Node.js 通过Sequelize（Express/NodeJS）访问mysql时出错

我正在尝试开始使用Sequelize。我面临着一些错误，虽然我发现并清除了其中的一些错误，但这一个我无法发现

项目结构：

Project
 -Client
 -Server
  --models
    ---index.js
    ---Sid.js
  --router
    ---routes
       ----signup.js
    ---index.js
  app.js

我的配置变量：

"Lexstart": {
  "dbConfig": {
     "driver": "mysql",
     "user": "root",
     "database": "sid1",
     "password": "sid1",
     "host": "127.0.0.1",
     "port": "3306"
  }
}

My models/index.js：

var fs        = require("fs");
var path      = require("path");
var Sequelize = require('sequelize');
var config    = require('config');  // we use node-config to handle environments

var dbConfig = config.get('Lexstart.dbConfig');

// initialize database connection
var sequelize = new Sequelize(
    dbConfig.database,
    dbConfig.username,
    dbConfig.password,{
      host: dbConfig.host,
      dialect: dbConfig.driver
}
);
var db        = {};

fs
.readdirSync(__dirname)
.filter(function(file) {
    return (file.indexOf(".") !== 0) && (file !== "index.js");
})
.forEach(function(file) {
    var model = sequelize.import(path.join(__dirname, file));
    db[model.name] = model;
});

Object.keys(db).forEach(function(modelName) {
if ("associate" in db[modelName]) {
    db[modelName].associate(db);
}
});

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

模型/Sid.js

module.exports = function(sequelize, DataTypes) {
    var Sid = sequelize.define("Sid", {
        username: DataTypes.STRING,
        password: DataTypes.STRING
     });

return Sid;
};

我的路由器/index.js

/**
* The Index of Routes
*/

module.exports = function (app) {

// The signup route
app.use('/signup', require('./routes/signup'));
}

我的路由器/routes/signup.js

var models = require('../../models');
var Sid = models.Sid;
// Include Express
var express = require('express');
// Initialize the Router
var router = express.Router();
var config    = require('config');  // we use node-config to handle environments


// Setup the Route
router.get('/', function (req, res) {

Sid.findAll().then(function(users) {
    console.log(users);;
});

// return a json response to angular
res.json({
    'msg': users
});
});

router.get('/sid', function (req, res) {

// return a json response to angular
res.json({
    'msg': "sid"
});
});



// Expose the module
module.exports = router;

路由localhost:3000/signup/sid工作正常。但是/signup正在放弃错误。正如您在下面的错误文本中所看到的，它显示正在尝试连接，但没有配置提供的变量值（用户名、密码、主机）（配置变量工作正常，抓取正常）。我在调试时也无法理解这一点

数据库配置中没有用户名。 在配置中将用户替换为用户名。

“dbConfig”：{
“驱动程序”：“mysql”，
“用户”：“根用户”，
...
var sequelize=新的sequelize(
dbConfig.database，
dbConfig.用户名，

转到config.json，将用户更改为用户名，然后重新启动应用程序。有时不会出现错误，应用程序无法正常工作

"Lexstart": {
  "dbConfig": {
     "driver": "mysql",
     "username": "root",
     "database": "sid1",
     "password": "sid1",
     "host": "127.0.0.1",
     "port": "3306"
  }
}
