c# - 使用 Flurl 从 JSON 解析为对象

Question

我正在使用 Flurl 从 TVDB API 获取 JSON 响应。

我有这门课(现在很笨，只是想获得系列名称):

public class Show
{
    public string seriesName;
}

我是这样使用 Flurl 的:

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

我猜它没有将 JSON 正确映射到对象，因为 JSON 中的“数据”键或者它可能无法将它直接解析为 List<> ？我不确定如何映射它。我想要的结果是 List<Show>与 Show包含seriesName = "Battlestar Galactica: Blood & Chrome" , seriesName = "Battlestar Galactica (2003)"等等等等

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 不是数据数组，它有一个名为 data 的属性，即数组。这意味着您要反序列化的对象不太正确。你应该试试这个:

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>();
