读取Chrome书签文件

使用C#读取Chrome浏览器的本地书签文件，当前文件在C盘下用户文件夹AppDataLocalGoogleChromeUser DataDefault下的Bookmarks

打开这个文件我们发现就是一个json文本文件

{
   "checksum": "e723a57c9d9cbcae27ce0e1f8a5b7e71",
   "roots": {
      "bookmark_bar": {
         "children": [ {
            "date_added": "13157449994873867",
            "id": "5",
            "meta_info": {
               "last_visited_desktop": "13157449994874078"
            },
            "name": "微软 Bing 搜索 - 国内版",
            "type": "url",
            "url": "https://cn.bing.com/"
         } ],
         "date_added": "13157449956838246",
         "date_modified": "13157449994873867",
         "id": "1",
         "name": "书签栏",
         "type": "folder"
      },
      "other": {
         "children": [  ],
         "date_added": "13157449956838251",
         "date_modified": "0",
         "id": "2",
         "name": "其他书签",
         "type": "folder"
      },
      "synced": {
         "children": [  ],
         "date_added": "13157449956838253",
         "date_modified": "0",
         "id": "3",
         "name": "移动设备书签",
         "type": "folder"
      }
   },
   "version": 1
}

为了方便读取操作还是将json字符串转换为对象这里分析json结构创建对应的对象

namespace DataOperation.Model
{
    /// <summary>
    /// Chorme书签保存文件结构
    /// </summary>
    public class ChromeBookmarks
    {
        public string checksum { get; set; }
        public bookmark roots { get; set; }
        //public  string sync_transaction_version { get; set; }
        public string version { get; set; }
        //public  string synced { get; set; }
    }

    public class bookmark
    {
        public datameta bookmark_bar { get; set; }
        public datameta other { get; set; }
    }
    
    public class datameta
    {
        public List<datameta> children { get; set; }
        public  string date_added { get; set; }
        public  string date_modified { get; set; }
        public  string id { get; set; }
        public meta_info meta_info { get; set; }
        public  string name { get; set; }
        public  string sync_transaction_version { get; set; }
        public  string type { get; set; }
        public  string url { get; set; }
    }

    public class meta_info
    {
        public string last_visited_desktop { get; set; }
    }
}

利用.NET提供的Newtonsoft.Json.dll来进行转换这里预先封装两个方法

        /// <summary>
        /// json序列化
        /// </summary>
        /// <typeparam name="T">数据类型</typeparam>
        /// <param name="data">数据</param>
        /// <returns></returns>
        public static string ListToJson<T>(T data)
        {
            string str = string.Empty;
            try
            {
                if (null != data)
                    str = JsonConvert.SerializeObject(data);
            }
            catch (Exception e)
            {

            }
            return str;
        }

        /// <summary>
        /// 反序列化
        /// </summary>
        /// <typeparam name="T">数据类型</typeparam>
        /// <param name="jsonstr">数据</param>
        /// <returns></returns>
        public static Object JsonToList<T>(string jsonstr)
        {
            Object obj = null;
            try
            {
                if (null != jsonstr)
                    obj = JsonConvert.DeserializeObject<T>(jsonstr);//反序列化
            }
            catch (Exception e)
            {

            }
            return obj;
        }

剩下的就是将Bookmarks文本文件读取后进行转换了

下面部分代码

        /// <summary>
        /// 读取文件
        /// </summary>
        /// <param name="filePath"></param>
        /// <returns></returns>
        public static string FileRead(string filePath)
        {
            string rel = File.ReadAllText(filePath);
            return rel;
        }    

        /// <summary>
        /// 获取Chrome浏览器书签对象
        /// </summary>
        /// <param name="filePath"></param>
        /// <returns></returns>
        public ChromeBookmarks GetChromeBookmarksData(string filePath)
        {
            string str = FileRead(filePath);
            object chromeBookmarks = JsonToList<ChromeBookmarks>(str);
            if (chromeBookmarks != null)
            {
                return (ChromeBookmarks)chromeBookmarks;
            }
            return null;
        }
