在WCF

Question

所以我使用WCF服务在数据库中插入数据，为此我将POST中的数据发送到我的WCF服务并使用DataContract收集它：

POST发送的JSON数据

{ "data": { "subsidiarySid":"0", "storesid":"0", "date":"2018-06-15", "counters": [ { "nation":"France", "count":"5" }, { "nation":"France", "count":"5" } ] } }

DataContract

[DataContract(Name ="data")]
    public class Count
    {
    [DataMember(Name ="subsidiarySid")]
    public string subsidiarySid;

    [DataMember(Name ="storeSid")]
    public string storeSid;

    [DataMember(Name = "date")]
    public string date;

    [DataMember(Name = "counters")]
    public IEnumerable<Counter> counters;
}

[DataContract]
public class Counter
{
    [DataMember(Name = "nationalitySid")]
    public string nationalitySid;

    [DataMember(Name = "count")]
    public string count;
}

界面中的方法

[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "count_customers")]
string PostCount(Count count);

问题是当我尝试访问此对象时，我得到一个null ... 我的合同是错的还是我在其他地方乱了？ 我也可以在json的开头摆脱“data {}”（就像havig直接在json的根目录下我的“subsidiarySid等”）？

Answer 1

毕竟找到了我的方式，所以我发布它作为答案供将来参考。我所做的是从DataContract中获取字符串属性（在OperationContract中按名称获取它们，如下所示：

[OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "count_customers")]
    string PostCount(string subsidiarySid, string storeSid, string date, IEnumerable<Counter> counters);

和DataContract

[DataContract(Name = "counter")]
public class Counter
{
    [DataMember(Name = "nationalitySid")]
    public string nationalitySid;

    [DataMember(Name = "count")]
    public string count;
}

只需删除DataContract定义中的“Name”属性，我就可以省略不必要的“data：{}”图层。
