关键代码如下:
public interface IService
    {
        [OperationContract(Name="sayHelloJson")]
        [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "sayHello", BodyStyle = WebMessageBodyStyle.Wrapped)]
        String sayHello();
        [OperationContract(Name = "SendMessageJson")]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "SendMessage?Message={Message}", BodyStyle = WebMessageBodyStyle.Wrapped)]
        String SendMessage(String Message);
    }static void Main(string[] args)
        {
            Uri ea = new Uri("http://localhost:8000/Service");
            WebHttpBinding bb = new WebHttpBinding();
            ServiceHost sh = new ServiceHost(typeof(Service),ea);
            ServiceMetadataBehavior behave = new ServiceMetadataBehavior();
            behave.HttpGetEnabled = true;
            sh.Description.Behaviors.Add(behave);
            sh.AddServiceEndpoint(typeof(IService),bb,ea);
            try
            {
                sh.Open();
                Console.WriteLine("启动成功……");
                Console.ReadLine();
                sh.Close();
            }
            catch
            {
                Console.WriteLine("启动失败……");
            }        }
没使用配置文件
浏览器访问http://localhost:8000/Service正常
现在想在浏览器中查看sayHello方法的返回数据
http://localhost:8000/Service/Json/sayHello无法打开
到底哪里有问题?
