要搭建Golang的WebSocket,可以按照以下步驟進行操作:
net/http
和github.com/gorilla/websocket
包:import (
"net/http"
"github.com/gorilla/websocket"
)
Upgrade
函數,用于升級HTTP連接為WebSocket連接:var upgrader = websocket.Upgrader{
ReadBufferSize: 1024,
WriteBufferSize: 1024,
CheckOrigin: func(r *http.Request) bool {
// 允許跨域請求
return true
},
}
func Upgrade(w http.ResponseWriter, r *http.Request) (*websocket.Conn, error) {
conn, err := upgrader.Upgrade(w, r, nil)
if err != nil {
return nil, err
}
return conn, nil
}
func WebSocketHandler(w http.ResponseWriter, r *http.Request) {
conn, err := Upgrade(w, r)
if err != nil {
// 處理升級失敗的情況
return
}
// 在這里編寫你的邏輯代碼
// 關閉WebSocket連接
defer conn.Close()
}
func main() {
http.HandleFunc("/ws", WebSocketHandler)
http.ListenAndServe(":8080", nil)
}
以上就是搭建Golang WebSocket的基本步驟,你可以根據自己的需求在WebSocket處理函數中編寫具體的業務邏輯。
