รองรับ TLS 1.2 และ AutodiscoverService
Aspose.Email for Java ตอนนี้รองรับ TLS 1.2 ด้วยการใช้ SAAJ API. ส่วน EWSClient ให้คุณสมบัติสแตติก useSAAJAPI ซึ่งสามารถตั้งค่าเป็น true เพื่อใช้ TLS 1.2 Aspose.Email for Java ยังสนับสนุน AutodiscoverService สำหรับ TLS 1.2 ตัวอย่างโค้ดต่อไปนี้แสดงการใช้ SAAJ API และ AutodiscoverService สำหรับ TLS 1.2.
ใช้ SAAJ API
คลายเอนต์ Java EE SOAP ที่ใช้ในโหมด SAAJAPI - https://docs.oracle.com/cd/E19651-01/817-2151-10/wsgjaxm.html.
ตัวอย่างโค้ดต่อไปนี้แสดงการใช้ SAAJ API โดยตั้งค่า EWSClient.useSAAJAPI คุณสมบัติเป็น true.
ในโค้ดสแนปต่อไปจะกำหนดหัวข้อการตรวจสอบสิทธิ Basic:
EWSClient.useSAAJAPI(true);
IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "testuser", "pw", "domain");
client.listMessages();
ในโค้ดสแนปต่อไปจะกำหนดหัวข้อการตรวจสอบสิทธิ 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();
โค้ดสแนปการตรวจสอบสิทธิ NTLM สำหรับ Java 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"));
ตั้งแต่ Java 9 เป็นต้นไป Authenticator สามารถตั้งค่าสำหรับการเชื่อมต่อได้:
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"));

ใช้ AutodiscoverService
ตัวอย่างโค้ดต่อไปนี้แสดงการใช้ AutodiscoverService สำหรับ TLS 1.2
AutodiscoverService service = new AutodiscoverService();
service.setCredentials(new NetworkCredential("user", "password"));
GetUserSettingsResponse response = service.getUserSettings("userSmtpAddress", UserSettingName.ExternalEwsUrl, UserSettingName.UserDisplayName);
