跨域调用 WcfRest

 公司项目需要有一个WcfRest服务接口，于是编写了一个 部署后发现，在跨域调用时会出现“not allowed by Access-Control-Allow-Origin”的错误提示，在gg和度娘的帮助下完美解决该问题

Wcf Global：

public class Global : HttpApplication
    {
        void Application_Start(object sender, EventArgs e)
        {
            RegisterRoutes();
        }
        protected void Application_BeginRequest(object sender, EventArgs e)
        {

            HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            HttpContext.Current.Response.Cache.SetNoStore();

            EnableCrossDmainAjaxCall();
        }
        private void EnableCrossDmainAjaxCall()
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods",
                            "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers",
                            "Content-Type, Accept");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age",
                            "1728000");
                HttpContext.Current.Response.End();
            }
        }

        private void RegisterRoutes()
        {
            // Edit the base address of Service1 by replacing the "Service1" string below
            RouteTable.Routes.Add(new ServiceRoute("", new WebServiceHostFactory(), typeof(Service)));
        }

Html：

<script type="text/javascript">
        function add(resId, resName, resUrl, goodsId,mid) {
            var strjson =
                {
                    resId: resId,
                    resName: resName,
                    resUrl: resUrl,
                    goodsId: goodsId,
                    mid:mid
                };
            var encode_Entity = $.toJSON(strjson);
            $.ajax({             url: "http://XXXXXX.XXXXXX.com/WcfRestService/Wardrobe/AddWardrobeRes/",
                type: "POST",
                dataType: "json",
                data: encode_Entity,
                contentType: "application/json; charset=utf-8",
                success: function (data) {
                    alert(data);
                },
                error: function (x, e) {
                }
            });
        }
    </script>
