UnityVS: Web Target with Web Security enabled will prevent opening files and communication with UnityVS.
解决方法
直接在 unity中 File-》build setting -> 更换一个平台就行，不要选择web的
just go to File->Build Settings then select something other than web player and then press Switch Platform.

捕获日志
using UnityEngine;
using System.Collections;
public class SetupVerification : MonoBehaviour
{
public string message = "";
private bool badSetup = false;
void Awake ()
{
Application.RegisterLogCallback (OnLog);
}
void OnLog (string message, string stacktrace, LogType type)
{
if (message.IndexOf ("UnityException: Input Axis") == 0 ||
message.IndexOf ("UnityException: Input Button") == 0
)
{
//处理异常信息
}
}
}
===============================================================
InternalGetGameObject can only be called from the main thread.
然后socketclient对象是异步的，所以做了多线程处理，当socketclient接收到消息时，回调了主线程的函数（继承自monobehaviour），这时候就导致了报错。上面第一篇unity论坛博文解释得比较清楚，大概就是unity对于API调用主线程做了限制：
“Unity chose to limit API calls to main-thread, to make a simple and solid threading model that everyone can understand and use.”
