无法获取/posts

Question

我正在尝试访问我的路由"posts.js"，但是当我启动服务器并连接到localhost:5000/post时。此错误显示为"Cannot GET/posts“

代码: server/routes/posts.js

import express from 'express';

import { getPost, createPost } from '../controller/posts.js'

const router = express.Router();

router.get('/', getPost);
router.post('/', createPost);

export default router;

代码:server/model/postMessages.js

import mongoose from 'mongoose';

const postSchema = mongoose.Schema({
    title: String,
    message: String,
    creator: String,
    tags: [String],
    selectedFile: String,
    likeCount: {
        type: Number,
        default: 0
    },
    createdAt: {
        type: Date,
        default: new Date()
    },
});

const PostMessage = mongoose.model('PostMessage', postSchema);

export default PostMessage;

代码: server/controller/posts.js

import PostMessage from '../models/postMessages.js'



export const getPost = async (req, res) => {
    try {
        const postMessages = await PostMessage.find();

        res.status(200).json(postMessages);
    } catch(error) {

        res.status(404).json({ message: error.message });

    }
};

export const createPost = (req, res) => {
    res.send('Posts creation');
};

并在启动服务器时在终端中显示以下内容

[nodemon] starting `node index.js`

Answer 1

您需要将router.get('/', getPost);更改为router.get('/posts', getPost);，因为现在它在'/‘上响应，但您希望它在'/posts’上响应

Answer 2

您需要为/posts定义一个路由。

在posts.js文件中，添加router.get('/posts', getPost);

import express from 'express';

import { getPost, createPost } from '../controller/posts.js'

const router = express.Router();

router.get('/', getPost);
router.get('/posts', getPost);
router.post('/', createPost);

export default router;
