WebSocket连接失败：连接建立错误：net :: ERR_SSL_PROTOCOL_ERROR

Question

为什么在尝试通过wss://连接到websocket时出现此错误，但似乎与ws://一起使用？

错误

WebSocket connection failed: Error in connection establishment: net::ERR_SSL_PROTOCOL_ERROR

码

package main

import (
    "fmt"
    "log"
    "net/http"
    //"encoding/json"
    "github.com/gorilla/websocket"
)

var clients map[*websocket.Conn]*Client

var upgrader = websocket.Upgrader{
    CheckOrigin : func(r *http.Request) bool{
        return true
    },
}

type Client struct{
    session_id  string
    block_id    uint
    module      string
}

func main(){
    var port uint = 8000

    http.HandleFunc("/", handleConnections)

    log.Printf("Websocket server started on: %d", port)
    err := http.ListenAndServe(fmt.Sprintf(":%d", port), nil)
    if err != nil {
        log.Fatal("ListenAndServe: ", err)
    }
}

func handleConnections(w http.ResponseWriter, r *http.Request){
    //  Upgrade initial GET request to a websocket
    ws, err := upgrader.Upgrade(w, r, nil)
    if err != nil {
        log.Print(err)

        return
    }

    defer ws.Close()

    log.Print("Connection established to IP: ", r.RemoteAddr)

    ...
}

您的服务器仅侦听HTTP连接，因此您在建立连接时应使用ws。 wss是“WebSocket Secure”，它实际上只是指通过HTTPS（TLS）提供的WebSocket连接

来自RFC 6455

A |wss| URI identifies a WebSocket server and resource name and
indicates that traffic over that connection is to be protected via
TLS (including standard benefits of TLS such as data confidentiality
and integrity and endpoint authentication).
