Question

我想要什么？

我正在尝试覆盖ItemController的Display方法（Orchard.Core.Contents.Controllers.ItemController），因此我可以根据Accept Header更改输出。

如果标题是“application / xml”，我想返回xml
如果标题是“application / json”，我想返回json
否则返回html（与默认的Display方法一样）

我做了什么？

我已经制作了ItemController的副本并将其放在我的自定义模块的Controller文件夹中。还在类上面添加了OrchardSuppressDependency属性。

[OrchardSuppressDependency("Orchard.Core.Contents.Controllers.ItemController")]
[Themed]
public class ItemController : Controller
{
    private readonly IContentManager _contentManager;

    public ItemController(IContentManager contentManager, IShapeFactory shapeFactory, IOrchardServices services)
    {
        _contentManager = contentManager;
        Shape = shapeFactory;
        Services = services;
        T = NullLocalizer.Instance;
    }

    dynamic Shape { get; set; }
    public IOrchardServices Services { get; private set; }
    public Localizer T { get; set; }

    // /Contents/Item/Display/72
    public ActionResult Display(int id)
    {
        var contentItem = _contentManager.Get(id, VersionOptions.Published);

        if (contentItem == null)
            return HttpNotFound();

        if (!Services.Authorizer.Authorize(Permissions.ViewContent, contentItem, T("Cannot view content")))
        {
            return new HttpUnauthorizedResult();
        }
        //@Todo change output
        dynamic model = _contentManager.BuildDisplay(contentItem);
        return View((object)model);

    }

结果

ShellRoute.cs中显示错误

{"The controller for path '/OrchardLocal/products/product-2' was not found or does not implement IController."}

我忽略了什么吗？或者这是错误的做法？

在Orchard中的自定义模块中覆盖ItemController
