ConfigParserとUnicode

Pythonには、 ConfigParserと呼ばれるiniのような構成ファイルを保存および読み取るための非常に便利なモジュールがあります。



それを使用するときに、Unicode文字列をファイルに保存することに関連する問題がありました。 いくつかの微妙な場合（たとえば、アプリケーションがWindows XPで実行されているときに表示されます）、そのようなパラメーターを読み書きすると、文字列変換エラーが表示されます。



インターネットで既製のソリューションを見つけることができませんでしたが、「常に機能させる方法」については非常に多くの質問があります。通常、「モジュールの作成者に修正を依頼する」という精神で答えます。



Python 2.Xを使用している人にソリューションを提供したい-それは非常に簡単で、この問題の解決に役立ちます。







最初に、 write（）メソッドをオーバーライドして、 RawConfigParserクラスを継承する必要があります。つまり、すべてのstr（）呼び出しをunicode（）呼び出しに置き換えます。

次に、構成ファイルの書き込みと読み取りは、 コーデックモジュールのopen（）のラッパーを使用して実行する必要があります。これは、エンコードとしてutf-8で指定する必要があります。 ロードの場合、 読み取りにread（）ではなくreadfp（）を使用すると、これを実行できます。



Copy Source | Copy HTML



  1. コーデックをインポートする
  3. ＃保存
  5. confFile = codecs 。 オープン （ 'myConfig.ini' 、 'w' 、 'utf-8' ）
  6. config = UnicodeConfigParser（）
  7. ＃...
  8. config.write（confFile）
  9. confFile.close（）
  11. ＃読み込み中
  13. config = UnicodeConfigParser（）
  14. config.readfp（codecs。open（ 'myConfig.ini' 、 "r" 、 "utf-8" ））
