任何人有任何的REST風格的URL的一個例子在ASP.NET MVC 2 RC的作品？

Question

我在這裏試圖代碼：

http://dotnetslackers.com/articles/aspnet/Implementing-RESTful-Routes-and-Controllers-in-ASP-NET-MVC-2-0.aspx#s-reststyle-routes--controllers

但我就是不能讓這與ASP.NET MVC 2.0 RC工作 - PUT和DELETE動詞沒有得到使用。輸出似乎是正確的，但路由處理程序似乎忽略HttpMethodOverride。

我禁用默認路由，現在當我嘗試提交表單設置爲PUT，錯誤的覆蓋「用於訪問路徑的HTTP動詞POST‘/聯繫人/ 2’是不允許的。」即將到來。所以它似乎忽略了MethodOverride。

Answer 1

我發現了原因 - HttpMethodConstraint沒有檢查X-HTTP-Method-Override字段，因此，例如在該文章中，HttpMethodConstraint被設置爲只允許「PUT」，但是couurse「POST」被HttpContext返回，所以失敗了。

我寫我自己RouteConstraint，並張貼在這裏，以便其他人可以從我的麻煩學習。

public class HttpVerbConstraint : IRouteConstraint { 

    public HttpVerbConstraint(params string[] allowedMethods) { 
     if (allowedMethods == null) { 
      throw new ArgumentNullException("allowedMethods"); 
     } 
     this.AllowedMethods = allowedMethods.ToList<string>().AsReadOnly(); 
    } 

    protected virtual bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { 
     if (httpContext == null) { 
      throw new ArgumentNullException("httpContext"); 
     } 
     if (route == null) { 
      throw new ArgumentNullException("route"); 
     } 
     if (parameterName == null) { 
      throw new ArgumentNullException("parameterName"); 
     } 
     if (values == null) { 
      throw new ArgumentNullException("values"); 
     } 

     string method = httpContext.Request["X-HTTP-Method-Override"] ?? httpContext.Request.HttpMethod; 

     switch (routeDirection) { 
      case RouteDirection.IncomingRequest: 
       return AllowedMethods.Any(v => 
       v.Equals(method, StringComparison.OrdinalIgnoreCase)); 
      case RouteDirection.UrlGeneration: 
       string verb = "GET"; 
       if (values.ContainsKey(parameterName)) 
        verb = values[parameterName].ToString(); 
       return AllowedMethods.Any(v => 
        v.Equals(verb, StringComparison.OrdinalIgnoreCase)); 
     } 
     return true; 
    } 

    bool IRouteConstraint.Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { 
     return this.Match(httpContext, route, parameterName, values, routeDirection); 
    } 

    public ICollection<string> AllowedMethods { get; set; } 

}
