无法在视图目录中查找“/ user / profile”

我正在尝试使用node.js，express.js和mongodb构build一个购物车。 我正在build立注册function。 我的问题是当我尝试访问本地主机：3000 /用户/configuration文件链接我得到这个错误信息：

Failed to lookup view "/user/profile" in views directory "/Users/vynguyen/shopping-cart/views Error: Failed to lookup view "/user/profile" in views directory "/Users/vynguyen/shopping-cart/views" at EventEmitter.render (/Users/vynguyen/shopping-cart/node_modules/express/lib/application.js:579:17) at ServerResponse.render (/Users/vynguyen/shopping-cart/node_modules/express/lib/response.js:960:7) at /Users/vynguyen/shopping-cart/routes/index.js:34:6 at Layer.handle [as handle_request] (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/layer.js:95:5) at next (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/route.js:131:13) at Route.dispatch (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/route.js:112:3) at Layer.handle [as handle_request] (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/layer.js:95:5) at /Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:277:22 at Function.process_params (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:330:12) at next (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:271:10) at csrf (/Users/vynguyen/shopping-cart/node_modules/csurf/index.js:117:5) at Layer.handle [as handle_request] (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/layer.js:95:5) at trim_prefix (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:312:13) at /Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:280:7 at Function.process_params (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:330:12) at next (/Users/vynguyen/shopping-cart/node_modules/express/lib/router/index.js:271:10

profile.hbs文件位于正确的文件夹，但由于某种原因，服务器将不会拉起来。

这是整个文件结构： 在这里input图像描述

这是我的index.js文件：

 var express = require('express'); var router = express.Router(); var csrf = require('csurf'); var passport = require('passport'); var Product = require('../models/product'); var csrfProtection = csrf(); router.use(csrfProtection); /* GET home page. */ router.get('/', function(req, res, next) { Product.find(function(err, docs) { var productChunks = []; var chunkSize = 3; for (var i = 0; i < docs.length; i += chunkSize) { productChunks.push(docs.slice(i, i + chunkSize)); } res.render('shop/index', { title: 'Shopping Cart', products: productChunks }); }); }); router.get('/user/signup', function(req, res, next) { res.render('user/signup', {csrfToken: req.csrfToken()}); }); router.post('/user/signup', passport.authenticate('local.signup', { successRedirect: '/user/profile', failureRedirect: '/user/signup', failureFlash: true })); router.get('/user/profile', function(req, res, next){ res.render('/user/profile'); }); module.exports = router; 

这是我的app.js：

 var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var expressHbs = require('express-handlebars'); var mongoose = require('mongoose'); var session = require('express-session'); var passport = require('passport'); var flash = require('connect-flash'); var routes = require('./routes/index'); var userRoutes = require('./routes/user'); var app = express(); mongoose.connect('localhost:27017/shopping'); require('./config/passport'); // view engine setup app.set('views', __dirname+'/views'); app.engine('.hbs', expressHbs({defaultLayout: 'layout', extname: '.hbs'})); app.set('view engine', '.hbs'); // uncomment after placing your favicon in /public //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(session({secret: 'mysupersecret', resave: false, saveUninitialized: false})); app.use(express.static(path.join(__dirname, 'public'))); app.use(flash()); app.use(passport.initialize()); app.use(passport.session()); app.use('/user', userRoutes); app.use('/', routes); // catch 404 and forward to error handler app.use(function(req, res, next) { var err = new Error('Not Found'); err.status = 404; next(err); }); // error handler app.use(function(err, req, res, next) { // set locals, only providing error in development res.locals.message = err.message; res.locals.error = req.app.get('env') === 'development' ? err : {}; // render the error page res.status(err.status || 500); res.render('error'); }); module.exports = app;

当parsing视图文件path时，带有前导斜杠的视图path将parsing为根目录，从而导致错误。 您需要parsing相对于您的views目录的视图文件。 在res.render方法中使用user/profile或./user/profile将正确地parsing视图文件。

正确的代码： res.render('user/profile')或res.render('./user/profile')
