我试图实现使用来自Android的的AccountManager接受，而不是使用用户名和密码的令牌的IMAP Gmail客户端。

谷歌提供IMAP的这个例子用的oauth2 http://code.google.com/p/google-mail-oauth2-tools/source/browse/#svn%2Ftrunk%2Fjava%2Fcom%2Fgoogle%2Fcode%2Fsamples%2Foauth2 HTTP： //code.google.com/p/google-mail-oauth2-tools/wiki/JavaSampleCode

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 void main(String args[]) throws Exception {
if (args.length != 2) {
  System.err.println(
      "Usage: OAuth2Authenticator <email> <oauthToken>");
  return;
}
String email = args[0];
String oauthToken = args[1];

initialize();

IMAPStore imapStore = connectToImap("imap.gmail.com",
                                    993,
                                    email,
                                    oauthToken,
                                    true);
System.out.println("Successfully authenticated to IMAP.\n");

}

但是，当我运行上面的代码，我得到“空用户名或密码”的一个例外。有人能告诉我如何使用IMAP与xoauth2访问Gmail？谢谢。

更新2013年2月20日，下面来调试日志

我用侑的mail.jar和我的应用程序无法创建SASL客户端：myjavax.security.sasl.SaslException：无法实例类com.research.oauth.OAuth2SaslClientFactory，然后应用程序使用空密码登录的Gmail。请帮我找出问题，谢谢！

Answer 1:

你记住在OAuth2Provider改变你的包叫什么名字？我忘了，当我在做与该代码的测试。

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",
      "com.example.testjavamail.OAuth2SaslClientFactory");
}

}

正如我在另一个答案说，我只测试了连接，但它为我工作。

UPDATE

下面是我使用的代码，它基本上示例代码，真正改变了在Java邮件SASL支持的移植。

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",
                "com.example.testjavamail.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 SMTPTransport connectToSmtp(String host, int port,
        String userEmail, String oauthToken, boolean debug)
        throws Exception {
    Properties props = new Properties();
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.starttls.required", "true");
    props.put("mail.smtp.sasl.enable", "true");
    props.put("mail.smtp.sasl.mechanisms", "XOAUTH2");
    props.put(OAuth2SaslClientFactory.OAUTH_TOKEN_PROP, oauthToken);
    mSession = Session.getInstance(props);
    mSession.setDebug(debug);

    final URLName unusedUrlName = null;
    SMTPTransport transport = new SMTPTransport(mSession, unusedUrlName);
    // If the password is non-null, SMTP tries to do AUTH LOGIN.
    final String emptyPassword = null;
    transport.connect(host, port, userEmail, emptyPassword);

    return transport;
}

public synchronized void testImap(String user, String oauthToken) {
    try {

        initialize();


        IMAPStore imapStore = connectToImap("imap.gmail.com", 993, user,
                oauthToken, true);

    } catch (Exception e) {
        Log.d("test", e.toString());
    }

}

public class ByteArrayDataSource implements DataSource {
    private byte[] data;
    private String type;

    public ByteArrayDataSource(byte[] data, String type) {
        super();
        this.data = data;
        this.type = type;
    }

    public ByteArrayDataSource(byte[] data) {
        super();
        this.data = data;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getContentType() {
        if (type == null)
            return "application/octet-stream";
        else
            return type;
    }

    public InputStream getInputStream() throws IOException {
        return new ByteArrayInputStream(data);
    }

    public String getName() {
        return "ByteArrayDataSource";
    }

    public OutputStream getOutputStream() throws IOException {
        throw new IOException("Not Supported");
    }
}

}

下面是从Java邮件调试。顺便说一句，发布您的调试日志，它应该在undertanding什么错帮助

我所做的解决同样的问题，重新编译Java邮件包的源，取代javax.security的呼叫在IMAPSaslAuthenticator文件asmack。在IMAP连接可以顺利通过，

我下载的软件包

JavaMail的-1.5.0-SRC
asmack-Android的8-0.8.9.jar
的activation.jar

我没有用的包

的mail.jar
additionnal.jar

Answer 3:

这个工作对我来说，如果我运行main方法的testcode，但GlassFish服务器我有其他问题上部署此。下面从代码http://code.google.com/p/google-mail-oauth2-tools/

下面这个异常被触发，然后，我开始认为这是关系到一个错误或其它问题，但无法找出原因。是回调需要一些ULR在谷歌API控制台？或者为什么当在GlassFish中部署它在本地，但无法正常工作。 java.lang.IllegalStateException：WEB9031：WebappClassLoader无法加载资源[com.google.code.samples.oauth2.OAuth2SaslClientFactory]，因为它尚未启动，或者已经停止

又看了如果这个错误是与此有关： https://groups.google.com/forum/#!msg/google-appengine/OK3FuIPuA1I/dgov_VRffVgJ
