问题描述

我看过类似的问题，但它们似乎无法回答我的问题.发送GET请求时出现404错误.我将路由器放在单独的文件中，然后在app.js中调用我的请求.

I have looked at similar questions and they don't seem to answer my problem. I am getting a 404 error when I send a GET request. I have my router in a separate file and then calling my requests in my app.js.

为此，我尝试使问题尽可能简单.这就是我所拥有的:

I've tried to make my issue as simple as possible for this. Here's what I have:

movie-server.js:

const express = require('express')
const movieRouter = express.Router();

movieRouter
    .route('/movies')
    .get((req, res) => {
        res.send('hello from movies')
    })
module.exports = movieRouter;

app.js:

const express = require('express')
const app = express()
const movieRouter = require('./Movies/movie-server')

app.get('/', (req, res) => {
    res.send('Hello, world!') // this GET request works when I call it in Postman
})

app.use('/movies', movieRouter) // this returns a 404 Not Found error

module.exports = app

这是我文件的结构:

我不确定我缺少什么?

推荐答案

您给出了两次/movies 路由，因此您的服务器将响应http://host:port/movies/movies

You are giving twice the /movies route, so your server will respond to http://host:port/movies/movies

movie-server.js 应该包含:

const express = require('express')
const movieRouter = express.Router();

movieRouter
    .route('/') // Do not repeat /movies here
    .get((req, res) => {
        res.send('hello from movies')
    })
module.exports = movieRouter;
