Node.js 使用sequelize POST方法在nodejs中插入新记录

我想使用sequelize express在数据库中插入新数据，无需查询。我很努力，但是我没有得到结果。。。如果我的代码是错误的，那么给我一个使用sequelize express在db中插入新记录的代码

const Sequelize = require('sequelize');
var express = require('express');
var app = express();
var mysql = require('mysql');
//var request=require('request')
const sequelize = new Sequelize('ganeshdb', 'root', 'welcome123$', {
    host: 'localhost',
    port: 3306,
    dialect: 'mysql'
});
var users = sequelize.define('users', {
    id: {
        primaryKey: true,
        type: Sequelize.INTEGER,
    },
    name: Sequelize.STRING,
    role: Sequelize.STRING,
    email: Sequelize.STRING
});
app.post('/test', function (request, response) {
    return users.create({
        name: request.body.name,
        role: request.body.role,
        email: request.body.email
    }).then(function (users) {
        if (users) {
            response.send(users);
        } else {
            response.status(400).send('Error in insert new record');
        }
    });
});
app.listen(3000, function () {
    console.log('Express server is listening on port 3000');
});

你应该使用body pareser

示例使用主体解析器：

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

var app = express()

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

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

app.use(function (req, res) {
  res.setHeader('Content-Type', 'text/plain')
  res.write('you posted:\n')
  res.end(JSON.stringify(req.body, null, 2))
})

例如：

const Sequelize = require('sequelize');
const express = require('express');
const bodyParser = require('body-parser');

const app = express();

app.use(bodyParser.json({ limit: '100mb' }));
app.use(bodyParser.urlencoded({ extended: true, limit: '100mb', parameterLimit: 1000000 }));

const sequelize = new Sequelize('test_01', 'root', 'root', {
    host: 'localhost',
    port: 3306,
    dialect: 'mysql'
});

const users = sequelize.define('users', {
    id: {
        primaryKey: true,
        type: Sequelize.INTEGER,
    },
    name: Sequelize.STRING,
    role: Sequelize.STRING,
    email: Sequelize.STRING
});

app.post('/test', function (request, response) {
    return users.create({
        id: request.body.id,
        name: request.body.name,
        role: request.body.role,
        email: request.body.email
    }).then(function (users) {
        if (users) {
            response.send(users);
        } else {
            response.status(400).send('Error in insert new record');
        }
    });
});

app.listen(3001, function () {
    console.log('Express server is listening on port 3000');
});

有什么错误吗？你能在create函数中添加一个

.catch（（err）=>{console.log（err）}）

块并发布我们的错误，如果它是logscan，请给我一个完整的代码，实际上我是nodejs的新手，我的回答对你有帮助吗？是的，先生，你能帮我一个忙吗。。我想通过像路由、模型、控制器这样的单独文件插入数据。。我在互联网上看到了更多的例子，但没有得到正确的输出。先生，请提供您的邮件id，我将使用我的projectuladzislau。vavilau@gmail.com
