生活随笔
收集整理的這篇文章主要介紹了
Go websocket
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
先看客戶端網頁代碼
<html> <head></head> <body><script type="text/javascript">var sock = null;var wsuri = "ws://127.0.0.1:1234";window.onload = function() {console.log("onload");sock = new WebSocket(wsuri); //創建新的websocketsock.onopen = function() { //連接console.log("connected to " + wsuri);}sock.onclose = function(e) {console.log("connection closed (" + e.code + ")");}sock.onmessage = function(e) {console.log("message received: " + e.data);}};function send() {var msg = document.getElementById('message').value;sock.send(msg);};</script><h1>WebSocket Echo Test</h1><form><p>Message: <input id="message" type="text" value="Hello, world!"></p></form><button οnclick="send();">Send Message</button> </body> </html>下面是服務端的
package mainimport ("golang.org/x/net/websocket""fmt""log""net/http" )func Echo(ws *websocket.Conn) {var err errorfor {var reply stringif err = websocket.Message.Receive(ws, &reply); err != nil {fmt.Println("Can't receive")break}fmt.Println("Received back from client: " + reply)msg := "Received: " + replyfmt.Println("Sending to client: " + msg)if err = websocket.Message.Send(ws, msg); err != nil {fmt.Println("Can't send")break}} }func main() {http.Handle("/", websocket.Handler(Echo))if err := http.ListenAndServe(":1234", nil); err != nil {log.Fatal("ListenAndServe:", err)} }
