我需要创建一个位于服务器(托管在IIS中)的WCF服务,并侦听任何HTTP GET请求在某个URL处击中服务器。用于处理HTTP GET请求的WCF服务

更具体地说,当一个有效的GET请求到达服务器时,Id想要检查在URL中编码的参数。

下面是我的界面代码:

[ServiceContract] 
public interface IHttpHandler 
{ 
    [OperationContract(Action = "*", ReplyAction = "*")] 
    void HandleMessage(Message m); 

    [OperationContract] 
    [WebInvoke(UriTemplate = "HandleEchoRequest", Method = "GET")] 
    string HandleEchoRequest(Stream request); 
} 

执行代码(svc.cs文件):

public void HandleMessage(Message m) 
{ 
    //do some work 
} 

public string HandleEchoRequest(Stream request) 
{ 
    //...do something here 
    return "asdf"; 
} 

我能成功击中SVC:

http://localhost/HttpMessageProcessor/HttpHandler.svc 

然而,当我连接到W3WP流程时,我似乎无法进入转折点集。最终Id喜欢使用HTTPS。

在WCF服务项目我的web.config文件:

<system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    </system.web> 
    <system.serviceModel> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior> 
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> 
      <serviceMetadata httpGetEnabled="true"/> 
      <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
      <serviceDebug includeExceptionDetailInFaults="false"/> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
    </system.serviceModel> 
<system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer> 

的App.config在客户端:

<system.serviceModel> 
    <behaviors> 
     <endpointBehaviors> 
     <behavior name="webBehavior"> 
      <webHttp/> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    <bindings> 
     <basicHttpBinding> 
     <binding name="BasicHttpBinding_IHttpHandler" /> 
     </basicHttpBinding> 
    </bindings> 
    <client> 
     <endpoint address="http://localhost/HttpMessageProcessor/HttpHandler.svc" 
     behaviorConfiguration="webBehavior" binding="webHttpBinding" 
     contract="Proxy.IHttpHandler" name="BasicHttpBinding_IHttpHandler" /> 
    </client> 
    </system.serviceModel> 

客户端代码:

using (var service = new Proxy.HttpHandlerClient()) 
{ 
} 

Console.ReadKey(); 

我想两件事情看看我是否可以进入代码: 1.点击CTRL + F5在控制台项目上启动客户端,然后查看我是否可以附加到W3WP进程。 2.运行在调试模式下的客户端,看看我能指向一个URL,例如:

http://localhost/HttpMessageProcessor/HttpHandler.svc/HandleEchoRequest/ 

上述方法都不似乎工作。

我已经看过网络的建议,并尝试了一些事情,我已经休息了我在这里提到的代码。任何建议/想法的欢迎!

编辑 我遇到了this网站,并实现了一个简单的解决方案如下。 我能成功击中断点的handleMessage执行设定当我在浏览器中输入以下网址:

代码:

[ServiceContract] 
public interface IService1 
{ 
    [OperationContract(Action = "*", ReplyAction = "*")] 
    void HandleMessage(Message m); 
} 

public class Service1 : IService1 
{ 
    public void HandleMessage(Message m) 
    { 
     //do something here. 
    } 
} 

App.config中的服务:

<system.serviceModel> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior> 
      <serviceMetadata httpGetEnabled="True"/> 
      <serviceDebug includeExceptionDetailInFaults="False"/> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    </system.serviceModel> 

我的客户代码:

Uri baseAddress = new Uri("http://localhost/TestWCFSite/TestWCFService.svc/"); 
Uri endpointAddress = new Uri("http://localhost/TestWCFSite/TestWCFService.svc/HandleMessage/"); 
var binding = new CustomBinding(new TextMessageEncodingBindingElement(MessageVersion.None, Encoding.UTF8), new HttpTransportBindingElement()); 
ServiceHost service = new ServiceHost(typeof(Service1), baseAddress); 
service.AddServiceEndpoint(typeof(IService1), binding, endpointAddress); 
service.Open(); 

var message = string.Format("Service open at {0} - press a key to continue", baseAddress); 

Console.WriteLine(message); 
Console.ReadKey(); 
service.Close(); 

我的问题是现在试图在IIS中承载它并让它处理断点命中。

假设你使用的是Visual Studio--如果你通过Tools-> Attach to Process ...进行连接,会发生什么?

只是为了仔细检查,我假设你从WCF服务项目而不是客户端项目附加? (我对此作出回应表示歉意,我代表太低而无法发表评论。)

嘿,你好 - 使用Visual Studio。我在同一个解决方案中获得了客户端和WCF服务。当我附上时,它表示客户端代码不会被纳入..合理。 WCF代码是鲜红的,这意味着它应该打... – TheRenoRanger
