Package for working with MIME type definitions and for processing streams of MIME multipart media types.
MimeTypeResolver class can be used to determine the MIME type of
a file. It supports both using the extension of the file name and
looking at magic bytes from the beginning of the file.
There is a builtin instance of
MimeTypeResolver accessible through
the top level function
lookupMimeType. This builtin instance has
the most common file name extensions and magic bytes registered.
print(lookupMimeType('test.html')); // Will print text/html print(lookupMimeType('test', [0xFF, 0xD8])); // Will print image/jpeg print(lookupMimeType('test.html', [0xFF, 0xD8])); // Will print image/jpeg
You can build you own resolver by creating an instance of
MimeTypeResolver and adding file name extensions and magic bytes
MimeMultipartTransformer is used to process a
bytes encoded using a MIME multipart media types encoding. The
transformer provides a new
MimeMultipart objects each of
which have the headers and the content of each part. The content of a
part is provided as a stream of bytes.
Below is an example showing how to process an HTTP request and print the length of the content of each part.
// HTTP request with content type multipart/form-data. HttpRequest request = ...; // Determine the boundary form the content type header String boundary = request.headers.contentType.parameters['boundary']; // Process the body just calculating the length of each part. request .transform(new MimeMultipartTransformer(boundary)) .map((part) => part.fold(0, (p, d) => p + d)) .listen((length) => print('Part with length $length'));
Take a look at the
HttpBodyHandler in the http_server
package for handling different content types in an HTTP request.
