Question

我正在学习Node.js和Express.js。
我试图制作一个返回JSON对象的简单API，但是当访问URL localhost:4000/api/books时，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

尝试一下：

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}`);
});

无法获取到Node js和Express.js中的路由
