Post请求Json格式数据到WCF服务

测试实体类:(需要在客户端和服务端建了有相同字段名称的实体)

public class CompositeType
    {
        public CompositeType()
        {
            SubCompositeTypes = new List() { new SubCompositeType() };
        }
        public bool BoolValue { get; set; }
        public string StringValue { get; set; }
        public List SubCompositeTypes
        {
            get;
            set;
        }
    }
    public class SubCompositeType
    {
        bool boolValue = true;
        string stringValue = "Hello ";
        public bool BoolValue
        {
            get { return boolValue; }
            set { boolValue = value; }
        }
        public string StringValue
        {
            get { return stringValue; }
            set { stringValue = value; }
        }
    }

客户端请求代码:


#region JosnPost
    CompositeType compositeType = new CompositeType
    {
        StringValue = "1",
        BoolValue = false
    };

    DataContractJsonSerializer dcSerializer = new DataContractJsonSerializer(typeof(CompositeType));

    MemoryStream stream = new MemoryStream();

    dcSerializer.WriteObject(stream, compositeType);

    string data = Encoding.UTF8.GetString(stream.ToArray(), 0, (int)stream.Length);

    //HttpClient client = new HttpClient();

    //client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    string link = "http://localhost:1766/Service1.svc/CreateUser";

    //HttpResponseMessage respondse = await client.PostAsync(link, new StringContent(data));

    //string dataWithJason = await respondse.Content.ReadAsStringAsync();

    var request = (HttpWebRequest)WebRequest.Create(new Uri(link));
    request.ContentType = "application/json";
    request.Method = "POST";

    using (var requestStream = await request.GetRequestStreamAsync())
    {
        var writer = new StreamWriter(requestStream);
        writer.Write(data);
        writer.Flush();
    }

    using (var resp = await request.GetResponseAsync())
    {
        using (var responseStream = resp.GetResponseStream())
        {
            var reader = new StreamReader(responseStream);
            var result = reader.ReadToEnd();
        }
    }



服务端接口定义:

[OperationContract]
        [WebInvoke(
            UriTemplate = "CreateUser",
            RequestFormat = WebMessageFormat.Json,
            ResponseFormat = WebMessageFormat.Json,
            Method = "POST")]
        string CreateUser(CompositeType compositeType);



服务端接口实现:

public string CreateUser(CompositeType compositeType)
        {
            return "OK" + compositeType.StringValue + " " + compositeType.BoolValue + " " + compositeType.SubCompositeTypes.FirstOrDefault().StringValue;
        }

由于服务端需要实现REST服务,需要在web.config里重新配置下(cover serviceModel就可以了):



   
     
       
         
           
         
       
       
     
   
   
     
       
         
       
     
     
       
         
          psGetEnabled="true"/>
         
          includeExceptionDetailInFaults="false"/>
       
     
   
   
     
   
   
 


经测试，在windows runtime项目中也可以用。
