RestSharp 更新使用 AddHandler 方法以使用工厂委托

Question

最新版本的 RestSharp v106.6.9 显然做了一些更改，使得 Request 的 AddHandler 方法的覆盖过时，例如这个签名：

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

因为它建议使用工厂委托形式

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

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

谁能给我指出一个实现这个的例子。或者在下面解释如何将我对实现 IDeserializer 的 customSerializer 的使用转换为工厂委托：

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);
}

Answer 1

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

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

过时的重载只是调用 AddHandler(string contentType, Func<IDeserializer> deserializerFactory) 重载。

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; });

我运行陷入同样的问题。看起来 OpenAPI 代码正在为多种上下文类型设置多个处理程序，所以我编写了这个小函数

        private void AddHandlerHelper(RestClient client, IDeserializer deserializerFactory, string[] contextTypes)
        {
            foreach( var contextType in contextTypes)
            client.AddHandler(contextType,() => deserializerFactory);
        }

并且调用从这里更改：

client.AddHandler(() => existingDeserializer, "application/json", "text/json", "text/x-json", "text/javascript", "*+json");

至此

AddHandlerHelper(client, existingDeserializer, new string[] { "application/json", "text/json", "text/x-json", "text/javascript", "*+json"});

生成的代码中有六个地方我需要这个函数。
