もう半年が経ったんだー。前半はトラブル対応のみだったな。

_ [Flash] JSONでRestful(POSTとGET)

合間を見つけてはコードをかいてみました。

ActionScriptでJSONをハンドリングするには、mikechambers/as3corelib · GitHubが便利です。

仕事ではPOSTを多用しそうです。GETが簡単ですけどね。POSTの時は配列になっているのはご愛敬です。:-P

_ [.NET][WCF] JSONでRestful（サーバー）

.NETのほうがJavaより慣れているのです。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.ServiceModel.Activation;
using System.Text;
using System.IO;

namespace RestJsonService
{
   [ServiceContract]
   public interface IRestfulService
   {
       [OperationContract]
       [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "GetSampleMethod/{name}")]
       string GetSampleMethod(string name);

       [OperationContract]
       [WebInvoke(Method = "POST",
           RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json,
           UriTemplate = "PostSampleMethod")]
       PostSampleResponse PostSampleMethod(Stream stream);
   }
   [AspNetCompatibilityRequirements(RequirementsMode=AspNetCompatibilityRequirementsMode.Required)]
   public class RestfulService : IRestfulService
   {
       public string GetSampleMethod(string name)
       {
           return "こんにちは" + name + "さん";
       }

       public PostSampleResponse PostSampleMethod(Stream stream)
       {
           DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(PostSampleRequest[]));
           PostSampleRequest [] req = (PostSampleRequest [])serializer.ReadObject(stream);
           return new PostSampleResponse
           {
               Message = req[0].Name
           };
       }
   }

   [DataContract]
   public class PostSampleRequest{
       [DataMember(Name="Name")]
       public string Name{ get; set;}
   }
   [DataContract]
   public class PostSampleResponse{
       [DataMember(Name="Message")]
       public string Message {get; set;}
   }
}

あとGlobal.asax.csで

protected void Application_Start(object sender, EventArgs e)
       {
           RouteTable.Routes.Add(
               new ServiceRoute("RestfulService",
                   new WebServiceHostFactory(),
                   typeof(RestfulService))
               );
       }

_ [買物][本] 面積迷路 (学研ムック)

電車の吊り広告で釣られました。解けるには解けたのだがちょっと時間がかかって悔しかった。
