我的代码如下所示:
app.js
const app = express();
const itemsRouter = require('./routes/items.js');
app.use(bodyParser.urlencoded({
extended: true
}));
app.use('/items', itemsRouter);
items.js
const router = require('express').router;
router.get('/itemTest', (req, res) => {
res.json({
sucess: true
});
console.log(`the parametrs are ${req.body.item_name} ${req.body.item_post}`);
});
module.exports = router;
但是在某种程度上,我无法让路由器正常工作,而且它说无法读取属性' get'未定义的。
错误堆栈如下所示:

答案 0 :(得分:4)
这里有两个问题:
express.Router
而不是express.router
。express.Router
的新实例(例如var router = new express.Router()
),而不是尝试直接将构造函数用作实例。
