A small script for Powershell to export Lemmy profile settings. useful e.g. if the instance API is still working, but the frontend has problems (e.g. feddit.de problems)

Export-LemmyProfileSettings.ps1

# CHANGE THESE VALUES
$my_instance="https://feddit.de" # e.g. https://feddit.nl
$target_file = "C:\Temp\export.json"

#Ask user for username and password
$credentials = Get-Credential -Message "Logindata for $my_instance" -Title "Login"
$twoFACode = Read-Host -Prompt "2FA Code (leave empty if 2FA is not active)"

$my_username= $credentials.UserName
$my_password= $credentials.GetNetworkCredential().Password

# Lemmy API version
$API="api/v3"

# Login
function Get-AuthToken() {
    $end_point="user/login"
    $json_data= @{
        "username_or_email" = $my_username;
        "password" = $my_password;
        "totp_2fa_token" = $twoFACode
    } | ConvertTo-Json

    $url="$my_instance/$API/$end_point"

    (Invoke-RestMethod -Headers @{"Content-Type" = "application/json"} -Body $json_data -Method Post -Uri $url).JWT
}

# Get userdata as JSON
function Get-UserData() {
    $end_point="user/export_settings"

    $url="$my_instance/$API/$end_point"

    Invoke-RestMethod -Headers @{"Authorization"="Bearer $($JWT)"} -Method Get -Uri $url
}

$JWT= Get-AuthToken

Write-Host "Got JWT Token: $JWT"

Write-Host "Exporting data to $target_file"
Get-UserData | ConvertTo-Json | Out-File -FilePath $target_file

Now with support for 2FA enabled logins
