使用带有accountmanager令牌的imap访问gmail

我正在尝试使用从Android的AccountManager收到的令牌而不是使用用户名和密码来实现IMAP gmail客户端。

Google通过oauth2提供了此IMAP示例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  "); 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时，我得到“空用户名或密码”的例外。 有人可以告诉我如何使用带有xoauth2的imap访问gmail吗？ 谢谢。

我使用yor mail.jar和我的应用程序无法创建SASL客户端：myjavax.security.sasl.SaslException：无法实例化类com.research.oauth.OAuth2SaslClientFactory ，然后app使用空密码登录gmail。 请帮我弄清楚问题，谢谢！

您是否记得在OAuth2Provider中更改您的包名？ 当我使用该代码进行测试时，我忘了它。 

 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中所说，我只测试了连接，但它对我有用。

UPDATE

这是我使用的代码，它基本上是示例代码，它真正改变了Java Mail中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"); } }

}

这是Java Mail的调试。 顺便说一句，发布你的调试日志，它应该有助于解决出错的问题

我做了什么来解决相同的问题来重新编译java邮件包的源代码，在IMAPSaslAuthenticator文件中将javax.security的调用替换为asmack。 IMAP连接可以通过，

我下载了包

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

我没有使用包裹

  1. 的mail.jar
  2. additionnal.jar

如果我在main方法中运行testcode，这对我有用，但是在glassfish服务器上部署它我会遇到其他问题。 遵循http://code.google.com/p/google-mail-oauth2-tools/中的代码

下面的这个例外是触发的，我开始认为这与错误或其他问题有关，但无法找出原因。 Callback是否需要在Google API控制台中使用一些ULR？ 或者为什么它在本地工作，而不是在glassfish部署时。 java.lang.IllegalStateException：WEB9031：WebappClassLoader无法加载资源[com.google.code.samples.oauth2.OAuth2SaslClientFactory]，因为它尚未启动或已停止

另请查看此错误是否与此相关： https ： //groups.google.com/forum/#！msg / google -appengine / OK3FuIPuA1I / dgov_VRffVgJ
