8、其他扩展插件

用媒介信任的方式开发一个插件：https://shazwazza.com/post/Developing-a-plugin-framework-in-ASPNET-with-medium-trust.aspx

发布插件的时候需要注意：  直接编辑项目文件代码，发布的地址改成下面的格式，清理也要加。

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp2.1</TargetFramework>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
<OutputPath>..\..\Presentation\Nop.Web\Plugins\PLUGIN_OUTPUT_DIRECTORY</OutputPath>
<OutDir>$(OutputPath)</OutDir>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
<OutputPath>..\..\Presentation\Nop.Web\Plugins\PLUGIN_OUTPUT_DIRECTORY</OutputPath>
<OutDir>$(OutputPath)</OutDir>
</PropertyGroup>
<!-- This target execute after "Build" target -->
<Target Name="NopTarget" AfterTargets="Build">
<!-- Delete unnecessary libraries from plugins path -->
<MSBuild Projects="$(MSBuildProjectDirectory)\..\..\Build\ClearPluginAssemblies.proj" Properties="PluginPath=$(MSBuildProjectDirectory)\$(OutDir)" Targets="NopClear" />
</Target>
</Project>

Replace “PLUGIN_OUTPUT_DIRECTORY” in the code above with your real plugin output directory name.

下面开始讲下 挂件的创建。

首先创建Widgets项目，并拷贝原本的轮播图插件的文件夹.

添加core 跟services  web.framwork的项目引用

我们先保留components 、controllers、models、views、跟 三个文件，logo可以换一个自己的。 plugin.json 必须保留，里面信息先修改

修改 setting 设置

修改plugin

using System.Collections.Generic;
using Nop.Core;
using Nop.Core.Infrastructure;
using Nop.Core.Plugins;
using Nop.Services.Cms;
using Nop.Services.Configuration;
using Nop.Services.Localization;
using Nop.Services.Media;
using Nop.Web.Framework.Infrastructure;

namespace Nop.Plugin.Widgets.Modal
{
    /// <summary>
    /// PLugin
    /// </summary>
    public class ModalPlugin : BasePlugin, IWidgetPlugin
    {
        private readonly ILocalizationService _localizationService;
        private readonly IPictureService _pictureService;
        private readonly ISettingService _settingService;
        private readonly IWebHelper _webHelper;
        private readonly INopFileProvider _fileProvider;
        public ModalPlugin(ILocalizationService localizationService,
            IPictureService pictureService,
            ISettingService settingService,
            IWebHelper webHelper,
            INopFileProvider fileProvider)
        {
            this._localizationService = localizationService;
            this._pictureService = pictureService;
            this._settingService = settingService;
            this._webHelper = webHelper;
            this._fileProvider = fileProvider;
        }
        /// <summary>
        /// 获取挂件的区域位置标识（唯一的id）
        /// </summary>
        /// <returns>Widget zones</returns>
        public IList<string> GetWidgetZones()
        {
            return new List<string> { "home_page_modal"};//PublicWidgetZones.HomePageTop
        }

        /// <summary>
        /// 获取配置页面的url
        /// </summary>
        public override string GetConfigurationPageUrl()
        {
            return _webHelper.GetStoreLocation() + "Admin/WidgetsModal/Configure";
        }

        /// <summary>
        /// 返回要显示的部分视图名称
        /// </summary>
        /// <param name="widgetZone">Name of the widget zone</param>
        /// <returns>View component name</returns>
        public string GetWidgetViewComponentName(string widgetZone)
        {
            return "WidgetsModal";
        }

        /// <summary>
        /// Install plugin
        /// </summary>
        public override void Install()
        {
            //设置
            var settings = new ModalSettings
            {
            };
            _settingService.SaveSetting(settings);
            //设置本地资源缓存
            //_localizationService.AddOrUpdatePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture1", "Picture 1");        

            base.Install();
        }

        /// <summary>
        /// Uninstall plugin
        /// </summary>
        public override void Uninstall()
        {
            //settings
            _settingService.DeleteSetting<ModalSettings>();
            //locales
            //_localizationService.DeletePluginLocaleResource("Plugins.Widgets.NivoSlider.Picture1");          

            base.Uninstall();
        }
    }
}

然后修改对应的部分视图 WidgetsModalViewComponent

namespace Nop.Plugin.Widgets.Modal.Components
{
    [ViewComponent(Name = "WidgetsModal")]
    public class WidgetsModalViewComponent : NopViewComponent
    {
        private readonly IStoreContext _storeContext;
        private readonly IStaticCacheManager _cacheManager;
        private readonly ISettingService _settingService;
        private readonly IPictureService _pictureService;

        public WidgetsModalViewComponent(IStoreContext storeContext,
            IStaticCacheManager cacheManager,
            ISettingService settingService,
            IPictureService pictureService)
        {
            this._storeContext = storeContext;
            this._cacheManager = cacheManager;
            this._settingService = settingService;
            this._pictureService = pictureService;
        }

        public IViewComponentResult Invoke(string widgetZone, object additionalData)
        {
            var nivoSliderSettings = _settingService.LoadSetting<ModalSettings>(_storeContext.CurrentStore.Id);

            var model = new PublicInfoModel
            {
                Name = "嘿嘿哈哈"
            };     

            return View("~/Plugins/Widgets.Modal/Views/PublicInfo.cshtml", model);
        }

        protected string GetPictureUrl(int pictureId)
        {
            //var cacheKey = string.Format(ModelCacheEventConsumer.PICTURE_URL_MODEL_KEY, pictureId);
            //return _cacheManager.Get(cacheKey, () =>
            //{
            //    //little hack here. nulls aren't cacheable so set it to ""
            //    var url = _pictureService.GetPictureUrl(pictureId, showDefaultPicture: false) ?? "";
            //    return url;
            //});
            return "";
        }
    }
}

　　

然后呢 修改下配置文件模型；ConfigurationModel

namespace Nop.Plugin.Widgets.Modal.Models
{
    public class ConfigurationModel : BaseNopModel
    {
        public int ActiveStoreScopeConfiguration { get; set; }

    }
}

修改views里面的配置前端

@model ZXS.Plugin.Widgets.Modal.Models.ConfigurationModel
@{
    Layout = "_ConfigurePlugin";
}

@await Component.InvokeAsync("StoreScopeConfiguration")
<form asp-controller="WidgetsNivoSlider" asp-action="Configure" method="post">
    <div class="panel-group">
       这里是配置页面

        <div class="panel panel-default">
            <div class="panel-body">
                <div class="form-group">
                    <div class="col-md-9 col-md-offset-3">
                        <input type="submit" name="save" class="btn bg-blue" value="@T("Admin.Common.Save")" />
                    </div>
                </div>
            </div>
        </div>
    </div>
</form>

下面是modal的前端

@model ZXS.Plugin.Widgets.Modal.Models.PublicInfoModel
@{
    Layout = "";

    Html.AddScriptParts(ResourceLocation.Footer, "~/Plugins/Widgets.Modal/Content/layui.all.js");
    Html.AddCssFileParts("~/Plugins/Widgets.Modal/Content/css/layui.css");
}

<div class="slider-wrapper theme-custom">
    <div id="nivo-slider" class="nivoSlider">
      <button onclick="loading();">点击弹窗</button>
    </div>
</div>
<script asp-location="Footer">
    //loading层
    function loading() {
        var index = layer.load(, {
            shade: [0.1, '#fff'] //0.1透明度的白色背景
        });
    }
</script>

修改控制器：WidgetsModalController

using System.Linq;
using Microsoft.AspNetCore.Mvc;
using Nop.Core;
using Nop.Core.Caching;
using ZXS.Plugin.Widgets.Modal.Models;
using Nop.Services.Configuration;
using Nop.Services.Localization;
using Nop.Services.Media;
using Nop.Services.Security;
using Nop.Web.Framework;
using Nop.Web.Framework.Controllers;

namespace ZXS.Plugin.Widgets.Modal.Controllers
{
    [Area(AreaNames.Admin)]
    public class WidgetsModalController : BasePluginController
    {
        private readonly IStoreContext _storeContext;
        private readonly IPermissionService _permissionService;
        private readonly IPictureService _pictureService;
        private readonly ISettingService _settingService;
        private readonly ILocalizationService _localizationService;

        public WidgetsModalController(IStoreContext storeContext,
            IPermissionService permissionService,
            IPictureService pictureService,
            ISettingService settingService,
            ICacheManager cacheManager,
            ILocalizationService localizationService)
        {
            this._storeContext = storeContext;
            this._permissionService = permissionService;
            this._pictureService = pictureService;
            this._settingService = settingService;
            this._localizationService = localizationService;
        }

        public IActionResult Configure()
        {
            //权限验证
            //if (!_permissionService.Authorize(StandardPermissionProvider.ManageWidgets))
            //    return AccessDeniedView();

            //load settings for a chosen store scope
            var storeScope = _storeContext.ActiveStoreScopeConfiguration;
            var nivoSliderSettings = _settingService.LoadSetting<ModalSettings>(storeScope);
            var model = new ConfigurationModel
            {
                ActiveStoreScopeConfiguration = storeScope
            };

            if (storeScope > )
            {

            }

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

        [HttpPost]
        public IActionResult Configure(ConfigurationModel model)
        {
            //now clear settings cache
            _settingService.ClearCache();

            SuccessNotification(_localizationService.GetResource("Admin.Plugins.Saved"));
            return Configure();
        }
    }
}
 

右键项目生成，看看是不是到web项目的插件文件夹了

记得在商城启用控件，然后在home 首页调用它。效果如下

第一次写比较乱，有需要源码的留言。我整理下会放出来
