omfg thank you so much

Hello,
I was playing with the API and I got an error:
{ "RetCode" : -109, "Message" : "app id error", "Data" : null }
I tried different account genshin impact account to get different url but still the same error

Né

On line 23, I think you need to pipe the match through select -Last 1. Today the script was not working as expected and I figured out that there were multiple matching lines in the log.

$match = $logs -match "^OnGetWebViewPageFinish.*log$" | select -Last 1

You can use $env:<varname> to get environment variables. Incorporating @ginwantsplay's suggestion, you can replace lines 15 through 22 with:

$logLocation = "$env:USERPROFILE\AppData\LocalLow\miHoYo\Genshin Impact\output_log.txt"
$apiHost = "hk4e-api-os.mihoyo.com"
if (-Not [System.IO.File]::Exists($logLocation)) {
    # Using [char](0xnnnn) avoids concerns about the script's encoding
    $logLocation = "$env:USERPROFILE\AppData\LocalLow\miHoYo\$([char]0x539f)$([char]0x795e)\output_log.txt"
    $apiHost = "hk4e-api.mihoyo.com"
    if (-Not [System.IO.File]::Exists($logLocation)) {     
        Write-Host "Cannot find the log file! Make sure to open the wish history first!" -ForegroundColor Red
        exit
    }
}

$logs = Get-Content -Path $logLocation

and then on line 36:

$uri.Host = $apiHost

Credit to @Nats-ji for the cast-to-character trick from their fork here.

Fixed it for 3.0+ 4.6+ 4.8+

Version 4.6 fix:
$uri.Path = "event/gacha_info/api/getGachaLog" is now $uri.Path = "gacha_info/api/getGachaLog"

Doesn't seem to work with Cloudflare WARP enabled
