load method

@override Future load(HttpConnect connect, String uri, { bool useCache = true, })

Loads the asset of the given URI to the given response.

• useCache - whether to use the cache. If true (default), it will check the cache first, and update the cache if ncessary.

Implementation

@override
Future load(HttpConnect connect, String uri, {bool useCache = true}) async {
  assert(uri.startsWith('/'));
  assert(uri == Path.normalize(uri)); //caller's job to avoid HTTP directory traversal

  var path = uri.substring(1); //uri must start with '/', but path can't
  path = Path.join(rootDir, path);

  if (rootDir != path && !Path.isWithin(rootDir, path)) {
    //Note: this won't happen if caller's does invoke [Path.normalize]
    connect.server.logger.severe('$path not in $rootDir', null,
        StackTrace.current); //for debugging
    throw Http404(uri: Uri.tryParse(uri));
  }

  final file = File(path);
  if (await file.exists())
    return loadAsset(connect, FileAsset(file), useCache ? cache: null);

  if (await Directory(path).exists())
    return _loadFileAt(connect, uri, path, connect.server.indexNames, 0,
        useCache ? cache: null);

  throw Http404(uri: Uri.tryParse(uri));
