如何将HTML链接放入电子邮件正文内？ [英] How Can I put a HTML link Inside an email body?

问题描述

我有一个应用程序可以发送邮件，在Java中实现。我想把一个HTML链接放在邮件中，但链接显示为普通字母，而不是HTML链接...
我该如何做到HTML链接到一个String？我需要特殊字符？非常感谢你

更新：
HI evereybody！谢谢你的答案！这是我的代码：

  public static boolean sendMail（Properties props，String to，String from，
 String password， String subject，String body）
 {
 try 
 {
 MimeBodyPart mbp = new MimeBodyPart（）; 
 mbp.setContent（body，text / html）; 
 MimeMultipart multipart = new MimeMultipart（）; 
 multipart.addBodyPart（mbp）; 
 
 
 
 // Preparamos la sesion 
会话session = Session.getDefaultInstance（props）; 
 
 // Construimos el mensaje 
 MimeMessage message = new MimeMessage（session）; 
 message.setFrom（new InternetAddress（from））; 
 message.setContent（multipart）; 
 message.addRecipient（
 Message.RecipientType.TO，
 new InternetAddress（to））; 
 message.setSubject（subject）; 
 message.setText（body）; 
 
 // Lo enviamos。 
传输t = session.getTransport（smtp）; 
 t.connect（from，password）; 
 t.sendMessage（message，message.getAllRecipients（））; 
 
 // Cierre。 
 t.close（）; 
返回true; 
} 
 catch（异常e）
 {
 e.printStackTrace（）; 
返回false; 
} 
} 
  

这里的主体字符串：

  String link =< a href = \WWW.google.es\> ACTIVAR CUENTA< / a>; 
  

但是在收到的消息中，链接显示为链接字符串，而不是HTML超链接！我不明白会发生什么...

任何解决方案？

解决方案

添加链接与在字符串中添加< a href =..> text< / a> 一样简单。您应该将您的电子邮件设置为支持html（这取决于您使用的库），您不应该在发送邮件之前转出您的电子邮件内容。

更新：自从你正在使用 java.mail ，您应该以这种方式设置文本：

  message.setText（body，UTF-8，html）; 
  

html 是mime子类型导致 text / html ）。 setText（string）方法使用的默认值为 plain

I have an application thats can send mails, implemented in Java. I want to put a HTML link inside de mail, but the link appears as normal letters, not as HTML link... How can i do to inside the HTML link into a String? I need special characters? thank you so much

Update: HI evereybody! thanks for oyu answers! Here is my code:

public static boolean sendMail(Properties props, String to, String from,
          String password, String subject, String body)
{
    try
    {
        MimeBodyPart mbp = new MimeBodyPart(); 
        mbp.setContent(body, "text/html"); 
        MimeMultipart multipart = new MimeMultipart(); 
        multipart.addBodyPart(mbp); 



        // Preparamos la sesion
        Session session = Session.getDefaultInstance(props);

        // Construimos el mensaje
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.setContent(multipart);
        message.addRecipient(
                Message.RecipientType.TO,
                new InternetAddress(to));
        message.setSubject(subject);
        message.setText(body);

        // Lo enviamos.
        Transport t = session.getTransport("smtp");
        t.connect(from, password);
        t.sendMessage(message, message.getAllRecipients());

        // Cierre.
        t.close();
        return true;
    }
    catch (Exception e)
    {
        e.printStackTrace();
        return false;
    }
}

And here the body String:

        String link = "<a href=\"WWW.google.es\">ACTIVAR CUENTA</a>";

But in the received message the link appears as the link string, not as HTML hyperlink! I don't understand what happens...

Any solution?

解决方案

Adding the link is as simple as adding the <a href="..">text</a> inside the string. You should set your email to support html (it depends on the library you are using), and you should not escape your email content before sending it.

Update: since you are using java.mail, you should set the text this way:

message.setText(body, "UTF-8", "html");

html is the mime subtype (this will result in text/html). The default value that is used by the setText(string) method is plain
