go语言在linux网络编程

Go语言在Linux网络编程方面表现出色，它提供了丰富的库和API来处理网络相关的任务。以下是一些常见的Go语言网络编程场景和示例代码：

package mainimport ("bufio""fmt""net")func main() {// 监听端口listener, err := net.Listen("tcp", ":8080")if err != nil {fmt.Println("Error listening:", err)return}defer listener.Close()fmt.Println("Server is listening on port 8080...")for {// 接受客户端连接conn, err := listener.Accept()if err != nil {fmt.Println("Error accepting:", err)continue}// 处理客户端连接go handleConnection(conn)}}func handleConnection(conn net.Conn) {defer conn.Close()reader := bufio.NewReader(conn)for {message, err := reader.ReadString('\n')if err != nil {fmt.Println("Error reading:", err)break}fmt.Printf("Received: %s", message)}}

package mainimport ("fmt""net")func main() {// 连接到服务器conn, err := net.Dial("tcp", "127.0.0.1:8080")if err != nil {fmt.Println("Error connecting:", err)return}defer conn.Close()_, err = conn.Write([]byte("Hello, Server!\n"))if err != nil {fmt.Println("Error writing:", err)return}reader := bufio.NewReader(conn)message, err := reader.ReadString('\n')if err != nil {fmt.Println("Error reading:", err)return}fmt.Printf("Server response: %s", message)}

package mainimport ("fmt""net")func main() {// 创建UDP连接conn, err := net.DialUDP("udp", nil, &net.UDPAddr{IP: net.ParseIP("127.0.0.1"),Port: 8080,})if err != nil {fmt.Println("Error creating UDP connection:", err)return}defer conn.Close()_, err = conn.Write([]byte("Hello, UDP Server!"))if err != nil {fmt.Println("Error writing:", err)return}buffer := make([]byte, 1024)n, _, err := conn.ReadFromUDP(buffer)if err != nil {fmt.Println("Error reading:", err)return}fmt.Printf("Server response: %s", string(buffer[:n]))}

package mainimport ("fmt""io/ioutil""net/http")func main() {resp, err := http.Get("https://api.example.com/data")if err != nil {fmt.Println("Error making request:", err)return}defer resp.Body.Close()body, err := ioutil.ReadAll(resp.Body)if err != nil {fmt.Println("Error reading response body:", err)return}fmt.Printf("Response: %s", string(body))}

这些示例展示了如何使用Go语言在Linux上进行基本的网络编程，包括TCP和UDP通信以及HTTP请求。你可以根据自己的需求进行扩展和修改。
