scripting - Auto Login to a website using powershell

Question

I am getting following error message when i am running my powershell script

The property 'value' cannot be found on this object. Verify that the property exists and can be set.
At C:Test.ps1:17 char:1
+ $usernamefield.value = $username

My script:

$ie = New-Object -ComObject 'internetExplorer.Application'
$ie.Visible= $true # Make it visible

$usernmae="test"

$password="test1"

$ie.Navigate("https://website.com/login")

While ($ie.Busy -eq $true) {Start-Sleep -Seconds 3;}

$usernamefield = $ie.document.getElementByID('ysi_email')
$usernamefield.value = $username

$passwordfield = $ie.document.getElementByID('ysi_password')
$passwordfield.value = $password

$Link = $ie.document.getElementByID('ysi_btn_login')
$Link.click()

I cant seem to understand the problem here, i have looked into other examples within stackoverflow but i still cant find the problem.

The same id works fine in another example in a python script.

Here is a screenshot

Answer 1

The problem comes from the fact that object of IDs 'ysi_email', 'ysi_password' and 'ysi_btn_login' are not found in the DOM of the document loaded at https://website.com/login.

To solve your trouble load your document in Chrome, or Firerfox or Explorer with the developpers tools activated (Press F12) and inspect the objects you want to find.

Here is a working solution according to your comments :

$ie = New-Object -ComObject 'internetExplorer.Application'
$ie.Visible= $true # Make it visible

$username="test@toto.fr"

$password="test1"

$ie.Navigate("https://To your detailled URL")

While ($ie.Busy -eq $true) {Start-Sleep -Seconds 3;}

$usernamefield = $ie.document.getElementByID('ysi_email')
$usernamefield.value = "$username"

$passwordfield = $ie.document.getElementByID('ysi_password')
$passwordfield.value = "$password"

$Link = $ie.document.getElementByID('ysi_btn_login')
$Link.click()

$ie.Quit()

Here you can see the result for me.
