Asp.net web api Swashback和MediaTypeFormatter出现问题

我正在尝试在我的WebApi上应用Swashback。在大多数情况下，它是有效的

对于某些Api端点，对于

GET

，方法接受来自查询字符串的

JSON

作为参数。为了将数据从

JSON

转换为.NET对象，这里有一些

MediaTypeFormatter

。

MediaTypeFormatter

s通常如下所示：

public class MyMediaTypeFormatter : JsonMediaTypeFormatter
{
    public override bool CanReadType(Type type)
    {
        return type == typeof (MyType);
    }

    public override bool CanWriteType(Type type)
    {
        return false;
    }

    public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger,
        CancellationToken cancellationToken)
    {
        //Do deserialization here
    }
}

---

我需要为此指定任何显式配置吗？

据我所见，我猜Swashback将该参数解释为主体参数而不是查询参数。你能分享一个

GET

方法吗？@venerik谢谢你的评论。我现在无法访问我的系统。因此，很难共享

GET

请求。然而，方法参数是一个相对复杂的对象图，例如，一个包含不同类型对象数组的对象等等。
