NopCommerce插件内建自定义插件

问题描述 投票：0回答：1

我正在使用Nopcommerce 4.2，并试图创建一个自定义插件。

在运行时，我得到了错误。

System.Exception: 'A plugin with 'DiscountRequirement.MustBeAssignedToCustomerRole' system name is already defined

当我进入Nop.WebPlugins时，我可以看到所有已经建立的插件--包括我的。当我查看我的自定义插件时，我可以看到一个名为Plugins的文件夹，这个文件夹包含了所有其他已经建立的插件。

我已经看了我的csproj，并与nop默认插件进行了比较，不能解决为什么我的再次建立所有的插件。

要清楚的是，正在创建的结构是:

Nop.Web

  • 插件

    --折扣规则.客户角色(CustomerRoles)

    --ExchangeRate.EcbExchange

    --...其他插件....

    --我的.插件

    ---应用数据

    -----区域

    ---插件

    ------------------------------------------------------------------------------------------------------折扣规则.客户角色

    ----ExchangeRate.EcbExchange

    --------------------------------------------------------------------------------其他插件...

请清空你的垃圾箱，并删除这个""下的所有插件。Nop.Web -> 插件。"文件夹一次。这对我来说是有效的，谢谢

有几个地方是有错误的。不检查无法给出答案，如plugin.json，dependencyregister.cs，plugin.cs等。

但是当你熟悉了之后，你就可以找到自己的方法来加快你的开发速度了。

小贴士：如果你的插件还存在任何问题，这是最简单的方法。

  1. 只要把小原插件复制一份，如'Nop.Plugin.Payments.Qualpay,Square,SendinBlue'，然后重命名，然后编辑.proj文件设置输出文件夹。
  2. 删除除了'DependencyRegistrar.cs,RouteProvider.cs,plugin.json,StartUpPlugin.cs'以外的所有不必要的类、文件和文件夹。
  3. 改变其余文件的命名空间，并删除不必要的代码。
  4. 在 插件.json "SupportedVersions": [ "4.20"] 是一个必须的值
  5. 构建并清除所有错误。
  6. 它应该出现在'配置 > 本地配置'

小贴士：这是我的项目建设最佳实践，当我收到参考资料错误的时候

  1. 清洗溶液
  2. 进入 ~APIPresentationNop.WebPlugins 文件夹，删除所有的构建文件夹。
  3. 右键点击'图书馆'文件夹并建立它。
  4. 右键单击'演示文稿'文件夹并建立它。
  5. 右键单击'插件'文件夹并建立它。
  6. 祝你好运...!

你可以参考下面的模板

插件.json ("SupportedVersions": [ "4.20"] 是一个必须的值)，否则插件服务将不会选择你的插件。

{
  "Group": "Plugin group name",
  "FriendlyName": "Elastic Search",
  "SystemName": "Custom.Plugin.ElasticSearch",
  "Version": "1.56",
  "SupportedVersions": [ "4.20" ],
  "Author": "Isanka Thalagala",
  "DisplayOrder": 27,
  "FileName": "Custom.Plugin.ElasticSearch.dll",
  "Description": "This plugin provice ilastic search"
}

DependencyRegistrar.cs class

public class DependencyRegistrar : IDependencyRegistrar
{
   /// <summary>
   /// Register services and interfaces
   /// </summary>
   /// <param name="builder">Container builder</param>
   /// <param name="typeFinder">Type finder</param>
   /// <param name="config">Config</param>
   public virtual void Register(ContainerBuilder builder, ITypeFinder typeFinder, NopConfig config)
   {
      //register service manager
      builder.RegisterType<SearchFilterService>().As<ISearchFilterService>().InstancePerLifetimeScope();
      builder.RegisterType<ElasticSearchService>().As<IElasticSearchService>().InstancePerLifetimeScope();          
   }

   /// <summary>
   /// Gets order of this dependency registrar implementation
   /// </summary>
   public int Order => 1;
}

ElasticSearchPlugin.cs

public class ElasticSearchPlugin : BasePlugin
    {
        #region Ctor
        public ElasticSearchPlugin()
        {
        }

        #endregion

        #region Methods
        /// <summary>
        /// Install the plugin
        /// </summary>
        public override void Install()
        {
            base.Install();
        }

        /// <summary>
        /// Uninstall the plugin
        /// </summary>
        public override void Uninstall()
        {
            base.Uninstall();
        }

        #endregion

        /// <summary>
        /// Gets a value indicating whether to hide this plugin on the widget list page in the admin area
        /// </summary>
        public bool HideInWidgetList => true;
    }
