Dart

Create MIME Containing HTML

Calls SetBodyFromHtml to load HTML into the MIME body. Also sets the Content-Type header to "text/html", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the HTML.

  // See Global Unlock Sample for sample code.

  final mime = CkMime();

  // Add a few header fields:
  mime.addHeaderField('Description', 'this is a test');
  mime.addHeaderField('MyId', '123');

  final htmlDoc = '<html><body>Test</body></html>';

  // Set the MIME body via SetBodyFromHtml.  This also
  // has the intended side-effect of adding the Content-Type
  // and Content-Transfer-Encoding headers.
  mime.setBodyFromHtml(htmlDoc);

  print(mime.getMime());

  // The MIME should look like this:

  // Description: this is a test
  // MyId: 123
  // Content-Type: text/html; 
  // Content-Transfer-Encoding: 7bit
  // 
  // <html><body>Test</body></html>

  // Note: The Content-Transfer-Encoding may be changed.
  // For example, to use "base64", do this:
  mime.encoding = 'base64';

  // Show the MIME again, this time using the base64 
  // transfer encoding:
  print(mime.getMime());

  // It should look like this:

  // Description: this is a test
  // MyId: 123
  // Content-Type: text/html; 
  // Content-Transfer-Encoding: base64
  //
