD_Startup()

$_WD_CapabilitiesGet = _WD_CapabilitiesGet()

$sSession1 = _WD_CreateSession($_WD_CapabilitiesGet)
$sSession2 = _WD_CreateSession($_WD_CapabilitiesGet)

_WD_Navigate($sSession1,  'https://google.com') ;not working
_WD_Navigate($sSession2,  'https://bing.com') ;not working

_WD_Shutdown($sSession1)
_WD_Shutdown($sSession2)

It's the third tread asking basically the same question about WebDriver. It's Sunday, wait some time and give people a chance to reply to your question.

I am terribly sorry, it happened accidentally. Usually I search for solutions on my own and for a very long time, but this time I am powerless.

There's no need to quote me in your response, but please use English if you insist on doing it as this is an English language forum. It seems like your other thread is related to this one, so maybe you should request the moderators to combine them.

FWIW, launching two separate browser windows isn't difficult using Webdriver, so I suspect that there is something you haven't explained fully about your particular requirements.

$sAttach1 = _WD_Attach($sSession2,'https://0.0.0.0','url') ;not working
$sAttach2 = _WD_Attach($sSession2,'https://0.0.0.0','url') ;not working
_WD_Navigate($sAttach2, 'https://bing.com')
_WD_Navigate($sAttach1,  'https://google.com')

Unfortunately, this also does not work.

As I mentioned elsewhere, "not working" isn't a sufficient description of the problem. After a brief look at your code, I suspect that some of your problems arise because you are trying to use the same user profile in two different sessions.

You were right. Yes, indeed, if different profiles - you can open two windows in app mode.

BUT there is another way to do it:

1. Open a window with the command _WD_CapabilitiesAdd('args', '--remote-debugging-port=9223')
2. Then connect to that window with the command _WD_CapabilitiesAdd('debuggerAddress', '127.0.0.1:9223')
This also works! In the end, I managed to find two ways! :)

  

#include 'wd_core.au3'
#include 'wd_capabilities.au3'
#include 'wd_helper.au3'


$_WD_GetFreePort = _WD_GetFreePort()
_WD_Option('Driver', 'chromedriver.exe')
_WD_Option('Port', $_WD_GetFreePort)
FileDelete(@ScriptDir & '\_WD_ChromeStart.log')
_WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\_WD_ChromeStart.log" --port=' & $_WD_GetFreePort)

_WD_CapabilitiesStartup()

_WD_CapabilitiesStartup()
_WD_CapabilitiesAdd('alwaysMatch', 'chrome')
_WD_CapabilitiesAdd('firstMatch', 'chrome')
_WD_CapabilitiesAdd('browserName', 'chrome')
_WD_CapabilitiesAdd('excludeSwitches', 'enable-automation')
_WD_CapabilitiesAdd('acceptInsecureCerts', True)
_WD_CapabilitiesAdd('w3c', True)
_WD_CapabilitiesAdd('detach', False)
_WD_CapabilitiesAdd('args', '--user-data-dir=D:\MyTextarea\CHROME_MUSIC\PROFILE')
_WD_CapabilitiesAdd('binary', 'D:\MyTextarea\CHROME_MUSIC\BINARY\chrome.exe')
_WD_CapabilitiesAdd('args', '--force-renderer-accessibility')
_WD_CapabilitiesAdd('args', '--remote-debugging-port=9223') ; <<< IMPORTANT <<<
;_WD_CapabilitiesAdd('debuggerAddress', '127.0.0.1:9223') ; <<< IMPORTANT <<<
_WD_CapabilitiesAdd('args', '--app=https://0.0.0.0')

_WD_Startup()

$_WD_CapabilitiesGet = _WD_CapabilitiesGet()

$sSession1 = _WD_CreateSession($_WD_CapabilitiesGet)

_WD_Navigate($sSession1,  'https://bing.com') ; <<< when using the debuggerAddress command, you simply change the address, for example to https://bing.com

Please write down any comments or nuances.

Sorry for my English.

I will be glad to see your comments.

This task is probably impossible for me. Help me please.
