[LayaAir 2.0]部署web后无法请求访问HTTP API接口数据，调试模式下可以访问获取

Access to XMLHttpRequest at 'http://192.168.3.70:8081/api/test?data=test' from origin 'http://192.168.3.70:8082' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

自己回复吧，我是这么解决的，在服务的API接口添加以下代码就可以了
//初始化
_config = new HttpSelfHostConfiguration(url);

//API路由
_config.Routes.MapHttpRoute(
"API Default",
"api/{controller}/{username}",
new { username = RouteParameter.Optional });

//这是重点，从配置文件的appsettings节点中读取跨域的地址
var cors = new EnableCorsAttribute("*", "*", "*");
_config.EnableCors(cors);
