Obsługa TLS 1.2 i AutodiscoverService

Aspose.Email for Java obsługuje teraz TLS 1.2 przy użyciu API SAAJ.  EWSClient udostępnia właściwość statyczną useSAAJAPI co może być ustawione na true w celu używania TLS 1.2. Aspose.Email for Java obsługuje również AutodiscoverService dla TLS 1.2. Poniższe przykłady kodu demonstrują użycie API SAAJ oraz AutodiscoverService dla TLS 1.2.

Użyj API SAAJ

Klient Java EE SOAP używany w trybie SAAJAPI - https://docs.oracle.com/cd/E19651-01/817-2151-10/wsgjaxm.html.

Poniższy przykład kodu demonstruje użycie API SAAJ poprzez ustawienie EWSClient.useSAAJAPI właściwość na true.

W następnym fragmencie kodu zostanie przypisany nagłówek uwierzytelniania Basic:

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

W następnym fragmencie kodu zostanie przypisany nagłówek uwierzytelniania OAUTH2:

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();

Fragment kodu uwierzytelniania NTLM dla Javy 8:

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"));

Od Javy 9, Authenticator może być ustawiony dla połączenia:

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"));

Użyj AutodiscoverService

Poniższy przykład kodu demonstruje użycie AutodiscoverService dla TLS 1.2

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