ChatGPTのAPIを使って、Perlでrole処理しながらチャットサイトを作ってみる。

category:Perl
通常のWEBでアクセスしてチャットするみたいなのをAPIつかって自前で作成してみました。
そんなの普通に使えば必要ないじゃんって事ですが、複数人数で利用する場合一つのアカウントを使いまわすことは規約的にNGなので、社内用に作ってみました。
そこからシンプルな形に一部削って掲載してます。
GPT4をAPIで叩くには、一度課金が発生しないと使えない場合があるそうなので一旦ガンガン回して課金してから有効にする必要があるかもです。
以下ソースコード。細かい処理は適当です、参考程度に。
