Route、RouteDate 与 RouteTable

RouteDate

 通过路由解析得到的路由数据

public class RouteData
{
    public IDictionary<string, object> Values { get; private set; }

    public IDictionary<string, object> DataTokens { get; private set; }

    public IRouteHandler RouteHandler { get; set; }

    public RouteBase Route { get; set; }

    public RouteData()
    {
        this.Values = new Dictionary<string, object>();
        this.DataTokens = new Dictionary<string, object>();
        this.DataTokens.Add("namespaces", new List<string>());
    }

    public string Controller
    {
        get
            {
                object controllerName = string.Empty;
                this.Values.TryGetValue("controller", out controllerName);
                return controllerName.ToString();
            }
     }

    public string ActionName
    {
        get
        {
            object actionName = string.Empty;
            this.Values.TryGetValue("action", out actionName);
            return actionName.ToString();
        }
    }
}

Route

 路由对象或者叫路由模板

 public class Route : RouteBase
{
    public IRouteHandler RouteHandler { get; set; }

    public string Url { get; set; }

    public IDictionary<string, object> DataTokens { get; set; }

    public Route()
    {
        this.DataTokens = new Dictionary<string, object>();
        this.RouteHandler = new MvcRouteHandler();
    }

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        IDictionary<string, object> variables;
        if (this.Match(httpContext.Request.AppRelativeCurrentExecutionFilePath.Substring(2), out variables))
        {
            RouteData routeData = new RouteData();
            foreach (var item in variables)
            {
                routeData.Values.Add(item.Key, item.Value);
            }
            foreach (var item in DataTokens)
            {
                routeData.DataTokens.Add(item.Key, item.Value);
                routeData.RouteHandler = this.RouteHandler;
                return routeData;
            }
        }
        return null;
    }

    public bool Match(string requestUrl, out IDictionary<string, object> variables)
    {
        variables = new Dictionary<string, object>();
        string[] strArray1 = requestUrl.Split('/');
        string[] strArray2 = this.Url.Split('/');

        if (strArray1.Length!=strArray2.Length)
        {
            return false;
        }
        for (int index = 0; index < strArray2.Length; index++)
        {
            if (strArray2[index].StartsWith("{") && strArray2[index].EndsWith("}"))
            {
                variables.Add(strArray2[index].Trim("{ }".ToArray()), strArray1[index]);
            }
            else
            {
                if (string.Compare(strArray1[index], strArray2[index], true) != 0)
                {
                    return false;
                }
            }
        }
        return true;
    }
}

RouteTable

 多个路由对象组成路由表

public class RouteTable
{
    public static RouteDictionary Routes { get; private set; }

    static RouteTable()
    {
        Routes = new RouteDictionary();
    }
}
