C# 如何解决DNN自定义模块不渲染的问题？

我正在使用DNN9.3.2和Chris Hammond的模块模板来创建自定义模块。当我将模块加载到没有可见性限制的页面上时，它不会呈现。安装或呈现所述页面后，事件日志不包含任何错误

由于这是我的第一个DNN MVC模块，我认为这与我创建的以下控制器类有关：

    [DnnHandleError]
    public class SignupController : DnnController
    {
    // GET: Signup
    [ModuleAction(ControlKey = "Edit", TitleKey = "AddItem")]
    public ActionResult Index()
    {
        var signups = OnboardingManager.Instance.GetOnboardings(ModuleContext.ModuleId);
        return View(signups);
    }

    [HttpPost]
    [DotNetNuke.Web.Mvc.Framework.ActionFilters.ValidateAntiForgeryToken]
    public ActionResult Edit(Models.Onboarding onboarding)
    {
        ProPayService service = new ProPayService();

            OnboardingManager.Instance.CreateOnboarding(onboarding);
            service.MerchantSignupForProPayAsync();

            return RedirectToDefaultRoute();
    }

    public ActionResult Edit(int onboardingId = -1)
    {

     DotNetNuke.Framework.JavaScriptLibraries.JavaScript.RequestRegistration(CommonJs.DnnPlugins);

        var userlist = UserController.GetUsers(PortalSettings.PortalId);
        var users = from user in userlist.Cast<UserInfo>().ToList()
            select new SelectListItem { Text = user.DisplayName, Value = user.UserID.ToString() };

        ViewBag.Users = users;

        var onboarding = (onboardingId == -1) ? new Models.Onboarding{ModuleId = ModuleContext.ModuleId} : OnboardingManager.Instance.GetOnboarding(onboardingId, ModuleContext.ModuleId);
        return View(onboarding);

    }
}

我修改后的DNN清单如下所示：

当我构建解决方案时，它成功了，但我在Visual Studio 2019中确实收到了16条错误消息，大意是：

Error   CS0012  The type 'WebViewPage<>' is defined in an assembly that is 
not referenced. You must add a reference to assembly 'System.Web.Mvc, 
Version=5.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.  
1_desktopmodules_mvc_onboarding_Views_Signup_Index.cshtml    
C:\websites\dnndev.me\DesktopModules\Onboarding\Views\Signup\Index.cshtml   

错误CS0012类型“WebViewPage”是在以下程序集中定义的：
未引用。必须添加对程序集“System.Web.Mvc”的引用，
版本=5.1.0.0，区域性=中性，PublicKeyToken=31bf3856ad364e35'。
1_desktopmodules_mvc_Onboard_Views_Signup_Index.cshtml
C:\websites\dnndev.me\DesktopModules\onboard\Views\Signup\Index.cshtml

我已使用以下方法将上述程序集添加到模块视图文件夹中的web.config，以及C:\webs.dnndev.me中的主DNN web.config：

    <compilation debug="true" targetFramework="4.7.2">
  <assemblies>
    <add assembly="System.Web.Mvc, Version = 5.1.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35"/>
    <add assembly ="netstandard, Version = 2.0.0.0, Culture = neutral, PublicKeyToken = cc7b13ffcd2ddd51"/>
  </assemblies>
</compilation>

---

如何防止抛出错误并确保我的视图按需要呈现？

首先，确保您的模块是根据DNN实例所针对的.NET Framework的正确版本编译的。您可以在web.config文件中查找一行，类似于以下内容：

在DNN的最新版本中，您需要确保明确地告诉DNN您的控制器要响应的权限。注意下面示例中的

DnnModuleAuthorize

类装饰

使用系统；
使用System.Web.Mvc；
使用DotNetNuke.Entities.Modules；
使用DotNetNuke.Security；
使用DotNetNuke.Services.Exceptions；
使用DotNetNuke.Web.Mvc.Framework.ActionFilters；
命名空间SocialBodega.Onboarding.Controllers
{   
[DNNModuleAuthorization（AccessLevel=SecurityAccessLevel.View）]
[DnnHandleError]
公共类注册控制器：DnnBaseController
{  
//获得：注册
[ModuleAction（ControlKey=“Edit”，TitleKey=“AddItem”）]
公共行动结果索引（）
{  
var signups=OnboardingManager.Instance.GetOnboardings（ModuleContext.ModuleId）；
返回视图（注册）；
}  
}  
}  

我会使用像wireshark或fiddler这样的嗅探器，看看你的状态是否为200 OK。您可能会遇到错误。返回空响应，或未得到响应。若你们有一个应用程序可以工作，那个么将工作代码中的第一个请求和非工作代码进行比较。然后让你的c#看起来像是工作代码。所以当我浏览安装了结节的页面时，Fiddler给出了HTTP 200。然后HttpPost和请求很好，问题是解析响应。发布的代码是针对请求而不是响应的。您也可以发布您的dnn清单吗？我已经在更新的问题中添加了我的服务类逻辑和dnn清单的内容。谢谢你的帮助。
