Unity3D 通过 http 方式 ， 访问 go http server 的 例子

Unity部分：

新建个脚本，挂在随便一个object下面。代码如下：

using UnityEngine;
using System.Collections;
using System.Text;

public class TestScript : MonoBehaviour
{
    public string url = "http://127.0.0.1:8000/test";
public string test_string;
// Use this for initialization
IEnumerator Start ()
{
    WWW www = new WWW (url);
    yield return www;

    print (www.bytes);
    test_string = System.Text.Encoding.UTF8.GetString (www.bytes);
    print (test_string);
}

// Update is called once per frame
void Update ()
{

}
}

go部分

<!-- lang: cpp -->
package main

import (
    "fmt"
    "html/template"
    "net/http"
)

func main() {
    fmt.Printf("Server Start\n")

    http.Handle("/img/", http.FileServer(http.Dir("tpl")))

    http.HandleFunc("/", NotFoundHandler)
    http.HandleFunc("/index", IndexHandler)
    http.HandleFunc("/test", TestHandler)
    http.ListenAndServe(":8000", nil)

    fmt.Printf("Server Closed\n")
}

func NotFoundHandler(w http.ResponseWriter, r *http.Request) {
    if r.URL.Path == "/" {
        http.Redirect(w, r, "/index", http.StatusFound)
    }

    t, e := template.ParseFiles("tpl/html/404.html")
    if e != nil {
    ErrorLog(e)
    }

    t.Execute(w, nil)
}

func TestHandler(w http.ResponseWriter, r *http.Request) {
    // below for test
    fmt.Println("PostForm", r.PostForm)
    test := r.PostForm.Get("test")
    fmt.Println("test string:", test)
    // upside for test

    returnString := "返回测试数值!"
    returnBytes := []byte(returnString)
    i, e := w.Write(returnBytes)
    fmt.Println("i,e:", i, e)
}

func IndexHandler(w http.ResponseWriter, r *http.Request) {
    t, e := template.ParseFiles("tpl/html/index.html")
    if e != nil {
    ErrorLog(e)
    }

    t.Execute(w, nil)
}

func ErrorLog(e error) {
    fmt.Println(e)
}
