javax.mail.AuthenticationFailedException: [AUTH] 需要 Web 登录
javax.mail.AuthenticationFailedException: [AUTH] Web login required
我使用 Java 构建了一个应用程序来阅读电子邮件。它过去几天没有任何错误地工作。但是今天突然出现这样的错误
javax.mail.AuthenticationFailedException: [AUTH] Web login required: https://support.google.com/mail/answer/78754
at com.sun.mail.pop3.POP3Store.protocolConnect(POP3Store.java:207)

我不知道如何解决这个问题。我没有进行双向身份验证。而且我还允许使用不太安全的应用程序。所以我不知道出了什么问题。任何人都可以帮助我吗?非常感谢。
这是我使用的代码,
String host = "pop.gmail.com";
String username = "somename@gmail.com";
String password = "password";
Properties prop = new Properties();
Session session = Session.getInstance(prop, null);
Store store = session.getStore("pop3s");
store.connect(host, username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
我的工作片段如下所示:
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.NoSuchProviderException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Store;
public class CheckingMails {
public static void check(String host, String user, String password)
{
try {
// create properties field
Properties properties = new Properties();
properties.put("mail.pop3s.host", host);
properties.put("mail.pop3s.port", "995");
properties.put("mail.pop3s.starttls.enable", "true");
// Setup authentication, get session
Session session = Session.getInstance(properties,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
});
// session.setDebug(true);
// create the POP3 store object and connect with the pop server
Store store = session.getStore("pop3s");
store.connect();
// create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_ONLY);
// retrieve the messages from the folder in an array and print it
Message[] messages = emailFolder.getMessages();
System.out.println("messages.length---" + messages.length);
for (int i = 0, n = messages.length; i < n; i++) {
Message message = messages[i];
System.out.println("---------------------------------");
System.out.println("Email Number " + (i + 1));
System.out.println("Subject: " + message.getSubject());
System.out.println("From: " + message.getFrom()[0]);
System.out.println("Text: " + message.getContent().toString());
}
// close the store and folder objects
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
String host = "pop.gmail.com";
String username = "abc@gmail.com";// change accordingly
String password = "*****";// change accordingly
check(host, username, password);
}
}
错误是由于 Google 处的错误导致 POP3 服务无法正常工作。 2天后修复。
我的问题是相同的代码在本地运行但在远程云(Bitbucket 管道)上不起作用,尽管我设置了不太安全的启用。我通过启用两步验证并创建应用密码解决了这个问题。然后在代码中使用这个应用密码代替普通密码。
