WCF Rest API：如何使用邮递员发送字典

Question

我有以下接口和实现。

** Interface **
public interface IAPIHelper
{
    //RESTFul API
    [FaultContract(typeof(RequestValidationFault))]
    [WebInvoke(UriTemplate = "/ByteFromData", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)]
    [OperationContract]
    byte[] ByteFromData(ByteFaRequest HashMap);
}

 *** Data contract ***

[DataContract]
public class ByteFaRequest 
{
    [DataMember]
    public Dictionary<string, string[]> HashMap;
}


  ***Implementation****

[ServiceBehavior]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class APIHelper : IAPIHelper
{
    public byte[] ByteFromData(ByteFaRequest data)
    {
        // Business Logic
    }
}

现在，我正在尝试使用邮递员检查此 api，但我没有在参数中获得任何值，尽管我可以调用其他 get/post WCF REST api秒。我在邮递员中创建 JSON 请求时遗漏了什么吗？

 json request - 
 {
   "HashMap" : {"key1":["1.1","1.2"],"key2":["2.1","2.2"],"key3":["3.1","3.2"]}
 }

调用 api 后 - 我没有在字典对象中获取数据。

json 请求中缺少什么？

Answer 1

应该是一个以属性为key和value的数组试试下面的请求

{
   "HashMap" : [
                {"key": "key1", "value": ["1.1","1.2"]},
                {"key": "key2", "value": ["2.1","2.2"]}
               ]
 }
