私は、静的ファイルのコンテンツを読み取る必要があるGoogle App Engine Javaでアプリを作成しています.warディレクトリに myrsakey11.pk8 という名前のファイルがあります。
ファイルを読み取るための私のコードセグメントは
public static PrivateKey getPrivateKey(String privKeyFileName) throws IOException {
File privKeyFile = new File(privKeyFileName);
FileInputStream fis = new FileInputStream(privKeyFile);
DataInputStream dis = new DataInputStream(fis);
byte[] privKeyBytes = new byte[(int) privKeyFile.length()];
try {
dis.read(privKeyBytes);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
dis.close();
fis.close();
String BEGIN = "-----BEGIN PRIVATE KEY-----";
String END = "-----END PRIVATE KEY-----";
String str = new String(privKeyBytes);
if (str.contains(BEGIN) && str.contains(END)) {
str = str.substring(BEGIN.length(), str.lastIndexOf(END));
}
KeyFactory fac;
try {
fac = KeyFactory.getInstance("RSA");
EncodedKeySpec privKeySpec = new PKCS8EncodedKeySpec(Base64.decode(str));
return fac.generatePrivate(privKeySpec);
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Base64DecoderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvalidKeySpecException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
この関数では、文字列「/myrsakey11.pk8」を渡しています
そして、私が取得している完全なエラーログは
