Golang服务器，Unity客户端 通信

编辑器有：
1、 liteIDE
2、Sublime Text 2
3、Google Go language IDE built using the IntelliJ Platform
这个是需要手动配置的！
下面就介绍三种 通信的例子：
一、Unity 客戶端與 Golang 伺服器做通信
服务器执行结果
Unity客户端执行结果
程序代码：
//----------------------------------- Unity C# 客戶端
using UnityEngine;
using System.Collections;
using System.Net.Sockets;
using System.IO;
public class Server1 : MonoBehaviour
{
readonly string _ip = "127.0.0.1"; // 改为自己对外的 IP
readonly int _port = 1024;
void OnGUI()
{
if (GUI.Button(new Rect(10, 10, 100, 100), "Send Public IP"))
{
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Connect(_ip, _port);
NetworkStream stream = new NetworkStream(socket);
StreamWriter sw = new StreamWriter(stream);
StreamReader sr = new StreamReader(stream);
sw.WriteLine("你好服务器，我是客户端。");
sw.Flush();
string st = sr.ReadLine();
print(st);
sw.Close();
stream.Close();
socket.Close();
}
}
}
//-------------------------------------- Golang , Go語言 伺服器
package main
import (
"bufio"
"net"
)
func main() {
listener, _ := net.Listen("tcp", ":1024")
println("启动服务器...")
for {
conn, _ := listener.Accept() // 持续监听客户端连接
go ClientLogic(conn)
}
}
func ClientLogic(conn net.Conn) {
// 从客户端接受数据
s, _ := bufio.NewReader(conn).ReadString('\n')
println("由客户端发来的消息：", s)
// 发送消息给客户端
conn.Write([]byte("东东你好\n"))
// 关闭连接
conn.Close()
}
二、上传图片给服务器(后端)，Server 使用 Golang
运行结果 ， 就是把内容 添加到了这里！
using UnityEngine;
using System.Collections;
public class Server2 : MonoBehaviour
{
// 编辑器赋值，图片要设置为 Advanced 并且选中 可读可写 (否则会失败)
public Texture2D t;
IEnumerator Start()
{
WWWForm wwwF = new WWWForm();
wwwF.AddBinaryData("file", t.EncodeToPNG(), "A.png");
WWW www = new WWW("http://127.0.0.1:8080/upload", wwwF);
yield return www;
print("Upload Finish !!");
}
}
// 以下為 Golang Web 伺服器
package main
import (
"io/ioutil"
"net/http"
"os"
)
func uploadHandle(w http.ResponseWriter, r *http.Request) {
file, head, _ := r.FormFile("file")
defer file.Close()
bytes, _ := ioutil.ReadAll(file)
ioutil.WriteFile(head.Filename, bytes, os.ModeAppend)
}
func main() {
http.HandleFunc("/upload", uploadHandle)
http.ListenAndServe(":8080", nil)
}
三、传参数给 Golang Web 服务器，并回传讯息给 Unity
执行结果：
Golang Server code
package main
import (
"fmt"
"net/http"
)
func loadin(w http.ResponseWriter, r *http.Request) {
username := r.FormValue("username")
password := r.FormValue("password")
fmt.Fprintf(w, "<html><body>")
fmt.Fprintf(w, "Hello, %s ! <br/>", username)
fmt.Fprintf(w, "Your password is : %s!", password)
fmt.Fprintf(w, "</body></html>")
}
func main() {
http.HandleFunc("/loadin", loadin)
http.ListenAndServe(":8080", nil)
}
Unity C# code
using UnityEngine;
using System.Collections;
public class Server3 : MonoBehaviour
{
IEnumerator Start()
{
WWWForm wwwF = new WWWForm();
wwwF.AddField("username", "Loli");
wwwF.AddField("password", "Kitty");
WWW www = new WWW("http://127.0.0.1:8080/loadin", wwwF);
yield return www;
print(www.text);
}
}
