为BlogEngine的分类增加自定义Url别名功能

这次为BlogEngine的分类增加了自定义Url别名功能：

有疑问请留言，谢谢

 

修改代码：

BlogEngine.Core.Category.cs

在56行
        private string _Title;
        /**//// <summary>
        /// Gets or sets the Title or the object.
        /// </summary>
        public string Title
        ...{
            get ...{ return _Title; }
            set
            ...{
                if (_Title != value) MarkChanged("Title");
                _Title = value;
            }
        }
后添加：
        private string _Slug;
        /**//// <summary>
        /// Gets or sets the Slug or the object.
        /// </summary>
        public string Slug
        ...{
            get ...{ return _Slug; }
            set
            ...{
                if (_Slug != value) MarkChanged("Slug");
                _Slug = value;
            }
        }
        public Category(string title, string description,string slug)
        ...{
            this.Id = Guid.NewGuid();
            this._Title = title;
            this._Description = description;
            this._Slug = slug;
            this.Parent = null;
        }
修改BlogEngine.Core.Providers.Categories.cs的
public override void InsertCategory(Category category),
public override void UpdateCategory(Category category),
public override void DeleteCategory(Category category)这些方法中作相应的修改
                foreach (Category cat in categories)
                ...{
                    writer.WriteStartElement("category");
                    writer.WriteAttributeString("id", cat.Id.ToString());
                    writer.WriteAttributeString("description", cat.Description);
                    writer.WriteAttributeString("parent", cat.Parent.ToString());
                    writer.WriteAttributeString("slug", cat.Slug.ToString());//新增加的Url别名
                    writer.WriteValue(cat.Title);
                    writer.WriteEndElement();
                    cat.MarkOld();
                }

修改public override List<Category> FillCategories()方法：
在               
category.Id = new Guid(node.Attributes["id"].InnerText);
category.Title = node.InnerText;
后添加
if (node.Attributes["slug"] != null)
    category.Slug = node.Attributes["slug"].InnerText;
else
    category.Slug = string.Empty;

修改BlogEngine.Core.Web.HttpModules.UrlRewrite.cs中的private static void RewriteCategory(HttpContext context, string url)
        private static void RewriteCategory(HttpContext context, string url)
        ...{
            string title = ExtractTitle(context, url);
            foreach (Category cat in Category.Categories)
            ...{
                //string legalTitle = Utils.RemoveIllegalCharacters(cat.Title).ToLowerInvariant();
                string legalTitle = Utils.RemoveIllegalCharacters(cat.Slug).ToLowerInvariant();
                if (title.Equals(legalTitle, StringComparison.OrdinalIgnoreCase))
                ...{
                    context.RewritePath(Utils.RelativeWebRoot + "default.aspx?id=" + cat.Id.ToString() + GetQueryString(context), false);
                    break;
                }
            }
        }

修改BlogEngine.Web/App_Code/Controls/CategoryList.cs中private HtmlGenericControl BindCategories()这个方法
129行开始：
    HtmlAnchor anc = new HtmlAnchor();
    //anc.HRef = Utils.RelativeWebRoot + "category/" + Utils.RemoveIllegalCharacters(key) + BlogSettings.Instance.FileExtension;
                anc.HRef = Utils.RelativeWebRoot + "category/" + Utils.RemoveIllegalCharacters(GetSlug(new Guid(dic[key].ToString()))) + BlogSettings.Instance.FileExtension;
    anc.InnerHtml = HttpUtility.HtmlEncode(key) + postCount;
    anc.Title = "Category: " + key;

修改BlogEngine.Web/admin/pages/Categories.aspx
在"<asp:TextBox runat="Server" ID="txtNewCategory" Width="200" /><br />"后添加：
    <asp:Label ID="lblNewSlug" runat="server" AssociatedControlID="txtNewSlug" Text="Slug" /><br />
    <asp:TextBox runat="Server" ID="txtNewSlug" Width="200" /><br />

在" 
           <asp:TemplateField HeaderText="<%$ Resources:labels, name %>">
                <ItemTemplate>
                    <%# Server.HtmlEncode(Eval("title").ToString()) %>
                </ItemTemplate>
                <EditItemTemplate>
                    <asp:TextBox runat="server" ID="txtTitle" Text='<%# Eval("title") %>' />
                </EditItemTemplate>
            </asp:TemplateField>
"后添加：
            <asp:TemplateField HeaderText="Slug">
                <ItemTemplate>
                    <%# Server.HtmlEncode(Eval("slug").ToString())%>
                </ItemTemplate>
                <EditItemTemplate>
                    <asp:TextBox runat="server" ID="txtSlug" Text='<%# Eval("slug") %>' />
                </EditItemTemplate>
            </asp:TemplateField>

修改BlogEngine.Web/admin/pages/Categories.aspx.cs中 void btnAdd_Click(object sender, EventArgs e)这个方法
将Category cat = new Category(txtNewCategory.Text, description);改成
string slug = txtNewSlug.Text;
            if (slug.Length > 255)
                slug = slug.Substring(0, 255);
Category cat = new Category(txtNewCategory.Text, description, slug);

修改 void grid_RowUpdating(object sender, GridViewUpdateEventArgs e)方法：
 

  Guid id = (Guid)grid.DataKeys[e.RowIndex].Value;
  TextBox textboxTitle = (TextBox)grid.Rows[e.RowIndex].FindControl("txtTitle");
  TextBox textboxSlug = (TextBox)grid.Rows[e.RowIndex].FindControl("txtSlug");//新增加的
  TextBox textboxDescription = (TextBox)grid.Rows[e.RowIndex].FindControl("txtDescription");
  DropDownList ddlParent = (DropDownList)grid.Rows[e.RowIndex].FindControl("ddlParent");
  Category cat = Category.GetCategory(id);
  cat.Title = textboxTitle.Text;
  cat.Slug = textboxSlug.Text;//新增加的
  cat.Description = textboxDescription.Text;
  if (ddlParent.SelectedValue == "0")
   cat.Parent = null;
  else
   cat.Parent = new Guid(ddlParent.SelectedValue);
  cat.Save();

  Response.Redirect(Request.RawUrl);

到这里就修改完成了，改的东西有点多，比较烦，因为我打算对BlogEngine进行比较多的修改，所以暂时不提供修改的文件下载，等感觉改得差不多了再提供下载
