从零开始，搭建博客系统MVC5+EF6搭建框架（5），博客详情页、留言、轮播图管理、右侧统计博文

一、博客系统进度回顾

上一遍博客介绍到，系统已经实现到了发布以及前台布局展示，接下来就是实现一些，详情页，留言、轮播图管理、右侧博文统计信息实现。

二、博客系统详情页实现

2.1先来看看详情页展示的效果

2.2实现控制器在前台控制器中创建一个Blog的控制器，主要是展示博客分类以及详情页

Action详情页实现：

  1 /// <summary>
  2         /// 详情页
  3         /// </summary>
  4         /// <param name="id"></param>
  5         /// <returns></returns>
  6         public ActionResult Detail(int id)
  7         {
  8             //获取控制器名称
  9             ViewBag.controllername = RouteData.Values["controller"].ToString().ToLower();
 10             var model = BlogArticleServive.getBlogDetails(id);
 11             ViewBag.gblist = GuestbookServices.QueryOrderBy(c => c.blogId == id, c => c.createdate, false).ToPagedList(1, 5);
 12
 13             //发布时间排序
 14             ViewBag.blogtimelist = BlogArticleServive.QueryOrderBy(c => true, c => c.bCreateTime, false);
 15             //评论排序
 16             ViewBag.blogtrafficlist = BlogArticleServive.QueryOrderBy(c => true, c => c.btraffic, false);
 17             //留言排序
 18             string sql = @"select a.*,b.btitle from (select blogId,count(1) as counts  from Guestbook group by blogId) as a
 19 inner join BlogArticle as b
 20 on
 21 b.bID=a.blogId order by counts desc";
 22
 23             ViewBag.blogguestbooklist = GuestbookServices.RunProc<TopgbViewModels>(sql);
 24
 25             return View(model);
 26         }

由于展示的内容比实际存储在数据库中的信息多，所以把所有能展示的信息都放在BlogViewModels中，在blog业务逻辑层单独实现了一个包含上一页 下一页，以及摘要赋值的方法。

由于这一部分需要从详情内容中只保留部分文字，所以这里需要对索取的详情信息做处理，由于详情信息是通过富文本编辑来添加的里面包含了很多html代码信息，所以在common程序集中，创建一个工具类，Tools类来存放，辅助的相关方法。

ReplaceHtmlTag方法：

  1   #region 去除富文本中的HTML标签
  2         /// <summary>
  3         /// 去除富文本中的HTML标签
  4         /// </summary>
  5         /// <param name="html"></param>
  6         /// <param name="length"></param>
  7         /// <returns></returns>
  8         public static string ReplaceHtmlTag(string html, int length = 0)
  9         {
 10             string strText = System.Text.RegularExpressions.Regex.Replace(html, "<[^>]+>", "");
 11             strText = System.Text.RegularExpressions.Regex.Replace(strText, "&[^;]+;", "");
 12
 13             if (length > 0 && strText.Length > length)
 14                 return strText.Substring(0, length);
 15
 16             return strText;
 17         }
 18         #endregion

然后在获取到多有信息，要处理的地方就是用三元运算符来判断，截取前面的文字部分

2.3详情页视图代码

 70 @section scripts
 71 {
 72     <script src="~/Content/lib/laypage/laypage.js"></script>
 73     <script type="text/javascript">
 74         var blogid;
 75         var curr;
 76         $(function () {
 77             $("#blogId").val(@Model.bID);
 78             //运行分页
 79             blogid = $("#blogId").val();
 80             guestbookpage(curr,blogid);
 81         })

 83     function su(data) {
 84         $("#comment").html(data);
 85         $("#blogId").val(@Model.bID);
 86         //setTimeout(function () {
 87         //    if (document.getElementById('textcenter') != null) {
 88         //            //运行分页
 89         //            guestbookpage(1, blogid);
 90         //    }
 91         //}, 3000);
 92         if (document.getElementById('textcenter') != null) {
 93             //运行分页
 94             guestbookpage(1, blogid);
 95         }
 96
 97
 98
 99     }
100
101     //以下将以jquery.ajax为例，演示一个异步分页
102     function guestbookpage(curr,blogid) {
103         $.getJSON('/blog/getGuestbook', {
104             page: curr || 1,
105             blogId: blogid//向服务端传的参数，此处只是演示
106         }, function (res) {
107             //此处仅仅是为了演示变化的内容
108             $("#comments-list").html(res.content);

126     };
127     </script>
128     }
129 

这里博客的详情页也是通过布局页来实现的。

三、博客系统详情页留言实现

3.1留言展示页面效果

先要创建一个类在数据库中创建一个表：

Guestbook类

  1 namespace Wchl.WMBlog.Model.Models
  2 {
  3     public class Guestbook
  4     {
  5
  6         /// <summary>留言表
  7         ///
  8         /// </summary>
  9         public int id { get; set; }
 10
 11         /// <summary>博客ID
 12         ///
 13         /// </summary>
 14         public int? blogId { get; set; }
 15         /// <summary>创建时间
 16         ///
 17         /// </summary>
 18         public DateTime createdate { get; set; }
 19         public string username { get; set; }
 20
 21         /// <summary>手机
 22         ///
 23         /// </summary>
 24         public string phone { get; set; }
 25         /// <summary>qq
 26         ///
 27         /// </summary>
 28         public string QQ { get; set; }
 29
 30         /// <summary>留言内容
 31         ///
 32         /// </summary>
 33         public string body { get; set; }
 34         /// <summary>ip地址
 35         ///
 36         /// </summary>
 37         public string ip { get; set; }
 38
 39         /// <summary>是否显示在前台,0否1是
 40         ///
 41         /// </summary>
 42         public bool isshow { get; set; }
 43
 44         public BlogArticle blogarticle { get; set; }
 45     }
 46 }

GuestbookViewModels展示类：

  1 namespace Wchl.WMBlog.Model.VeiwModels
  2 {
  3     /// <summary>
  4     /// 留言信息展示类
  5     /// </summary>
  6     public class GuestbookViewModels
  7     {
  8         /// <summary>留言表
  9         ///
 10         /// </summary>
 11         public int id { get; set; }
 12
 13         /// <summary>博客ID
 14         ///
 15         /// </summary>
 16         public int? blogId { get; set; }
 17         /// <summary>创建时间
 18         ///
 19         /// </summary>
 20         public DateTime createdate { get; set; }
 21         public string username { get; set; }
 22
 23         /// <summary>手机
 24         ///
 25         /// </summary>
 26         public string phone { get; set; }
 27         /// <summary>qq
 28         ///
 29         /// </summary>
 30         public string QQ { get; set; }
 31
 32         /// <summary>留言内容
 33         ///
 34         /// </summary>
 35         public string body { get; set; }
 36         /// <summary>ip地址
 37         ///
 38         /// </summary>
 39         public string ip { get; set; }
 40
 41         /// <summary>是否显示在前台,0否1是
 42         ///
 43         /// </summary>
 44         public bool isshow { get; set; }
 45
 46         public BlogArticle blogarticle { get; set; }
 47     }
 48 }

GuestbookMap字段约束:

  1
  2 namespace Wchl.WMBlog.Model.Maps
  3 {
  4     public class GuestbookMap: EntityTypeConfiguration<Guestbook>
  5     {
  6         public GuestbookMap() {
  7             this.HasKey(p => p.id);
  8             //设置外键
  9             this.HasRequired(p => p.blogarticle).WithMany().HasForeignKey(p => p.blogId);
 10         }
 11     }
 12 }

接下来就是创建相应的仓储接口、实现，服务接口、实现，这里就不一一介绍了，跟上一篇实现博客类的是一样的。

我在实现这个功能的时候，想使用ajax来提交：

这里我把所有留言的内容放在一个部分视图页

_GuestbookPage代码：

  1 <article>
  2     <div spellcheck="false" class="example">
  3         <div class="comments">
  4             <header>
  5                 <div class="pull-right"><a href="#commentReplyForm2" class="btn btn-primary"><i class="icon-comment-alt"></i> 发表评论</a></div>
  6                 <h3>所有评论</h3>
  7             </header>
  8             <section class="comments-list" id="comments-list">
  9               @{ if (ViewBag.gblist != null)
 10                   {
 11                       foreach (var list in ViewBag.gblist)
 12                       {
 13                         <div class="comment">
 14                             <a href="###" class="avatar">
 15                                 <i class="icon-user icon-2x"></i>
 16                             </a>
 17                             <div class="content">
 18                                 <div class="pull-right text-muted">@list.createdate</div>
 19                                 <div><a href="###"><strong>@list.username</strong></a></div>
 20                                 <div class="text">@list.body</div>
 21                                 <div class="actions">
 22                                     <a href="##">回复</a>
 23                                 </div>
 24                             </div>
 25                         </div>
 26                       }
 27                   }
 28
 29             }
 30             </section>
 31             <br />
 32             <div class="text-center" id="textcenter">
 33
 34             </div>
 35             <footer>
 36                 <div class="reply-form" id="commentReplyForm2">
 37                     <a href="###" class="avatar"><i class="icon-user icon-2x"></i></a>
 38                     @using (Ajax.BeginForm("addGuestbook", "Blog", new AjaxOptions()
 39                     {
 40                         HttpMethod = "post",
 41                         OnSuccess="su"
 42

 44                     {

 77     </div>
 78 </article>

其中分为两部分，一部分是输入留言，一部分是展示信息。

留言提交的表单如下：

在blog控制器中实现添加数据方法：

  1         /// <summary>
  2         ///提交评论
  3         /// </summary>
  4         /// <param name="model"></param>
  5         /// <returns></returns>
  6         [HttpPost]
  7         public ActionResult addGuestbook(GuestbookViewModels model)
  8         {
  9             model.createdate = DateTime.Now;
 10             model.ip = Request.UserHostAddress;
 11             //AutoMapper自动映射
 12             Mapper.Initialize(cfg => cfg.CreateMap<GuestbookViewModels, Guestbook > ());
 13             Guestbook models = Mapper.Map< GuestbookViewModels, Guestbook> (model);
 14             BlogArticle blogArticle = BlogArticleServive.QueryWhere(a => a.bID == model.blogId).FirstOrDefault();
 15             blogArticle.bcommentNum += 1;
 16             BlogArticleServive.SaverChanges();
 17             GuestbookServices.Add(models);
 18             GuestbookServices.SaverChanges();
 19             ViewBag.gblist = GuestbookServices.QueryOrderBy(c => c.blogId == model.blogId, c => c.createdate, false).ToPagedList(1, 5);
 20             return PartialView("_GuestbookPage");
 21         }

执行成功之后就把信息加载到分页信息的位置。

3.2添加实现之后就是展示数据，展示数据使用的是一个js分页插件laypage.js

在mvc的视图中只能在页面有一个model类，所以就只能使用ViewBag.gblist来传值了，本来这个打算用mvcpager插件，结果发现不行，就只能使用js来分页，实现如下：

后台blog控制器下，实现分页，然后拼接数据：

  1 /// <summary>
  2         /// js分页实现
  3         /// </summary>
  4         /// <param name="page"></param>
  5         /// <param name="blogId"></param>
  6         /// <returns></returns>
  7         public ActionResult getGuestbook(int page,int blogId)
  8         {
  9             StringBuilder sb = new StringBuilder();
 10             int pages = 0;
 11             var modelsLists = GuestbookServices.QueryByPage(page, 5,out pages, c => c.blogId == blogId, c => c.createdate, false);
 12             foreach (var item in modelsLists)
 13             {
 14                 sb.AppendFormat(@"<div class='comment'>
 15 <a href = '###' class='avatar'>
 16 <i class='icon-user icon-2x'></i>
 17 </a>
 18 <div class='content'>
 19 <div class='pull-right text-muted'>{0}</div>
 20 <div><a href = '###' ><strong > {1}</strong ></a ></div>
 21 <div class='text'>{2}</div>
 22 <div class='actions'>
 23 <a href = '##' > 回复 </a>
 24 </div >
 25 </div >
 26 </div >",item.createdate,item.username,item.body);
 27             }
 28             if (pages % 5 == 0)
 29             {
 30                 pages = pages / 5;
 31             }
 32             else
 33             {
 34                 pages = (pages / 5)+1;
 35             }
 36
 37
 38             return Json(new {
 39                 content = sb.ToString(),
 40                 pages= pages
 41             });
 42         }

在详情页中直接调用就可以了实现分页了

四、博客系统广告轮播图管理实现

4.1实现效果这里的轮播图使用的是zui中组件来实现的，

4.2主页轮播图视图中的代码实现

4.3轮播图管理后台页面实现展示

这里上传图片使用的是百度的上传控件

视图页代码实现:

  1
  2 @{
  3     ViewBag.Title = "广告管理";
  4 }
  5 @section stylesheet{
  6     <link href="~/Content/CSS/blogArticleStyle.css" rel="stylesheet" />

广告对应的表的类Advertisement：

  1 namespace Wchl.WMBlog.Model.Models
  2 {
  3     public class Advertisement
  4     {
  5         /// <summary>
  6         /// 分类ID
  7         /// </summary>
  8         public int Id { get; set; }
  9         /// <summary>
 10         /// 创建时间
 11         /// </summary>
 12         public DateTime Createdate { get; set; }
 13
 14         /// <summary>
 15         /// 广告图片
 16         /// </summary>

 29         /// <summary>
 30         /// 备注
 31         /// </summary>
 32         public string Remark { get; set; }
 33     }
 34 }

展示类AdvertisementViewModels:

  1 namespace Wchl.WMBlog.Model.VeiwModels
  2 {
  3     /// <summary>
  4     /// 广告类
  5     /// </summary>
  6     public class AdvertisementViewModels

  8         /// <summary>
  9         /// 分类ID
 10         /// </summary>
 11         public int Id { get; set; }
 12         /// <summary>
 13         /// 创建时间

 24         /// </summary>
 25         public string Title { get; set; }
 26
 27         /// <summary>
 28         /// 广告链接
 29         /// </summary>
 30         public string Url { get; set; }

 34         /// </summary>
 35         public string Remark { get; set; }
 36     }
 37 }

表约束AdvertisementMap:

  1 namespace Wchl.WMBlog.Model.Maps
  2 {
  3     public class AdvertisementMap: EntityTypeConfiguration<Advertisement>
  4     {
  5         public AdvertisementMap()
  6         {
  7             this.HasKey(p => p.Id);
  8             this.Property(p => p.ImgUrl).HasMaxLength(512);
  9             this.Property(p => p.Title).HasMaxLength(64);
 10             this.Property(p => p.Url).HasMaxLength(256);
 11         }
 12     }
 13 }

这里实现的是添加图片自动上传：

五、博客系统右侧统计

5.1效果显示，这里的统计主要是对发布时间、阅读排行、评论排行做了统计。

后台实现代码：

部分布局视图代码：

这里重点讲讲怎么在EF中执行SQL语句：

在仓储父类的实现中这里传入的实体就是需要展示表内容的类：

六、博客系统小结

现阶段博客系统已经完成了前台展示，后台发布基本功能，接下来打算在后台添加一个权限模块，个人能力有限，代码水平不够好，也许我这样的代码还入不了大神的法眼，等我把权限做完之后，我会一点一点的来修改代码。

其实我写代码的时间不长，主要是每次想功能怎么实现的时候，要把每一步都想到，感觉编程，真正实现功能的开发编码的时间只有40%左右。

如果大家对这个有什么意见和想法，可以提出来，我会尽量，去修改的，谢谢了。

补充内容：

根据园友提出的补漏部分说明：

这个QueryByBeginPage是在仓储层写的一个查询分页的功能，是为了配合DataTables使用的。

  1        /// <summary>
  2         /// 从第几条开始用于DataTables
  3         /// </summary>
  4         /// <typeparam name="TKey"></typeparam>
  5         /// <param name="pageIndex">第几页开始</param>
  6         /// <param name="pagesize">一页几条</param>
  7         /// <param name="rowcount">一共多少条</param>
  8         /// <param name="predicate">条件</param>
  9         /// <param name="keySelector">排序关键字</param>
 10         /// <param name="IsQueryOrderBy">升序还是降序</param>
 11         /// <returns></returns>
 12         public List<TEntity> QueryByBeginPage<TKey>(int pageIndex, int pagesize, out int rowcount, Expression<Func<TEntity, bool>> predicate, Expression<Func<TEntity, TKey>> keySelector, bool IsQueryOrderBy)
 13         {
 14             rowcount = _dbSet.Count(predicate);
 15             if (IsQueryOrderBy)
 16             {
 17                 return _dbSet.Where(predicate).OrderBy(keySelector).Skip(pageIndex).Take(pagesize).ToList();
 18             }
 19             else
 20             {
 21                 return _dbSet.Where(predicate).OrderByDescending(keySelector).Skip(pageIndex).Take(pagesize).ToList();
 22             }
 23         }

这个TopgbViewModels是查询统计留言排行用的一个类，是根据你数据库查询出来表建的相应的类

  1 /// <summary>
  2     /// 留言排名展示类
  3     /// </summary>
  4     public class TopgbViewModels
  5     {
  6         /// <summary>博客ID
  7         ///
  8         /// </summary>
  9         public int? blogId { get; set; }
 10
 11         /// <summary>
 12         /// 评论数量
 13         /// </summary>
 14         public int counts { get; set; }
 15
 16         /// <summary>博客标题
 17         ///
 18         /// </summary>
 19         public string btitle { get; set; }
 20     }

有什么不明白的地方都可以跟我留言，我会尽量写清楚点，让大家看的明白点。
