Question

我有一个使用 ws nodejs 库在后端运行的 websocket 服务器。每当我尝试从客户端连接到它时，我都会收到此错误。

events.js:377
      throw er; // Unhandled 'error' event
      ^

Error: write EPROTO 4455222784:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332:

这是在服务器上运行的代码：

import { createServer } from "http"                                   
import { WebSocketServer } from "ws"                                  

const server = createServer()                                         
const wss = new WebSocketServer({ server })                           
                                                  
                                                                      
server.listen("8080", () => {                                         
    console.log("Server listening on port 8080")                      
})                                                                    
                                                                      
wss.on("connection", (ws, req) => {                                   
    ws.on("open", () => console.log("connection open"))               
    ws.on("close", () => console.log("connection closed"))                                                                       
})

客户端代码（Next.js）

import WebSocket from 'isomorphic-ws'                                   
import {useEffect} from 'react'                                         
                                                                         
const ws = new WebSocket("wss://localhost:8080/")                       
                                                                        
const Page = () => {                                                   
                                                                        
    useEffect(() => {                                                   
        ws.onopen = () => {                                             
            console.log("connection open")                              
        }                                                               
    })                                                                  
                                                                       
    return (                                                            
        <div>                                                           
        </div>                                                          
    )                                                                   
}                                                                       
export default Page

我还应该提到，在构建它时我必须更新 npm 和节点版本。这会导致问题吗？我该如何解决这个问题？

我又回头看了看。如果我连接到ws://localhost:808，它就可以工作
