Lab 8.1 - Validation.js issue - returning false negative
Hi @davidmarkclements , Hi all,
I am encountering validation issue when running node validate.js
It returns
PS D :\LinuxFoundation\LFW212\Lab8.1> node .\validate.js
☑️ GET http://localhost:3011/bad-route responded with 404 response
☑️ GET http://localhost:3011/ responded with 400
☑️ GET http://localhost:3011/?url=http://localhost:7686/bad-route responded with 404 response
⛔️ GET http://localhost:3011/?url=http://localhost:7686/redir must forward 301 response from upstream server, got 404
It says, my app doesn't forward 301.
To test this, I created a server that will return me 301 response, running on http://localhost:6000/redir
Then I hit my app with query ?url=http://localhost:6000/redir
It looks fine on Postman
I did the same using chrome browser, and it returns me the same result as Postman (301 response)
I wonder, is there any issue with the validation.js
file for Lab 8.1? I am using the newest 2023 version.
My codes looks like this (using Express)
var express = require("express"); var router = express.Router(); var createError = require("http-errors"); const { createProxyMiddleware } = require("http-proxy-middleware"); function setProxyTarget(req, res, next) { const url = req.query.url; if (url) { try { new URL(url); res.locals.url = url; next(); } catch (err) { res.status(400); } } else { return next(createError(400)); } } function proxy(req, res, next) { const settingProxy = createProxyMiddleware({ target: res.locals.url, changeOrigin: true, logger: console, followRedirects: true, }); settingProxy(req, res, next); } router.get("/", setProxyTarget, proxy); module.exports = router;

@jimmycheung22 all the code does is hit the end point and check status code response. What might be happening is connection to a server running old code? Are you manually setting the port? 3011 looks human-set to me - if you are then you're probably just hitting the wrong server or something. Testing against another port endpoint doesn't help confirm/deny any issues - you need to check against the same exact server instance
