Question

您好我被困在我下面提到的代码中，问题是，从缓冲区我无法获取网址。我的议程是将URL格式化为邮件（用户收到邮件进行注册，邮件中存在一个URL以激活帐户）。

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStreamReader;
import java.util.Properties;

import javax.mail.Flags;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Store;
import javax.mail.search.SubjectTerm;

public class javamailtest {

    public static void main(String[] args) {
        javamailtest gmail = new javamailtest();
        gmail.read();
    }



    public void read() {

        Properties props = new Properties();
        try {
            props.load(new FileInputStream(new File("D:\\smtp.properties")));
            Session session = Session.getDefaultInstance(props, null);

            Store store = session.getStore("imaps");
            store.connect("smtp.gmail.com", "dummy@dummy.com","dummy_password");

            Folder inbox = store.getFolder("inbox");
            inbox.open(Folder.READ_ONLY);
            int messageCount = inbox.getMessageCount();

            System.out.println("Total Messages:- " + messageCount);

            /*
             * Message[] messages = inbox.getMessages();
             * System.out.println("------------------------------"); for (int i
             * = 0; i < 10; i++) { System.out.println("Mail Subject:- " +
             * messages[i].getSubject()); }
             */

            Message[] messages2;
            messages2 = inbox.search(new SubjectTerm("hello avinash test"),inbox.getMessages());

            System.out.println(messages2.length);
            for (int k = 0; k < messages2.length; k++) {
                System.out.println(messages2[k].getSubject());
                System.out.println(messages2[k].getContent().toString());
            }

            for (Message mail : messages2) {
                if (!mail.isSet(Flags.Flag.SEEN)) {
                    // it's Working here

                            new InputStreamReader(mail.getInputStream()));
                    // this function is also working and returning 12 lines
                    while ((line = reader.readLine()) != null) {
                        buffer.append(line);

                    System.out.println("buffer content is" +buffer + buffer.length());

                    //System.out.println("Message Count is: "+ mail.getDescription());
                    // System.out.println("Message Count is: "+
                    // mail.getSubject());

                    try {

                        /*System.out.println("String values are:- "+eTest);
                        int len = eTest.length();
                        System.out.println("String length is:- "+len);*/

                        }*/

首先，您不了解邮件消息的结构。您可能希望从此JavaMail FAQ entry to find the main text content of your message开始。一旦你有了文本内容，就像其他人所说的那样，它只是一个字符串解析问题。
