class Net_API MultipartWriter
This class is used to write MIME multipart
messages to an output stream.
The format of multipart messages is described
in section 5.1 of RFC 2046.
To create a multipart message, first create
a MultipartWriter object.
Then, for each part, call nextPart() and
write the content to the output stream.
Repeat for all parts.
After the last part has been written,
call close() to finish the multipart message.
{
public:
explicit MultipartWriter(std::ostream& ostr);
Creates the MultipartWriter, using the
given output stream.
Creates a random boundary string.
MultipartWriter(std::ostream& ostr, const std::string& boundary);
Creates the MultipartWriter, using the
given output stream and boundary string.
~MultipartWriter();
Destroys the MultipartWriter.
void nextPart(const MessageHeader& header);
Opens a new message part and writes
the message boundary string, followed
by the message header to the stream.
void close();
Closes the multipart message and writes
the terminating boundary string.
Does not close the underlying stream.
std::ostream& stream();
Returns the writer's stream.
const std::string& boundary() const;
Returns the multipart boundary used by this writer.
static std::string createBoundary();
Creates a random boundary string.
The string always has the form
MIME_boundary_XXXXXXXXXXXX, where
XXXXXXXXXXXX is a random hexadecimal
number.
