asp.net 获得域名,端口,虚拟目录
记性不好,好多次都被路径问题给拦住了.我现在想得到一个资源的全URL路径,因此首先想得到网站当前的域名,端口和虚拟目录.看下表
底下這張表就是各種跟 Browser Request 的網址相關的屬性與用法：
| 網址：http://localhost:1897/News/Press/Content.aspx/123?id=1#toc | |
| Request.ApplicationPath | / |
| Request.PhysicalPath | D:ProjectsSolutionwebNewsPressContent.aspx |
| System.IO.Path.GetDirectoryName(Request.PhysicalPath) | D:ProjectsSolutionwebNewsPress |
| Request.PhysicalApplicationPath | D:ProjectsSolutionweb |
| System.IO.Path.GetFileName(Request.PhysicalPath) | Content.aspx |
| Request.CurrentExecutionFilePath | /News/Press/Content.aspx |
| Request.FilePath | /News/Press/Content.aspx |
| Request.Path | /News/Press/Content.aspx/123 |
| Request.RawUrl | /News/Press/Content.aspx/123?id=1 |
| Request.Url.AbsolutePath | /News/Press/Content.aspx/123 |
| Request.Url.AbsoluteUri | http://localhost:1897/News/Press/Content.aspx/123?id=1 |
| Request.Url.Scheme | http |
| Request.Url.Host | localhost |
| Request.Url.Port | 1897 |
| Request.Url.Authority | localhost:1897 |
| Request.Url.LocalPath | /News/Press/Content.aspx/123 |
| Request.PathInfo | /123 |
| Request.Url.PathAndQuery | /News/Press/Content.aspx/123?id=1 |
| Request.Url.Query | ?id=1 |
| Request.Url.Fragment | |
| Request.Url.Segments | / News/ Press/ Content.aspx/ 123 |
这里并没有得到域名的方法.还是只好拆分字符串了,我是这么做的:
protected string GetBaseUrl()
{
return Request.Url.AbsoluteUri.Substring(0, Request.Url.AbsoluteUri.IndexOf(Request.RawUrl));
}
var fullImgUrl = GetBaseUrl() + "/Views/Images.ashx?id=" + map;
不知是否有更好的方法得到?
