如何修复节点 js 中的错误无效的 sec-WebSocket-Accept 标头?

Question

我正在尝试在节点js中创建客户端websocket。websocket 服务器在浏览器(火狐浏览器(中运行。代码和错误消息如下。它在浏览器中工作时在 Nodejs 中不起作用。这是什么原因呢？我该如何解决？

代码(节点 JS(：

const WebSocket = require('ws');
const { randomBytes } = require('crypto');
const headers = {
Accept: '*/*',
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'q=0.8,en-US',
'Cache-Control': 'no-cache',
Connection: 'keep-alive, Upgrade',
cookie: 'key=UE2BQmTF;',
Pragma: 'no-cache',
'Sec-WebSocket-Extensions': 'permessage-deflate',
'sec-websocket-key': randomBytes(16).toString('base64'),
'Sec-WebSocket-Version': '13',
Upgrade: 'websocket',
'User-Agent':
'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0',
};
ws = new WebSocket(wurl, { headers });
ws.binaryType = 'arraybuffer';
ws.on('open', () => {
console.log('connected', Date());
});
ws.on('close', () => {
console.log('disconnected', Date());
});

错误：

'sec-websocket-key' 由 ws 自动生成 sec-websocket-key
