c# winform 火狐瀏覽器 查看cookie

Firefox的Cookie數據位於：%APPDATA%\Mozilla\Firefox\Profiles\ 目錄中的xxx.default目錄，名為cookies.sqlite的文件。
如：C:\Users\jay\AppData\Roaming\Mozilla\Firefox\Profiles\ji4grfex.default\cookies.sqlite
在Firefox中查看cookie, 可以選擇”工具 > 選項 >” “隱私 > 顯示cookie”。

1、先獲取cookies.sqlite文件路徑

2、SQLite數據庫需要引用System.Data.SQLite
  下載地址：http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
  得到System.Data.SQLite.dll添加到工程引用；

*可以使用SQLite Database Browser來查看數據：
  下載地址：http://sourceforge.net/projects/sqlitebrowser/

3、SQLite.Interop.dll文件要復制到輸出目錄中

4、通過name和host字段查詢返回value值，value帶有中文要轉譯
  HttpUtility.UrlDecode需要引用System.Web

好吧，SQLite確實也很強大，只不過在這里並不是很爽，原因是需要以上2個dll文件才可以正常使用。
那下面就用另一種辦法實現下，雖然效率沒有上面的高，但已足夠用了。

首先使用記事本打開cookies.sqlite文件觀察
得到格式：
  站點(域名)+Cookie名稱+內容+域+路徑

實現通過指定名稱+域，取中間的部分就是cookie值。
使用正則表達式：
(?<=jd.com_pst)(?'value'[\w%]+)(?=.jd.com)
