接着 博客转发小工具2 ，又弄了一个第三版。主要功能有：博客备份到本地、浏览备份到本地的博客、关键字搜索本地的博客和转发博客可以选择个人分类 填写Tag标签。其实想了想，转发博客干嘛非要在本地客户端转发，直接在博客园的页面用js不就可以达到目的么。想是这么想，还没尝试。等我写完了这个博客就去试试。。继续回到这个小工具，说实在的本人做的这个小工具界面丑的那是、、反正就是很丑很丑啦。没办法，没有美工的那种艺术细胞。还有就是，整个功能其实真没什么技术含量，还是html的抓取，winfrom在工作中也没用过，就平时偶尔玩玩，望大神们勿喷~~。
不过我觉得这个小工具的作用：第一、可以用来备注自己的博客，自己留个底。第二、某些朋友的工作环境可能没有外网（我以前的公司就没有），这样的话可以用来备份一些博友的系类文章当资料。【要是可以的话，把系类文章导成dpf文档那就更爽了。可是我一直没成功~】。
也许有写人会说：啥啥啥的早就有类似的软件了。我不知道，我没用过，我觉得自己做的用着开心。就当练手吧。
开始说内容了。
功能一：备份博客到本地
备份的博客是博客园推荐的前150个。也可以自己手动输入要备份的url。
1.加载推荐博客
var docment = new HtmlAgilityPack.HtmlDocument();docment.LoadHtml(BlogCommon.PostReqest(BlogUrlString.推荐博客url));var nodes = docment.DocumentNode.SelectNodes("//ul//a");List<object> list = new List<object>();for (int i = 0; i < nodes.Count; i++){ var url = "http://www.cnblogs.com" + nodes[i].Attributes["href"].Value; var name = "NO." + (i + 1).ToString() + " " + nodes[i].InnerText; list.Add(new { url = url, name = name });}list_tuijian.DataSource = list;list_tuijian.ValueMember = "url";list_tuijian.DisplayMember = "name";
2.加载随笔分类、档案和标签
首先选中博客改变url，然后url文本框的TextChanged事件里面加载 随笔分类、档案和标签数据。
var docment = new HtmlAgilityPack.HtmlDocument();docment.LoadHtml(BlogCommon.GetRequest(BlogUrlString.个人博客分类url(strname)));//加载随笔类型LoadTree(docment, "//div[@class='catListPostCategory']//a", tree_suibiType, "随笔分类");tree_suibiType.CheckBoxes = true;// 加载随笔档案LoadTree(docment, "//div[@class='catListPostArchive']//a", tree_suibiTime, "随笔档案");tree_suibiTime.CheckBoxes = true;//// 加载文章类型//LoadTree(docment, "//div[@class='catListArticleCategory']//a", tree_wenzhangType, "文章类型");//tree_suibiType.CheckBoxes = true;docment.LoadHtml(BlogCommon.GetRequest(BlogUrlString.标签url(strname)));// 加载文章类型LoadTree(docment, "//div[@id='taglist']//a", tree_tag, "标签");tree_tag.CheckBoxes = true;
public void LoadTree(HtmlAgilityPack.HtmlDocument docment, string where, TreeView trre, string TreeName){ try { trre.Nodes.Clear(); var nodes = docment.DocumentNode.SelectNodes(where); if (nodes == null || nodes.Count <= 0) return; List<object> list = new List<object>(); TreeNode treenodeS = new TreeNode() { Name = "", Text = TreeName }; for (int i = 0; i < nodes.Count; i++) { TreeNode treenode = new TreeNode(); var url = nodes[i].Attributes["href"].Value; var name = nodes[i].InnerText; list.Add(new { url = url, name = name }); treenode.Text = name; treenode.Name = url; treenodeS.Nodes.Add(treenode); } trre.Nodes.Add(treenodeS); trre.ExpandAll();//展开节点 } catch (Exception ex) { MessageBox.Show("加载" + TreeName + "错误" + ex.Message); }}
3.点击备份
点击备份，读取选中的复选框所包含的所有url。
#region 获取某个选中树节点 的所有url地址 public List<string[]> getShuibiType_all_url(string url, ref List<string[]> list_urlS) { label1.Text = "正在读取" + url; var docment = new HtmlAgilityPack.HtmlDocument(); docment.LoadHtml(BlogCommon.GetRequest(url)); // a class entrylistItemTitle entrylistTitle var nodes = docment.DocumentNode.SelectNodes("//div[@class='entrylist']//div[@class='entrylistPosttitle']//a"); if (nodes == null) nodes = docment.DocumentNode.SelectNodes("//div[@id='content']//div[@class='post post-list-item']/h2/a"); var entrylistTitle = docment.DocumentNode.SelectNodes("//h1[@class='entrylistTitle']"); if (entrylistTitle == null) entrylistTitle = docment.DocumentNode.SelectNodes("//div[@id='content']/h2"); var posts_title = entrylistTitle != null ? entrylistTitle[0].InnerText : "未分类"; if (nodes != null && nodes.Count > 0) { for (int j = 0; j < nodes.Count; j++) { label1.Text = "正在读取[" + posts_title + "]" + (j + 1) + "/" + nodes.Count + "页" + "url地址"; list_urlS.Add( new string[] { nodes[j].Attributes["href"].Value, nodes[j].InnerText, entrylistTitle.Count>=1?entrylistTitle[0].InnerText:"未分类" }); } } return list_urlS; } #endregion
点击备份，保存到本地。
#region 保存内容到文件 /// <summary> /// 保存内容到文件 /// </summary> /// <param name="list_str">根据地址集合</param> /// <param name="type"></param> /// <param name="docment"></param> public void SaveFile(List<string[]> list_str, string type, HtmlAgilityPack.HtmlDocument docment) { if (list_str == null || list_str.Count <= 0) return; for (int i = 0; i < list_str.Count; i++) { var url = list_str[i][0]; var name = url.Split('/').Length >= 4 ? url.Split('/')[3] : "未分类"; if (list_str[i].Length == 3) { try { label1.Text = "正在请求[" + name + "/" + type + "]页面" + (i + 1) + "/" + list_str.Count + "。"; #region 文件路径处理 //过滤文件名的特殊字符 string[] rep = new string[] { "—", ":", "<", ">", "?", "*", "/", "|", "\"" }; string fileNmae = list_str[i][1].Replace("\\", string.Empty); for (int j = 0; j < rep.Length; j++) { if (rep[j].Length == 0) continue; fileNmae = fileNmae.Replace(rep[j], string.Empty); } var Paht = ForwardPath + name + "\\" + type + "\\" + list_str[i][2] + "\\"; for (int j = 0; j < rep.Length; j++) { if (rep[j].Length == 0) continue; Paht = Paht.Replace(rep[j], string.Empty); } Paht = FileHelp.PathBlogs + Paht; var FilePath = Paht + fileNmae + ".html"; #endregion if (radioButton2.Checked && File.Exists(FilePath)) { label1.Text = "页面数据存在[" + name + "/" + type + "]页面" + (i + 1) + "/" + list_str.Count + "。"; continue; } var html = BlogCommon.GetRequest(url); docment.LoadHtml(html); var Nodes = docment.DocumentNode.SelectNodes("//div[@class='postBody']"); if (Nodes == null) Nodes = docment.DocumentNode.SelectNodes("//div[@id='cnblogs_post_body']"); html = Nodes[0].InnerHtml; docment.DocumentNode.InnerHtml = "<div id='my_html_postBody'>" + html + "</div>"; #region 去掉a标签的超链接 //去掉a标签的超链接 var html_aS = docment.DocumentNode.SelectNodes("//a"); if (html_aS != null) for (int z = 0; z < html_aS.Count; z++) if (html_aS[z].Attributes["href"] != null && html_aS[z].Attributes["href"].Value[0] != '#') html_aS[z].Attributes["href"].Value = "javascript:void()"; #endregion label1.Text = "准备保存[" + name + "/" + type + "]内容" + (i + 1) + "/" + list_str.Count + "~"; FileHelp.CreatePath(Paht + @"imgs\"); saveImg(docment, Paht + @"imgs\", label1.Text + "..."); docment.CreateAttribute("url", url); //profile_block docment.DocumentNode.InnerHtml = "<div id='mytext_url'>" + url + "</div>" + "<div id='mytext_BlogTitleName'>" + name + "</div>" + docment.DocumentNode.InnerHtml; docment.Save(FilePath, Encoding.UTF8); File.SetCreationTime(FilePath, new DateTime(FileHelp.Ticks)); LuceneHelp.CreateIndexFilePath(FilePath); //FileHelps.SaveFile(Paht, fileNmae + ".txt", html); label1.Text = "保存成功" + (i + 1) + "/" + list_str.Count + "。"; } catch (Exception ex) { string mess = url + "\r\n" + ex.Message + "\r\n" + ex.StackTrace + "\r\n\r\n"; string myPath = FileHelp.PathBlogs + ForwardPath + name + "\\" + type + "\\"; FileHelp.SaveFile(myPath, "err.txt", mess, false); } } else FileHelp.SaveFile(FileHelp.PathBlogs + ForwardPath + name + "\\" + type + "\\", "err.txt", "异常373位置", false); } } #endregionView Code
功能二：浏览本地博客
1.递归加载目录下所以博客文件
（这个方法不行，如果文件多的话，会有点卡。以后要改成点击加载下层目录）
public TreeNodeCollection loadTree(string path, TreeNodeCollection treeS, bool isNe = true){ List<string[]> list = FileHelp.FileSystemInfo(path, "3"); string[] str = new string[] { "", "" }; if (list != null) { for (int i = 0, j = 0; i < list.Count; i++, j++) { if (list[i][0] == "imgs") { j--; continue; } TreeNode tree1 = new TreeNode() { Text = list[i][0] }; treeS.Add(tree1); loadTree(list[i][1], treeS[j].Nodes); } } return treeS;}
2.点击加载博客内容（这里使用到了webBrowser控件来显示博客内容）
#region 点击tree树 加载对应内容 /// <summary> /// 点击tree树 加载对应内容 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { if (e.Action == TreeViewAction.ByMouse || e.Action == TreeViewAction.ByKeyboard) { htmlPath = FileHelp.PathBlogs + Forward.ForwardPath + e.Node.FullPath; string html = FileHelp.GetFile(htmlPath); HtmlAgilityPack.HtmlDocument docment = new HtmlAgilityPack.HtmlDocument(); docment.LoadHtml(html); try { var text_html = docment.DocumentNode.SelectNodes("//div[@id='my_html_postBody']")[0].InnerHtml; var mytext_url = docment.DocumentNode.SelectNodes("//div[@id='mytext_url']")[0].InnerHtml; webBrowser1.DocumentText = text_html; text_url.Text = mytext_url; } catch (Exception) { } } } #endregion功能三：本地浏览关键字搜索
搜索使用的Lucenne.net。这里面的水太深了。这里就使用到了点皮毛。这里给出一些资料地址。
1.首先在备份的时候就需要创建搜索索引。
/// <summary>/// 创建索引/// </summary>/// <param name="analyzer"></param>/// <param name="title"></param>/// <param name="content"></param>private static void AddIndex(IndexWriter writer, string title, string content, string filePath, string id, string mytext_BlogTitleName = "Blog", string ClickQuantity = "0"){ try { // Field.Store.YES, Field.Index.ANALYZED, Lucene.Net.Documents.Field.TermVector.WITH_POSITIONS_OFFSETS)); Document doc = new Document(); doc.Add(new Field("Title", title, Field.Store.YES, Field.Index.ANALYZED));//存储且索引 //doc.Add(new Field("Content", content, Field.Store.YES, Field.Index.ANALYZED, Lucene.Net.Documents.Field.TermVector.WITH_POSITIONS_OFFSETS));// Field.Store.YES, Field.Index.ANALYZED));//存储且索引 doc.Add(new Field("Content", content, Field.Store.YES, Field.Index.ANALYZED)); doc.Add(new Field("filePath", filePath, Field.Store.YES, Field.Index.NOT_ANALYZED));//存储且索引 doc.Add(new Field("BlogTitleName", mytext_BlogTitleName, Field.Store.YES, Field.Index.NOT_ANALYZED)); doc.Add(new Field("id", id, Field.Store.YES, Field.Index.NOT_ANALYZED)); doc.Add(new Field("ClickQuantity", ClickQuantity, Field.Store.YES, Field.Index.NOT_ANALYZED)); //防止重复索引 writer.DeleteDocuments(new Term("id", id)); //AddTime writer.AddDocument(doc); } catch (FileNotFoundException fnfe) { throw fnfe; } catch (Exception ex) { throw ex; }}
2.点击搜索
#region 点击搜索 private void but_select_Click(object sender, EventArgs e) { new Thread(delegate() { try { lab_meg.Text = "正在搜索....."; var htm = ""; var list = LuceneHelp.SelectData(FileHelp.PathBlogs + "Index\\", txt_select.Text.Trim(), this.lab_meg); var count = 150; if (list.Count >= count) { var mess = MessageBox.Show("搜索结果过多，是否只显示前" + count + "条~", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Asterisk); if (mess == System.Windows.Forms.DialogResult.Yes) { int index = 0; foreach (var item in list) { index++; htm += "<a name='click_load_file' href='#' filePath='" + item.FilePath + "'>" + item.FileName + "</a><br/><div>" + item.Content + "<div><br/><div style='width:100%;text-align:right;'><span style='margin-right:20px;background-color:#e1d2d2'>作者[" + item.BlogTitleName + "] 搜索(" + item.ClickQuantity + ")</span></div><br/><br/>"; if (index >= count) break; } } else foreach (var item in list) { htm += "<a name='click_load_file' href='#' filePath='" + item.FilePath + "'>" + item.FileName + "</a><br/><div>" + item.Content + "<div><br/><div style='width:100%;text-align:right;'><span style='margin-right:20px;background-color:#e1d2d2'>作者[" + item.BlogTitleName + "] 搜索(" + item.ClickQuantity + ")</span></div><br/><br/>"; } } else { foreach (var item in list) { htm += "<a name='click_load_file' href='#' filePath='" + item.FilePath + "'>" + item.FileName + "</a><br/><div>" + item.Content + "<div><br/><div style='width:100%;text-align:right;'><span style='margin-right:20px;background-color:#e1d2d2'>作者[" + item.BlogTitleName + "] 搜索(" + item.ClickQuantity + ")</span></div><br/><br/>"; } } webBrowser1.DocumentText = htm; htmlList = htm; } catch (Exception ex) { //MessageBox.Show(ex.Message); lab_meg.Text = "搜索出错~" + ex.Message; } }).Start(); } #endregion
