接收websocket请求的服务端：
package mainimport ( "fmt" "net/http" "github.com/gorilla/websocket")var upgrader = websocket.Upgrader{ ReadBufferSize:1024, WriteBufferSize: 1024,}func main() { http.HandleFunc("/echo", func(w http.ResponseWriter, r *http.Request) {conn, _ := upgrader.Upgrade(w, r, nil) // error ignored for sake of simplicityfor {// Read message from browsermsgType, msg, err := conn.ReadMessage()if err != nil {return}// Print the message to the consolefmt.Printf("%s sent: %s\n", conn.RemoteAddr(), string(msg))// Write message back to browserif err = conn.WriteMessage(msgType, msg); err != nil {return}} }) http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {http.ServeFile(w, r, "H:\\go\\main\\websockets.html") }) http.ListenAndServe(":8080", nil)}发送websocket请求的客户端：
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>WebSockets</title></head><body><input id="input" type="text" /><button onclick="send()">Send</button><pre id="output"></pre><script>var input = document.getElementById("input");var output = document.getElementById("output");var socket = new WebSocket("ws://localhost:8080/echo");socket.onopen = function () {output.innerHTML += "Status: Connected\n";};socket.onmessage = function (e) {output.innerHTML += "Server: " + e.data + "\n";};function send() {socket.send(input.value);input.valuehttps://www.huyubaike.com/biancheng/= "";}</script></body></html>【Go的网络编程详解】
