ポッドキャストはとてもエキサイティングだったので、私は自分を引き裂くことができませんでした。 そして、私は地下鉄で彼の話を聞くのがいいだろうと決めました。 そのため、USBフラッシュドライブのようなコンピューターに接続できるPDAがあります。
ここから、2つのタスクがありました。
- PDAで残りのポッドキャストをダウンロードする
- PDAの終了時にポッドキャストをダウンロードする
働くために！
プログラマーにとって解決できない問題はありません。最初の問題を解決します。 URLベースのページからすべてのポッドキャストをダウンロードするスクリプトが必要です。 良い機能は、ポッドキャストが既にメディアに存在する場合に停止することです（新しいもののみをダウンロードする場合）。
作業の過程で、次のスクリプトを入手しました。
