我有一個(gè)簡單的 go web 服務(wù)器，它在端口 localhost:8080 上提供一個(gè)公共文件夾，其中包含一個(gè) html 文件以及一個(gè)帶有 websocket 邏輯的客戶端腳本。在我的main.go 文件中l(wèi)istener, err := net.listen("tcp", "localhost:8080")if err != nil { log.Fatal(err)}//full code in gist https://gist.github.com/Kielan/98706aaf5dc0be9d6fbe然后在我的客戶端腳本中try { var sock = new WebSocket("ws://127.0.0.1:8080"); console.log("Websocket - status: " + sock.readyState); sock.onopen = function(message) { console.log("CONNECTION opened..." + this.readyState); //onmessage, onerr, onclose, ect...}我在 chrome 中遇到錯(cuò)誤WebSocket connection to 'ws://127.0.0.1:8080/' failed: Error during WebSocket handshake: Unexpected response code: 200和火狐Firefox can't establish a connection to the server at ws://127.0.0.1:8080/.我發(fā)現(xiàn)這篇文章指的是 node.js 指示將 /websocket 添加到我的客戶端 websocket 字符串，盡管它沒有解決問題并導(dǎo)致 404我認(rèn)為響應(yīng)代碼 200 很好，我是否需要以某種方式將請求轉(zhuǎn)換為 websocket，也許它默認(rèn)為 http？如果是這樣，我該怎么做？

就像 JimB 指出的那樣，您還沒有處理 http 或 websocket 連接。
您可以使用包進(jìn)行 websocket 處理github.com/gorilla/websocket 這是一個(gè)簡單的設(shè)置：
package main
import (
"log"
"net/http"
"github.com/gorilla/websocket"
)
// wsHandler implements the Handler Interface
type wsHandler struct{}
func main() {
router := http.NewServeMux()
router.Handle("/", http.FileServer(http.Dir("./webroot"))) //handles static html / css etc. under ./webroot
router.Handle("/ws", wsHandler{}) //handels websocket connections
//serving
log.Fatal(http.ListenAndServe("localhost:8080", router))
}
func (wsh wsHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
// upgrader is needed to upgrade the HTTP Connection to a websocket Connection
upgrader := &websocket.Upgrader{
ReadBufferSize: 1024,
WriteBufferSize: 1024,
}
//Upgrading HTTP Connection to websocket connection
wsConn, err := upgrader.Upgrade(w, r, nil)
if err != nil {
log.Printf("error upgrading %s", err)
return
}
//handle your websockets with wsConn
}
在您的 Javascript 中，您var sock = new WebSocket("ws://localhost/ws:8080");顯然需要
