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

Question

当我试图通过wss：//连接到WebSocket时，我为什么会得到这个错误，但是在ws：//上却没问题呢？

错误：

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

代码：

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)

    ...
}
