TLS 1.2 ve AutodiscoverService Desteği

Aspose.Email for Java artık SAAJ API kullanarak TLS 1.2’yi desteklemektedir.  EWSClient statik bir özellik sağlar useSAAJAPI TLS 1.2 kullanımı için true olarak ayarlanabilir. Aspose.Email for Java ayrıca destekler AutodiscoverService TLS 1.2 için. Aşağıdaki kod örnekleri SAAJ API’sinin kullanımını ve AutodiscoverService TLS 1.2 için.

SAAJ API’sini Kullan

SAAJAPI modunda kullanılan Java EE SOAP İstemcisi - https://docs.oracle.com/cd/E19651-01/817-2151-10/wsgjaxm.html.

Aşağıdaki kod örneği, SAAJ API’sini ayarlayarak nasıl kullanılacağını gösterir. EWSClient.useSAAJAPI özelliği true olarak.

Sonraki kod parçacığında Basic kimlik doğrulama başlığı atanacaktır:

EWSClient.useSAAJAPI(true);
IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "testuser", "pw", "domain");
client.listMessages();

Sonraki kod parçacığında OAUTH2 kimlik doğrulama başlığı atanacaktır:

EWSClient.useSAAJAPI(true);
// token provider
/*ITokenProvider provider = new ITokenProvider() {

    @Override
    public void dispose() {
    }

    @Override
    public OAuthToken getAccessToken(boolean ignoreExistingToken) {
        return null;
    }

    @Override
    public OAuthToken getAccessToken() {
        return null;
    }
};

NetworkCredential credentials = new OAuthNetworkCredential(provider);*/

// accessToken
NetworkCredential credentials = new OAuthNetworkCredential("accessToken");

IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", credentials);
client.listMessages();

Java 8 için NTLM kimlik doğrulama kod parçacığı:

import java.net.Authenticator;
import java.net.PasswordAuthentication;
import java.net.URL;

static Authenticator getAuthenticator(String user, String pw, String domain) {
    final String username = domain + "\\" + user;
    final String password = pw;
    System.out.println("New Credentials " + username);
    return new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            System.out.println("Authenticate " + username);
            return new PasswordAuthentication(username, password.toCharArray());
        }
    };
}

EWSClient.useSAAJAPI(true);
System.setProperty("http.auth.preference", "NTLM");
Authenticator.setDefault(getAuthenticator("user", "pw", ""));
IEWSClient client = EWSClient.getEWSClient(new URL("https://domain.com/ews/Exchange.asmx"));

static Authenticator getAuthenticator() {

    // This block is written for suppressing a bug in sun implementation.
    // In Sun Impl client doesn't authenticate user for each connection,
    // uses cached credentials instead.
    sun.net.www.protocol.http.AuthCacheValue.setAuthCache(new sun.net.www.protocol.http.AuthCache() {
        public void remove(String pkey, sun.net.www.protocol.http.AuthCacheValue entry) {
        }
        public void put(String pkey, sun.net.www.protocol.http.AuthCacheValue value) {
        }
        public sun.net.www.protocol.http.AuthCacheValue get(String pkey, String skey) {
            return null;
        }
    });

    return new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return getEmbeddedCredentials(getRequestingURL());
        }

        PasswordAuthentication getEmbeddedCredentials(URL url) {
            if (url == null) {
                return null;
            }
            String userInfo = url.getUserInfo();
            int colon = userInfo == null ? -1 : userInfo.indexOf(":");
            if (colon == -1) {
                return null;
            } else {
                String userName = userInfo.substring(0, colon);
                String pass;
                try {
                    pass = URLDecoder.decode(userInfo.substring(colon + 1), "UTF-8");
                } catch (UnsupportedEncodingException e) {
                    pass = "";
                }
                System.out.println("Authenticate " + userInfo);
                return new PasswordAuthentication("\\" + userName, pass.toCharArray());
            }
        }
    };
}

static URL getURL(String url, String user, String pw, String domain) throws Exception {
    String host = new URL(url).getHost();
    URL endpoint = new URL(url.replace(host, user + ":" + URLEncoder.encode(pw, "UTF-8") + "@" + host));

    return endpoint;
}

EWSClient.useSAAJAPI(true);
Authenticator.setDefault(getAuthenticator());

System.setProperty("http.auth.preference", "NTLM");
IEWSClient client1 = EWSClient.getEWSClient(getURL("https://domain.com/ews/Exchange.asmx", "user1", "pw", "domain"));
IEWSClient client2 = EWSClient.getEWSClient(getURL("https://domain.com/ews/Exchange.asmx", "user2", "pw", "domain"));

Java 9’dan itibaren Authenticator, bağlantı için ayarlanabilir:

static Map<String, Authenticator> authInfo = new HashMap<String, Authenticator>();
static URL getURL(String url, final String user, final String pw, final String domain) throws MalformedURLException {
    URL endpoint = new URL(new URL(url), "", new URLStreamHandler() {
        protected URLConnection openConnection(URL url) throws IOException {
            URL target = new URL(url.toString());
            HttpURLConnection connection = (HttpURLConnection) target.openConnection();
            // Cache for User@Url
            Authenticator auth = authInfo.get(user + "@" + url);
            if (auth == null) {
                auth = new Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        System.out.println("Authenticate " + user);
                        return new PasswordAuthentication(domain + "\\" + user, pw.toCharArray());
                    }
                };
                authInfo.put(user + "@" + url, auth);
            }
            connection.setAuthenticator(auth);

            return connection;
        }
    });

    return endpoint;
}

EWSClient.useSAAJAPI(true);
System.setProperty("http.auth.preference", "NTLM");
IEWSClient client1 = EWSClient.getEWSClient(getURL("https://domain.com/ews/Exchange.asmx", "user1", "pw", "domain"));
IEWSClient client2 = EWSClient.getEWSClient(getURL("https://domain.com/ews/Exchange.asmx", "user2", "pw", "domain"));

AutodiscoverService’i Kullan

Aşağıdaki kod örneği kullanımını gösterir AutodiscoverService TLS 1.2 için

AutodiscoverService service = new AutodiscoverService();
service.setCredentials(new NetworkCredential("user", "password"));
GetUserSettingsResponse response = service.getUserSettings("userSmtpAddress", UserSettingName.ExternalEwsUrl, UserSettingName.UserDisplayName);
