Unity捕获Curl error 28的办法

Unity的UnityWebRequest如果设置了timeout，在超时后会有一个Curl error 28的报错，很是讨厌，强迫症患者可以用下面的办法过滤掉。

async private void Start()
{
    
    
	UnityWebRequest unityWeb;
	unityWeb = new UnityWebRequest(url, "Get");
	unityWeb.downloadHandler = new DownloadHandlerBuffer();
	//unityWeb.timeout = 3;
	
	var taskget = unityWeb.SendWebRequest();
	await Task.Delay(3000); 
	
	if (unityWeb.result != UnityWebRequest.Result.Success)
	{
    
    
		Debug.LogWarning("Http获取远程文件失败: " + unityWeb.result.ToString() + " , Url:" + url);
		loaderror = true;
	}

	unityWeb.Dispose();
}

核心思想就是不用timeout，直接3秒后就判断就是下载到了。
