let headers:Array<any> = new Array<any>();
            headers.push("Content-Type", "application/json")
            //headers={"Content-Type":"application/json"}
            //let answers={"answers":core.CommonData.DaTi,"examUuid":network.HttpHelper.compile(core.CommonData.Uuid),"openId":network.HttpHelper.compile(core.CommonData.Uuid)}
            var xhr: Laya.HttpRequest = new Laya.HttpRequest();
            xhr.http.headers=headers
