javascript - Express 中的路由 Controller 模型存在问题

Question

我在为我的路线创建驱动程序时遇到问题。由于某种原因，它无法识别 send() 属性。

这是我的路线代码:

const express = require('express');
const router = express.Router();
const Ctrl = require('../controllers/index');

/* GET home page. */
router.get('/', Ctrl.list());

module.exports = router;

这是我的 Controller 的代码:

const express = require('express');

Ctrl = {}

Ctrl.list = (req, res) => {
   res.send("sended");
}

module.exports = Ctrl;

当我使用传统函数(不是箭头函数)时，也会发生同样的情况。

另一方面，这是我的快速配置，其中配置的路由是:

const express = require('express');
const path = require('path');
const cookieParser = require('cookie-parser');
const logger = require('morgan');
const helmet = require('helmet');

const indexRouter = require('./routes/index');
const usersRouter = require('./routes/users');

const app = express();
require('./database/config');

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(helmet());

app.use('/', indexRouter);
app.use('/users', usersRouter);

module.exports = app;

我收到此错误:

E:\elarchivero\api\controllers\index.js:6 res.send("sended"); ^

您需要将路由器更改为函数引用而不是调用。

router.get('/', Ctrl.list);
