python - SUDS クライアントで urlopen エラー [Errno 11001] getaddrinfo が失敗しました (Python3.2 + WCF WS)

Question

Python3.2 (SUDS ライブラリ 0.4.1) で Web サービスに接続する際に問題があります。非 wcf Web サービスに接続すると、すべて正常に動作します。次のようにオブジェクト Client クラスを作成します。

Client("http://xxxxxx.xx/XXX_2.0/RequestsService.asmx?wsdl")

しかし... wcfサービスでもまったく同じことをしたい:

Client("http://xxxxxx.xx/XXX_2.0_WCF/WcfJSONRequestsService.svc?wsdl")

次のエラーが表示されます。
