无法打开“ href”链接，其中包含以HTML文件形式作为电子邮件附件发送的屏幕截图-从Java发送邮件

问题描述

我有一个HTML代码，其中包含指向屏幕截图的链接。当我使用Java代码从远程计算机以电子邮件形式发送此HTML文件作为附件（外观）时，附件已成功发送。但是，当我单击屏幕快照链接（从本地计算机打开的附件邮件）时，我在浏览器中收到“找不到文件”消息。我在HTML文件中尝试了以下不同代码，但没有一个能够打开屏幕截图。

HTML文件位置（在远程计算机中-192.145.6.5）：

c:\Java Code\Practice\Report.html

屏幕截图位置（在远程计算机上-192.145.6.5）：

c:\Java Code\Practice\Screenshot\MyPics.png

以下是用于使用Java发送电子邮件的代码

public class SendingEmail {
    public static void main(String[] args) throws IOException {
        File mailReportFolder = new File("Mail Report");
        File fileClientResult = new File(mailReportFolder.getAbsolutePath() + "\\Email Report.txt");
        String clientTextPath = fileClientResult.getAbsolutePath().replaceAll("\\\\","/");
        String emailBodyText = new String(Files.readAllBytes(Paths.get(clientTextPath)));
        
        final String username = "[email protected]";
        final String password = "Password123";
        String fromEmail = "[email protected]";
        String toEmail = "[email protected]";
        
        Properties properties = new Properties();
        properties.put("mail.smtp.auth","true");
        properties.put("mail.smtp.starttls.enable","true");
        properties.put("mail.debug","true");
        properties.put("mail.smtp.host","192.145.40.56");

        // set the port of SMTP server
        properties.put("mail.smtp.port","25");
        
        Session session = Session.getInstance(properties,new javax.mail.Authenticator() {
            protected PasswordAuthentication getpasswordAuthentication() {
                return new PasswordAuthentication(username,password);
            }
        });
        
        MimeMessage msg = new MimeMessage(session);
        try {
            msg.setFrom(new InternetAddress(fromEmail));
            msg.addRecipient(Message.RecipientType.TO,new InternetAddress(toEmail));
            msg.setSubject("Report Checking");
            
            BodyPart messageBodyPart = new MimeBodyPart();
            StringBuilder sb = new StringBuilder();
            sb.append(emailBodyText);
            String message = sb.toString();
            messageBodyPart.setContent(message,"text/html");
            
            Multipart multipart = new MimeMultipart();
            multipart.addBodyPart(messageBodyPart);
            messageBodyPart = new MimeBodyPart();
            String fileName = "C:\\Java Code\\Practice\\Report.html";
            DataSource source = new FileDataSource(fileName);
            messageBodyPart.setDataHandler(new DataHandler(source));
            messageBodyPart.setFileName(fileName);
            multipart.addBodyPart(messageBodyPart);
            msg.setContent(multipart);
            
            Transport.send(msg);
            System.out.println("Message Sent");
        } catch (MessagingException e) {
            e.printstacktrace();
        }
    }
}

请告知我是否需要从头到尾进行任何处理。谢谢
