在表單上提交POST請求時，請保持未定義的身體

Question

正如標題所說，我一直在這裏工作了大約3個小時，試圖弄清楚爲什麼POST主體總是未定義 - 無論我做什麼。任何人都可以看看我的JADE/JS，並幫我弄清楚我的問題？

JADE

doctype html

server.js

//Add necessary dependencies (Express and MongoJS) 
var express = require('express'); 
var app = express(); 
var mongojs = require('mongojs'); 
var db = mongojs('advisingApp',['advisingApp']); //sets the database for the project 
//Test to make sure server is properly configured 
/*app.get('/', function (request, response) { 
    response.send("Hello world from server.js!"); 
});*/ 

//Tell web app where to look for "static" files in directory - (it's looking in the default parent directory) 
app.use(express.static(__dirname)); 

// app.get("/", function (request, response) { 
// console.log("GET Request Received") 
// db.advisingApp.find(function (err, docs) { 
//  console.log(docs); 
//  response.json(docs);

// }); 
app.post("/", function (req, res) { 
    console.log("POST Request Received"); 
    console.log(req.body); 
}); 
app.listen(3000); 
console.log("Server running smoothly on port 3000");

試試這個

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 routes = require('./routes/index'); 
//var mongoose=require('mongoose'); 
//mongoose.connect('mongodb://localhost/test'); 

var app = express(); 

// view engine setup 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'jade'); 

// 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(express.static(path.join(__dirname, 'public'))); 


app.get("/",function(req,res){ 
    res.render('view'); //i named ur given jade as view.jade 
}) 
app.post("/", function (req, res) { 
    console.log("POST Request Received"); 
    console.log(req.body); 
}); 
// app.use('/', routes); 
// app.use('/users', users); 

// 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: {} 
    }); 
}); 
// 
app.listen('3000',console.log('listening')); 
// module.exports = app;
