如何解决 DNN 自定义模块不渲染的问题？

Question

我正在使用 DNN 9.3.2 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);

    }
}

上面引用的服务类定义如下：

public class ProPayService
{
    private static HttpClient _httpClient = new HttpClient();
    //private readonly string _baseUrl = "https://xmltestapi.propay.com/ProPayAPI";
    Uri _baseUrl = new Uri("https://xmltestapi/propay.com/ProPayAPI");

    public ProPayResponse MerchantSignupForProPayAsync()
    {
        SignupRequest signupRequest = new SignupRequest();
            SignupResponse signupResponse = new SignupResponse();
            HttpContent content = new StringContent(signupRequest.ToString());
            CancellationToken cancellationToken = new CancellationToken();
            var credentials = GetCredentials();
            var responseBody = _httpClient.PutAsync(_baseUrl, content, cancellationToken).Result;
        try
        {
            BuildMerchantTestData();

            Console.WriteLine(responseBody);
            Console.WriteLine(content);
            if (WebRequest.Create(_baseUrl) is HttpWebRequest httpRequest)
            {
                httpRequest.Method = "PUT";
                httpRequest.Headers.Add("accept", "applicaiton/json");
                httpRequest.Headers.Add("Authorization", credentials);
            }

            //var httpRequest = new HttpRequestMessage(HttpMethod.Put, _baseUrl);
            //httpRequest.Headers.Add("Authorization", credentials);

            Console.WriteLine(signupResponse.Status);
        }
        catch (HttpRequestException e)
        {
            Console.WriteLine("\nException caught");
            Console.WriteLine("Message: {0} ", e.Message);
        }

        return JsonConvert.DeserializeObject<ProPayResponse>(responseBody.Content.ReadAsStringAsync().Result);
    }
    private SignupRequest BuildMerchantTestData()
    {
        int moduleId = 0;
        int OnboardingId = 0;
        var result = OnboardingManager.Instance.GetOnboarding(OnboardingId, moduleId);
        var onboardingList = new List<Models.Onboarding>();
        var ownerList = new List<OwnerList>();


        SignupRequest signupRequest = new SignupRequest();
        if (result != null)
        {
            Debug.Assert(result != null, nameof(OnboardingList) + " != null");
            Console.WriteLine("{0} {1}", result.Email, result.UserId);
            List<Owner> owner1 = new List<Owner>
            {

我是否应该对上述控制器进行更改以确保模块正确呈现？ 或者我应该检查其他项目以进一步诊断问题吗？

更新：根据评论对 DNN 清单进行更改后，我现在无法将模块添加到页面并在管理日志中收到以下内容：

UPDATE2我上周晚些时候升级到9.4 DNN并把收到的通知注释掉所有代码在我看来，只是呈现一个标签。 这有效！！ 因此，我的视图语法如下：

@inherits 
DotNetNuke.Web.Mvc.Framework.DnnWebViewPage
<DotNetNuke.Collections.PagedList<SocialBodega.Onboarding.
Models.Onboarding>>

@using System.Linq
@using System.Text.RegularExpressions
@using DotNetNuke.Collections
@using DotNetNuke.Entities.Urls
@using DotNetNuke.Web.Mvc.Helpers

<div id="Onboarding-@Dnn.ModuleContext.ModuleId">
@if (Model == null|| !Model.Any())

    {
    <p>@Dnn.LocalizeString("NoSignups")</p>
}
else
{
    <ul>
        @foreach (var onboarding in Model)
        {
            <li>
                <h3>@onboarding.FirstName</h3>
                <div>@onboarding.OnboardingId</div>
                @{
                    if (Dnn.ModuleContext.IsEditable)
                    {
                        <div>
                            <a href="@Url.Action("Edit","Signup", new{ctl = "Edit", onboardingId = onboarding.OnboardingId, })">@Dnn.LocalizeString("EditItem")</a>
                        </div>
                    }
                }
            </li>
        }
    </ul>
}
</div>
@*@Html.Label("Testing 123");*@

当我构建解决方案时，它成功了，但我在 Visual Studio 2019 中收到了 16 条错误消息，其效果如下：

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   

我已将上述程序集添加到模块的 Views 文件夹中的 web.config 以及 C:\\websites.dnndev.me 的主 DNN web.config 中，使用以下命令：

    <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预期呈现？

Answer 1

首先，确保您的模块针对 DNN 实例所针对的正确版本的 .NET Framework 进行编译。 您可以在 web.config 文件中查找与此类似的一行：

<compilation debug="false" strict="false" targetFramework="4.5">  

在 DNN 的最新版本中，您需要确保明确告诉 DNN 您的控制器要响应的权限。 请注意以下示例中的DnnModuleAuthorize类装饰。

using System;  
using System.Web.Mvc;  
using DotNetNuke.Entities.Modules;  
using DotNetNuke.Security;  
using DotNetNuke.Services.Exceptions;  
using DotNetNuke.Web.Mvc.Framework.ActionFilters;  

namespace SocialBodega.Onboarding.Controllers   
{   
    [DnnModuleAuthorize(AccessLevel = SecurityAccessLevel.View)]  
    [DnnHandleError]  
    public class SignupController : DnnBaseController  
    {  
        // GET: Signup  
        [ModuleAction(ControlKey = "Edit", TitleKey = "AddItem")]  
        public ActionResult Index()  
        {  
            var signups = OnboardingManager.Instance.GetOnboardings(ModuleContext.ModuleId);  
            return View(signups);  
        }  
    }  
}
