服务器无法处理请求

Question

client_side:

    <script>
        const name = localStorage['name']
        async function getUsers() {
            const page = document.querySelector('.page')
            const res = await fetch('http://localhost:3000/users')
            for(const name in res.usersName) {
                let userDiv = document.createElement('div')
                userDiv.innerHTML = name
                userDiv.style.textAlign = "center"
                page.append(div)
            }
        }
        getUsers()
    </script>
    </script>

server_side:

    const express = require('express')
    const app = express()
    const server = createServer(app).listen(3000)
    /*
    BODY: all of the routs 
    */
    /*this is where I get the error when I try to make a GET request to this rout
      it sends me 404 status error
    */
    app.get('users', (req, res) => {
     const usersName = new Array()
     console.log(req)
     for(const user of users) {
        usersName.push(user.name)
     }
     res.json({ usersName })
    })

当我向 API/users 路由发出 GET 请求时，我在 client_side 控制台中收到此错误消息：

home:27 GET http://localhost:3000/users 404 (Not Found)

我不知道为什么有人能帮忙

Answer 1

你忘了把 / 放在 `users' 之前。

app.get('/users', (req, res)=>{
    //your code block here
})
