绝对URL不能与虚拟目录一起使用？

Question

我创建了几个虚拟导演,我希望能够从当前的http请求中获取url.

例如:

http://www.site.com/app_1/default.aspx ===> http://www.site.com/app_1/

http://www.site.com/app_2/default.aspx ===> http://www.site.com/app_2/

....

http://www.site.com/app_n/default.aspx ===> http://www.site.com/app_n/

我的代码:

    string urlApp = HttpContext.Current.Request.Url.AbsoluteUri.ToString();
    urlApp = urlApp.Substring(0, urlApp.LastIndexOf('/') + 1);

我试过

    string urlApp = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + "/";

在localhost中工作得很好:http://localhost:2468/test.aspx结果http://localhost:2468/

,但是当通过虚拟目录访问http://myhost/app_1/test.aspx结果时http://myhost/

我怎么能得到http://myhost/app_1/？

Answer 1

HttpContext.Current.Request.ApplicationPath 

是您获取到虚拟目录的路由所需的.将其附加到您已经获得的网址上,然后您就会成为赢家.就像是

HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + HttpContext.Current.Request.ApplicationPath

应该工作,但要注意拖尾斜线.
