Expressjs Body-Parser：如何解决“ TypeError：无法读取未定义的属性'名称'”-已经检查了所有先前的答复者

Question

在我想从表单获取数据之前，代码可以正常工作，我expressjs已经使用并且已经知道body-parser，但是当我使用router.post('/register',function())此错误时：

我得到的错误

TypeError：无法在Layer.handle处e：\ 2016 \ passport \ controllers \ users.js：20：23读取未定义的属性“名称”（作为handle_request）（e：\ 2016 \ passport \ node_modules \ express \ lib \ router \ layer.js：95：5）在Route.dispatch（e：\ 2016 \ passport \ node_modules \ express）下（e：\ 2016 \ passport \ node_modules \ express \ lib \ router \ route.js：131：13） \ lib \ router \ route.js：112：3）在Layer.handle [作为handle_request]

我app.js已经使用body-parser

var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var exphbs = require('express-handlebars');
var expressValidator = require('express-validator');
var flash = require('connect-flash');
var session = require('express-session');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var mongo = require('mongodb');
var mongoose = require('mongoose');
var http=require('http');
mongoose.connect('mongodb://localhost/loginapp');
var db = mongoose.connection;
var app=express();

// set up routers
app.use(require('./controllers'));


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


// set up public files
app.use( express.static('public'));



// set up BodyParser Middleware
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());

// Express Port
 http.createServer(app).listen(process.env.Port || 2000,function(){
 console.log('login app Run!');
  });

路由器文件users.js发布此路由时收到错误消息

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

    var name= req.body.name;
    var username= req.body.username;
    var email= req.body.email;
    var password= req.body.password;
    var password2= req.body.password2;
    resp.render('register');

    });

我的ejs档案

<pre>
<form method="post" action="/users/register">
  <input type="text"  name="name">          
  <input type="text"  name="username">
  <input type="email" name="email">
 <button type="submit" >Submit</button>
   </form>

</pre>

您需要在人体分析器之前输入“ ./controllers”！应该在任何控制器之前调用body-parser，以便解析请求主体并将其附加到req。
