ASP.NET 虚拟路径在哪里解析波浪号~
在链接中,例如
<link rel="stylesheet" type="text/css" href="~/Css/Site.css" />
它是否重定向,或者RedirectToAction
在 ASP.NET MVC 中?
它从这里获取:
VirtualPathUtility.ToAbsolute(contentPath, httpContext.Request.ApplicationPath);
这是反射器输出PathHelpers
上课于系统.Web.Mvc DLL:
private static string GenerateClientUrlInternal(HttpContextBase httpContext, string contentPath)
{
if (string.IsNullOrEmpty(contentPath))
{
return contentPath;
}
if (contentPath[0] == '~')
{
string virtualPath = VirtualPathUtility.ToAbsolute(contentPath, httpContext.Request.ApplicationPath);
string str2 = httpContext.Response.ApplyAppPathModifier(virtualPath);
return GenerateClientUrlInternal(httpContext, str2);
}
NameValueCollection serverVariables = httpContext.Request.ServerVariables;
if ((serverVariables == null) || (serverVariables["HTTP_X_ORIGINAL_URL"] == null))
{
return contentPath;
}
string relativePath = MakeRelative(httpContext.Request.Path, contentPath);
return MakeAbsolute(httpContext.Request.RawUrl, relativePath);
}
