在IIS7上部署WCF教程应用程序:“无法找到类型”

标签: wcf iis-7 iis-manager

我一直在尝试按照此tutorial将WCF示例部署到IIS。 我无法让它发挥作用。这是一个托管站点,但我确实有IIS管理员访问服务器。但是,在本教程的第2步中,我无法“创建一个物理上位于此应用程序目录中的新IIS应用程序”。我似乎无法找到菜单项,上下文菜单项或什么不创建新的应用程序。我一直在疯狂地点击所有地方,仍然无法弄清楚如何创建一个新的应用程序。我想这可能是根本问题,但我尝试了其他一些事情(如下所述)以防万一实际上不是问题。这是我在IIS管理器中看到的图片,以防我的话不公正:

No add Application Here http://www.freeimagehosting.net/uploads/d6edbaaf3c.png

这是在http://test.com.cws1.my-hosting-panel.com/IISHostedCalcService/Service.svc“部署”的。错误说:

    The type 'Microsoft.ServiceModel.Samples.CalculatorService', 
provided as the Service attribute value in the ServiceHost directive, 
or provided in the configuration element
 system.serviceModel/serviceHostingEnvironment/serviceActivations 
could not be found.

我还尝试在dotnetpanel中创建一个指向IISHostedCalcService的虚拟目录(IISHostedCalc)。当我导航到http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc时,会出现另一个错误:

This collection already contains an address with scheme http.  
There can be at most one address per scheme in this collection.

有趣的是,如果我点击查看应用程序,虚拟目录似乎是一个应用程序(见下图)...尽管如上所述,它不起作用。

Is this an app or not? http://www.freeimagehosting.net/uploads/f3230be046.png

根据教程,没有涉及编译;我刚刚将文件放在服务器上,如下面的文件夹IISHostedCalcService:

service.svc
Web.config
<dir: App_Code>
   Service.cs

service.svc包含:

<%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService"%>

(我尝试使用c#属性的引号,因为这看起来有点奇怪没有引号,但它没有区别)

Web.config包含:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="Microsoft.ServiceModel.Samples.CalculatorService">

        <!-- This endpoint is exposed at the base address provided by host:                                        http://localhost/servicemodelsamples/service.svc  -->
        <endpoint address=""
                  binding="wsHttpBinding"
                  contract="Microsoft.ServiceModel.Samples.ICalculator" />

        <!-- The mex endpoint is explosed at http://localhost/servicemodelsamples/service.svc/mex -->
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
  </system.serviceModel>
  <system.web>
    <customErrors mode="Off"/>
  </system.web>
</configuration>

Service.cs包含:

using System;
using System.ServiceModel;

namespace Microsoft.ServiceModel.Samples
{

    [ServiceContract]
    public interface ICalculator
    {
        [OperationContract]
        double Add(double n1, double n2);
        [OperationContract]
        double Subtract(double n1, double n2);
        [OperationContract]
        double Multiply(double n1, double n2);
        [OperationContract]
        double Divide(double n1, double n2);
    }


    public class CalculatorService : ICalculator
    {
        public double Add(double n1, double n2)
        {
            return n1 + n2;
        }
        public double Subtract(double n1, double n2)
        {
            return n1 - n2;
        }
        public double Multiply(double n1, double n2)
        {
            return n1 * n2;
        }
        public double Divide(double n1, double n2)
        {
            return n1 / n2;
        }
    }
}

4 个答案:

答案 0 :(得分:7)

嗯,好像我有这个工作了。我仍然无法在IIS管理器中找到“创建应用程序”项。那部分有点令人沮丧,但我很高兴它似乎仍在工作。

我在wwwroot下创建了物理目录IISHostedCalcService。这造成了一些混乱;这意味着http://test.com.cws1.my-hosting-panel.com/IISHostedCalcService/Service.svc几乎正在运作,但它不应该。我将IISHostedCalcService移到了wwwroot之外,现在访问该服务的唯一地方是http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc

然后,访问http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc正在抛出“此集合已包含带有方案http的地址 此集合中每个方案最多只能有一个地址。“错误。事实证明,解决方法是将以下内容添加到web.config文件中,就在system.serviceModel下:

<serviceHostingEnvironment>
  <baseAddressPrefixFilters>
    <add prefix="http://test.com.cws1.my-hosting-panel.com"/>
  </baseAddressPrefixFilters>
</serviceHostingEnvironment>

之后我在访问http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc时遇到新错误:“在服务CalculatorService实现的合同列表中找不到合同名称IMetadataExchange”。事实证明,解决方案是修改web.config文件,如下所示(即,在service元素中添加behavior部分和behaviorConfiguration =“SimpleServiceBehavior”):

<configuration>
  <system.serviceModel>
    <serviceHostingEnvironment>
      <baseAddressPrefixFilters>
        <add prefix="http://test.com.cws1.my-hosting-panel.com"/>
      </baseAddressPrefixFilters>
    </serviceHostingEnvironment>
    <services>
      <service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="SimpleServiceBehavior">
      ...
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="SimpleServiceBehavior">
          <serviceMetadata httpGetEnabled="True" policyVersion="Policy15" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <system.web>
    <customErrors mode="Off"/>
  </system.web>
</configuration>

最后,我能够通过在http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/service.svc?wsdl的教程的步骤5c中将svcutil指向http://msdn.microsoft.com/en-us/library/ms733133.aspx来创建客户端代理。但是,当我运行客户端时,我得到了“调用者未通过服务进行身份验证”错误。对此的解决方案是最简单的:只需将binding =“wsHttpBinding”更改为服务的web.config中的binding =“basicHttpBinding”和客户端的web.config(或者在更改服务的web.config后重新运行svcutil)。

web.config最终看起来像这样:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <serviceHostingEnvironment>
      <baseAddressPrefixFilters>
        <add prefix="http://test.com.cws1.my-hosting-panel.com"/>
      </baseAddressPrefixFilters>
    </serviceHostingEnvironment>
    <services>
      <service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="SimpleServiceBehavior">

        <!-- This endpoint is exposed at the base address provided by host:                                        http://localhost/servicemodelsamples/service.svc  -->
        <endpoint address=""
                  binding="basicHttpBinding"
                  contract="Microsoft.ServiceModel.Samples.ICalculator" />

        <!-- The mex endpoint is explosed at http://localhost/servicemodelsamples/service.svc/mex -->            
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />

      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="SimpleServiceBehavior">
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true" policyVersion="Policy15" />
          <!-- 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>
  </system.serviceModel>
  <system.web>
    <customErrors mode="Off"/>
  </system.web>
</configuration>

答案 1 :(得分:4)

要创建新应用程序,请右键单击“默认网站”节点。从上下文菜单中选择Add Application。

答案 2 :(得分:1)

我遇到了同样的错误,对我来说,问题只是我在服务器上缺少了要编译的服务所需的程序集。

这里描述的所有内容对我来说都没有必要。

要了解您的错误,可以尝试将service.svc和service.svc.cs文件移动到App_Code目录。这样,您将收到与您遇到的真实错误更相关的错误消息。

就我而言,由于忘记部署某些程序集而丢失了名称空间。我上传了丢失的程序集,正确运行服务然后移回了他们所属的服务文件。

答案 3 :(得分:1)

我有这个问题。

  1. 我在wwwroot
  2. 下保留了已发布的文件
  3. 单击.svc文件上的浏览
  4. 抛出同样的异常
  5. 分辨率

    1. 我为同一个
    2. 创建了一个虚拟目录
    3. 尝试浏览.svc文件。
    4. ...工作
