Accessing Chrome DevTools Network Logs w/ 4.1.0 & Chome 97

[Jamie Brandwood]

Hi Selenium Community,

I'm fairly new to the Selenium world. But especially new to enabling the DevTools to extract a private API call from the netork logs.

Currently using Selenium WebDriver 4.1.0 w/ Chrome Driver 97. Everything seems to work as expected for my general browsing etc. But when i want to enable Netork Performance logging i get "perfLoggingPrefs specified, but performance logging was not enabled"

Snippet below if it helps (apologies its in PowerShell but any C# answers would be good):

    $ChromiumPerformanceLoggingPreferences = New-Object -TypeName OpenQA.Selenium.Chromium.ChromiumPerformanceLoggingPreferences

    $ChromiumPerformanceLoggingPreferences.IsCollectingNetworkEvents = $True

    $ChromiumPerformanceLoggingPreferences.IsCollectingPageEvents = $False

    $ChromeOptions = New-Object -TypeName OpenQA.Selenium.Chrome.ChromeOptions

    $ChromeOptions.AddUserProfilePreference('download.default_directory', $DefaultDownloadDirectory)

    $ChromeOptions.PerformanceLoggingPreferences = $ChromiumPerformanceLoggingPreferences

    $ChromeOptions.SetLoggingPreference([OpenQA.Selenium.LogType]::Browser, [OpenQA.Selenium.LogLevel]::All)

   

    $ChromeDriver = New-Object -TypeName OpenQA.Selenium.Chrome.ChromeDriver($ChromeDriverPath, $ChromeOptions)

Any advice would be much appreciated.

According to this https://chromedriver.chromium.org/logging/performance-log

"Performance logging is NOT enabled by default."

But according to a previous post here https://groups.google.com/g/selenium-users/c/77h8f67Z-rw/m/JY77oupSAQAJ

"... I'm using .NET to build this and LogType.PERFORMANCE is not an option for me."

Good luck.
