HttpRequestWeb ページのリクエストに使用するアプリケーションを開発しようとしています。問題は、OS 4.6.1 の接続文字列でサフィックスを取得する正しい方法がまだ見つからないことです。
ありがとう。

OS 5.0より前の接続文字列を作成するために使用したと思われるリンクは、次の2つでした。
http://docs.blackberry.com/en/developers/deliverables/34480/Network_transport_options_1293321_11.jsp
もちろん、BlackBerryはいくつかの異なるトランスポート（Wifi、WAP、BISなど）をサポートしています。使用するトランスポートを決定し、一度に使用できるトランスポートと優先度に応じて接続文字列を作成することをお勧めします。
これは、接続文字列のサフィックスの作成に役立つ、blackberry.comからダウンロードするサンプルコードです。実際のダウンロードについては、下部にある添付リンクを参照してください。

また、時間に追われていて、他の回答に記載されているリソースを読む時間がなく、簡単なコードが必要な場合は、BlackBerry の元の Facebook SDK に次のように見える実装があったことを覚えています。私が自分で書いたもの (申し訳ありませんが、私が書いたコードを投稿することはできません。それは私のクライアントのものだからです)。ただし、Facebook SDK の実装は無料で公開できるようです。もうリンクが見つかりませんが、お楽しみいただけるように以下に貼り付けます。
