.Net 4.0 上的 ServiceStack.Text JSON 解析

发布于 2024-10-11 07:27:30 字数 904 浏览 3 评论 0原文

H 伙计们，我正在尝试使用 ServiceStack.Text 进行 JSON 解析（在我见过的各种基准测试中，它的性能似乎比 JSON.Net 更好）。但我没有得到我期望的结果。我试图反序列化的类看起来像这样：

[DataContract]
public class RpcRequest<T>
{
    [JsonProperty("id")]
    [DataMember(Name="id")]
    public String Id;

    [JsonProperty("method")]
    [DataMember(Name="method")]
    public String Method;

    [JsonProperty("params")]
    [DataMember(Name="params")]
    public T Params;

    [JsonIgnore]
    [IgnoreDataMember]
    public Policy Policy;
}

我正在像这样调用解析器

public static class Json
{
    public static T Deserialize<T>(string serialized)
    {
        return TypeSerializer.DeserializeFromString<T>(serialized);
    }
}
...
RpcRequest<Params> myRequeset = Json.Deserialize(packet);

但是我从该调用中返回一个没有设置任何值的实例。即Id、Method和Params都为null。我是否正确使用了这个 API？

H chaps,
I am trying to use ServiceStack.Text for JSON parsing (it seems to be performing better than JSON.Net in various benchmarks I have seen). But I am not getting the results I am expecting. The class I am attempting to deserialize looks like this:

[DataContract]
public class RpcRequest<T>
{
    [JsonProperty("id")]
    [DataMember(Name="id")]
    public String Id;

    [JsonProperty("method")]
    [DataMember(Name="method")]
    public String Method;

    [JsonProperty("params")]
    [DataMember(Name="params")]
    public T Params;

    [JsonIgnore]
    [IgnoreDataMember]
    public Policy Policy;
}

And I am invoking the parser like this

public static class Json
{
    public static T Deserialize<T>(string serialized)
    {
        return TypeSerializer.DeserializeFromString<T>(serialized);
    }
}
...
RpcRequest<Params> myRequeset = Json.Deserialize(packet);

However I am getting an instance back from that call which has none of the values set. ie Id, Method and Params are all null. Am I using this API correctly?

看来ServiceStack不支持公共字段，只支持公共属性。因此，如果我将模型对象更改为以下内容，一切都会正常。

[DataContract]
public class RpcRequest<T>
{
    [JsonProperty("id")]
    [DataMember(Name="id")]
    public String Id { get; set; }

    [JsonProperty("method")]
    [DataMember(Name="method")]
    public String Method { get; set; }

    [JsonProperty("params")]
    [DataMember(Name="params")]
    public T Params { get; set; }

    [JsonIgnore]
    [IgnoreDataMember]
    public Policy Policy { get; set; }
}

请注意为每个属性添加了 getter 和 setter。

It seems that ServiceStack does not support public fields, only public properties. So if I change my model object to the following it all works.

[DataContract]
public class RpcRequest<T>
{
    [JsonProperty("id")]
    [DataMember(Name="id")]
    public String Id { get; set; }

    [JsonProperty("method")]
    [DataMember(Name="method")]
    public String Method { get; set; }

    [JsonProperty("params")]
    [DataMember(Name="params")]
    public T Params { get; set; }

    [JsonIgnore]
    [IgnoreDataMember]
    public Policy Policy { get; set; }
}

Note the addition of getters and setters to each property.
