Использование javax.mail с Microsoft OAuth
Поскольку Microsoft объявила, что собирается отказаться от аутентификации по паролю для своих SMTP-сервисов. Я пытаюсь заменить аутентификацию пароля наjavax.mailс OAuth. Однако я получаю исключение с сообщением535 5.7.3 Authentication unsuccessful [MN2PR04CA0023.namprd04.prod.outlook.com].
Мой фрагмент кода выглядит сейчас так:
/**
* Class for sending email notifications.
*/
public class MailClient {
/**
* Send email (SMTP)
*
* @param params Runtime Parameters
* @param durationString Formatted duration
* @param endTime Time at which the task completed
* @param totalJournals Number of Journals read
* @param totalLines Number of Journal Lines Written
* @param outputFileStored Was output file stored?
* @param refFileStored Was Org Ref file stored?
* @param checkpointStored Was timestamp checkpoint stored?
* @param errorFile Location of error file (null if no errors)
* @throws Exception
*/
public static void send(ArgParse params, String durationString, ZonedDateTime endTime, int totalJournals,
int totalLines, Boolean outputFileStored, Boolean refFileStored, Boolean checkpointStored, String errorFile)
throws Exception {
Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", params.smtpHost);

// Old password auth
/*Session session = Session.getDefaultInstance(properties, new javax.mail.Authenticator() {

});*/
Session session = Session.getDefaultInstance(properties);
Multipart multipart = new MimeMultipart();
MimeMessage message = new MimeMessage(session);
MimeBodyPart messageBodyPart;
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
String endTimeString = endTime.format(formatter), endDateString = endTimeString.split("T")[0];
String subject = "secure: Journal-DataWarehouse run [" + endDateString + "]", body = "<html>";
message.setFrom(new InternetAddress(params.mailFrom));
for(int i = 0; i < params.mailTo.length; i++)
message.addRecipient(Message.RecipientType.TO, new InternetAddress(params.mailTo[i]));
message.addHeader("Date", endTime.format(DateTimeFormatter.RFC_1123_DATE_TIME));
message.setSubject(subject);
if(errorFile != null) {
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(errorFile);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName("error_logs.txt");
multipart.addBodyPart(messageBodyPart);

}

body += "</html>";
messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(body, "text/html");
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
// Fetch OAuth token and send message. (New code)
MicrosoftAuth auth = new MicrosoftAuth();
String authToken = auth.getAccessToken();
SMTPTransport transport = new SMTPTransport(session, null);
transport.connect(params.smtpHost, params.username, null);
transport.issueCommand("AUTH XOAUTH2 " + new String(BASE64EncoderStream.encode(String.format("user=%s\1auth=Bearer %s\1\1", params.username, authToken).getBytes())), 235);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
}
The MicrosoftAuthкласс используетmsal4j.ConfidentialClientApplicationдля получения токена аутентификации с использованием идентификатора клиента и секрета клиента.
