Question

我的问题是当我尝试渲染页面时，req.body变得未定义。

我的应用代码：

var https = require('https');
var fs = require('fs');
var mongourl = "mongodb://localhost:27017/auntyinda";
var mongoose = require('mongoose');
fs.readdirSync(__dirname + '/models').forEach(function (filename) { 
  if (~filename.indexOf('.js')) require(__dirname + "/models/" + filename);
});
//var queries = require('./mongoq/query')

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 expressSession = require('express-session');
var passport = require('passport');

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

var app = express();
var server = https.createServer({
  cert: fs.readFileSync(__dirname + '/my.crt'),
  key: fs.readFileSync(__dirname + '/my.key')
},app).listen(4000);

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

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
//app.configure(function(){

app.use(logger('dev'));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
//app.use(require('connect').bodyParser())
app.use(cookieParser());
app.use(expressSession( {
  secret: process.env.SESSION_SECRET || 'sonic12',
  resave: false,
  saveUninitialized: false
  }))
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(path.join(__dirname, 'public')));

//});

mongoose.connect(mongourl)
//app.use('/', myPass);
app.use('/', routes);
//app.use('/users', users);


//app.locals.appdata = require("./data.json")

我的路线代码：

router.post('/register', function(req, res, next) {
  regcheck(req.body.username, req.body.password, req.body.passwordConfirm, function (error) {
    if (error) {
      console.log(req.body) //OUTPUT IS WHAT IS EXPECTED. NICE JSON FORMAT.
      res.render('register', {
        title: 'Register',
        classname: 'register',
        socialIcons: socialIcons,
        isAuthenticated: false,
        regdata: req.body,
        err: error
      })
    }
  })
})

我希望渲染器使用regdata对象来重新填充返回注册表单的数据。但是由于一些奇怪的原因，它到达渲染时变得不确定。

我的EJS文件在顶部包含此行：

<% console.log('Error recieved: '); console.log(err); console.log(regdata); %>

但console.log(regdata)的输出为undefined。这里发生了什么？ err打印应该。在此先感谢您的帮助。

试试这个， <pre><%= regdata %></pre>

我认为你错过了某个=。咨询docs。

req.body在传递给res.render之后变得不确定
