Mongodb连接数据库

//本地下载mongodb数据库（基本不用配置）,安装express ，mongoose包
const express = require("express")
const app = express()
const bodyparser = require('body-parser');
//var jsonParser = bodyparser.json();   //json数据类型
const { User } = require("./models")
app.use(bodyparser.urlencoded({ extended: false }));   //接收 x-www-form-urlencoded 参数

models.js
const mongoose = require("mongoose")
mongoose.connect("mongodb://localhost:27017/express-auth") //express-auth项目文件名 默认端口27017
const UserSchema = new mongoose.Schema({
    email: { type: String, unique: true },   //字段唯一
    name: { type: String },
    password: {
        type: String,
        set(val) {
            return require('bcrypt').hashSync(val, 10);  //密码加密
        }
    },
    indetity: { type: String }
})
const User = mongoose.model('User', UserSchema)
// User.db.dropCollection('users')
module.exports = { User }

//apifox接口工具
//获得user表
app.get('/users', async (req, res) => {
    const users = await User.find()
    res.send({ users })
})
//注册表
app.post('/api/register', async (req, res) => {
    const user = await User.create({
        email: req.body.email,
        name: req.body.name,
        password: req.body.password,
        indetity: req.body.indetity
    })
    res.send(user)
})

接口工具踩坑 apifox

在传参的时候 req.body里数据一直为空 后发现传的格式有问题 需引入body-parser模块 在传 x-www-form-urlencoded 参数时需要 并全局引入 app.use(bodyparser.urlencoded({ extended: false }));

//传入json参数时
var jsonParser = bodyparser.json();  
app.get('/users',jsonParser,async (req, res) =>{····}
