WCF教學(5) - 使用程式裝載服務

 

延續 WCF教學(4) - 設計Console Client

本練習利用程式的方式，建立ServiceHost物件裝載服務，並透過程式加入服務Endpoint

• 刪掉 Host  app.config組態檔 (ConsoleApplication1)
• 修改Host(ConsoleApplication1) ,Main方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using WcfServiceLibrary1;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Service is running...");
            ServiceHost myHost = new
                  ServiceHost(typeof(Calc));
            myHost.AddServiceEndpoint(typeof(IMyService),
                             new BasicHttpBinding(),
                             "http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/");
            myHost.Open();
            Console.ReadLine();
        }
    }
}

• 按CTRL + F5執行，Client可以正確呼叫Service

目前程式雖然可以正確執行，但因為沒有開放Metadata端點，因此，當你執行Host (ConsoleApplication1) 後，開啟Browser，輸入以下URL

http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/mex

你將無法取得WSDL

• 修改Main方法，建立ServiceMetadataBehavior開放Metadata

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using WcfServiceLibrary1;
using System.ServiceModel.Description;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Service is running...");
            ServiceHost myHost = new
                  ServiceHost(typeof(Calc));
            myHost.AddServiceEndpoint(typeof(IMyService),
                             new BasicHttpBinding(),
                             "http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/");

            var metadataBehavior = new ServiceMetadataBehavior();
            metadataBehavior.HttpGetEnabled = true;
            metadataBehavior.HttpGetUrl = new Uri("http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/mex");
            myHost.Description.Behaviors.Add(metadataBehavior);

            myHost.Open();
            Console.ReadLine();
        }
    }
}

 

• CTRL+F5執行
• 在Browser

http://localhost:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/mex

可以看到WSDL:
