數字和大小寫字母都ok,但是中文地址就會有問題
public bool IslocalURL(string url)
{
if (string.IsNullOrEmpty(url))
{
return false;
}
Uri absoluteUri;
if (Uri.TryCreate(url, UriKind.Absolute, out absoluteUri))
{
return String.Equals(this._httpContext.Request.Url.Host, absoluteUri.Host, StringComparison.OrdinalIgnoreCase);
}
else
{
bool isLocal = !url.StartsWith("http:", StringComparison.OrdinalIgnoreCase)
&& !url.StartsWith("https:", StringComparison.OrdinalIgnoreCase)
&& Uri.IsWellFormedUriString(url, UriKind.Relative);
return isLocal;
}
}
解決辦法:
利用 Uri.EscapeUriString(String) Method
Converts a URI string to its escaped representation.
public static string EscapeUriString (string stringToEscape);
.
//解决中文url 不会触发301
pageUrl = Uri.EscapeUriString(pageUrl); //301 (permanent) redirection
if (webHelper.IslocalURL(pageUrl))
{
filterContext.Result = new RedirectResult(pageUrl, true);
}
