orchardcms - Orchard CMS - 在 API 调用中返回 HTML

Question

我在 Orchard CMS (1.10) 中创建了一个自定义模块，它公开了一个 API 端点。我想公开一个 Get 调用，如果我传递内容项的 ID，它会返回该内容项的 Html。

我也想知道如何在 API 调用中返回页面布局 html？

谢谢

我认为这是你需要的：

public class HTMLAPIController : Controller {
    private readonly IContentManager _contentManager;
    private readonly IShapeDisplay _shapeDisplay;
    private readonly IWorkContextAccessor _workContextAccessor;

    public HTMLAPIController(
        IContentManager contentManager,
        IShapeDisplay shapeDisplay,
        IWorkContextAccessor workContextAccessor) {
        _contentManager = contentManager;
        _shapeDisplay = shapeDisplay;
        _workContextAccessor = workContextAccessor;
    }

    public ActionResult Get(int id) {
        var contentItem = _contentManager.Get(id);

        if (contentItem == null) {
            return null;
        }

        var model = _contentManager.BuildDisplay(contentItem);

        return Json(
            new { htmlString = _shapeDisplay.Display(model) }, 
            JsonRequestBehavior.AllowGet);
    }

    public ActionResult GetLayout() {
        var layout = _workContextAccessor.GetContext().Layout;

        if (layout == null) {
            return null;
        }

        // Here you can add widgets to layout shape

        return Json(
            new { htmlString = _shapeDisplay.Display(layout) }, 
            JsonRequestBehavior.AllowGet);
    }
}

我很确定您要问的正是 in 的Display方法ItemController在Orchard.Core.Contents.Controllers做什么：

public ActionResult Display(int? id, int? version) {
    if (id == null)
        return HttpNotFound();

    if (version.HasValue)
        return Preview(id, version);

    var contentItem = _contentManager.Get(id.Value, VersionOptions.Published);

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

    if (!Services.Authorizer.Authorize(Permissions.ViewContent, contentItem, T("Cannot view content"))) {
        return new HttpUnauthorizedResult();
    }

    var model = _contentManager.BuildDisplay(contentItem);
    if (_hca.Current().Request.IsAjaxRequest()) {
        return new ShapePartialResult(this,model);
    }

    return View(model);
}

视图的代码是这样的：

@using Orchard.ContentManagement
@using Orchard.Utility.Extensions
@{
    ContentItem contentItem = Model.ContentItem;
    Html.AddPageClassNames("detail-" + contentItem.ContentType.HtmlClassify());
}@Display(Model)
