问题 I have tried to find a way to enter regular expression into an express routing URL and then access the variable portion of the URL through the request object. Specifically I want to route to the url "/posts/" + any number of digits. Is there a way to do this? Examples: /posts/54 /posts/2 /posts/546 回答1: This should do it: app.get('/posts/:id(\\d+)', function(req, res) { // id portion of the request is available as req.params.id }); EDIT : added regex to path to limit it to digits 回答2: I agree

问题 I would like to remove csrf from my Express 3.0 application as i don't need it there. I use oauth to validate clients. Is the a middleware to whitelist API urls when using express.csrf()? 回答1: You can do that in two ways. 1.) Create a small middleware of your own to allow white list url patterns not to be blocked by csrf like; var express = require("express"); var expressCsrf = express.csrf(); var app = express.createServer(); var customCsrf = function (req, res, next) { // I assume exact

问题 I don't know if this is possible or not. All the research I've done has shown that it is possible with a form and text input. But anyways, Using NodeJs & Express I want to be able to click a button on my webpage, and once it's clicked, it sends a post request to my Node.JS server. Simpler way of saying it: When button is clicked, send info to the server. Goal I'm trying to achieve: When button is clicked, it sends some sort of ID/code/anything to turn on a service from my database. (I have

问题 I've been creating an app with Passport, Express 4 and Jade. I would like to show the user a navbar that changes when they log in.

问题 When you create an Express application you get a routes folder. All routes are registered in the app.js file. However the logic on what happens is located in the files of the routes folder. Is this a synonym for controller folders in other frameworks? Is this the location of where you should add the request/response logic? 回答1: Yes, is kind of the same thing as a controller folder. IMO, you better use different files as you would with controllers in another language because when the

问题 I'm trying to get the response headers from an ajax request but jQuery's getAllResponseHeaders xhr method only displays the "Content-Type" header. Anyone know why?
