无法 GET 到 Node js 和 Express.js 中的路由

Question

我正在学习 Node.js 和 Express.js。
我正在尝试制作一个返回 JSON 对象的简单 API，但是当访问 URL localhost:4000/api/books ，我收到消息：无法获取 /api/books 。

 const express = require('express'); const app = express(); const bookRouter = express.Router(); const port = process.env.PORT || 3500; bookRouter.route('/books'); bookRouter.get((res, req) =>{ const response = {Title: 'This is my API', Author: 'XXXX'}; res.json(response); }); app.use('/api',bookRouter); app.listen(port, () => { console.log(`Running on port ${port}`); });

Answer 1

尝试这个：

const express = require('express');

const app = express();
const bookRouter = express.Router();
const port = process.env.PORT || 3500;


bookRouter.get('/books', (res, req) =>{
    const response = {Title: 'This is my API', Author: 'XXXX'};
    res.json(response);
  });

app.use('/api',bookRouter);

app.listen(port, () => {
  console.log(`Running on port ${port}`);
});
