nopCommerce 3.9 大波浪系列之开发支持多店的插件

2022-08-14 09:25:17

一.基础介绍

nop支持多店及多语言，本篇结合NivoSlider插件介绍下如何开发支持多商城的小部件。

主要接口如下：

ISettingService 接口：设置接口，可实现多店配置。

ILocalizationService 接口：本地化资源接口，配合语言，实现多语言的显示。

二.插件安装、卸载

我们在上一篇介绍了小部件如何使用（点击这里），这里介绍下如何安装、卸载插件。

【后台管理】【插件管理】【本地插件】可以对插件进行安装、卸载

Nop.Admin.Controllers.PluginController控制器用于插件的管理。Install负责安装插件、Uninstall负责卸载插件。

所有插件都继承IPlugin接口，Install()，Uninstall()分别用于安装及卸载。

 namespace Nop.Core.Plugins

 {

     /// <summary>

     /// Interface denoting plug-in attributes that are displayed throughout

     /// the editing interface.

     /// </summary>

     public interface IPlugin

     {

         /// <summary>

         /// Gets or sets the plugin descriptor

         /// </summary>

         PluginDescriptor PluginDescriptor { get; set; }

         /// <summary>

         /// Install plugin

         /// </summary>

         void Install();

         /// <summary>

         /// Uninstall plugin

         /// </summary>

         void Uninstall();

     }

 }

BasePlugin抽象类继承了IPlugin接口，并实现了 Install()，Uninstall()方法，当安装时在"~/App_Data/InstalledPlugins.txt"文件中写入插件的SystemName，卸载时则在文件中删除。

 namespace Nop.Core.Plugins

 {

     /// <summary>

     /// Base plugin

     /// </summary>

     public abstract class BasePlugin : IPlugin

     {

         /// <summary>

         /// Gets or sets the plugin descriptor

         /// </summary>

         public virtual PluginDescriptor PluginDescriptor { get; set; }

         /// <summary>

         /// Install plugin

         /// </summary>

         public virtual void Install()

         {

             PluginManager.MarkPluginAsInstalled(this.PluginDescriptor.SystemName);

         }

         /// <summary>

         /// Uninstall plugin

         /// </summary>

         public virtual void Uninstall()

         {

             PluginManager.MarkPluginAsUninstalled(this.PluginDescriptor.SystemName);

         }

     }

 }

         {

             //pictures

             var sampleImagesPath = CommonHelper.MapPath("~/Plugins/Widgets.NivoSlider/Content/nivoslider/sample-images/");

             //settings

             var settings = new NivoSliderSettings

             {

                 Picture1Id = _pictureService.InsertPicture(File.ReadAllBytes(sampleImagesPath + "banner1.jpg"), MimeTypes.ImagePJpeg, "banner_1").Id,

                 //Link3 = _webHelper.GetStoreLocation(false),

             };

             _settingService.SaveSetting(settings);

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture1", "Picture 1");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture2", "Picture 2");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture3", "Picture 3");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture4", "Picture 4");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture5", "Picture 5");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture", "Picture");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture.Hint", "Upload picture.");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Text", "Comment");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Text.Hint", "Enter comment for picture. Leave empty if you don't want to display any text.");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Link", "URL");

             this.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Link.Hint", "Enter URL. Leave empty if you don't want this picture to be clickable.");

             base.Install();

         }

         /// <summary>

         /// Uninstall plugin

         /// </summary>

         public override void Uninstall()

         {

             //settings

             _settingService.DeleteSetting<NivoSliderSettings>();

             //locales

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture1");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture2");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture3");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture4");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture5");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture.Hint");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Text");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Text.Hint");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Link");

             this.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Link.Hint");

             base.Uninstall();

         }

     }

 }

Nop.Plugin.Widgets.NivoSlider

在上边源代码中我们看到安装时调用Install()方法进行了如下操作

1.定义NivoSliderSettings类，该类继承ISettings，用于保存幻灯片的配置。将初始化的配置保存到数据库Setting表中。

2.this.AddOrUpdatePluginLocaleResource方法添加本地资源，主要用于配置资源在多语言支持。

3.base.Install() 进行插件安装。

卸载插件时调用Uninstall()方法对配置进行删除，对本地资源进行删除同时卸载插件。

以上就是在插件安装、卸载时调用的方法介绍，在二次开发时可在相关时间点进行插件的配置。

三.插件配置路由

不同插件有属于自己的配置项，例如支付宝插件和微信支付插件同是支付插件但是配置却不一样。为了实现不同配置引入了配置路由。小部件IWidgetPlugin接口GetConfigurationRoute方法用于返回配置接口的路由信息。我们看下NivoSlider插件

    /// <summary>

         /// Gets a route for provider configuration

         /// </summary>

         /// <param name="actionName">Action name</param>

         /// <param name="controllerName">Controller name</param>

         /// <param name="routeValues">Route values</param>

         public void GetConfigurationRoute(out string actionName, out string controllerName, out RouteValueDictionary routeValues)

         {

             actionName = "Configure";

             controllerName = "WidgetsNivoSlider";

             routeValues = new RouteValueDictionary { { "Namespaces", "Nop.Plugin.Widgets.NivoSlider.Controllers" }, { "area", null } };

         }

当点击配置时路由到WidgetsNivoSlider控制器Configure()方法，显示插件配置页面

四.多店配置实现

如果配置了两个以上的商城就会出现上边的多店设置。可针对不同商店进行不同的配置。

 [AdminAuthorize]

         [ChildActionOnly]

         public ActionResult Configure()

         {

             //加载可用商店的范围

             var storeScope = this.GetActiveStoreScopeConfiguration(_storeService, _workContext);

             var nivoSliderSettings = _settingService.LoadSetting<NivoSliderSettings>(storeScope);//加载可用商店的配置

             var model = new ConfigurationModel();

             model.Picture1Id = nivoSliderSettings.Picture1Id;

             model.Text1 = nivoSliderSettings.Text1;

             model.Link1 = nivoSliderSettings.Link1;

             model.Picture2Id = nivoSliderSettings.Picture2Id;

             model.Text2 = nivoSliderSettings.Text2;

             model.Link2 = nivoSliderSettings.Link2;

             model.Picture3Id = nivoSliderSettings.Picture3Id;

             model.Text3 = nivoSliderSettings.Text3;

             model.Link3 = nivoSliderSettings.Link3;

             model.Picture4Id = nivoSliderSettings.Picture4Id;

             model.Text4 = nivoSliderSettings.Text4;

             model.Link4 = nivoSliderSettings.Link4;

             model.Picture5Id = nivoSliderSettings.Picture5Id;

             model.Text5 = nivoSliderSettings.Text5;

             model.Link5 = nivoSliderSettings.Link5;

             model.ActiveStoreScopeConfiguration = storeScope;

             if (storeScope > 0)

             {

                 model.Picture1Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture1Id, storeScope);

                 model.Text1_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text1, storeScope);

                 model.Link1_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link1, storeScope);

                 model.Picture2Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture2Id, storeScope);

                 model.Text2_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text2, storeScope);

                 model.Link2_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link2, storeScope);

                 model.Picture3Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture3Id, storeScope);

                 model.Text3_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text3, storeScope);

                 model.Link3_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link3, storeScope);

                 model.Picture4Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture4Id, storeScope);

                 model.Text4_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text4, storeScope);

                 model.Link4_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link4, storeScope);

                 model.Picture5Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture5Id, storeScope);

                 model.Text5_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text5, storeScope);

                 model.Link5_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link5, storeScope);

             }

             return View("~/Plugins/Widgets.NivoSlider/Views/Configure.cshtml", model);

         }

配置源码

查看源码我们会发现这两句是控制多店配置的

  //加载可用商店的范围

  var storeScope = this.GetActiveStoreScopeConfiguration(_storeService, _workContext);

  var nivoSliderSettings = _settingService.LoadSetting<NivoSliderSettings>(storeScope);//加载可用商店的配置

首先加载当前配置的商店。获取到 storeScope后加载该商店NivoSliderSetting配置项的设置。

这样当选择不同的商城就可以获取到选择商城中配置的值了。

我们再来看下Configure.cshtml视图

@Html.Action("StoreScopeConfiguration", "Setting", new { area = "Admin" })

该路由用于生成nop多店设置模块，选择不同商城会调用Setting控制器，ChangeStoreScopeConfiguration方法，该方法会将用户选择的商城id 保存在GenericaAttribute表中如下图。

SystemCustomerAttributeNames.AdminAreaStoreScopeConfiguration变量对应的就是Key值，Velue保存为商城的Id。

当页面选择不同的商城时，经过上边方法的处理，再调用var storeScope = this.GetActiveStoreScopeConfiguration(_storeService, _workContext); 方法就可以获取到指定的商城了。

当指定商城时我们会发现配置项每一项都多出一个单选框，选择则可针对该商城的该配置经进行设置，如果不选择则使用默认项。

在视图中如何生成这个单选项呢？看下源码

@Html.OverrideStoreCheckboxFor(model => model.Picture2Id_OverrideForStore, model => model.Picture2Id, Model.ActiveStoreScopeConfiguration)

使用该Html扩展来实现商城配置的定制。OverrideStoreCheckboxFor扩展是Nop.Web.Framework.HtmlExtensions 类中的扩展。

model.Picture2Id_OverrideForStore为True时使用自定义商城配置，model.Picture2Id为配置属性，model.ActiveStoreScopeConfiguration为当前商城id。

可以看出支持多店配置的model比普通model多出ActiveStoreScopeConfiguration属性用于保存商城id，同时每个属性多一个_OverrideForStore的bool方法用于判断是否覆盖店铺默认值。

             nivoSliderSettings.Link5 = model.Link5;

             /* We do not clear cache after each setting update.

              * This behavior can increase performance because cached settings will not be cleared

              * and loaded from database after each update */

             _settingService.ClearCache();

             //get current picture identifiers

             var currentPictureIds = new[]

             {

             //delete an old picture (if deleted or updated)

             foreach (var pictureId in previousPictureIds.Except(currentPictureIds))

             {

                 var previousPicture = _pictureService.GetPictureById(pictureId);

                 if (previousPicture != null)

                     _pictureService.DeletePicture(previousPicture);

             }

             SuccessNotification(_localizationService.GetResource("Admin.Plugins.Saved"));

             return Configure();

         }

提交配置代码

啰嗦了这么多，其实就是一样，在Setting表中插入一条绑定商城Id的记录如下图：

Name就是对应的配置字段，Value为值，StoreId为商城id。

五.总结

1.IPlugin接口，Install()，Uninstall()分别用于安装及卸载

2.IWidgetPlugin接口,GetConfigurationRoute方法用于返回配置接口的路由信息

3.视图中@Html.Action("StoreScopeConfiguration", "Setting", new { area = "Admin" })用于多店配置

4.多店属性设置使用@Html.OverrideStoreCheckboxFor扩展。

5.多店设置保存使用ISettingService接口SaveSettingOverridablePerStore方法。
