Question

我使用ASP.NET MVC 4创建了一个博客。

问题是当我的网址不是localhost时我在帖子中看不到任何图片，因为它们的网址错误。帖子的网址可以是：

1。localhost/post/2015/4/name_of_post或

2. localhost/archive/name_of_post或

3. localhost/name_of_category/name_of_post，

并且帖子里面是图片。

图片必须有此

url:localhost/App_Files/Upload/name_of_image.jpg

但是改为

url：localhost/post/2015/4/App_Files/Upload/name_of_image.jpg或

localhost/archive/name_of_post或

localhost/name_of_category/App_Files/Upload/name_of_image.jpg。

如果您使用正确的网址，您将在浏览器中看到该图片。当我创建它时，我使用tinymce在帖子中添加图片。图片将另存为App_Files / Upload文件夹中的文件。该帖子在sql数据库中作为html插入行。我用这个routeConfig

routes.MapRoute(
"Post",
"Archive/{year}/{month}/{title}",
new { controller = "Blog", action = "Post" }
);

并且uploadController是这样的：

using HotNews.ViewModels;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace HotNews.Controllers
{
    public class UploadController : Controller
    {
        //
        // GET: /Upload/
        public ActionResult Index(string id)
        {
            //var url = HttpRuntime.AppDomainAppVirtualPath;
            var url = ConfigurationManager.AppSettings["BlogUrl"];
            return View(new UploadViewModel
            {
                baseUrl = url,
                track = id
            });
        }

        [HttpPost]
        public ActionResult UploadFile()
        {
            var file = Request.Files[0];
            if (file != null && file.ContentLength > 0)
            {
                var fileName = Path.GetFileName(file.FileName);
                var path = Path.Combine(Server.MapPath("~/App_Files/Upload"), fileName);
                file.SaveAs(path);
            }

            return RedirectToAction("Index");
        }

        public ActionResult ListFiles()
        {
            var fileData = new List<ViewDataUploadFileResults>();

            DirectoryInfo dir = new DirectoryInfo(Server.MapPath("~/App_Files/Upload"));
            if (dir.Exists)
            {
                string[] extensions = MimeTypes.ImageMimeTypes.Keys.ToArray();

                FileInfo[] files = dir.EnumerateFiles()
                                      .Where(f => extensions.Contains(f.Extension.ToLower()))
                                      .ToArray();

                if (files.Length > 0)
                {
                    foreach (FileInfo file in files)
                    {
                        // var baseurl = ConfigurationManager.AppSettings["BlogUrl"];
                        var relativePath = VirtualPathUtility.ToAbsolute("~/App_Files/Upload") + "/" + file.Name;

                        fileData.Add(new ViewDataUploadFileResults()
                        {
                            // url = baseurl+relativePath,
                            url = relativePath,
                            name = file.Name,
                            type = MimeTypes.ImageMimeTypes[file.Extension],
                            size = Convert.ToInt32(file.Length)
                        });
                    }
                }
            }

            return Json(fileData, JsonRequestBehavior.AllowGet);
        }
    }
}

我必须创建一个图像hanndler ??我必须创建一个新的routeconfig ??什么样的？

ASP.NET URL OF IMAGE不存在
