c# - RestSharp 更新 AddHandler 方法的使用以使用工厂委托(delegate)

Question

最新版本的 RestSharp v106.6.9 显然做了一些更改，使得 Request 的 AddHandler 方法的重写过时，例如此签名:

[Obsolete("Use the overload that accepts a factory delegate")]
public void AddHandler(IDeserializer deserializer, params string[] contentTypes)

正如它建议使用工厂委托(delegate)表单

public void AddHandler(string contentType, Func<IDeserializer> deserializerFactory)

public void AddHandler(Func<IDeserializer> deserializerFactory, params string[] contentTypes)

任何人都可以向我指出一个实现此功能的示例吗？或者解释如何将我对实现 IDeserializer 的 customSerializer 的使用转换为工厂委托(delegate):

RestClient.AddHandler("application/json", CustomJsonSerializer.Instance);


public class CustomJsonSerializer : IDeserializer
{
    public static CustomJsonSerializer Instance => new CustomJsonSerializer();

    public string ContentType
    {
        get => "application/json";
        set { } // maybe used for Serialization?
    }

    public string DateFormat { get; set; }

    public string Namespace { get; set; }

    public string RootElement { get; set; }

    public T Deserialize<T>(IRestResponse response) => RestSharpResponseHandlers.DeserializeObject<T>(response);
}

根据源代码https://github.com/restsharp/RestSharp/blob/dev/src/RestSharp/RestClient.cs :

 [Obsolete("Use the overload that accepts a factory delegate")]
 public void AddHandler(string contentType, IDeserializer deserializer) =>
    AddHandler(contentType, () => deserializer);

过时的重载仅调用 AddHandler(string contentType, Func<IDeserializer> deserializerFactory)过载。

因此，您可以替换代码以添加自定义处理程序，如下所示:

RestClient.AddHandler("application/json", () => { return CustomJsonSerializer.Instance; });
