Go 언어의 TCPF 프로토콜 구현에 대한 심층적인 이해

package main

import (
    "fmt"
    "net"
)

func main() {
    conn, err := net.Dial("tcp", "example.com:80")
    if err != nil {

        return
    }
    defer conn.Close()

    // 发送数据
    conn.Write([]byte("Hello, TCP Server!"))

    // 接收数据
    buffer := make([]byte, 1024)
    conn.Read(buffer)
    fmt.Println("Received:", string(buffer))
}

package main
