如何在POST请求上使用json.net进行asp.net核心模型绑定？

[HttpPost]
public IActionResult MyAction([FromBody] MyModel model)
{
    // 在这里使用绑定后的模型对象进行处理
    // ...
}

public class JsonModelBinder : IModelBinder
{
    public Task BindModelAsync(ModelBindingContext bindingContext)
    {
        if (bindingContext == null)
        {
            throw new ArgumentNullException(nameof(bindingContext));
        }

        var request = bindingContext.HttpContext.Request;
        using (var reader = new StreamReader(request.Body))
        {
            var body = reader.ReadToEnd();
            var model = JsonConvert.DeserializeObject(body, bindingContext.ModelType);
            bindingContext.Result = ModelBindingResult.Success(model);
        }

        return Task.CompletedTask;
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers(options =>
    {
        options.ModelBinderProviders.Insert(0, new BinderTypeModelBinderProvider(typeof(JsonModelBinder)));
    });
}
