解決中文地址Uri.IsWellFormedUriString返回false

 

數字和大小寫字母都ok,可是中文地址就會有問題web

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:api

利用 Uri.EscapeUriString(String) Methodthis

Converts a URI string to its escaped representation.url

public static string EscapeUriString (string stringToEscape);

.spa

  //解決中文url 不會觸發301
            pageUrl = Uri.EscapeUriString(pageUrl);

            //301 (permanent) redirection 
            if (webHelper.IslocalURL(pageUrl))
            {
                filterContext.Result = new RedirectResult(pageUrl, true);
            }
