使用邮递员将数据插入数据库时，控制器文件中显示错误

Question

在使用节点时。js我无法将数据插入数据库，我使用的是express。js，mongoose，但我在代码中提到的作为注释的获取错误

Blockquote错误为Blockquote TypeError:无法读取层的插入（E:\node\website\controller\signup.js:5:25）处未定义的属性“名称”。在路由的下一个（E:\node\website\node\u modules\express\lib\router\layer.js:95:5）处理[作为句柄\u请求]（E:\node\website\node\u modules\express\lib\router\route.js:137:13）。层上的调度（E:\node\website\node\u modules\express\lib\router\route.js:112:3）。在E:\node\website\node\u modules\express\lib\router\layer.js:95:5处处理[作为句柄\u请求]（E:\node\website\node\u modules\express\lib\router\index）。js:281:22 at功能。在函数的下一个（E:\node\website\node\u modules\express\lib\router\index.js:335:12）处（E:\node\website\node\u modules\express\lib\router\index.js:275:10）处理_参数。在层的路由器（E:\node\website\node\u modules\express\lib\router\index.js:174:3）上处理（E:\node\website\node\u modules\express\lib\router\index.js:47:12）。在E:\node\website\node\modules\express\lib\router\layer.js:95:5）的trim\u前缀（E:\node\website\node\modules\express\lib\router\index.js:317:13）处处理[作为handle\u请求]（E:\node\website\node\ru modules\express\lib\router\index.js）。js:284:7 at函数。在第层的expressInit（E:\node\website\node\modules\express\lib\router\index.js:335:12）的下一个（E:\node\website\node\modules\express\lib\router\index.js:275:10）处理参数（E:\node\website\node\modules\express\lib\middleware\init.js:40:5）。在E:\node\website\node\modules\express\lib\router\layer.js:95:5）的trim\u前缀（E:\node\website\node\modules\express\lib\router\index.js:317:13）处处理[作为handle\u请求]（E:\node\website\node\ru modules\express\lib\router\index.js）。js:284:7 at函数。在查询（E:\node\website\node\modules\express\lib\router\index.js:335:12）的下一个（E:\node\website\node\modules\express\lib\router\index.js:275:10）中，在查询（E:\node\website\node\modules\express\lib\middleware\query.js:45:5）的Blockquote//控制器文件中处理参数，命名为注册。js

var express=require('express');
var post1=require('../model/singup')
var router=express.Router();
var insert=(req,res)=>{
    var name1= req.body.name;// error:name is not defined
    var email1= req.body.email;//error:email is not defined
    var password1= req.body.password;//error:password is not defined
    post1.create({
        name: name1,email:email1,password:password1
    },(err,result)=>{
        if(err){res.json({message:'error'
           })
        }
        else{res.json({message:'sucessful',result:result   
        })
     } 
})
}
router.post('/signup',insert);
router.get('/h',(req,res)=>{
    res.json({ 
        message:'insert'
    })
    console.log("insert");
    })
module.exports=router;

Blockquote//名为signup的模型文件。js

require('../db');
var mongoose=require('mongoose');
mongoose.Promise=require('bluebird');
var schema= new mongoose.Schema({
    name:{type:String,required:true},
    email:{type:String,required:true},
    password:{type:String,required:true},   
},
{timestamp:true});
module.exports=mongoose.model('post1',schema);

用于数据库连接//db.js文件

var mongose=require('mongoose');
mongose.set('useNewUrlParser', 'true');
mongose.set('useCreateIndex', 'true');
mongose.set('useFindAndModify', 'true');
mongose.connect("mongodb://127.0.0.1:27017/website");
var db=mongose.connection;
db.on('error',console.error.bind(console,'connection error'));
db.once('open',(req,res)=>{
    console.log("connected with db!!!");
})

区块报价//index.js

var app=require('./server')
var signup=require('./controller/signup')

 var session=require('express-session')
app.set('viewengin','ejs')
app.set('useNewUrlParser', 'true')
app.set('useUnifiedTopology', 'true')
app.use('/user',signup)
app.use(session({
    secret:'keyboard cat ',
    resave:false,
    cookies:{
        secrue:true
    },
}))
app.all('*',(req,res)=>{
    return res.json({status: 205,message: 'not found'});
})
var server=app.get('/',(req,res)=>{
req.end()
});

似乎你错过了身体解析器中间件。

$ npm i body-parser

var express=require('express');
var bodyParser = require('body-parser');

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))

// parse application/json
app.use(bodyParser.json())
