C# 公开自托管服务时从配置文件programmticlally读取WCF行为元素

我的app.config中有此配置：

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

然后添加端点及其绑定：

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

var binding = new BasicHttpBinding("myBinding");
host.AddServiceEndpoint(typeof(IMyInterface), binding, "MyName");

现在，我想用从配置文件中读取名为myBehavior的行为的代码替换下面的代码，而不是硬编码行为选项。

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

ServiceMetadataBehavior smb = new ServiceMetadataBehavior() { HttpGetEnabled = true };    
host.Description.Behaviors.Add(smb);   
// Enable exeption details
ServiceDebugBehavior sdb = host.Description.Behaviors.Find<ServiceDebugBehavior>();
sdb.IncludeExceptionDetailInFaults = true;

*编辑*

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

使用配置文件配置服务

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

您不应该需要这种方式，您应该让主机从配置文件自动获取其配置，而不是手动提供，读取，这将帮助您，我在C#中的一行中托管了我的服务，在配置中很少托管

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

,， 我的错是我试图把这两种方法混为一谈

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

我将添加此作为答案。

首先，您需要使用

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

或

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

然后您阅读以下行为：

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

var bindings = BindingsSection.GetSection(config);
var group = ServiceModelSectionGroup.GetSectionGroup(config);
foreach (var behavior in group.Behaviors.ServiceBehaviors)
{
    Console.WriteLine ("BEHAVIOR: {0}", behavior);
}

请注意，它们属于

System.ServiceModel.Configuration.ServiceBehaviorElement类型，因此还不是您想要的类型

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

如果您不介意使用私有API，可以通过反射调用受保护的方法
BehaviorExtensionElement.CreateBehavior（）
：

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

foreach (BehaviorExtensionElement bxe in behavior)
{
    var createBeh = typeof(BehaviorExtensionElement).GetMethod(
        "CreateBehavior", BindingFlags.Instance | BindingFlags.NonPublic);
    IServiceBehavior b = (IServiceBehavior)createBeh.Invoke(bxe, new object[0]);
    Console.WriteLine("BEHAVIOR: {0}", b);
    host.Description.Behaviors.Add (b);
}

使用配置文件配置服务

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

您不应该需要这种方式，您应该让主机从配置文件自动获取其配置，而不是手动提供，读取，这将帮助您，我在C#中的一行中托管了我的服务，在配置中很少托管

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

,，
我的错是我试图把这两种方法混为一谈
 虽然这是一个老问题，但我在其他地方找不到我需要的东西，所以这里是我的解决方案，供将来参考

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

var behaviorSection = ConfigurationManager.GetSection("system.serviceModel/behaviors") as BehaviorsSection;
if (behaviorSection != null)
{
                // for each behavior, check for client and server certificates
    foreach (EndpointBehaviorElement behavior in behaviorSection.EndpointBehaviors)
    {
        foreach (PropertyInformation pi in behavior.ElementInformation.Properties)
        {
            if (pi.Type == typeof(ClientCredentialsElement))
            {
                var clientCredentials = pi.Value as ClientCredentialsElement;
                var clientCert = clientCredentials.ClientCertificate;
                            // TODO: Add code...
            }
        }
    }
}

ConfigurationManager.Open…Configuration（）
不能很好地处理web项目，因此手动获取节并强制转换它更简单

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

如果您确实坚持让
System.ServiceModel
为您进行配置读取，则可以执行以下操作：

    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

ExeConfigurationFileMap map = new ExeConfigurationFileMap();
map.ExeConfigFilename = System.IO.Path.Combine(HttpContext.Current.Server.MapPath("~"), "web.config"); // the root web.config  
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None);
var group = ServiceModelSectionGroup.GetSectionGroup(config);

foreach (EndpointBehaviorElement item in group.Behaviors.EndpointBehaviors)
{
    // TODO: add code...
}

第二种方法使用
HttpContext.Current
，我们都知道
HttpContext.Current
在进行单元测试时非常糟糕。
有合理的理由不使用配置文件，即从外部源检索地址等。除非您不想使用默认配置文件
    </binding>
  </basicHttpBinding>
</bindings>



<behaviors>
  <serviceBehaviors>
    <behavior name="myBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
