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:

技术分享
  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         }
View Code

   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:

技术分享
  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
View Code

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

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

我在实现这个功能的时候,想使用ajax来提交:

在blog控制器中实现添加数据方法:

  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         }
View Code

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:

 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             {

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。
