HTTP POST を使用して文字列のみを含む json を送信する WCF サービス アプリケーション (REST) を作成しています。サービスをテストするために PostMan というプログラムを使用して json を送信しているときに、HTTP ステータス コード 400 Bad Request を取得しています。ソースコードを以下に示します:-
IService1.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfImageUpload
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(UriTemplate = "/JsonData",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json, Method = "POST")]
bool SendData(JsonString JsonImage);
// TODO: Add your service operations here
}
// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class JsonString
{
[DataMember]
public string ImageData { get; set; }
}
}
Service1.svc.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfImageUpload
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class Service1 : IService1
{
public bool SendData(JsonString JsonImage)
{
return true;
}
}
}
