本教程构建了基本的WebSocket服务器和客户端:
>客户与服务器交互的客户
安装大猩猩Websocket软件包:
<code>websocket-server/ ├── main.go # Application entry point ├── handlers/ # WebSocket handler functions │ └── websocket.go # Handles WebSocket connections and messages ├── static/ # Client-side HTML/JS files │ └── index.html # Simple client interface └── go.mod # Go module file</code>
>步骤1:
<code class="language-bash">go get -u github.com/gorilla/websocket</code>
main.go
这设置了HTTP服务器,提供静态文件,并在步骤2:websocket处理程序(main.go
)
<code class="language-go">package main import ( "fmt" "log" "net/http" "websocket-server/handlers" ) func main() { http.HandleFunc("/ws", handlers.HandleWebSocket) http.Handle("/", http.FileServer(http.Dir("./static"))) port := ":8080" fmt.Printf("Server running on http://localhost%s\n", port) log.Fatal(http.ListenAndServe(port, nil)) }</code>
>目录中,创建/ws
:
websocket.go
这个处理程序升级HTTP连接,读取消息并回声。
handlers
消息处理websocket.go
<code class="language-go">package handlers import ( "fmt" "net/http" "github.com/gorilla/websocket" ) var upgrader = websocket.Upgrader{ CheckOrigin: func(r *http.Request) bool { return true }, } func HandleWebSocket(w http.ResponseWriter, r *http.Request) { conn, err := upgrader.Upgrade(w, r, nil) if err != nil { fmt.Println("Upgrade failed:", err) return } defer conn.Close() fmt.Println("Client connected") for { _, msg, err := conn.ReadMessage() if err != nil { fmt.Println("Read failed:", err) break } fmt.Printf("Received: %s\n", msg) if err := conn.WriteMessage(websocket.TextMessage, msg); err != nil { fmt.Println("Write failed:", err) break } } }</code>
>
)HandleWebSocket
index.html
。 然后,在浏览器中打开index.html
(随附适当的客户端JavaScript)。
本教程使用大猩猩演示了基本的GO Websocket服务器。 WebSocket是实时应用程序的理想选择。 根据需要通过身份验证,广播和数据存储扩展此基础。
