Add more details to package description
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 using
MimeMultipartTransformer is used to process a
Stream of 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.
