kindedit,uedit 上传跨域返回

1.kindedit 跨域上传图片的时候，a.com 上传到b.com接收图片服务器，然后返回图片地址。

2.一般如果不做任何处理是获取不到返回的信息的。原因是跨域了

3.所以一般在上传成功后，在跳转回a.com的域名下。

下面为b.com接收图片处理后返回数据

  public void UploadLoanWay()
        {

            PostResult result = new PostResult();
            try
            {
                string time = DateTime.Now.ToString("yyyyMMdd");
                string path = CreateMktFolder(time);
                var fileInfo = CreateFile(path, null);
                string filename = fileInfo.FileName + "." + fileInfo.Extension;
                result.Status = 1;
                result.FileName = time + "/" + filename;
                System.Drawing.Image myImage = System.Drawing.Image.FromFile(Path.Combine(path, filename), true);
                result.Width = myImage.Width;
                result.Height = myImage.Height;
            }
            catch
            {
                result.Status = 0;
                result.Message = "上传文件失败";
            }
            //Response.AddHeader("Content-Type", "text/html; charset=UTF-8");
            //Response.Write(JsonMapper.ToJson(hash));
            //Response.End();
            Response.Redirect("http://cms.mkt.99asm.com/Result.ashx?result=" + result.FileName);

        }

下面是a.com获取b.com 返回的信息 这样就能够获取到返回的信息了

  public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            Hashtable hash = new Hashtable();
            hash["error"] = 0;
            var result = context.Request["result"];
            //当然这里最好判断一下result是否安全，不要接收到内容就显示这样会被人利用。
            if (result != null)
            {
                hash["url"] = "http://static.neihanhongbao.com/MktEdit/" + result;
            }
            context.Response.AddHeader("Content-Type", "text/html; charset=UTF-8");
            context.Response.Write(JsonMapper.ToJson(hash));
            context.Response.End();
        }
