点击超链接从VSTF、SVN及文件共享服务器上下载文件

最近实现一个公司的需求, 不同部门的产品文档路径放在不同地址、不同种类的服务器上, 草草做完一版, 发现文档路径中还有文件共享路径(\\192.168.0.0类型)、还有svn(http://192.168.0.0类型)、还有VSTF路径($/Document/ss....), 各种坑啊, 领导们说起来都很轻松哈, 这样那样就行..... 这个应该不难吧....  都懒得跟他们解释, 爱咋咋吧

言归正传, 文档路径是放在不同类型的服务器上, 目标是一点击文档的链接就能直接下载文件, 还是所有的人都可以下载, 还不能影响用户的原有权限.开始想的简单了, 后来发现这东西头疼啊.

思路:

对于VSTF文件: 当点击的时候文档连接的时候, 通过VSTF的提供的工具, 将代码及Sql脚本获取到固定地址的文件夹, 该文件夹需要发布为网站且能够通过浏览器直接访问文件.

对于SVN文件: 可以通过HTTP访问, 但是涉及到权限问题, 需要给请求附加临时的账户信息, 这里没有考虑修改Cookie信息, 这会是用户的权限变成临时账户. 实现方法就是由WebServer发起请求, 附加账户信息, 将获得的信息返回给客户端浏览器.

对于文件共享: 为了达到练习的效果, 使用了WMI方式和CMD.exe两种方式.

总体思路: 就是返回给客户端的超链接为xxx/WebRequestHandler?url=, 一般处理程序接收到请求后, 更具请求类型、地址类型做相应处理.

领导催促的比较急, 所以好多地方都直接偷懒了, 没有封装, 想的是下回搞TD的时候在整理下吧

具体代码如下:
