向我的快递服务器发送请求返回错误

Question

Im just getting started with node and express and im trying to make a post request and push the results to an array for now. 我刚刚开始使用node和express，并试图发出一个发布请求并将结果立即推送到一个数组。 In the future i will be making these requests to a database, but for learning purposes i am doing this to an array now. 将来，我将向数据库发出这些请求，但出于学习目的，我现在对阵列进行此操作。 Getting responses works, post requests gives me an error in postman. 获取回复有效，发布请求使我在邮递员中出错。

const express = require('express');
const app = express(); 
const port = 5000;
const arr = []; 

app.use(express.json());

app.post('/' , (req,res) => {
    arr.push(req.body);
    res.send(arr);
})


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

Sadly the postman error doesnt tell me much. 不幸的是，邮递员的错误并没有告诉我太多。

The error : 错误：

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>Error</title>
    </head>
    <body>
        <pre>Cannot POST /</pre>
    </body>
</html>

The request : 要求：

{
"app" : "Post"
}

Specifications of requeSt : 要求规格：

content-length →140
content-security-policy →default-src 'none'

Answer 1

Actually you code is running in my machine, maybe you just forgot some postman configuration. 实际上，您的代码正在我的机器上运行，也许您只是忘记了一些邮递员配置。

content-type: application/json 内容类型：application / json
method: post 方法：发布
row data: {"data": "test"} 行数据：{“数据”：“测试”}
