Dart standard library (dart:io) Dart

Isang Dart snippet para sa Dart standard library (dart:io) na sumasagot sa mga request sa /pixel.gif gamit ang empty GIF, na isang beses lang dine-decode sa startup.

Dart standard library (dart:io) Dart

Path

File: server.dart
Patakbuhin: dart run server.dart

import 'dart:convert';
import 'dart:io';

final gif = base64Decode('R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==');

Future<void> main() async {
  final server = await HttpServer.bind(InternetAddress.anyIPv4, 8080);
  await for (final request in server) {
    final response = request.response;
    if (request.method == 'GET' && request.uri.path == '/pixel.gif') {
      response.headers
        ..contentType = ContentType('image', 'gif')
        ..set(HttpHeaders.cacheControlHeader, 'no-store');
      response.contentLength = gif.length;
      response.add(gif);
    } else {
      response.statusCode = HttpStatus.notFound;
    }
    await response.close();
  }
}

Pinatakbo namin ang snippet na ito at ikinumpara ang mga byte na ibinalik nito.
