Trying to login into facebook with Powershell 6

I got to the point of logging in, but I get "Your request couldn't be processed" from facebook at the last step.

# Setup
#[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy
$ProgressPreference = 'SilentlyContinue'

# Session
$session = New-Object Microsoft.PowerShell.Commands.WebRequestSession
$session.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36"
$session.Cookies.Add((New-Object System.Net.Cookie("datr", "value", "/", ".facebook.com"))) # Used to set Allow Cookies to Accepted, replace value with your own value form the datr cookie.
$url = 'https://facebook.com/'

# Creds and Form
$login = Invoke-WebRequest -Uri $url -WebSession $session
$form = $login.Forms[0]
$credential = Get-Credential # or Import-CliXml cred.xml
$form.Fields["email"] = $credential.GetNetworkCredential().username
$form.Fields["pass"] = $credential.GetNetworkCredential().password

# Request
$facebook = Invoke-WebRequest -Uri $url -WebSession $session -Method POST -Body $form.Fields
#$facebook.Content

The idea: Run a powershell script, provide creds, it goes to Facebook, logs you in and outputs in the console how many photos you have in total.

Use Chromium-based browser DevTools to Generate the WebRequest code for you

By far the easiest way I've found to do this is to use Chrome's (or other chromium-based browsers) developer tools. The tools will generate all the code you need.

  • Go to the Facebook login page
  • Open the DevTools by pressing the F12 key
  • Open the Network panel
  • Enter your credentials
  • Click the "Log In" button
  • Locate the Post request in the list (should be near the top if you've just opened DevTools)
  • Right-click on the request and choose Copy > Copy as PowerShell.
  • Paste the code into a script file/VS Code/PowerShell ISE.
  • Remove ", br" from "accept-encoding"="gzip, deflate, br" from the headers hashtable or the response will NOT be readable
  • You can then use the $session variable in further requests
    • These requests can be generated the same way as the first from the DevTools network panel. Just remove all of the top $session lines so you don't overwrite the initial session cookies (and remove the br compression format again from the accept-encoding line).

Network Tab from Chrome DevTools

Generated code will look like something like this

$session = New-Object Microsoft.PowerShell.Commands.WebRequestSession
$session.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36 Edg/105.0.1343.33"
$session.Cookies.Add((New-Object System.Net.Cookie("fr", "0SmzDrtR5y3gEIe773d..BjT69C.eZ.AAA.0.0.BjHE333C.AWTZZ825DfGgk0", "/", ".facebook.com")))
$session.Cookies.Add((New-Object System.Net.Cookie("sb", "Qk8dY1sdf23MH4kHnd1F225Ap2akhXf", "/", ".facebook.com")))
$session.Cookies.Add((New-Object System.Net.Cookie("datr", "TEh3de4TYyf-7e2d36gFVo3wIpseiWg", "/", ".facebook.com")))
$session.Cookies.Add((New-Object System.Net.Cookie("wd", "881x863", "/", ".facebook.com")))

Through some trial and error this appears to be the bare minimum needed.

$session = New-Object Microsoft.PowerShell.Commands.WebRequestSession
# Keep from above generated code
$session.Cookies.Add((New-Object System.Net.Cookie('datr', 'TEh3de4TYyf-7e2d36gFVo3wIpseiWg', '/', '.facebook.com'))) 

$body = [ordered]@{
    lsd   = 'AVoElEJYWu0'  # Keep from above generated code
    email = 'test@gmail.com'  # update 
    pass  = 'mypassword123' # update
} 

$params = @{
    OutFile     = 'c:\temp\facebook.html'
    Uri         = 'https://www.facebook.com/login'
    Method      = 'POST'
    Headers     = @{
        'scheme' = 'https'
        'accept' = 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9'
    }
    WebSession  = $session
    ContentType = 'application/x-www-form-urlencoded'
    Body        = $body 
}
$response = Invoke-WebRequest @params -PassThru
