问题 How can I properly end a middleware chain in case of error ? In my code I have if (someProblem) { res.status(statuscode).json({message: 'oops'}); return; } Yet the midleware in the chain after that keeps getting called giving me the Can't set headers after they are sent error. 回答1: Middleware does not advance on its own. It only goes to the next step in the chain when you call next() so as long as you don't call next() , then the next step will not execute. So, if you just send a response and

问题 I must have read every question on stack overflow regarding my issue and have not found a solution. I am very new to Ember and Node so please bear with me. The server responds with this format: { "_id" : "53fddf59d72f9b4d3a3e164a" "about" : [ {"from" : "foo"}, {"text" : "bar"}, ... ] } My model looks like this: App.About = DS.Model.extend({ from : DS.attr('string'), text : DS.attr('string'), ... } Adapter & serializer: App.ApplicationAdapter = DS.RESTAdapter.extend({ host: 'http://localhost

问题 I'm having an issue with the domain module. Currently, I'm trying to catch any uncaught errors that are thrown in a request. Using an express middleware and domains. All requests are routed through this function before calling next and moving on to it's proper route. app.use (req, res, next) -> domain = createDomain() domain.on "error", (err) -> res.send(500) domain.dispose() domain.enter() next() The problem is, how do I dispose of the domain if an error is never thrown? I could hoist the

问题 My app was working locally but when I deployed to Heroku, there was an issue. This was my error, It seems that the error was caused by something that I failed to do after I added EJS. 2014-01-06T16:53:39.285571+00:00 app[web.1]: module.js:340 2014-01-06T16:53:39.285956+00:00 app[web.1]: throw err; 2014-01-06T16:53:39.286233+00:00 app[web.1]: ^ 2014-01-06T16:53:39.288439+00:00 app[web.1]: Error: Cannot find module 'ejs' 2014-01-06T16:53:39.288439+00:00 app[web.1]: at Function.Module.

问题 In my express app I've set static files to be served from the /public directory with this line: app.use(express.static(__dirname + '/public')); Now I need to add a middleware for authentication before serving the static content and if the user is not authenticated to be redirected to a route for authentication (e.g., /login ). I'm not really sure how I have to do it. Any ideas? 回答1: Since you didn't specify it, I'm going to assume that you already have some kind of authentication system. In

问题 I set up the following Express 4 middleware stack: const app = express(); const router = express.Router(); router.get('/test', testResponse); app.use(checkAccessToken); app.use(router); app.use(sendResponse); //Error Handling app.use(function(err,req,res,next) { // ...
