nopCommerce 3.9 大波浪系列之开发支持多店的…

2018-06-22 06:13:53来源：未知阅读 ()

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。

  1 namespace Nop.Core.Plugins
  2 {
  3     /// <summary>
  4     /// Interface denoting plug-in attributes that are displayed throughout 
  5     /// the editing interface.
  6     /// </summary>
  7     public interface IPlugin
  8     {
  9         /// <summary>
 10         /// Gets or sets the plugin descriptor
 11         /// </summary>
 12         PluginDescriptor PluginDescriptor { get; set; }
 13 
 14         /// <summary>
 15         /// Install plugin
 16         /// </summary>
 17         void Install();
 18 
 19         /// <summary>
 20         /// Uninstall plugin
 21         /// </summary>
 22         void Uninstall();
 23     }
 24 }
 25

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。

  1 namespace Nop.Core.Plugins
  2 {
  3     /// <summary>
  4     /// Base plugin
  5     /// </summary>
  6     public abstract class BasePlugin : IPlugin
  7     {
  8         /// <summary>
  9         /// Gets or sets the plugin descriptor
 10         /// </summary>
 11         public virtual PluginDescriptor PluginDescriptor { get; set; }
 12 
 13         /// <summary>
 14         /// Install plugin
 15         /// </summary>
 16         public virtual void Install()
 17         {
 18             PluginManager.MarkPluginAsInstalled(this.PluginDescriptor.SystemName);
 19         }
 20 
 21         /// <summary>
 22         /// Uninstall plugin
 23         /// </summary>
 24         public virtual void Uninstall()
 25         {
 26             PluginManager.MarkPluginAsUninstalled(this.PluginDescriptor.SystemName);
 27         }
 28 
 29     }
 30 }

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

  1    /// <summary>
  2         /// Gets a route for provider configuration
  3         /// </summary>
  4         /// <param name="actionName">Action name</param>
  5         /// <param name="controllerName">Controller name</param>
  6         /// <param name="routeValues">Route values</param>
  7         public void GetConfigurationRoute(out string actionName, out string controllerName, out RouteValueDictionary routeValues)
  8         {
  9             actionName = "Configure";
 10             controllerName = "WidgetsNivoSlider";
 11             routeValues = new RouteValueDictionary { { "Namespaces", "Nop.Plugin.Widgets.NivoSlider.Controllers" }, { "area", null } };
 12         }

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

$C08]NI@_X%HO_J$H{VC$B53$

四.多店配置实现

MYRGDJGMO~MSD@G{MC6$YEO

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。

  1 [AdminAuthorize]
  2         [ChildActionOnly]
  3         public ActionResult Configure()
  4         {
  5             //加载可用商店的范围
  6             var storeScope = this.GetActiveStoreScopeConfiguration(_storeService, _workContext);
  7             var nivoSliderSettings = _settingService.LoadSetting<NivoSliderSettings>(storeScope);//加载可用商店的配置
  8             var model = new ConfigurationModel();
  9             model.Picture1Id = nivoSliderSettings.Picture1Id;
 10             model.Text1 = nivoSliderSettings.Text1;
 11             model.Link1 = nivoSliderSettings.Link1;
 12             model.Picture2Id = nivoSliderSettings.Picture2Id;
 13             model.Text2 = nivoSliderSettings.Text2;
 14             model.Link2 = nivoSliderSettings.Link2;
 15             model.Picture3Id = nivoSliderSettings.Picture3Id;
 16             model.Text3 = nivoSliderSettings.Text3;
 17             model.Link3 = nivoSliderSettings.Link3;
 18             model.Picture4Id = nivoSliderSettings.Picture4Id;
 19             model.Text4 = nivoSliderSettings.Text4;
 20             model.Link4 = nivoSliderSettings.Link4;
 21             model.Picture5Id = nivoSliderSettings.Picture5Id;
 22             model.Text5 = nivoSliderSettings.Text5;
 23             model.Link5 = nivoSliderSettings.Link5;
 24             model.ActiveStoreScopeConfiguration = storeScope;
 25             if (storeScope > 0)
 26             {
 27                 model.Picture1Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture1Id, storeScope);
 28                 model.Text1_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text1, storeScope);
 29                 model.Link1_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link1, storeScope);
 30                 model.Picture2Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture2Id, storeScope);
 31                 model.Text2_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text2, storeScope);
 32                 model.Link2_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link2, storeScope);
 33                 model.Picture3Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture3Id, storeScope);
 34                 model.Text3_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text3, storeScope);
 35                 model.Link3_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link3, storeScope);
 36                 model.Picture4Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture4Id, storeScope);
 37                 model.Text4_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text4, storeScope);
 38                 model.Link4_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link4, storeScope);
 39                 model.Picture5Id_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Picture5Id, storeScope);
 40                 model.Text5_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Text5, storeScope);
 41                 model.Link5_OverrideForStore = _settingService.SettingExists(nivoSliderSettings, x => x.Link5, storeScope);
 42             }
 43 
 44             return View("~/Plugins/Widgets.NivoSlider/Views/Configure.cshtml", model);
 45         }

配置源码

查看源码我们会发现这两句是控制多店配置的

  1  //加载可用商店的范围
  2  var storeScope = this.GetActiveStoreScopeConfiguration(_storeService, _workContext);
  3  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。

(IDL)4E2P@]U8JOP_628@)I

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。

 74             }
 75 
 76             SuccessNotification(_localizationService.GetResource("Admin.Plugins.Saved"));
 77             return Configure();
 78         }

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：

AA$QHZFM~[ZN9`IME5FS2%7

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。
