PowerShell to check for Build Sheet

[TurpJL]

My build sheet became available today, so I know this at least worked for me and thought I would share.

I was bored a while back and wrote a PowerShell script to go check for the build sheet so I did not have to do it everyday. I assume CryptoSticker uses some similar logic because I got the notification from there right after mine.

Change the VIN in the $URL to match yours, open PowerShell, paste it in and hit enter. Once found, it will open your default browser with the buildsheet.

If your build sheet is there, you should be able to change the $URL to check for the Window Sticker instead:
$URL = "https://www.chrysler.com/hostd/windowsticker/getWindowStickerPdf.do?vin=1C4HJXFG7JWXXXXXX"

If I had to do this more often than my vehicle, this could be cleaned up quite a bit:

$Check = 0
$URL = "https://www.jeep.com/webselfservice/BuildSheetServlet?vin=1C4HJXFG7JWXXXXXX"

While ($Check -eq 0) {

if ((Invoke-WebRequest -Uri $URL).Rawcontentlength -gt 1200) {
Write-host "Build Sheet Available"
$check = 1
Start-Process $URL}

Else
{write-host "No Build Sheet"
#Sleep for 8 hours before checking again
Start-Sleep -Seconds 28800}
}​

Nice job! Always fun to see community code creations/contributions. For no particular reason, I decided I wanted to refactor your script a bit, having no prior knowledge of Powershell.. here's the fruits of that labor:

• Added some sass to the informational messages (why not?)
• Added window sticker checking (was only build sheet checking before)

[Jeep]::statusCheck("1C4HJXFG3JWXXXXXX")

class Jeep {
    
    # Class properties
    hidden $Options = @{
        Vin = "";
        Timer = 28800;
        Types = @{
            BuildSheet = @{
                url = "https://www.jeep.com/webselfservice/BuildSheetServlet?vin=";
                found = $false;
            }
            WindowSticker = @{
                url = "https://www.jeep.com/hostd/windowsticker/getWindowStickerPdf.do?vin=";
                found = $false;
            }
        };
        Loop = $true
    }

    # Named Constructor
    static [Jeep] statusCheck($Vin) {
        return [Jeep]::New($Vin)
    }

    # Constructor
    Jeep ([String] $Vin) {
        $this.Options.Vin = $Vin

        While ($this.Options.Loop) {
            $this.checkBuildSheet()
            $this.checkWindowSticker()
            $this.handleLoop()

            # Sleep for 8 hours before checking again
            # Start-Sleep -Seconds 28800
            Start-Sleep -Seconds $this.Options.Timer
        }
    }

    # Creates a timer to continually check for status updates
    [Void] handleLoop() {
        $continueLoop = $true
        foreach ($type in $this.Options.Types.Keys) {
            if ($this.Options.Types.$type.found) {
                $continueLoop = $false
            } else {
                $continueLoop = $true
            }
        }

        if (!$continueLoop) {
            $this.log("Nothing left to check! Now exiting...")
            exit
        }

        $this.log("I will check for you again soon!")
        Write-Host ""

        $this.Options.Loop = $continueLoop
    }

    # Sets the found status for the type of check
    [Void] setStatus([String] $type, [Bool] $status) {
        $this.Options.Types.$type.found = $status
    }

    # Gets the status for the type of check
    [Bool] getStatus([String] $type) {
        return $this.Options.Types.$type.found
    }

    # Wrapper for Write-Host, appends datetime or whatever you want to the output
    [String] log([String] $data) {
        return Write-Host "[$(Get-Date -Format g)] $data"
    }

    # Creates the request to the webpage
    [Bool] Request([String] $type) {
        if (!$this.Options.Types.ContainsKey($type)) {
            throw "An incompatible type was provided. Please specify wether you want to check for a buildsheet or windowsticker"
        }

        $url = $this.Options.Types.$type.url + $this.Options.Vin

        return (Invoke-WebRequest -Uri $url).Rawcontentlength -gt 1200
    }

    # Checks for build sheet availability
    [Void] checkBuildSheet() {
        $type = "BuildSheet"
        if (!$this.getStatus($type)) {
            if ($this.Request($type)) {
                $this.log("Build sheet available! Stand by, launching your browser...")
                $this.setStatus($type, $true)
                Start-Process ($this.Options.Types.$type.url + $this.Options.Vin)
            } else {
                $this.log("No build sheet detected :(")
            }
        }
    }

    # Checks for window sticker availability
    [Void] checkWindowSticker() {
        $type = "WindowSticker"
        if (!$this.getStatus($type)) {
            if ($this.Request($type)) {
                $this.log("Window sticker available! Stand by, launching your browser...")
                $this.setStatus($type, $true)
                Start-Process ($this.Options.Types.$type.url + $this.Options.Vin)
            } else {
                $this.log("No window sticker detected :(")
            }
        }
    }
}

It's obviously overkill for it's purpose, but it was fun. Also I coded this on my macbook and did not test this on windows at all. Who knows what bugs exist! But it does seem to work for the light testing I did.
