javascript - How to split the dev-server.js file in vue to several separated files? -
i using vue.js compose app, , mocked login api of localhost in dev-server.js, want separate code login api independent file, should do? besides there code cors, here code:
var app = express() var bodyparser = require('body-parser') var multer = require('multer') var upload = multer() app.use(bodyparser.json()) app.use(bodyparser.urlencoded({extended: true})) // cors var allowcrossdomain = function (req, res, next) { res.header('access-control-allow-origin', 'http://localhost:8080') res.header('access-control-allow-methods', 'get, post, put, delete') res.header('access-control-allow-headers', 'content-type, x-token') res.header('access-control-allow-credentials', 'true') next() } app.use(allowcrossdomain) // mock localhost api var apiroutes = express.router() // login api; const useraccountlist = ['100000', '100001', '100002', '100003'] apiroutes.post('/user/login', upload.array(), function (req, res) { if (useraccountlist.indexof(req.body.account) < 0){ return res.json({ code: 50000, msg: 'the account or password not correct, please try again' }); } } app.use('/api', apiroutes);
(i think it's question node , express, instead of vue.js)
while express built web app middleware, think it's time split logic different middleware.
so can put login logic independent .js file middleware like:
// login.js const useraccountlist = ['100000', '100001', '100002', '100003'] const loginmiddleware = function (req, res, next) { if (useraccountlist.indexof(req.body.account) < 0){ res.json({ code: 50000, msg: 'the account or password not correct, please try again' }); } }; module.exports = loginmiddleware; then requiring app like:
// app.js const loginmiddleware = require('./login'); // ... apiroutes.post('/user/login', loginmiddleware); here official express document how write middleware properly: https://expressjs.com/en/guide/using-middleware.html
