c# winform 火狐浏览器 查看cookie

c# winform 火狐浏览器 查看cookie

Firefox的Cookie数据位于：%APPDATA%MozillaFirefoxProfiles 目录中的xxx.default目录，名为cookies.sqlite的文件。
如：C:UsersjayAppDataRoamingMozillaFirefoxProfilesji4grfex.defaultcookies.sqlite
在Firefox中查看cookie, 可以选择”工具 > 选项 >” “隐私 > 显示cookie”。

1、先获取cookies.sqlite文件路径

2、SQLite数据库需要引用System.Data.SQLite
  下载地址：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来查看数据：
  下载地址：http://sourceforge.net/projects/sqlitebrowser/

3、SQLite.Interop.dll文件要复制到输出目录中

4、通过name和host字段查询返回value值，value带有中文要转译
  HttpUtility.UrlDecode需要引用System.Web

好吧，SQLite确实也很强大，只不过在这里并不是很爽，原因是需要以上2个dll文件才可以正常使用。
那下面就用另一种办法实现下，虽然效率没有上面的高，但已足够用了。

首先使用记事本打开cookies.sqlite文件观察
得到格式：
  站点(域名)+Cookie名称+内容+域+路径

实现通过指定名称+域，取中间的部分就是cookie值。
使用正则表达式：
(?<=jd.com_pst)(?'value'[w%]+)(?=.jd.com)
