This is my code:
public class GmailService {
/**
* Application name.
*/
private static final String APPLICATION_NAME = "example.com";
private static final String EXAMPLE_EMAIL = "example.com@gmail.com";
/**
* Global instance of the JSON factory.

*/
private static final List<String> SCOPES = new ArrayList<>();
private static final String CREDENTIALS_FILE_PATH = "/credentials.json";
/**
* Creates an authorized Credential object.
*
* @param HTTP_TRANSPORT The network HTTP Transport.
* @return An authorized Credential object.
* @throws IOException If the credentials.json file cannot be found.
*/
private Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
SCOPES.add(GmailScopes.GMAIL_LABELS);
SCOPES.add(GmailScopes.GMAIL_SEND);
SCOPES.add(GmailScopes.MAIL_GOOGLE_COM);
// Load client secrets.
InputStream in = GmailService.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
if (in == null) {
throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
}
final GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
// Build flow and trigger user authorization request.
final GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
.setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
.setAccessType("offline")
.build();
LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8888).build();
Credential credential = new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
//returns an authorized Credential object.
return credential;
}
public boolean sendMessage(String recipientAddress, String subject, String body) throws MessagingException,
IOException, GeneralSecurityException {
Message message = createMessageWithEmail(
createEmail(recipientAddress, EXAMPLE_EMAIL, subject, body));
return createGmail().users()
.messages()
.send(EXAMPLE_EMAIL, message)
.execute()
.getLabelIds().contains("SENT");
}
private MimeMessage createEmail(String to, String from, String subject, String bodyText) throws MessagingException {
MimeMessage email = new MimeMessage(Session.getDefaultInstance(new Properties(), null));
email.setFrom(new InternetAddress(from));
email.addRecipient(javax.mail.Message.RecipientType.TO, new InternetAddress(to));
email.setSubject(subject);
email.setText(bodyText);
return email;
}
private Message createMessageWithEmail(MimeMessage emailContent) throws MessagingException, IOException {
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
emailContent.writeTo(buffer);
return new Message()
.setRaw(Base64.encodeBase64URLSafeString(buffer.toByteArray()));
}
private Gmail createGmail() throws IOException, GeneralSecurityException {
// Build a new authorized API client service.
final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
return new Gmail.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials(HTTP_TRANSPORT))
.setApplicationName(APPLICATION_NAME)
.build();
}
}
What I neet to do?
I use OAuth 2.0 Client IDs credential:
{
"web": {
"client_id": "[REDACTED].googleusercontent.com",
"project_id": "example-3523409",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://oauth2.googleapis.com/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_secret": "[REDACTED]",
"redirect_uris": [
"http://localhost:8888/Callback",
],
"javascript_origins": [
"http://localhost:4200",
"http://localhost:8888",
"http://localhost:8080"
]
}
}
It looks like your post is mostly code; please add some more details.
