如何在IIS环境中以编程方式注册WCF服务 [英] How can I register a WCF service programmatically within an IIS environment

问题描述

假设我们有2个具有以下布局的项目

Let's say we have 2 projects with following layout

• 项目 web
  
  
  
  • global.asax（我想到了要在例如 void Application_Start（System.Object sender，System.EventArgs e ）内进行注册的目的地）
  
  
  • web.config
  
  
  • Project "web"
    • global.asax (I thought of this destination for registration within eg void Application_Start(System.Object sender, System.EventArgs e)
    • web.config
    
    
    • DemoService.cs
    
    
    • IDemoService.cs
    
    

    web.config 看起来像这样

    <configuration>
        <system.serviceModel>
            <behaviors>
                <serviceBehaviors>
                    <behavior name="fooBehavior">
                        <serviceMetadata httpGetEnabled="true" />
                    </behavior>
                </serviceBehaviors>
            </behaviors>
            <services>
                <service name="wcf.DemoService"
                         behaviorConfiguration="fooBehavior">
                    <endpoint address="mex"
                              binding="mexHttpBinding"
                              contract="IMetadataExchange" />
                    <endpoint address=""
                              binding="wsHttpBinding"
                              contract="wcf.IDemoService" />
                </service>
            </services>
        </system.serviceModel>
    </configuration>
    

    所以...现在...某处（如上所述，我想到了 global.asax ）我需要注册，当浏览到 URI wcf.DemoService 时，解决该问题并获得mex-request wcf.IDemoService 被解析为读取属性以获得WSDL。

    So ... now ... somewhere (as mentioned above I thought of global.asax) I need to register, that when browsing to URI wcf.DemoServiceget's resolved and for a mex-request the wcf.IDemoService gets resolved for reading the attributes to get a WSDL.

    通常通过创建 .svc 文件并将标题放在第一行来完成，例如：

    This would usually be done by creating a .svc file and put header in the first line, e.g.:

    <%@ ServiceHost Language="C#" Debug="true" Service="wcf.DemoService" %>
    

    例如控制台应用程序

    var serviceHost = new ServiceHost(typeof (wcf.DemoService));
    serviceHost.Open();
    

    并将其与 host 元素组合 service 元素来指定 URI -或使用 ServiceHost

    And combine this with a host element within the service element to specify the URI - or use another ctor-overload of ServiceHost

    但是我宁愿进行静态注册（或任何适用于IIS 7.5的 web.config 注册）-这可能吗？如果是，怎么办？

    But I would rather go for a static registration (or any web.config registration which works for IIS 7.5) - is this possible? If so, how?

    推荐答案

    WCF 4（.NET 4.0）提供基于代码的服务注册和基于配置的服务注册

    WCF 4 (.NET 4.0) offers both code based registration of services and configuration based registration of services.

    基于代码的配置是通过新的 ServiceRoute ：

    Code based configuration is achieved through ASP.NET Routing by new ServiceRoute:

    RouteTable.Routes.Add(new ServiceRoute("DemoService", 
                              new ServiceHostFactory(), typeof(wcf.DemoService));
    

    路由通常与REST服务一起使用，但它也适用于SOAP服务。

    Routes are usually used with REST services but it works for SOAP services as well.

    在配置中注册服务称为< a href = http://msdn.microsoft.com/en-us/library/dd807499.aspx>基于配置的激活。您将在web.config中定义虚拟.svc文件：

    Registering service in configuration is called configuration based activation. You will define virtual .svc file in web.config:

    <serviceHostingEnvironment>
       <serviceActivation>
          <add relativeAddress="DemoService.svc" service="wcf.DemoService" />
       </serviceActivation>
    </serviceHostingEnvironment>
    

    在这两种情况下，您都只定义了服务的相对路径，因为基址始终由网络指定网站托管在IIS中。

    In both cases you are defining only relative path to your service because base address is always specified by your web site hosted in IIS.
