parsing来自Node js + handlebars的POST请求
我一直在试图parsing来自带有handlebars视图引擎的Node.js POST请求的参数。 不知何故，请求无法parsing参数，我认为这个问题来自于configurationapp.js. 但我无法弄清楚如何解决这个问题。
这是HTML表单
<!DOCTYPE html> <html> <head> </head> <body> <form action="/add/complete" method="POST"> <input type="text" name="name" placeholder="Add your kitten name here" /> <input type="submit" value="Submit" /> </form> </body> </html> 路由器
var express = require('express'); var router = express.Router(); /* GET home page. */ router.get('/', function(req, res) { res.render('index', { title: 'Express' }); }); router.get('/add', function(req, res) { res.render('add', {}); }); router.get('/meow_response', function(req, res) { res.render('meow_response', {}); }); router.post('/add/complete', function(req, res) { // var Kitten = req.Kitten; console.log(req.body); // PROBLEM: it returns empty, while I expect req.body res.redirect('/meow_response'); }); module.exports = router;
和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 hbs = require('hbs'); var app = express(); hbs.localsAsTemplateData(app); app.locals.foo = "bar"; // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'html'); app.engine('html', require('hbs').__express); var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/test'); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.once('open', function (callback) { // yay! }); var routes = require('./routes/routes'); app.use('/', routes); var kittySchema = mongoose.Schema({ name: String }); kittySchema.methods.speak = function() { var greeting = this.name ? "Meow name is" + this.name : "I don't have a name"; console.log(greeting); } var Kitten = mongoose.model('Kitten', kittySchema); // uncomment after placing your favicon in /public //app.use(favicon(__dirname + '/public/favicon.ico')); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public'))); app.use(function(req, res, next) { req.Kitten = Kitten; next(); }); // 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 handlers // development error handler // will print stacktrace if (app.get('env') === 'development') { app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: err }); }); } // production error handler // no stacktraces leaked to user app.use(function(err, req, res, next) { res.status(err.status || 500); res.render('error', { message: err.message, error: {} }); }); module.exports = app;
将路线和/或中间件添加到Express应用程序的顺序非常重要。 所以移动app.use('/', routes); 之后你的bodyParser.*中间件的用法。
