将List <object>转换为NancyFx响应</object>

Question

我正在尝试使用LinqToQuerystring构建一个Nancy OData支持应用程序。我得到了以下示例代码。它适用于任何查询网址：

http：/ test /？$ filter =推荐eq true

获取[“/ test”] = _ =＆gt;

{                     var dict =（IDictionary）Request.Query.ToDictionary（）;

                new List<Movie>
                 {
                     new Movie
                  {
                  Title = "Matrix (The)",
                  ReleaseDate = new DateTime(1999, 3, 31),
                  DurationInMinutes = 136,                    
                  MetaScore = 73,
                  Director = "Wachowski Brothers",
                  Recommended = true
                  },
                 new Movie
               {
               Title = "There and Back Again, An Unexpected Journey",
               ReleaseDate = new DateTime(2012, 12, 14),
               DurationInMinutes = 169,
               MetaScore = 58,
               Director = "Peter Jackson",
               Recommended = false
               }
              }.AsQueryable() 
                 .LinqToQuerystring(dict);
               return dict;
     }

Answer 1

您可以先调用ToDictionary解决此问题。

即

var dict = (IDictionary<string, object>) Request.Query.ToDictionary();
...
.LinqToQuerystring(dict);

这可能是因为LinqToQuerystring处理字典的方式，在中间窗口输出它们导致：

(IDictionary<string, object>) Request.Query
{Nancy.DynamicDictionary}
    [Nancy.DynamicDictionary]: {Nancy.DynamicDictionary}
    Keys: Count = 2
    Values: Count = 2

(IDictionary<string, object>) Request.Query.ToDictionary()
Count = 2
    [0]: {[one, one]}
    [1]: {[two, 2]}

修改

根据您的评论，我假设您希望始终返回JSON。

如果是这样的话，你会这样做就是返回：

return Response.AsJson(dict);

这会将字典序列化为JSON。
