[ASP.net教程]从零开始,搭建博客系统MVC5+EF6搭建框架(4)下,前后台布局实现、发布博客以及展示。


一、博客系统进度回顾

   目前已经完成了,前台展示,以及后台发布的功能,最近都在做这个,其实我在国庆的时候就可以弄完的,但是每天自己弄,突然最后国庆2天,连电脑都不想碰,所以就一直拖着,上一篇写了前端实现用到的一些WebUI框架以及一些系统中用到的js插件,其实写了这么久,还是第一次,有人留言,不要烂尾的,感觉还是有点点价值的,至少有人关注。

  废话不多说,现在开始上代码。

二、博客系统后台布局实现

  2.1.这里所用的是MVC的布局页来实现的,后台主要分为三部分:导航、菜单、主要内容

代码实现:

   这里把后台单独放在一个区域里面,所以我这里建立一个admin的区域

在布局页_Layout.cshtml引入公共的一些css文件以及js文件

布局页代码_Layout.cshtml:

其实我这个菜单选中的效果做的很垃圾,我自己都觉得不要,但是目前我也只能想到这个方法,因为每次加载一个嵌套的页面就会从新去加载一次布局页_Layout.cshtml的内容,我这个菜单是有一个active选中的样式的,这个是菜单插件里面已经写好了,这里遇到的问题就是每次刷新都会把页面选中效果设置到默认的菜单上,假如点击了发布博客菜单应该显示博客管理这个菜单内容,但是从新加载的时候就会回到默认的系统统计菜单上,所以这里就用地址路径来判断应该显示那个菜单,方法真的很笨,见谅,各位。

2.2博客信息添加功能实现

   在model层的Models文件创建一个BlogArticle类,然后在创建一个文件VeiwModels,Models文件夹里面的类是用来生成数据库对应的表,而VeiwModels文件夹里面对应的类是用来在view视图页面展示数据用的,当你一个表字段很多不需要所有数据都展示,或者要做一些处理计算的类,这样就需要一个VeiwModels类来分离。

BlogArticle类:

 1 namespace Wchl.WMBlog.Model.Models 2 { 3   /// <summary>博客文章 4   ///  5   /// </summary 6   public class BlogArticle 7   { 8     /// <summary> 9     ///  10     /// </summary> 11     public int bID { get; set; } 12     /// <summary>创建人 13     ///  14     /// </summary> 15     public string bsubmitter { get; set; } 16  17     /// <summary>博客标题 18     ///  19     /// </summary> 20     public string btitle { get; set; } 21  22     /// <summary>类别 23     ///  24     /// </summary> 25     public string bcategory { get; set; } 26  27     /// <summary>内容 28     ///  29     /// </summary> 30     public string bcontent { get; set; } 31  32     /// <summary> 33     /// 访问量 34     /// </summary> 35     public int btraffic { get; set; } 36  37     /// <summary> 38     /// 评论数量 39     /// </summary> 40     public int bcommentNum { get; set; } 41  42     /// <summary> 修改时间 43     ///  44     /// </summary> 45     public DateTime bUpdateTime { get; set; } 46  47     /// <summary> 48     /// 创建时间 49     /// </summary> 50     public System.DateTime bCreateTime { get; set; } 51     /// <summary>备注 52     ///  53     /// </summary> 54     public string bRemark { get; set; } 55   } 56 }

在maps文件夹中添加相应的约束

BlogArticleMap类:

 1 namespace Wchl.WMBlog.Model.Maps 2 { 3   public class BlogArticleMap: EntityTypeConfiguration<BlogArticle> 4   { 5     public BlogArticleMap() 6     { 7       this.HasKey(p => p.bID); 8       this.Property(p => p.btitle).HasMaxLength(256); 9       this.Property(p => p.bsubmitter).HasMaxLength(60); 10       this.Property(p => p.bcontent).HasColumnType("Text").IsMaxLength(); 11     } 12   } 13 }

View Code

然后在控制台使用更新数据库命令:update database -force,一定要选择model层

创建好了表,然后就是在仓储层以及业务层创建相应的接口和实现类

IBlogArticleRepository类:

 1 namespace Wchl.WMBlog.IRepository 2 { 3   public interface IBlogArticleRepository:IBaseRepository<BlogArticle> 4   { 5   } 6 } 7 

View Code

BlogArticleRepository类:

 1 namespace Wchl.WMBlog.Repository 2 { 3   public class BlogArticleRepository: BaseRepository<BlogArticle>, IBlogArticleRepository 4   { 5   } 6 }

View Code

IBlogArticleServices类:

 1 namespace Wchl.WMBlog.IServices 2 { 3   public interface IBlogArticleServices: IBaseServices<BlogArticle> 4   { 5     /// <summary> 6     /// 获取视图博客详情信息 7     /// </summary> 8     /// <param name="id"></param> 9     /// <returns></returns> 10     BlogViewModels getBlogDetails(int id); 11   } 12 }

2.3博客添加页面实现功能

在区域admin的控制器下创建一个add方法用来展示页面。

add方法

 1     public ActionResult Add() 2     { 3       return View(); 4     }

View Code

然后View添加视图选择使用布局页

在控制器中添加一个上传图片的方法,用于富文本编辑器上传图片

upload方法

 1    //图片上传 2     public ActionResult upload() 3     { 4       //文件保存目录路径 5       String savePath = "/upload/"; 6  7       //定义允许上传的文件扩展名 8       Hashtable extTable = new Hashtable(); 9       extTable.Add("image", "gif,jpg,jpeg,png,bmp"); 10       extTable.Add("flash", "swf,flv"); 11       extTable.Add("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb"); 12       extTable.Add("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2"); 13  14       //最大文件大小 15       int maxSize = 1000000; 16  17       HttpPostedFileBase imgFile = Request.Files["imgFile"]; 18       if (imgFile == null) 19       { 20         return Content("error|请选择文件。"); 21       } 22  23       String dirPath = Server.MapPath(savePath); 24       if (!Directory.Exists(dirPath)) 25       { 26         return Content("error|上传目录不存在。"); 27       } 28  29       String dirName = Request.QueryString["dir"]; 30       if (String.IsNullOrEmpty(dirName)) 31       { 32         dirName = "image"; 33       } 34       if (!extTable.ContainsKey(dirName)) 35       { 36         return Content("error|目录名不正确。"); 37       } 38  39       String fileName = imgFile.FileName; 40       String fileExt = Path.GetExtension(fileName).ToLower(); 41  42       if (imgFile.InputStream == null || imgFile.InputStream.Length > maxSize) 43       { 44         return Content("error|上传文件大小超过限制。"); 45       } 46  47       if (String.IsNullOrEmpty(fileExt) || Array.IndexOf(((String)extTable[dirName]).Split(','), fileExt.Substring(1).ToLower()) == -1) 48       { 49         return Content("error|上传文件扩展名是不允许的扩展名。\n只允许" + ((String)extTable[dirName]) + "格式。"); 50       } 51  52       //创建文件夹 53       dirPath += dirName + "/"; 54       if (!Directory.Exists(dirPath)) 55       { 56         Directory.CreateDirectory(dirPath); 57       } 58       String ymd = DateTime.Now.ToString("yyyyMMdd", DateTimeFormatInfo.InvariantInfo); 59       dirPath += ymd + "/"; 60       if (!Directory.Exists(dirPath)) 61       { 62         Directory.CreateDirectory(dirPath); 63       } 64  65       String newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt; 66       String filePath = dirPath + newFileName; 67  68       imgFile.SaveAs(filePath); 69  70       String fileUrl = savePath + "image/" + ymd + "/" + newFileName; 71       return Content(fileUrl); 72     }

提交博客使用的是异步提交

在博客控制器添加一个add方法用来添加数据

add方法

 1     //新增博文 2     [HttpPost] 3     [ValidateInput(false)] 4     public ActionResult Add(BlogArticle blogArticle) 5     { 6       blogArticle.bCreateTime = DateTime.Now; 7       blogArticle.bsubmitter = "admin"; 8       blogArticle.bUpdateTime = DateTime.Now; 9       blogArticle.bRemark = string.Empty; 10       BlogArticleServive.Add(blogArticle); 11       BlogArticleServive.SaverChanges(); 12       return Content("ok:添加成功!"); 13     }

三、博客系统前台布局实现

3.1接下来就改前台展示部分,同样使用的是布局页

设计页面如下:

前台布局页_Layout.cshtml代码:

3.2实现主页面展示

在控制器下的文件夹中创建一个home控制器,然后创建一个index视图页面

index视图页代码

然后在控制器index下实现查询博客信息代码

 1 public ActionResult Index(int pageindex = 1) 2     { 3       //获取控制器名称 4       ViewBag.controllername = RouteData.Values["controller"].ToString().ToLower(); 5  6       int pagesize = 6; 7       //获取发布博文信息 8       var blogArticleList = BlogArticleServive.QueryWhere(a => true).OrderByDescending(a => a.bCreateTime).ToPagedList(pageindex, pagesize); 9       foreach (var item in blogArticleList) 10       { 11         if (!string.IsNullOrEmpty(item.bcontent)) 12         { 13           item.bcontent = Tools.ReplaceHtmlTag(item.bcontent); 14           if (item.bcontent.Length > 200) 15           { 16             item.bcontent = item.bcontent.Substring(0, 200); 17           } 18         } 19  20       } 21       //获取轮播广告新 22       ViewBag.adList = AdvertisementServices.QueryOrderBy(a => true, a => a.Createdate, false).ToPagedList(1, 3); 23       //发布时间排序 24       ViewBag.blogtimelist = BlogArticleServive.QueryOrderBy(c => true, c => c.bCreateTime, false); 25       //评论排序 26       ViewBag.blogtrafficlist = BlogArticleServive.QueryOrderBy(c => true, c => c.btraffic, false); 27       //留言排序 28       string sql = @"select a.*,b.btitle from (select blogId,count(1) as counts from Guestbook group by blogId) as a 29 inner join BlogArticle as b 30 on 31 b.bID=a.blogId order by counts desc"; 32  33       ViewBag.blogguestbooklist = GuestbookServices.RunProc<TopgbViewModels>(sql); 34  35  36       return View(blogArticleList); 37     }

四、博客系统发布博客功能以及展示功能总结

    这里使用到了的两个插件一个是后台的富文本编辑器;一个是mvc分页插件,具体插件可以去相应的官网查看详细的使用方法,富文本编辑器官网:http://www.wangeditor.com/;mvc分页插件官网:http://www.webdiyer.com/mvcpager/

     主要的分布实现是使用到了mvc布局页来实现的,实现页面功能的时候,一般都是先把静态页面做出来,然后在把前台页面移至到项目中,把需要展示数据的地方修改成动态的就可以了。

    这里在说明一下我的文件夹设计我在Content文件夹下创建了CSS、fonts、images、JS、lib文件夹,把所有自定和用到的主要UI框架文件分类放在对应的文件夹中,lib文件夹主要放所有的第三方的插件文件,另外还添加了一个upload文件夹主要存放所有上传的文件图片的。

    以上博客中使用的文字信息来之IT之家网站,页面布局都是传统的布局方式,风格参考我的博客园的风格。

    下一篇博客会介绍系统中留言、轮播图管理的实现,我会的也就这么多了,希望大家多提提意见,有什么不够好的地方我会尽量改正的,谢谢大家。
