Question

我需要获取cid的值：从阅读时电子邮件正文中包含的图像能够替换cid的值：通过图像的base64，但我无法得到这个价值，有人有任何提示吗？

            try {
       MimeMultipart multipart = (MimeMultipart) msg.getDataHandler().getContent();
       int temp = 0, temp2 = 0;
       for (int k = 0; k < multipart.getCount(); k++) {
          MimeBodyPart bodyPart = (MimeBodyPart) multipart.getBodyPart(k);
          String splited[] = new String[15];
          splited = bodyPart.getContentType().split(" ");

          if (!splited[0].equals("text/plain;") && !splited[0].equals("text/html;")) {
             MimeBodyPart part = bodyPart;
             MimeMultipart p = (MimeMultipart) part.getDataHandler().getContent();
             int count = 0;
             for (int i = 0; i < p.getCount(); i++) {
                String mimeSplited[] = new String[15];
                ByteArrayOutputStream bos = new ByteArrayOutputStream();
                Base64 decoder64 = new Base64();
                StringBuilder s = new StringBuilder(eMail.getCorpoEmail());

                System.out.println("CID NAME" + i + " :" + p.getBodyPart(i).getFileName());
                System.out.println("CID TYPE" + i + " :" + p.getBodyPart(i).getContentType());

                if (i != p.getCount() - 1) {
                   p.getBodyPart(i + 1).getDataHandler().writeTo(bos);
                   mimeSplited = p.getBodyPart(i + 1).getContentType().split(" ");
                   s.insert(s.indexOf(":part" + (i + 1)) - 3, "data:" + mimeSplited[0] + " base64," + decoder64.encodeToString(bos.toByteArray()));
                } else {
                   p.getBodyPart(i).getDataHandler().writeTo(bos);
                   mimeSplited = p.getBodyPart(i).getContentType().split(" ");
                   s.insert(s.indexOf(":part" + i) - 3, "data:" + mimeSplited[0] + " base64," + decoder64.encodeToString(bos.toByteArray()));

                }
                eMail.setCorpoEmail(s.toString());
             }
          } else {
          }

这是我的代码，直到现在。

我的新代码：

            try {
           MimeMultipart multipart = (MimeMultipart) msg.getDataHandler().getContent();
           int temp = 0, temp2 = 0;
           System.out.println("EMAIL BODY ->\n"+eMail.getCorpoEmail());
           for (int k = 0; k < multipart.getCount(); k++) {
              MimeBodyPart bodyPart = (MimeBodyPart) multipart.getBodyPart(k);
              String splited[] = new String[15];
              splited = bodyPart.getContentType().split(" ");

              ByteArrayOutputStream bos = new ByteArrayOutputStream();
              String mimeSplited[] = new String[15];
              Base64 decoder64 = new Base64();
              StringBuilder s = new StringBuilder(eMail.getCorpoEmail());
              String editedBody = "";
              int tempPosition = 0;
              if (bodyPart.getContentType().contains("image/")) {
                 MimeBodyPart part = bodyPart;
                 MimeMultipart p = (MimeMultipart) part.getDataHandler().getContent();

                 //THAT FUNCTION RETURNS NULL EVERY TIME
                 System.out.println("ID -> "+part.getContentID());

                 for (int i = 0; i < p.getCount(); i++) {
                    if (i != p.getCount() - 1) {
                       p.getBodyPart(i + 1).getDataHandler().writeTo(bos);
                       mimeSplited = p.getBodyPart(i + 1).getContentType().split(" ");

                       if (mimeSplited[0].equals("text/html;") || mimeSplited[0].equals("text/plain;")) {
                          s.insert(s.indexOf("src=") + 5, "data:" + "image/png;" + " base64," + decoder64.encodeToString(bos.toByteArray()));

                       } else {
                          s.insert(s.indexOf("src=") + 5, "data:" + mimeSplited[0] + " base64," + decoder64.encodeToString(bos.toByteArray()));

                       }
                       tempPosition = (s.indexOf("src=") + 5) + 23 + decoder64.encodeToString(bos.toByteArray()).length();
                       editedBody = editedBody.concat(s.substring(0, tempPosition));
                       s.delete(0, tempPosition);

                    } else {
                       p.getBodyPart(i).getDataHandler().writeTo(bos);
                       mimeSplited = p.getBodyPart(i).getContentType().split(" ");
//                       s.insert(s.indexOf("src=") + 5, "data:" + mimeSplited[0] + " base64," + decoder64.encodeToString(bos.toByteArray()));
                       tempPosition = (s.indexOf("src=") + 5) + 23 + decoder64.encodeToString(bos.toByteArray()).length();
                       editedBody = editedBody.concat(s.toString());

                 }

Answer 1

您可能希望尝试使用ContentType类来解析ContentType，而不是使用String.split。

可以通过MimeBodyPart.getContentID方法访问每个图像正文部分的Content-ID标头。
