NodeJS API Mongodb不保存数据

Question

最近我开始创建一个nodejs和mongo API，尝试保存数据但是无法保存任何信息。唯一可以获得的信息是生成POST请求时生成的ID。我使用POSTMANT来测试de API，但没有成功保存数据。唯一的信息可以得到的只是ID这里是我的代码。

这是API路径和模型在相同的文件api objects。 api.js

const mongoose = require('mongoose'); 
const express = require('express'); 
const router = express.Router(); 

// MongoDb URL 

const dbHost = 'mongodb://localhost/motiva'; 

//conectamos la BD 

mongoose.connect(dbHost, function(err) { 
    if(err){ 
    console.log('No nos podemos conectar a la BD') 
    }else { 
    console.log('Conexion Exitosa') 
    } 
}); 

// Creamos el Schema de la BD 

const applicantSchema = new mongoose.Schema({ 
workbefore: {type:String, enum: ['Yes', 'No']},

您需要设置middleware从req.body获取数据。我在代码中没有看到任何中间件设置。

1）把下面的代码来设置中间件

var bodyParser = require('body-parser'); 
var app = express(); 
var urlencoded_body_parser = bodyParser.urlencoded({ 
    extended: true 
}); 

app.use(bodyParser.json()); 
app.use(urlencoded_body_parser); 

2）添加控制台登录后/applicants端点

console.log(req.body); 

3）如果你在控制台上的数据，该数据应基于你已经完成的映射成功地坚持在MongoDB上
