示例1: ValidateVirtualPathInternal
private void ValidateVirtualPathInternal(VirtualPath virtualPath, bool allowCrossApp, bool codeFile) {
if (!allowCrossApp) {
virtualPath.FailIfNotWithinAppRoot();
}
else {
// If cross app is allowed, and the path is in a different app, nothing more to check
if (!virtualPath.IsWithinAppRoot)
return;
}
//
// Now, detect if it's under a special directory (e.g. 'code', 'resources', 'themes')
//
// If it's exactly the app root, it's fine
if (HttpRuntime.AppDomainAppVirtualPathObject == virtualPath)
return;
int appPathLen = HttpRuntime.AppDomainAppVirtualPathString.Length;
string virtualPathString = virtualPath.VirtualPathString;
// This could happen if the vpath is "/app" (while the app vpath is "/app/")
if (virtualPathString.Length < appPathLen)
return;
// If no slash after the approot (e.g. "/app/foo.aspx"), it's valid
int slashIndex = virtualPathString.IndexOf('/', appPathLen);
if (slashIndex < 0)
return;
// Get the name of the first directory under the app root (e.g. "/app/aaa/bbb/foo.aspx" -> "aaa")
string dir = virtualPathString.Substring(appPathLen, slashIndex - appPathLen);
// If it's a forbidden directory, fail
if (_forbiddenTopLevelDirectories.Contains(dir)) {
throw new HttpException(SR.GetString(SR.Illegal_special_dir, virtualPathString, dir));
}
