出现错误:
抛出新的TypeError('Router.use()需要中间件功能,但得到了'+ gettype(fn))v
我是新手,不确定发生了什么!任何帮助将不胜感激,如果有其他有用的信息,请告诉我。提前非常感谢!!!!!!!
这是我的app.js:
const express = require('express');
const app = express(); // object with methods; One method is router; express creates a server; app allows us to access the server; app.listen hooks up our server;
const morgan = require('morgan'); //app.use(...) morgan says console.log(wht app.use does);
const { db, Review, Toilet, User } = require('./server/db/index');
// Logger:
app.use(morgan('dev')); // implies '/' ('/', morgan('dev'));
//Body parser:
app.use(express.urlencoded({ extended: false }));
app.use(express.json());
// public:
app.use(express.static(__dirname + '/public'));
// Backend Routing:
app.use('/api', require('./server/api/index'));
// Setting up server
const PORT = process.env.PORT || 8880;
const syncDb = () => db.sync();
const startListening = () => {
app.listen(PORT, function() {
console.log(
` ***** I'm leisurely listening on pleasant port of ${PORT} *****`
);
});
};
async function bootApp() {
await syncDb();
await startListening();
}
bootApp();
这是我的服务器/api/index.js:
const router = require('express').Router();
router.use('/toilets', require('./toiletRoutes'));
router.use('/users', require('./userRoutes'));
router.use('/reviews', require('./reviewRoutes'));
module.exports = router;
这是我的服务器/db/api/toiletRoutes.js:
const express = require('express');
const router = express.Router();
const { Toilet, User, Review } = require('../db/index');
// Get all toilets
router.get('/', async function(req, res, next) {
console.log('in get all toilets');
try {
const allToilet = await Toilet.findAll();
res.status(200).send(allToilet);
} catch (error) {
next(error);
}
});
module.exports = router;

检查所有出口 应该是:
<img data-src="<?php echo $phone_image_value ?>" class="lazy-load" alt="<?php echo $phone_copy_value ?>">

您的index.js
位于sever/db/api/index.js
并且在您的app.js
中,您需要server/api/index.js
将其更改为正确的路径。
更新:
哦,我刚刚注意到了这部分
app.use(express.urlencoded({ extended: false }));
app.use(express.json());
应该是
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
您需要将body-parser
模块添加到依赖项中并需要它。
