如何使用Javascript检索zip文件

Question

我的Asp Web Api控制器中有以下代码

public HttpResponseMessage Download(RequestModel model)
        {
            HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);

            string dataPath = System.Web.Hosting.HostingEnvironment.MapPath("~/App_Data");
            AttachmentsHelper attachmentsHelper = new AttachmentsHelper(model, dataPath);
            string attachmentsFile = attachmentsHelper.GetAttachments();

            response = Request.CreateResponse(HttpStatusCode.OK);
            response.Content = new StreamContent(new FileStream(attachmentsFile, FileMode.Open, FileAccess.Read));
            response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
            response.Content.Headers.ContentDisposition.FileName = "photos";
            response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue(MediaTypeNames.Application.Octet);
            return response;
        }

当我通过Ajax请求此方法时，我得到的结果在我的FireBug中看起来很奇怪
