如何在本地计算机上以编程方式访问Google Chrome浏览器历史记录

Question

我想写一个简单的程序,显示我在一段时间内的网络活动(我访问过哪个网站,多少次等等).我大多使用谷歌Chrome浏览器.我发现Chrome会在这个位置存储浏览器历史记录(如果我错了请纠正我)

C:\Documents and Settings\<username>\Local Settings\Application Data\Google\Chrome\User Data\Default

如何打开历史文件？它们没有任何文件扩展名.我无法使用记事本,SQLite浏览器打开.如何以编程方式访问此数据？我想知道它是哪种文件格式以及如何使用C#等编程语言来读取它.

Answer 1

它只是一个SQlite 3数据库,我能够成功打开它(当然你无法打开正在运行的浏览器的锁定数据库).

Answer 2

这是我创建的用于从Google Chrome浏览器中读取浏览数据的课程.我从这里得到的大部分代码,但我调整了它以增加对谷歌浏览器的支持.您可能还想从此处下载.Net的SQLite,并添加对System.Data.Sqlite的引用.

class GoogleChrome
{
    public List<URL> URLs = new List<URL>();
    public IEnumerable<URL> GetHistory()
    {
        // Get Current Users App Data
        string documentsFolder = Environment.GetFolderPath
        (Environment.SpecialFolder.ApplicationData);
        string[] tempstr = documentsFolder.Split('\\');
        string tempstr1 = "";
        documentsFolder += "\\Google\\Chrome\\User Data\\Default";
        if (tempstr[tempstr.Length - 1] != "Local")
        {
            for (int i = 0; i < tempstr.Length - 1; i++)
            {
                tempstr1 += tempstr[i] + "\\";
            }
            documentsFolder =  tempstr1 + "Local\\Google\\Chrome\\User Data\\Default";
        }


        // Check if directory exists
        if (Directory.Exists(documentsFolder))
        {
            return ExtractUserHistory(documentsFolder);

        }
        return null;
    }


    IEnumerable<URL> ExtractUserHistory(string folder)
    {
        // Get User history info
        DataTable historyDT = ExtractFromTable("urls", folder);

        // Get visit Time/Data info
        DataTable visitsDT = ExtractFromTable("visits",
        folder);

        // Loop each history entry
        foreach (DataRow row in historyDT.Rows)
        {

                // Obtain URL and Title strings
                string url = row["url"].ToString();
                string title = row["title"].ToString();

                // Create new Entry
                URL u = new URL(url.Replace('\'', ' '),
                title.Replace('\'', ' '),
                "Google Chrome");

                // Add entry to list
                URLs.Add(u);
        }
        // Clear URL History
        DeleteFromTable("urls", folder);
        DeleteFromTable("visits", folder);

        return URLs;
    }
    void DeleteFromTable(string table, string folder)
    {
        SQLiteConnection sql_con;
        SQLiteCommand sql_cmd;

        // FireFox database file
        string dbPath = folder + "\\History";

        // If file exists
        if (File.Exists(dbPath))
        {
            // Data connection
            sql_con = new SQLiteConnection("Data Source=" + dbPath +
            ";Version=3;New=False;Compress=True;");

            // Open the Conn
            sql_con.Open();

            // Delete Query
            string CommandText = "delete from " + table;

            // Create command
            sql_cmd = new SQLiteCommand(CommandText, sql_con);

            sql_cmd.ExecuteNonQuery();

            // Clean up
            sql_con.Close();
        }
    }

    DataTable ExtractFromTable(string table, string folder)
    {
        SQLiteConnection sql_con;
        SQLiteCommand sql_cmd;
        SQLiteDataAdapter DB;
        DataTable DT = new DataTable();

        // FireFox database file
        string dbPath = folder + "\\History";

        // If file exists
        if (File.Exists(dbPath))
        {
            // Data connection
            sql_con = new SQLiteConnection("Data Source=" + dbPath +
            ";Version=3;New=False;Compress=True;");

            // Open the Connection
            sql_con.Open();
            sql_cmd = sql_con.CreateCommand();

            // Select Query
            string CommandText = "select * from " + table;

            // Populate Data Table
            DB = new SQLiteDataAdapter(CommandText, sql_con);
            DB.Fill(DT);

            // Clean up
            sql_con.Close();
        }
        return DT;
    }
}

URL的类:

class URL
{
    string url;
    string title;
    string browser;
    public URL(string url, string title, string browser)
    {
        this.url = url;
        this.title = title;
        this.browser = browser;
    }

    public string getData()
    {
        return browser + " - " + title + " - " + url;
    }
}

它对我来说就像一个魅力.希望能帮助到你

为了查看sqlite数据库(这是Chromium历史索引),我更喜欢sqlitebrowser.它是免费的,适用于Windows,Mac和Linux.这对我来说是最好的.
