运行一个 node.js 程序，它在我的本地计算机上对快速服务器运行进行提取调用

Question

我如何运行 node.js 中的 javascript 程序对本地机器上的服务器运行进行本地获取调用？

我有一个本地 express 服务器正在侦听端口 4001：

const express = require('express');
const app = express();  

const PORT = process.env.PORT || 4001;

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

app.use('/test', (req, res, next) => {
    res.send('test');
})

我有一个单独的 app.js 文件，可以 node-fetch 调用此服务器：

const fetch = require('node-fetch');

const payload = fetch('https://localhost:4001/test');

payload.then(response => response.json())
.then(jsonResponse => {
    console.log(jsonResponse);
}).catch(error => {
    console.log(error);
})

运行 node app.js 在终端中导致以下错误消息：

FetchError: request to https://localhost:4001/test failed, reason: write EPROTO
15088:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:c:\ws\dep

Answer 1

根据协议 (EPROTO) 错误，考虑到其 localhost:

，请尝试将 http 而不是 https 作为目标

const fetch = require('node-fetch');

const payload = fetch('http://localhost:4001/test');

payload.then(response => response.json())
.then(jsonResponse => {
    console.log(jsonResponse);
}).catch(error => {
    console.log(error);
})

除非您创建了某种根 SSL 证书并将该证书添加到您的计算机。
