还记得之前的单机游戏<<野乱三国>> 吗，本来是佛系做游戏的思路，能赚多少算多少，没想到最近好多人来破解支付了，不得已加了一个Http服务器来进行二次支付的验证，希望对有需要的人有所帮助。
服务器搭建
说明:目前百度的基本上都是java或者php的版本比较多，我们这里由于是unity的客户端所以也就用了c#来进行搭建。
原理：服务器本身很简单，一个监听客户端的链接，然后处理客户端传递的苹果返回的参数，然后拿去做二次验证，这个流程不太清楚的自己百度。
代码说明：此代码是我在GitHub上获取的国外的一个哥们写的，稍微改了下端口就，然后基本上就可以用了。

说明：这里中文注释的地方是需要你去处理的内容，也就是进行二次验证的地址，然后通知客户端发放奖励等等
客户端传递参数并发放奖励
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class HttpClient : MonoBehaviour {
// Use this for initialization
void Start () {
TestHttpSend();
}
// Update is called once per frame
void Update () {
}
public void TestHttpSend()
{
//测试POST方法
WWWForm form = new WWWForm();
form.AddField("string", "苹果回执的参数，准备上传到服务器");
StartCoroutine(SendPost("http://你的ip或者域名:8889/", form));
}
IEnumerator SendGet(string _url)
{
WWW getData = new WWW(_url);
yield return getData;
if (getData.error != null)
{
Debug.Log(getData.error);
}
else
{
Debug.Log(getData.text);
}
}
IEnumerator SendPost(string _url, WWWForm _wForm)
{
WWW postData = new WWW(_url, _wForm);
yield return postData;
if (postData.error != null)
{
Debug.Log(postData.error);
}
else
{
Debug.Log(postData.text);
}
}
}
发布到服务器上
说明：服务器的代码我发现了几个发布的问题，不过可能你不一定会遇到。
发布的时候需要验证而发布不了，可以参考提示的问题是
签名时出错，未找到SignTool.exe发布到云服务器安装后，提示程序终止问题CLR20R3 可以参考，不过我这里的代码是解决了的，原因就是在连接的时候需要添加trycatch 捕获异常，不然服务器不让运行
发布的程序在服务器上一闪而过，没任何提示，原因是你的端口被占用了，这里可以通过控制台查看下你的端口还有哪些没有被占用，然后选一个出来用即可指令：**netstat
-ano** 查看哪些被占用了 netstat -ano | findstr 端口号 查看某个端口的占用程序
