删除尾随斜杠-不使用IIS重写ASP.net

如果不使用IIS重写模块，如何删除尾部斜杠？

我想我可以在global.asax.cs文件中向RegisterRoutes函数添加一些内容吗？

删除尾随斜杠-不使用IIS重写ASP.net

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        // Do Not Allow URL to end in trailing slash
        string url = HttpContext.Current.Request.Url.AbsolutePath;
        if (string.IsNullOrEmpty(url)) return;
        string lastChar = url[url.Length-1].ToString();
        if (lastChar == "/" || lastChar == "''")
        {
            url = url.Substring(0, url.Length - 1);
            Response.Clear();
            Response.Status = "301 Moved Permanently";
            Response.AddHeader("Location", url);
            Response.End();
        }
    }

在HttpContext.Current.Request上使用扩展方法使其可用于其他类似问题，例如重定向以避免页面1:的重复内容URL

public static class HttpRequestExtensions
{
    public static String RemoveTrailingChars(this HttpRequest request, int charsToRemove)
    {
        // Reconstruct the url including any query string parameters
        String url = (request.Url.Scheme + "://" + request.Url.Authority + request.Url.AbsolutePath);
        return (url.Length > charsToRemove ? url.Substring(0, url.Length - charsToRemove) : url) + request.Url.Query;
    }
}

这可以根据需要调用：

protected void Application_BeginRequest(Object sender, EventArgs e)
{
    String requestedUrl = HttpContext.Current.Request.Url.AbsolutePath;
    // If url ends with /1 we're a page 1, and don't need (shouldn't have) the page number
    if (requestedUrl.EndsWith("/1"))
        Response.RedirectPermanent(Request.RemoveTrailingChars(2));
    // If url ends with / redirect to the URL without the /
    if (requestedUrl.EndsWith("/") && requestedUrl.Length > 1)
        Response.RedirectPermanent(Request.RemoveTrailingChars(1));
}
