1.自訂過濾器屬性public class NoCacheAttribute : FilterAttribute, IActionFilter{    public void OnActionExecuted(ActionExecutedContext filterContext)    {        //設定瀏覽器緩衝        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);        //設定介面跨域        filterContext.HttpContext.Response.AddHeader("Access-Control-Allow-Origin","*");    }    public void OnActionExecuting(ActionExecutingContext filterContext)    {    }}或者context.Response.ClearHeaders(); context.Response.AppendHeader("Access-Control-Allow-Origin","*"); string requestHeaders = context.Request.Headers["Access-Control-Request-Headers"]; context.Response.AppendHeader("Access-Control-Allow-Headers", string.IsNullOrEmpty(requestHeaders) ? "*" : requestHeaders); context.Response.AppendHeader("Access-Control-Allow-Methods", "POST, OPTIONS"); 2.web.config檔案裡配置<system.webServer>    <httpProtocol>     <customHeaders>       <add name="Access-Control-Allow-Methods" value="OPTIONS,POST,GET"/>       <add name="Access-Control-Allow-Headers" value="x-requested-with"/>       <add name="Access-Control-Allow-Origin" value="*" />     </customHeaders>   </httpProtocol> </system.webServer>
