IMAPを使用してJavaMailを使用してgmailに接続しようとしています
これが私がやっていることのコードスニペットです
public class OAuth2Authenticator {
private static final Logger logger = Logger
.getLogger(OAuth2Authenticator.class.getName());
private static Session mSession;
public static final class OAuth2Provider extends Provider {
private static final long serialVersionUID = 1L;
public OAuth2Provider() {
super("Google OAuth2 Provider", 1.0,
"Provides the XOAUTH2 SASL Mechanism");
put("SaslClientFactory.XOAUTH2",
"org.scribe.examples.OAuth2SaslClientFactory");
}
}
public static void initialize() {
Security.addProvider(new OAuth2Provider());
}
public static IMAPStore connectToImap(String host, int port,
String userEmail, String oauthToken, boolean debug)
throws Exception {
Properties props = new Properties();
props.put("mail.imaps.sasl.enable", "true");
props.put("mail.imaps.sasl.mechanisms", "XOAUTH2");
props.put(OAuth2SaslClientFactory.OAUTH_TOKEN_PROP, oauthToken);
Session session = Session.getInstance(props);
session.setDebug(debug);
final URLName unusedUrlName = null;
IMAPSSLStore store = new IMAPSSLStore(session, unusedUrlName);
final String emptyPassword = "";
store.connect(host, port, userEmail, emptyPassword);
return store;
}
public static synchronized void testImap(String user, String oauthToken) {
try {
initialize();
IMAPStore imapStore = connectToImap("imap.gmail.com", 993, user,
oauthToken, true);
} catch (Exception e) {
System.out.println("Failed");
e.printStackTrace();
}
}
public static void main (String[] args){
String username="username@gmail.com";
String oauthToken=GoogleExample.getOAuthCode();// explained below
testImap(username, oauthToken);
}
}
OauthTokenを取得するために、私はこのようなスクライブを使用しています
private static final String NETWORK_NAME = "Google";
private static final String AUTHORIZE_URL = "https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token=";
private static final String PROTECTED_RESOURCE_URL = "https://mail.google.com/mail/feed/atom";
private static final String SCOPE = "https://mail.google.com/mail";
public static String getOAuthCode(){
OAuthService service = new ServiceBuilder()
.provider(GoogleApi.class)
.apiKey("anonymous")
.apiSecret("anonymous")
.scope(SCOPE)
.build();
Scanner in =new Scanner(System.in);
System.out.println("=== " + NETWORK_NAME + "'s OAuth Workflow ===");
System.out.println();
//Obtain Request token
System.out.println("Fetching request token");
Token requestToken = service.getRequestToken();
System.out.println("The request token"+requestToken);
System.out.println("Authorizing Scribe");
System.out.println();
System.out.println(AUTHORIZE_URL + requestToken.getToken());
System.out.println("And paste the verifier here");
System.out.print(">>");
Verifier verifier = new Verifier(in.nextLine());
System.out.println();
System.out.println("Trading the Request Token for an Access Token...");
Token accessToken = service.getAccessToken(requestToken, verifier);
System.out.println("Got the Access Token!");
System.out.println("(if your curious it looks like this: " + accessToken + " )");
System.out.println();
return accessToken.getToken();
}
これは、プログラムを実行したときに得られるもののデバッグログです
