【问题描述】:
我正在使用 javamail 发送 html 和图像,但由于某种原因,我没有将图像视为 html 的一部分,我仅将它们视为附件。我不知道为什么会这样。这是我的一个用户收到电子邮件时的样子:
我还想提一下 html 的样子:
private String generateActivationLinkTemplate() {
String htmlText = "";
htmlText ="<table width=\"600\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\"> <tr> <td><img src=\"cid:logoimg\"/></td> </tr> <tr> <td height=\"220\"> <p>Thanks for Joining Site.com</p> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. </p> <p>Username:<br /> Password: </p> <p>To confirm your email click <a href=\"#\">here</a>.</p></td> </tr> <tr> <td height=\"50\" align=\"center\" valign=\"middle\" bgcolor=\"#CCCCCC\">www.site.com | contact@site.com | +38200 123 456</td> </tr></table>";}
我需要 html、body 和 head 标签吗?
这是java实现的样子:
@Stateless(name = "ejbs/EmailServiceEJB")
public class EmailServiceEJB implements IEmailServiceEJB {
@Resource(name = "mail/myMailSession")
private Session mailSession;
public void sendAccountActivationLinkToBuyer(String destinationEmail,
String name) {
// Destination of the email
String to = destinationEmail;
String from = "dontreply2thismessage@gmail.com";
try {
Message message = new MimeMessage(mailSession);
// From: is our service
message.setFrom(new InternetAddress(from));
// To: destination given
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject("Uspijesna registracija");
// How to found at http://www.rgagnon.com/javadetails/java-0321.html
message.setContent(generateActivationLinkTemplate(), "text/html");
Date timeStamp = new Date();
message.setSentDate(timeStamp);
// Prepare a multipart HTML
Multipart multipart = new MimeMultipart();
// Prepare the HTML
BodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(generateActivationLinkTemplate(), "text/html");
// PREPARE THE IMAGE
BodyPart imgPart = new MimeBodyPart();
String fileName = "logoemailtemplate.png";
ClassLoader classLoader = Thread.currentThread()
.getContextClassLoader();
if (classLoader == null) {
classLoader = this.getClass().getClassLoader();
if (classLoader == null) {
System.out.println("IT IS NULL AGAIN!!!!");
}
}
DataSource ds = new URLDataSource(classLoader.getResource(fileName));
imgPart.setDataHandler(new DataHandler(ds));
imgPart.setHeader("Content-ID", "logoimg");
multipart.addBodyPart(imgPart);
multipart.addBodyPart(htmlPart);
// Set the message content!
message.setContent(multipart);
Transport.send(message);
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
我认为 java 部分对我来说看起来不错,但我怀疑只是 html 标记,我有什么问题吗?我认为 img 标签无法正常工作,并且图像没有出现在电子邮件中(注意它只显示为附件):
<img src=\"cid:logoimg\"/>
【问题讨论】:
-
你能发布生成的 MIME 代码,或者至少是标题可见但内容被修剪的 MIME 代码吗?
-
能否请您告诉我如何查找或生成 MIME 代码,以便我发布。我有点困惑。
-
我唯一改变的是这个 imgPart.setHeader("Content-ID", "
");现在完美运行。
