Request擷取url資訊

在ASP.NET程式設計中經常需要用Request擷取url的有關資訊，Request中有多種方法擷取url資訊

連轉再載再測如下： 

（一）頁面Test.aspx

protected void Page_Load(object sender, EventArgs e)

{

    Response.Write("Request.ApplicationPath：" + Request.ApplicationPath + "<br/>");

    Response.Write("Request.CurrentExecutionFilePath：" + Request.CurrentExecutionFilePath + "<br/>");

    Response.Write("Request.Path：" + Request.Path + "<br/>");

    Response.Write("Request.PathInfo：" + Request.PathInfo + "<br/>");

    Response.Write("Request.PhysicalApplicationPath：" + Request.PhysicalApplicationPath + "<br/>");

    Response.Write("Request.PhysicalPath：" + Request.PhysicalPath + "<br/>");

    Response.Write("Request.RawUrl：" + Request.RawUrl + "<br/>");

    Response.Write("Request.Url.AbsolutePath：" + Request.Url.AbsolutePath + "<br/>");

    Response.Write("Request.Url.AbsoluteUri：" + Request.Url.AbsoluteUri + "<br/>");

    Response.Write("Request.Url.Host：" + Request.Url.Host + "<br/>");

Response.Write("Request.Url.LocalPath：" + Request.Url.LocalPath + "<br/>");

if (Request.UrlReferrer != null)

            Response.Write("上一頁的位址：" + Request.UrlReferrer.AbsolutePath);

//UrlReferrer:擷取有關用戶端上次請求的 URL 的資訊，該請求連結到目前的 URL。

}

（二）頁面a.aspx

在頁面a.aspx中添加對Test.aspx的連結

<a href="Test.aspx" target="_self">點選</a>

（三）通路a.aspx，并點選連結

結果：

Request.ApplicationPath：/web2

Request.CurrentExecutionFilePath：/web2/Test.aspx

Request.Path：/web2/Test.aspx

Request.PathInfo：

Request.PhysicalApplicationPath：E:\test8\Net35\web2\

Request.PhysicalPath：E:\test8\Net35\web2\Test.aspx

Request.RawUrl：/web2/Test.aspx

Request.Url.AbsolutePath：/web2/Test.aspx

Request.Url.AbsoluteUri：http://localhost:20372/web2/Test.aspx

Request.Url.Host：localhost

Request.Url.LocalPath：/web2/Test.aspx

上一頁的位址：/web2/la1.aspx

iframe裡測了一下，沒有變化
