使用Flurl将JSON解析为对象

7

我正在使用Flurl从TVDB API获取JSON响应。

我有这个类（现在是简化的，只是尝试获得seriesNames）：

public class Show
{
    public string seriesName;
}

我正在这样使用Flurl：

dynamic test = await "https://api.thetvdb.com/search/series?name=battlestar"
            .WithHeader("Accept", "application/json")
            .WithHeader("Authorization", " Bearer " + token.token)                
            .GetAsync()                
            .ReceiveJson<List<Show>>();

我猜测它不能将JSON正确地映射到对象中，可能是由于JSON中的"data"键或者它不能直接解析为一个List<>。我不确定如何映射这个数据。我想要的结果应该是一个List<Show>，其中包含Show，其seriesName = "Battlestar Galactica: Blood & Chrome"，seriesName = "Battlestar Galactica (2003)"等等。

  "data": [
    {

Ensign William Adama (Pasqualino), barely in his 20's and a recent Academy graduate, finds himself assigned to one of the most powerful ships in the Colonial fleet...the Galactica. The talented but hot-headed risk-taker soon finds himself leading a dangerous top secret mission that, if successful, will turn the tide of the decade-long war in favor of the desperate fleet.",

编辑：这是在ex.Message中：

Request to https://api.thetvdb.com/search/series?name=battlestar failed. Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[TVDBapi.ShowData]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

您发布的 JSON 不是一个数据数组，它有一个名为 data 的属性，该属性才是数组。这意味着您反序列化的对象不完全正确。您应该尝试使用以下代码：

public class ShowData
{
    public List<Show> data { get; set; }
}

public class Show
{
    public string[] aliases { get; set; }
    public string banner { get; set; }
    public string firstAired { get; set; }
    public int id { get; set; }
    public string network { get; set; }
    public string overview { get; set; }
    public string seriesName { get; set; }
    public string status { get; set; }
}

然后像这样反序列化：

....ReceiveJson<ShowData>();
