Question

我使用RestSharp。

我有一个列表private List<string> _GuyIds;然后

        [TestMethod]
    public void GuyMetadataServiceShouldReturnExpected()
    {
        var client = new RestClient("http://localhost/OrionServices/GuyService.svc/");

        var request = new RestRequest("{facilityId}/Guys/metadata/", Method.POST);
        request.AddUrlSegment("facilityId", "888");
        request.AddParameter("GuyIds", JsonConvert.SerializeObject(_GuyIds.ToArray()), ParameterType.RequestBody);

        var response = client.Execute(request);
        dynamic data = JsonConvert.DeserializeObject<dynamic>(response.Content);

在服务中，

        [OperationContract]
    [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedResponse, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/{FacilityID}/Guys/metadata/")]
    public List<dynamic> GenerateMetadata(string FacilityID)
    {
        WebOperationContext.Current.OutgoingResponse.Headers.Add("Cache-Control", "no-cache, must-revalidate");
        WebOperationContext.Current.OutgoingResponse.Headers.Add("Expires", "Sat, 26 Jul 1997 05:00:00 GMT");

        var Guys = Encoding.UTF8.GetString(OperationContext.Current.RequestContext
            .RequestMessage.GetBody<byte[]>());

当我将鼠标悬停在服务代码中的Guys上时，我得到了

["0001","0003","0004","0005","0006"]

但是，当我检查响应时，内容为空。当我将数组传递给此行中的请求时，我猜错了。

request.AddParameter("GuyIds", JsonConvert.SerializeObject(_GuyIds.ToArray()), ParameterType.RequestBody);

如何解决？

自己弄清楚。 WCF不支持序列化动态类型。我必须定义一个POCO对象。

   [OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedResponse, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/{FacilityID}/Guys/metadata/")]
public List<GuysDTO> GenerateMetadata(string FacilityID)
{
    WebOperationContext.Current.OutgoingResponse.Headers.Add("Cache-Control", "no-cache, must-revalidate");
    WebOperationContext.Current.OutgoingResponse.Headers.Add("Expires", "Sat, 26 Jul 1997 05:00:00 GMT");

然后

public class GuyDTO
{
     public string metadata1 {get;set;}
      ....
}

请求addparameter数组但在响应中返回空
