WebSocket连接失败：连接建立时出错：net :: ERR_SSL_PROTOCOL_ERROR

Question

为什么我试图通过wss://连接到websocket时出现此错误，但似乎与ws://一起正常工作？

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) 

    ... 
}

服务器仅监听HTTP连接，所以你应该做一个连接时使用ws。 wss是 “的WebSocket安全” 这真的只是意味着通过HTTPS提供了一个WebSocket连接（TLS）

从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).
