c# - DataContractJsonSerializerOperationFormatter 不反序列化使用 JSON.NET

Question

我正在使用 WCF RESTful 网络服务，但出现此错误:

There was an error while trying to deserialize parameter http://tempuri.org/:aa. The InnerException message was 'There was an error deserializing the object of type WcfService1.Test. DateTime content '2014-05-31T18:30:00.000Z' does not start with '/Date(' and end with ')/' as required for JSON.'. Please see InnerException for more details.'. See server logs for more details. The exception stack trace is:`

at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeParameterPart(XmlDictionaryReader reader, PartInfo part) at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeParameter(XmlDictionaryReader reader, PartInfo part) at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeParameters(XmlDictionaryReader reader, PartInfo[] parts, Object[] parameters, PartInfo returnInfo, Object& returnValue) at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeBodyCore(XmlDictionaryReader reader, Object[] parameters, Boolean isRequest) at

来自 jQuery 的输入:

          $.ajax({
                    url: "Restful.svc/new/one",
                    type: "POST",
                    contentType: "application/json; charset=utf-8",
                    headers: {
                        'Accept': 'application/json',
                        'Content-Type': 'application/json'
                    },
                    data: JSON.stringify({ aa: { xaaaaaa: "2014-05-31T18:30:00.000Z" } }),
                    dataType: 'json',
                    processData: true,
                    success: function (msg) {
                        alert(msg.helloWorldResult);
                    },
                    error: function (msg) {
                        var y = 0;
                    }
                });

WCF 服务:

        [OperationContract]
        [WebInvoke(Method = "POST",
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "new/one")]
        String helloWorld(Test aa);

测试类:

    public class Test
    {
         [JsonProperty(ItemConverterType=typeof(IsoDateTimeConverter))]
         public DateTime xaaaaaa { get; set; }
    }

如果我将输入 xaaaaaa 传递为:/Date(new Date.valueOf().toString())/ 它会接受。如何更改默认值WCF 服务中的日期格式化程序使用 IsoDateFormat 进行序列化和反序列化。

我已尝试修改路由表设置，但无法找到大部分库。如果我使用 JSON.NET，它会说它默认使用 ISO 格式。我如何设置它以在 WCF Web 服务中使用它？

我正在使用 Newtonsoft 序列化日期格式以保存 ISODate 格式。我能够解决我的问题:

测试.cs:

[DataContract]
public class Test
{
    public DateTime xaaaaaa { get; set; }

    [DataMember(Name = "xaaaaaa")]
    private string HiredForSerialization { get; set; }

    [OnSerializing]
    void OnSerializing(StreamingContext ctx)
    {
        this.HiredForSerialization = JsonConvert.SerializeObject(this.xaaaaaa).Replace('"',' ').Trim();
    }

    [OnDeserialized]
    void OnDeserialized(StreamingContext ctx)
    {
        this.xaaaaaa = DateTime.Parse(this.HiredForSerialization);
    }

}

jQuery:

$.ajax({
    url: "Transfer.svc/new/one",
    type: "POST",
    contentType: "application/json; charset=utf-8",
    headers: {
          'Accept': 'application/json',
          'Content-Type': 'application/json'
    },
    data: JSON.stringify({ aa: { xaaaaaa: "2014-05-31T18:30:00.000Z" } }),
    dataType: 'json',
    processData: true,
    success: function (msg) {
    tester = msg.helloWorldResult; //"2014-06-01T00:00:00+05:30"
    },
    error: function (msg) {
    var y = 0;
    }
});

我从日期选择器 (jQuery) 中选择的日期:

WCF 服务看起来像这样:

    [OperationContract]
    [WebInvoke(Method = "POST",
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "new/one")]
    public Test helloWorld(Test aa)
    {
        return aa;
    }

效果很好!
