ADO.NET Data Services 的Self-Hosting例子(.NET 3.5 SP1)

ccBoy — Sun, 10 Aug 2008 15:23:57 GMT

之前有写一篇关于ADO.NET Data Services hosting在一个控制台程序中的做法。
详细见--ADO.NET Data Services 的Self-Hosting实例
http://blogs.msdn.com/ccboy/archive/2008/01/12/ado-net-data-services-self-hosting.aspx
今天找了一下，发现原来的代码找不到，于是重新尝试了一下，看看.NET 3.5 SP1之后是否有变化。

ADO.NET Data Services逐渐成为一个非常不错的工具和武器，它完美的和ADO.NET Entity Framework结合，可以说很大程度弥补了EF目前分布式开发的短板，同时Data Services本身也成功的削弱了WCF原来基于SOAP的组件通信的沉重，可以说利用了WCF最好的部分。

例子分为测试了两种情况，一种是使用WCF配置文件的方式；一种是不需要配置文件的方式。
当baseAddress 参数传空，系统会默认是使用配置文件的方式。

另外例子尝试使用自定义的数据源，即非ADO.NET EF和 SQL To LINQ的方式。

例子可以在这里下载：

ADO.NET Data Services 的Self-Hosting实例

Fast, simple test app for ADO.NET Data Services

Mike Taulty 的Weblog
http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2007/12/19/10028.aspx

以及Christian Weyer的Weblog
http://blogs.thinktecture.com/cweyer/archive/2007/12/11/415057.aspx

都有讨论Astoria ServiceHost在一个控制台的应用中，因为目前版本的Astoria CTP只提供了WebHosting/ASP.NET(模式)，当然这非常容易应用在Web开发的环境中，看了他们的Weblog，自己测试了一下，果然是可行的。

1.先创建一个控制台的应用(VS2008)
2.增加一个ADO.NET Entity Data Model(或者是加入一个已经创建EDM Lib的项目引用) 创建一个ObjectContext，比如：BlogEntities
3.创建SvcImp的cs文件，实现WebDataService (BlogSvcImp.cs)

using System;
using System.Web;
using System.Collections.Generic;
using System.ServiceModel.Web;
using System.Linq;
using Microsoft.Data.Web;
using BlogModel;

namespace SelfHostSvc
{
    public class BlogSvcSelfHost : WebDataService<BlogEntities>
    {
         public static void InitializeService(IWebDataServiceConfiguration config)
        {
             config.SetResourceContainerAccessRule("*", ResourceContainerRights.AllRead);

            // Example for service operations
            // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All);
        }

}
}

4.修改App.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
    <services>
      <service name="SelfHostSvc.BlogSvcSelfHost" behaviorConfiguration="webHttp_SelfHost">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:9909/DataServices/SelfHost/BlogSvc"/>
          </baseAddresses>
        </host>
        <endpoint
          address=""
          binding="webHttpBinding"
          contract="Microsoft.Data.Web.IRequestHandler" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="webHttp_SelfHost">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
</system.serviceModel>

5.控制台Main应用中增加下面的代码

static void Main(string[] args)
{

WebServiceHost host = new WebServiceHost(typeof(BlogSvcSelfHost));
host.Open();

Console.WriteLine("Service starting....\nPress Enter to exit");
Console.ReadLine();

host.Close();

}

之后就可以启动这个控制台应用。在IE浏览器中访问下面的地址

http://localhost:9909/DataServices/SelfHost/BlogSvc

接着可以通过简单的REST命令简单访问服务
http://localhost:9909/DataServices/SelfHost/BlogSvc/Blogs

用下面的链接获得Astoria服务的元数据信息
http://localhost:9909/DataServices/SelfHost/BlogSvc/$metadata

从上面看出，通过控制台的Self-Hosting方式也可以实现Astoria Service，Astoria提供了一个通用的数据服务的架构和基础工具，借助.NET 3.5的WCF功能，你可以更加方便的开发自己的Internet数据服务。
