Question

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 expressValidator = require('express-validator');

var routes = require('./routes/index');
var users = require('./routes/users');
var auth = require('./routes/auth');

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 }));

//validator
app.use(expressValidator({
  errorFormatter: function(param, msg, value) {
    var namespace = param.split('.')
        , root    = namespace.shift()
        , formParam = root;

    while(namespace.length) {
      formParam += '[' + namespace.shift() + ']';
    }
    return {
      param : formParam,
      msg   : msg,
      value : value
    };
  }
}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/users', users);
app.use('/auth', auth);

// 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;

此部分是app.js

var express = require('express');
var router = express.Router();

router.post('/register', function(req,res,next) {

    // Get Form Values

    var email = req.body.email;
    var username = req.body.username;
    var password = req.body.password;
    var password2 = req.body.password2;

    // Form Validation
    req.checkBody('email','Email field is required').notEmpty();
    req.checkBody('email','Email not valid').isEmail();
    req.checkBody('username','Username field is required').notEmpty();
    req.checkBody('password','Password field is required').notEmpty();
    req.checkBody('password2','Passwords do not match').equals(req.body.password);


    var errors = req.validationErrors();

    if(errors){
        console.log(req.body);
        console.log(req.param);
        console.log(errors);
    } else{
        res.send('email : ' + email +'username : ' + username + ' password : ' + password);

    }
});



module.exports = router;

此部分是auth.js

这部分是客户端部分

我正在单独开发客户端部件和服务器部件

我不知道为什么身体解析器不起作用

请求正文始终未定义。

快递版：4.13.3 body-parser版本：1.14.1

body-parser不起作用，req.body未定义
