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）
*/
function get_http_referer(ishost) {
if (ishost === undefined) { ishost = true; }
if (document.referrer) {
return document.referrer;
} else {
if (ishost) {
return window.location.protocol + "//" + window.location.host;
} else {
return "";
}
}
}
2. C#
/// <summary>
/// 获取HTTP请求的Referer
/// </summary>
/// <param name="ishost">Referer为空时是否返回Host（网站首页地址）</param>
/// <returns>string</returns>
public string GetReferer(bool ishost)
{
if ( Request.UrlReferrer != null)
{
return Request.UrlReferrer.ToString();
}
else
{
if (ishost)
{
return Request.Url.Scheme + "://" + Request.Url.Authority;
}
else
{
return "";
}
}
}
3. C#中取得Request URL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
