问题 How can I add middleware to the shelf pipeline that adds default HTTP headers to each request? 回答1: Update There is now a pub package to simplify adding CORS headers see https://pub.dartlang.org/packages/shelf_cors Original See also https://groups.google.com/a/dartlang.org/forum/#!topic/cloud/2Vn_IqzGtTc final Map<String, String> _headers = {'Access-Control-Allow-Origin': '*', 'Content-Type': 'text/html'}; // for OPTIONS (preflight) requests just add headers and an empty response shelf

问题 I've been trying to write a simple server that accepts username/password credentials, validates them, then creates a JWT token for the client that they then use to gain access to certain routes. I am able to do everything up to the point of receiving and validating the client's JWT on the server side. void main() { //use Jwt based sessions and create the secret using a UUID JwtSessionHandler sessionHandler = new JwtSessionHandler('ffl_sales_server', new Uuid().v4(), auth.lookupByUsername); /

Authenticate websocket connection in Dart using shelf_auth and shelf_web_socket

由 不问归期 提交于 2019-12-11 08:27:19
问题 Using shelf_auth I can extract current user information from request this way: getAuthenticatedContext(request) .map((ac) => ac.principal.name) .getOrElse(() => 'guest') but, obviously, I need a request for that to work :) On the other hand, using shelf_web_socket, establishing of websocket connection executes handler like that: handleWS(CompatibleWebSocket ws){ // Here I should get user from getAuthenticatedContext() // but I cannot due to absence of Request here. ws.messages.listen(...); };

问题 Using shelf_static to serve static web pages through Dart is no problem: var staticHandler = createStaticHandler(staticPath, defaultDocument:'home.html'); io.serve(staticHandler, 'localhost', port).then((server) { print('Serving at http://${server.address.host}:${server.port}'); }); and I can use shelf_route fine for dynamic web pages: Router routes = new Router() ..get('/item/{itemid}', handler.doItem); var handler = const shelf.Pipeline() .addHandler(routes.handler); io.serve(handler,
