问题 Sails 0.10.0-rc7 Sails Socket IO : Client not receiving response from server. Using sails built in blueprints I am attempting to get information from my server using this functionality. (Im looking to use the default behaviour) Client //Client on different server (localhost:8000) //Sails server var socket = io.connect('http://localhost:1337'); socket.get('/event',function serverSays(err,events){ if (err) console.log(err) console.log(JSON.stringify(events)); }); Server Event Model module

问题 I need the help/support/guidance regarding the Socket.io On My server page i.e app.js, I initialized the Socket and it works fine. Now I want to call the emit function to some other page. But I did not get the event from another page because the event generated under connection. I will share the pseudo code by which you can get some idea about app.js page const io = require('socket.io'); const server = io.listen(3003); const triggerEvent = (socket) => { return socket.emit('event-trigger',

问题 As a part of an ongoing effort, I'm changing my current callbacks technique to promises using blue-bird promise library. I would like to implement this technique with Socket.IO as well. How can I use Socket.IO with promises instead of callbacks? Is there any standard way of doing it with Socket.IO? any official solution? 回答1: You might look into Q-Connection, which facilitates RPC using promises as proxies for remote objects and can use Socket.IO as a message transport. 回答2: Bluebird (and

问题 Is it possible to do something like that with socket io : socket.on('event.here', async (data) => { const result:any = await webservice(); } I'm not quite sure how to do it ? 回答1: Yes you can do it, but it depends on what you want to do. If you want to be able to await for some async operation inside callback than you are all set. But if you want for the next event to not fire before handling of previous one was finished than it won't work that way. Here is a little simulation: let socket = {

问题 I need to dynamically load/render part of a page in nodejs (v1.8.15) with express (>3.0) framework. Generally, I want to create a single-page app. I have a menu at the top of the page with links.
