我出口MIME电子邮件,其中包含下面的代码:如何在MIME导出中避免多余的换行符?
public String fromRawMime(final Session s, final Document doc) throws NotesException {
final Stream notesStream = s.createStream();
final MIMEEntity rootMime = doc.getMIMEEntity();
// check if it is multi-part or single
if (rootMime.getContentType().equals("multipart")) {
this.printMIME(rootMime, notesStream);
} else {
// We can just write the content into the
// Notes stream to get the bytes
rootMime.getEntityAsText(notesStream);
}
// Write it out
notesStream.setPosition(0);
ByteArrayOutputStream out = new ByteArrayOutputStream();
out.append(notesStream.read());
notesStream.close();
notesStream.recycle();
rootMime.recycle();
return out.toString();
}
// Write out a mime entry to a Stream object, includes sub entries
private void printMIME(final MIMEEntity mimeRoot, final Stream out) throws NotesException {
if (mimeRoot == null) {
return;
}
// Encode binary as base64
if (mimeRoot.getEncoding() == MIMEEntity.ENC_IDENTITY_BINARY) {
mimeRoot.decodeContent();
mimeRoot.encodeContent(MIMEEntity.ENC_BASE64);
}
out.writeText(mimeRoot.getBoundaryStart(), Stream.EOL_NONE);
mimeRoot.getEntityAsText(out);
out.writeText(mimeRoot.getBoundaryEnd(), Stream.EOL_NONE);
if (mimeRoot.getContentType().equalsIgnoreCase("multipart")) {
// Print preamble if it isn't empty
final String preamble = mimeRoot.getPreamble();
if (!preamble.isEmpty()) {
out.writeText(preamble, Stream.EOL_NONE);
}
// Print content of each child entity - recursive calls
// Include recycle of mime elements
MIMEEntity mimeChild = mimeRoot.getFirstChildEntity();
while (mimeChild != null) {
this.printMIME(mimeChild, out);
final MIMEEntity mimeNext = mimeChild.getNextSibling();
// Recycle to ensure we don't bleed memory
mimeChild.recyle();
mimeChild = mimeNext;
}
}
}
结果对于每行一个空行。包括使用getEntityAsText
添加的内容。我错过了什么来摆脱多余的线?
out.append(notesStream.read());不需要EOL *参数,这是我的主要问题。 – stwissel
我的意思是:getEntityAsText(out)不接受EOL *参数 - 并且有麻烦 – stwissel
