问题 Right now, I'm trying to make an API, and one of its functions is to take a file and upload it to another website, sort of like uploading a file through the API as some sort of "proxy". The website I'm sending the file to requires additional steps to work (namely sending the destination in another request) and I wanted to have my API do that all in one request instead, where that request already had all the details needed. I've gotten the request for the destination done, but I'm having a

问题 I have created some standard middleware with some logic, and depending on the logic I need to call some 3rd party middleware. Middleware is added using app.use(), which is where I add my custom middleware. Once in my middleware I no longer have access to app.use(), how do I call the middleware? Here is some code: Any ideas ? const customerData = (req, res, next) => { try { console.log('Started'); if (process.env.STORE_CUSTOMER_DATA === 'true') { // Here is some custom middleware that doesn't

问题 I am building a webapp in the form of a network of sorts with basic CRUD actions. I am in the process of splitting up my router files as they are becoming rather large. I have an 'actions' route which does things such as selecting an in individual post to view, voting on a post, viewing a profile and commending a user. I cannot seem to find a way to allow me to split these 'action' routes into a seperate file and then use them as needed in the main route. //index.js file in routes folder var

Here is my config.js: var flash = require('connect-flash'); app = module.exports = express(); app.use(kraken(options)); //flash app.use(flash()); app.use(function (req, res, next) { res.locals.messages = require('express-messages')(req, res); next(); }); My controller : router.post('/somePath', function (req, res) {

问题 I have a few node processes that I'm trying to reverse proxy into one localhost port. Node-http-proxy seemed like the simplest solution. I'm proxying to a couple of node.js process running express (port 3100 & 3000 in the example below), and a process running node.js with restify (2700). var http = require('http'), httpProxy = require('http-proxy'); var proxy = httpProxy.createProxyServer({}); var server = require('http').createServer(function(req, res) { if (req.url.match(/^(\/api\/search|\

问题 I'm have a SQL Server database with images of type varbinary . I need to convert the varbinary and return the image to a web page. Help would be appreciated.

Node.js How to convert to image from varbinary of MS Sql server datatype Something like ... var image = new Buffer(rs.recordset[0].Image).toString('base64'); res.type('image/jpeg; charset=utf-8'); res.status(200).end(image); <ng-template ngbSlide *ngFor="let image of images"

问题 I'm trying to write an Express route that takes an image URI in the POST body and then saves the image into a Google Cloud Storage Bucket. I'm not able to persist this image to local disk and need to stream the buffer straight to the GCS bucket. My route creates a 4KB "stub" in the GCS bucket but there's no image payload. My nodejs then proceeds to crash... Q: What is the correct way to .pipe() the results of the https.request() to blob.createWriteStream()? Is this the right approach? I've

问题 So I want to be able to do something like this: "{{tickets." + index + ".comments.0.account}}" I want to be able to specify the index of the array that I am trying to get data from with a javascript variable. Currently this code gives me an error which says: Expecting 'ID', got 'STRING' I am actually using express-handlebars with Node.js if this makes a difference. 回答1: Create a helper: Handlebars.registerHelper('getTicketAccount', function(context, i) { // Error handling ommitted for brevity
