While it may not be nearly as kooky as calling Processing on the phone, I’ve been asked about checking e-mail from Processing several times this semester. So rather than try to dig up example code on the internets, I’ve quickly thrown together one that checks a POP account and/or sends mail via SMTP. It’s all done with Javamail.
Code snippets after the jump. . .
Properties props = System.getProperties(); props.put("mail.pop3.host", "pop.gmail.com"); // These are security settings required for gmail // May need different code depending on the account props.put("mail.pop3.port", "995"); props.put("mail.pop3.starttls.enable", "true"); props.setProperty("mail.pop3.socketFactory.fallback", "false"); props.setProperty("mail.pop3.socketFactory.class","javax.net.ssl.SSLSocketFactory"); // Create authentication object Auth auth = new Auth(); // Make a session Session session = Session.getDefaultInstance(props, auth); Store store = session.getStore("pop3"); store.connect(); // Get inbox Folder folder = store.getFolder("INBOX"); folder.open(Folder.READ_ONLY); System.out.println(folder.getMessageCount() + " total messages."); // Get array of messages and display them Message message[] = folder.getMessages(); for (int i=0; i < message.length; i++) { System.out.println("---------------------"); System.out.println("Message # " + (i+1)); System.out.println("From: " + message[i].getFrom()[0]); System.out.println("Subject: " + message[i].getSubject()); System.out.println("Message:"); String content = message[i].getContent().toString(); System.out.println(content); } // Close the session folder.close(false); store.close(); |
and sending:
// Create a session String host="smtp.gmail.com"; Properties props=new Properties(); // SMTP Session props.put("mail.transport.protocol", "smtp"); props.put("mail.smtp.host", host); props.put("mail.smtp.port", "25"); props.put("mail.smtp.auth", "true"); // We need TTLS, which gmail requires props.put("mail.smtp.starttls.enable","true"); // Create a session Session session = Session.getDefaultInstance(props, new Auth()); try { // Make a new message MimeMessage message = new MimeMessage(session); // Who is this message from message.setFrom(new InternetAddress("name@gmail.com", "Name")); // Who is this message to (we could do fancier things like make a list or add CC's) message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("address@email.com", false)); // Subject and body message.setSubject("Hello World!"); message.setText("It's great to be here. . ."); // We can do more here, set the date, the headers, etc. Transport.send(message); println("Mail sent!"); } catch(Exception e) { e.printStackTrace(); } |
