MVC 4 路由映射不起作用

Question

我有一个最近添加了文件附件功能的网站；然而，剑道.SaveUrl() 似乎没有“看到”控制器！我已经验证所有文件路径都是正确的。我在默认映射语句之前添加了自定义映射...浏览器不是问题，我尝试过 IE、Chrome、FireFox 和 Safari，同样的错误。请帮忙！

错误：

System.Web.HttpException (0x80004005): The controller for path '/Shared/RepairAttachment' was not found or does not implement IController.

Global.asax.cs 中的地图：

        routes.MapRoute(
            name: "/Shared/RepairAttachment",
            url: "Controllers/RepairAttachmentsController/{Save}/{IEnumerable<HttpPostedFileBase>}",
            defaults: new { controller = "RepairAttachmentsController", action = "Save", attachments = UrlParameter.Optional });

文件上传器代码：

    @(Html.Kendo().Upload()
        .ShowFileList(true)
        .Async(async => async
            .SaveUrl("SharedRepairAttachment")
        )
        .Name("frmUploadController")
        .Multiple(true)
        .Events(events => events
            .Complete("onRepairAttachmentUploadComplete")
            .Error("onRepairAttachmentUploadError")
        )
    )

控制器（部分）：

public class RepairAttachmentsController : Controller
{
    [HttpPost]
    [HttpOptions]
    public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments)
    {
        try
        {
            HarbisonFischerDBEntities db = new HarbisonFischerDBEntities();
            foreach (var file in attachments)
            {
                Repair r = db.Repairs.Find(ViewBag.RepairID);
                // Each Customer and repair gets their own folder
                string srvrpath = Path.Combine(ConfigurationManager.AppSettings["ServerPathForFiles"].ToString(), r.CustomerLocation.Customer.OracleName);
                srvrpath = Path.Combine(srvrpath, r.RepairID.ToString());
                if (Directory.Exists(srvrpath) == false) { Directory.CreateDirectory(srvrpath); }

                string fileName = Path.GetFileName(file.FileName);  // Some browsers send file names with full path; we only care about the file name.
                string destinationPath = Path.Combine(Server.MapPath(srvrpath), fileName);
                file.SaveAs(destinationPath);

                RepairAttachment ra = new RepairAttachment();
                ra.FileName = file.FileName;
                ra.Title = Path.GetFileNameWithoutExtension(file.FileName);
                ra.RepairID = ViewBag.RepairID;
                db.RepairAttachments.Add(ra);
                db.SaveChanges();                
            }
        }
        catch (Exception ex)
        {
            Logic.ExceptionLogging.LogException("RepairAttachmentsController", ex, null, null);
            return Json(new { status = "Upload Failed: " + ex.Message }, "text/plain");
        }
        return Json(new { status = "Upload succeeded." }, "text/plain");
    }

我不知道剑道，但我很难认为这会奏效：

routes.MapRoute(
            name: "/Shared/RepairAttachment",
            url: "Controllers/RepairAttachmentsController/{Save}/{IEnumerable<HttpPostedFileBase>}",
            defaults: new { controller = "RepairAttachmentsController", action = "Save", attachments = UrlParameter.Optional });

如果您向“/Shared/RepairAttachment”发送请求，url 参数中的模式应与此匹配。所以，我希望你需要类似的东西

routes.MapRoute(
            name: "RepairAttachment",
            url: "/Shared/RepairAttachment",
            defaults: new { controller = "RepairAttachments", action = "Save", attachments = UrlParameter.Optional });

注意我的方式

• 更改了url 参数的值以匹配传入的请求
• 从“RepairAttachmentsController”中删除了“Controller”，因为除非您的控制器名为“RepairAttachmentsControllerController”，否则不需要它
• 完全删除了“{IEnumerable...}”内容。我知道您正试图告诉 MVC 您将发送一组文件，但您没有在这里声明。 MVC's model binding features 会自行解决，因为您的操作方法需要一个 IEnumerable<HttpPostedFileBase> attachments 参数。
