This question already has an answer here: “Cannot GET /” with Connect on Node.js 10 answers I'm trying to launch my node server using an example from an AngularJS book (server.js). var connect = require('connect'); connect.createServer( connect.static("../angularjs") ).listen(5000); Initially I was getting "object has no method static" so I re-installed the connect include and now when I do: node server.js I get a blinking cursor in CMD (Windows) and "Cannot GET /" from my browser. Any ideas folks? Thanks! Your application is working just fine. You just need to specify the name of the file you

Socket.connect() to 0.0.0.0: Windows vs. Mac

阅读更多关于 Socket.connect() to 0.0.0.0: Windows vs. Mac

问题 Imagine the following code: String hostName = "0.0.0.0"; int port = 10002; int timeout = 5000; Socket socket = new Socket(); socket.connect(new InetSocketAddress(hostName, port), timeout); On the Mac it works fine and executes the connect (even with nothing running on port 10002) and on Windows I get the following exception: java.net.SocketException: Permission denied: connect What's the difference here and what would be the alternative on Windows? This is used in unit tests. Regards Jonas

C# How do I stop a tcpClient.Connect() process when i'm ready for the program to end? It just sits there for like 10 seconds!

阅读更多关于 C# How do I stop a tcpClient.Connect() process when i'm ready for the program to end? It just sits there for like 10 seconds!

问题 This is one of my first issues. Whenever I exit out the program, tcpClient.Connect() takes forever to close. I've tried a ton of things, and none of them seem to work. Take a look at the CreateConnection() thread, if the client isn't connected yet... and I close the program, it takes forever to close. If it IS connected, it closes immediately. I know this can be done with some kind of timeout trick, but i've tried a few and none of them worked. Please provide a code example if you can. Also,

Handling text/plain in Express (via connect)?

阅读更多关于 Handling text/plain in Express (via connect)?

问题 I am using Express 3, and would like to handle text/plain POSTs. Express 3 uses connect's bodyParser now (I think the old Express code got moved to connect). The documentation for bodyParser gives some details about how to make it support additional file types. And I found an excellent blog post about how handling text/plain was done in old versions of Express). Should I explicitly require connect (and let node's require cache the modified version)? Or is connect exposed via express somewhere

Node.js / Express.js - How to override/intercept res.render function?

阅读更多关于 Node.js / Express.js - How to override/intercept res.render function?

I'm building a Node.js app with Connect/Express.js and I want to intercept the res.render(view, option) function to run some code before forwarding it on to the original render function. app.get('/someUrl', function(req, res) { res.render = function(view, options, callback) { view = 'testViews/' + view; res.prototype.render(view, options, callback); }; res.render('index', { title: 'Hello world' }); }); It looks like a contrived example, but it does fit in an overall framework I'm building. My knowledge of OOP and Prototypal inheritance on JavaScript is a bit weak. How would I do something like
