express

问题 I am on express3.x and using formidable app.post "/up",(req,res)-> formidable = require('formidable') form = new formidable.IncomingForm() form.uploadDir = __dirname + "/uploads" form.encoding = 'binary' form.addListener 'file',(name,file) -> #write file console.log('file uploaded') return console.log('$$$$$$$$$$$') form.addListener 'end', -> console.log('end') res.end() return console.log('@@@@@$$$$') form.parse req,(err,fields,files)-> console.log('parse') console.log(err) if(err) return

问题 So in Express you can do: app.get('/logo/:version/:name', function (req, res, next) { // Do something } and app.all('/logo/:version/:name', function (req, res) { // Do something } Is there a way to just have two methods (ie. GET and HEAD)? Such as: app.get.head('/logo/:version/:name', function (req, res, next) { // Do something } 回答1: Just pull out the anonymous function and give it a name: function myRouteHandler(req, res, next) { // Do something } app.get('/logo/:version/:name',

问题 I've looked everywhere I can to find a solution to this. The only thing I've found is an unanswered post. I apologize if I've overlooked something. The problem is that when I try to get the POST values in the /createQuestion API, the body is empty/undefined. I get errors like this Cannot read proprety 'question' of undefined coming from the API. The Express API: app.post("/createQuestion", function(req, res) { var questionType = req.body.question.type; var questionText = req.body.question

问题 As far as I can tell I'm configuring my global middleware function as described in the docs and in every forum post on the subject, but it is not being called. Does anyone see what I'm doing wrong? express 3.2.5. In the log output I see the following: Express server listening on port 9000 inside route GET / 200 7ms - 2b I expect to see "inside middleware", then "inside route". Instead, I just see "inside route". The code: var express = require('express'), http=require('http'), path=require(

问题 I must have missed something, but according to all the tutorials I've found, this is how you do basic auth with a node application using express and passport + passport-local . I know it's not according to best practice, I'm just trying to get a POC going: 'use strict' var express = require('express'); var passport = require('passport'); var LocalStrategy = require('passport-local').Strategy var app = express(); var users = { 'user': 'secretpass'}; passport.use(new LocalStrategy( function

问题 I'm using node and express for the back end of an iOS application. Data is stored in a SQL Server database, so iOS apps query the server, the server queries the database, server receives the db response, and then forwards the response to the iOS application. I'm trying to figure out how caching works though. I'm serving a lot of static content - blog articles for example. So I planned to use etags, but I'm not sure how it's supposed to work. I make a request, get content, and cache the

问题 I have found many different node.js authentication modules. Ei passport-kerberos. But I am looking to make background https calls to another kerberos authenticated site w/ an authorization token.
