使用JavaScript和C#中获得referer
1.JavaScript
/**
*获取HTTP请求的Referer
*@ishost布尔类型Referer为空时是否返回Host（网站首页地址）
*/
functionget_http_referer(ishost){
if(ishost===undefined){ishost=true;}
if(document.referrer){
returndocument.referrer;
}else{
if(ishost){
returnwindow.location.protocol+"//"+window.location.host;
}else{
return"";
}
}
}
2.C#
///<summary>
///获取HTTP请求的Referer
///</summary>
///<paramname="ishost">Referer为空时是否返回Host（网站首页地址）</param>
///<returns>string</returns>
publicstringGetReferer(boolishost)
{
if(Request.UrlReferrer!=null)
{
return Request.UrlReferrer.ToString();
}
else
{
if(ishost)
{
returnRequest.Url.Scheme+"://"+Request.Url.Authority;
}
else
{
return"";
}
}
}
3.C#中取得RequestURL的各个部分
网址：http://localhost:1897/News/Press/Content.aspx/123?id=1#toc
Request.ApplicationPath / Request.PhysicalPath D:\Projects\Solution\web\News\Press\Content.aspx System.IO.Path.GetDirectoryName(Request.PhysicalPath) D:\Projects\Solution\web\News\Press Request.PhysicalApplicationPath D:\Projects\Solution\web\ 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
