前言

童鞋們，大家好

我是專註.NET開發者社區建設的實踐者Rector。

首先，為自己間隔了兩個星期五再更新本系列文章找個不充分的理由：Rector最近工作，家庭的各種事務所致，希望大家諒解。

本文知識要點

回到本文的主題，還是關於系列文章：《一步一步創建ASP.NET MVC5程式Repository+Autofac+Automapper+SqlSugar》，本文將為大家分享的主要內容有：

響應式網站首頁的佈局與製作
文章列表的展示
文章詳情頁面

前端佈局與製作

響應式網站首頁的佈局與製作

在以本文之前的系列文章的頁面中，我們的網站首頁以及文章列表頁面都沒有應用樣式，本文將給大家分享首頁的製作，其中包含的內容有：

頭部導航
文章列表
Bootstrap響應式佈局

最終的首頁效果圖如下：

create-aspnet-mvc-5-web-application-repository-autofac-automapper-sqlsugar-step-by-step-09-01.png

CSS樣式

首先，在項目[TsBlog.Frontend]中創建資源文件夾命名為：resources，在其中創建一個css樣式文件夾，並新建一個樣式文件，命名為：site.css，此時的目錄結構如下：

create-aspnet-mvc-5-web-application-repository-autofac-automapper-sqlsugar-step-by-step-09-02.png

樣式代碼如下：

site.css

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,

    .article-content ul li { padding-left: 15px; list-style: inside; }
    .article-content ul, .article-content ol { margin-left: 3em; padding-left: 0; }
        .article-content ul li, .article-content ol li { margin: .3em 0; }

以上的樣式表是本文中所用到的，你只需要複製即可。

頭部導航

打開視圖文件[...TsBlog\src\Presentation\TsBlog.Frontend\Views\Home\Index.cshtml]，首先製作頭部導航條，其中導航條的HTML代碼如下：

<nav class="navbar navbar-default navbar-static-top ts-navbar">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">

                </ul>
            </div><!--/.nav-collapse -->
        </div>
    </nav>

正文HTML

其中正文的第一部分為一個BANNER，在這個區域中，可以放置一些重要的關於站點的描述信息，也可以放滾動播放的廣告圖片等，按自己的需要處理就可以了。

第二部分則是一個文章列表區域，其中列出了網站最近發佈的20條文章列表，正文的HTML代碼如下：

<div class="container">
        <div class="jumbotron">
            <h1>小伙伴，你好</h1>
            <p>歡迎來到 Rector 的ASP.NET MVC 5 系列文章教程。在這裡，Rector將和你一起一步一步創建一個集成Repository+Autofac+Automapper+SqlSugar的WEB應用程式。</p>
            <p>你準備好了嗎？</p>
            <p>......</p>
            <p>讓我們開始ASP.NET MVC 5 應用程式的探索之旅吧!!!</p>
        </div>
        <strong class="post-title">文章列表(@(Model.Count())篇)</strong>
        <ul class="list-unstyled post-item-box">
            @foreach (var p in Model)
            {
                <li>
                    <h2><a href="~/post/details/@p.Id">@p.Title</a></h2>
                    <p class="post-item-summary">@p.Summary ... <a href="~/post/details/@p.Id">閱讀全文</a></p>
                </li>
            }
        </ul>
    </div>

頁腳

頁面最後為頁腳部分，包含比較簡單的版權等信息，HTML代碼如下：

<footer class="footer-box">
        <div class="container">
            版權所有 &copy; @(DateTime.Now.Year)
        </div>
    </footer>

首頁完整的HTML代碼如下：

Index.cshtml

    Layout = null;
}

後端介面與實現

在完成了前端頁面的佈局與製作之後，我們需要後端程式提供介面和服務，來供前端頁面調用，如首頁視圖中的視圖模型：

@model IEnumerable<TsBlog.ViewModel.Post.PostViewModel>

文章倉儲介面和實現

打開文件[IPostRepository.cs]，在其中新增介面方法： FindHomePagePosts ，代碼如下：

using System.Collections.Generic;
using TsBlog.Domain.Entities;

namespace TsBlog.Repositories
{
    public interface IPostRepository : IRepository<Post>
    {
        /// <summary>
        /// 查詢首頁文章列表
        /// </summary>
        /// <param name="limit">要查詢的記錄數</param>
        /// <returns></returns>
        IEnumerable<Post> FindHomePagePosts(int limit = 20);
    }
}

打開文件[PostRepository.cs]，實現對應的介面方法：FindHomePagePosts，代碼如下：

using SqlSugar;
using System.Collections.Generic;
using TsBlog.Domain.Entities;

namespace TsBlog.Repositories
{
    /// <summary>
    /// POST表的資料庫操作類
    /// </summary>
    public class PostRepository : GenericRepository<Post>, IPostRepository
    {
        #region Implementation of IPostRepository

        /// <summary>
        /// 查詢首頁文章列表
        /// </summary>
        /// <param name="limit">要查詢的記錄數</param>
        /// <returns></returns>
        public IEnumerable<Post> FindHomePagePosts(int limit = 20)
        {
            using (var db = DbFactory.GetSqlSugarClient())
            {
                var list = db.Queryable<Post>().OrderBy(x => x.Id, OrderByType.Desc).Take(limit).ToList();
                return list;
            }
        }
    }
    #endregion
}

文章服務介面和實現

打開文件[IPostService.cs]，在其中新增介面方法： FindHomePagePosts ，代碼如下：

using System.Collections.Generic;
using TsBlog.Domain.Entities;

namespace TsBlog.Services
{
    public interface IPostService : IService<Post>
    {
        /// <summary>
        /// 查詢首頁文章列表
        /// </summary>
        /// <param name="limit">要查詢的記錄數</param>
        /// <returns></returns>
        IEnumerable<Post> FindHomePagePosts(int limit = 20);
    }
}

打開文件[PostService.cs]，實現對應的介面方法：FindHomePagePosts，代碼如下：

using System.Collections.Generic;
using TsBlog.Domain.Entities;
using TsBlog.Repositories;

namespace TsBlog.Services
{
    public class PostService : GenericService<Post>, IPostService
    {
        private readonly IPostRepository _repository;
        public PostService(IPostRepository repository) : base(repository)
        {
            _repository = repository;
        }


        #region Implementation of IPostService

        /// <summary>
        /// 查詢首頁文章列表
        /// </summary>
        /// <param name="limit">要查詢的記錄數</param>
        /// <returns></returns>
        public IEnumerable<Post> FindHomePagePosts(int limit = 20)
        {
            return _repository.FindHomePagePosts(limit);
        }

        #endregion
    }
}

附加修改：重構了一下倉儲介面中的 FindListByClause 方法，將orderBy參數設置為可空參數，具體實現如下：

/// <summary>
/// 根據條件查詢數據
/// </summary>
/// <param name="predicate">條件表達式樹</param>
/// <param name="orderBy">排序</param>
/// <returns>泛型實體集合</returns>
IEnumerable<T> FindListByClause(Expression<Func<T, bool>> predicate, string orderBy = "");

對應的修改泛型倉儲中的對應實現：

/// <summary>
/// 根據條件查詢數據
/// </summary>
/// <param name="predicate">條件表達式樹</param>
/// <param name="orderBy">排序</param>
/// <returns>泛型實體集合</returns>
public IEnumerable<T> FindListByClause(Expression<Func<T, bool>> predicate, string orderBy = "")
{
    using (var db = DbFactory.GetSqlSugarClient())
    {
        var query = db.Queryable<T>().Where(predicate);
        if (!string.IsNullOrEmpty(orderBy))
        {
            query = query.OrderBy(orderBy);
        }
        var entities = query.ToList();
        return entities;
    }
}

同樣的，服務層中也作相應的修改：

IService.cs 文件中的 FindListByClause介面方法：

/// <summary>
/// 根據條件查詢數據
/// </summary>
/// <param name="predicate">條件表達式樹</param>
/// <param name="orderBy">排序</param>
/// <returns>泛型實體集合</returns>
IEnumerable<T> FindListByClause(Expression<Func<T, bool>> predicate, string orderBy = "");

泛型服務類：GenericService.cs 中的 FindListByClause 方法實現：

/// <summary>
/// 根據條件查詢數據
/// </summary>
/// <param name="predicate">條件表達式樹</param>
/// <param name="orderBy">排序</param>
/// <returns>泛型實體集合</returns>
public IEnumerable<T> FindListByClause(Expression<Func<T, bool>> predicate, string orderBy = "")
{
    return _repository.FindListByClause(predicate, orderBy);
}

在開始處理HomeController控制器之前，我們先在項目[TsBlog.Core]中新建兩個幫助類，分別為：HtmlHelper.cs 和 StringHelper.cs。其中代碼分別為：

HtmlHelper.cs:

using System.Text.RegularExpressions;

namespace TsBlog.Core
{
    public static class HtmlHelper
    {
        #region 去掉HTML中的所有標簽,只留下純文本
        /// <summary>

        /// </summary>
        /// <param name="strHtml"></param>
        /// <returns></returns>
        public static string CleanHtml(this string strHtml)
        {
            if (string.IsNullOrEmpty(strHtml)) return strHtml;
            //刪除腳本
            strHtml = Regex.Replace(strHtml, "(\\<script(.+?)\\</script\\>)|(\\<style(.+?)\\</style\\>)", "", RegexOptions.IgnoreCase | RegexOptions.Singleline);
            //刪除標簽
            var r = new Regex(@"<\/?[^>]*>", RegexOptions.IgnoreCase);
            Match m;
            for (m = r.Match(strHtml); m.Success; m = m.NextMatch())
            {
                strHtml = strHtml.Replace(m.Groups[0].ToString(), "");
            }
            return strHtml.Trim();
        }

        #endregion
    }
}

        #region

    #endregion
}

在項[TsBlog.ViewModel]中的文章視圖文件[...TsBlog\src\Libraries\TsBlog.ViewModel\Post\PostViewModel.cs]中添加一個新的屬性：Summary，此時的PostViewModel是這樣的：

namespace TsBlog.ViewModel.Post
{
    /// <summary>
    /// 博文視圖實體類
    /// </summary>
    public class PostViewModel
    {
        /// <summary>
        /// ID
        /// </summary>
        public int Id { get; set; }
        /// <summary>
        /// 標題
        /// </summary>
        public string Title { get; set; }
        /// <summary>
        /// 內容
        /// </summary>
        public string Content { get; set; }
        /// <summary>
        /// 作者ID
        /// </summary>
        public string AuthorId { get; set; }
        /// <summary>
        /// 作者姓名
        /// </summary>
        public string AuthorName { get; set; }
        /// <summary>
        /// 創建時間
        /// </summary>
        public string CreatedAt { get; set; }
        /// <summary>
        /// 發佈時間
        /// </summary>
        public string PublishedAt { get; set; }
        /// <summary>
        /// 是否標識已刪除

        public string IsDeleted { get; set; }
        /// <summary>
        /// 是否允許展示
        /// </summary>
        public bool AllowShow { get; set; }
        /// <summary>
        /// 瀏覽量
        /// </summary>
        public int ViewCount { get; set; }

        /// <summary>
        /// 摘要
        /// </summary>
        public string Summary { get; set; }
    }
}

在項目[TsBlog.Frontend]中創建一個名為：Extensions 文件夾，併在其中創建一個文章的靜態擴展類[...\TsBlog.Frontend\Extensions\PostExtension.cs]，同時實現以下靜態擴展方法：

using TsBlog.Core;
using TsBlog.ViewModel.Post;

namespace TsBlog.Frontend.Extensions
{
    public static class PostExtension
    {
        /// <summary>
        /// 格式化文章的視圖實體
        /// </summary>
        /// <param name="model">文章視圖實體類</param>
        /// <returns></returns>
        public static PostViewModel FormatPostViewModel(this PostViewModel model)
        {
            if (model == null)
            {
                return null;
            }

            model.Summary = model.Content
                .CleanHtml()            //去掉所有HTML標簽
                .TruncateString(200, TruncateOptions.FinishWord | TruncateOptions.AllowLastWordToGoOverMaxLength);     //截斷指定長度作為文章摘要
            return model;
        }
    }
}

網站首頁[HomeController]

在首頁的控制器[...TsBlog.Frontend\Controllers\HomeController.cs]中，利用文章服務介面的方法實現首頁文章列表的查詢，代碼如下：

using System.Linq;
using System.Web.Mvc;
using TsBlog.AutoMapperConfig;
using TsBlog.Frontend.Extensions;
using TsBlog.Services;

namespace TsBlog.Frontend.Controllers
{
    public class HomeController : Controller
    {
        /// <summary>
        /// 文章服務介面
        /// </summary>
        private readonly IPostService _postService;
        public HomeController(IPostService postService)
        {
            _postService = postService;
        }
        /// <summary>
        /// 首頁
        /// </summary>
        /// <returns></returns>
        public ActionResult Index()
        {
            var list = _postService.FindHomePagePosts();
            var model = list.Select(x => x.ToModel().FormatPostViewModel());
            return View(model);
        }
    }
}

好了，到此我們的首頁製作與數據綁定等到完成了，按F5運行，我們即可看到本文開篇所示的首頁效果。

文章詳情頁[PostController]

新建一個名為：PostController的控制器，並添加如下代碼：

using System.Web.Mvc;
using TsBlog.AutoMapperConfig;
using TsBlog.Services;

namespace TsBlog.Frontend.Controllers
{
    public class PostController : Controller
    {
        /// <summary>
        /// 文章服務介面
        /// </summary>
        private readonly IPostService _postService;

        public PostController(IPostService postService)
        {
            _postService = postService;
        }

        /// <summary>
        /// 文章詳情
        /// </summary>
        /// <param name="id">文章ID</param>
        /// <returns></returns>
        public ActionResult Details(int id)
        {
            var post = _postService.FindById(id);
            var model = post.ToModel();
            return View(model);
        }
    }
}

再添加文章詳情頁的視圖[...\TsBlog.Frontend\Views\Post\Details.cshtml]，添加如下視圖HTML代碼：

@model TsBlog.ViewModel.Post.PostViewModel
@{
    Layout = null;
}
