博客备份小工具3

    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 + "" + "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"
                        });

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
