今天苦战了一天,就跟一个Unity切换到web平台的socket通信出错苦苦纠缠了一天,问了好多大牛,但他们的回复都是我没搞过web平台下的通信或者我只专研于pc或者移动平台。看来没办法了,只能自己硬着头皮往下探究了,貌似之前flash开发就是这样,凡事碰到要跟服务器通信的都会出现老大难的权限不足的错误。
具体错误如下:
SecurityException: Unable to connect, as no valid crossdomain policy was found
System.Net.Sockets.Socket.Connect_internal (IntPtr sock, System.Net.SocketAddress sa, System.Int32& error, Boolean requireSocketPolicyFile)
System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP, Boolean requireSocketPolicy)
System.Net.Sockets.Socket.Connect (System.Net.EndPoint remoteEP)
System.Net.Sockets.UdpClient.DoConnect (System.Net.IPEndPoint endPoint)
System.Net.Sockets.UdpClient.Connect (System.Net.IPEndPoint endPoint)
System.Net.Sockets.UdpClient.Connect (System.String hostname, Int32 port)
这印象太深刻了,搞得我快吐血了,但这时终于搞定了,真欣慰。之前我写过一篇有关于www访问web服务器的相同的问题,但那个稍微好解决一点,只要参考着官方文档就能解决了,我在这之前也有解决过该类问题的博客,官方的文档是:http://docs.unity3d.com/Documentation/Manual/SecuritySandbox.html,虽然全是英文,但学搞IT的看不了英文还真的很蛋疼,谁叫老美IT发达的呢,希望什么时候,互联网上技术先进的博客或者论坛都是中文的,当然有点想当然了,如果真有那么一天不知道是什么时候呢?!只能期待,下面回归正题。
我创建的服务器是C#的控制台程序,在项目工程文件里面添加以下crossdomain.xml文件,然后打开843的端口,切记这个必须打开,不然就会报错,客户端是通过这个端口来查找配置文件的。然后在运行unity切换到web平台就不会报错了。
怎么打开843端口呢?
解决办法:我们在unity的安装目录下找到一个sockpol.exe的这个一个工具,具体路径是在“...\Unity\Editor\Data\Tools\SocketPolicyServer“路径下有sockpol.exe和它的源码。如果你的服务器端是Windows平台的话,直接Copy一个sockpol.exe到服务器端,在CMD中执行
sockpol.exe --all
即可为服务器端配置好Security SandBox安全策略。
运行了之后我们会看到Hit Return to stop the server,然后如果有一个人连接上的话就会提示
incoming connection
got policy request,sending response
如果做到这一步 恭喜你能连接了。

还有一个问题就是端口衍射的问题,要绑定外网IP和内网服务器的端口,不然的话外网还是不能使用聊天功能的,只能看到页面而已!
