c# - WCF 找不到端点配置问题

标签 c# wcf configuration wcf-binding wcf-client

我有一个 WCF 网络服务，我正在我的本地机器上测试这让我头疼。

我的服务配置如下:

<system.serviceModel>
   <services>
      <service name="GHMDatroseIntegration.GHMDatroseWCFService.DatroseService" 
               behaviorConfiguration="DatroseServiceBehavior">
         <endpoint 
             address="mex"
             binding="basicHttpBinding" 
             contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService" />
      </service>
   </services>
   <behaviors>
      <serviceBehaviors>
         <behavior name="DatroseServiceBehavior">
            <serviceMetadata httpGetEnabled="true"/>
            <serviceDebug includeExceptionDetailInFaults="true"/>
            <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
         </behavior>
      </serviceBehaviors>
   </behaviors>
   <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

我的客户端配置如下:

<system.serviceModel>
   <bindings>
      <basicHttpBinding>
         <binding name="BasicHttpBinding_IDatroseService" 
             closeTimeout="00:02:00" openTimeout="00:01:00" 
             receiveTimeout="00:10:00" sendTimeout="00:02:00"
             allowCookies="false" bypassProxyOnLocal="false" 
             hostNameComparisonMode="StrongWildcard"
             maxBufferSize="524288" maxBufferPoolSize="524288" 
             maxReceivedMessageSize="524288" 
             messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
             useDefaultWebProxy="true">
            <readerQuotas 
                 maxDepth="32" maxStringContentLength="524288" 
                 maxArrayLength="524288" maxBytesPerRead="524288" 
                 maxNameTableCharCount="524288" />
            <security mode="None">
                 <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                 <message clientCredentialType="UserName" algorithmSuite="Default" />
            </security>
         </binding>
      </basicHttpBinding>
   </bindings>
   <client>
       <endpoint name="BasicHttpBinding_IDatroseService"
           address="http://localhost/DatroseWCFService/DatroseService.svc"  
           behaviorConfiguration="DatroseServiceBehavior"
           binding="basicHttpBinding"  
           bindingConfiguration="BasicHttpBinding_IDatroseService"
           contract="DatroseWCFService.IDatroseService"  />
   </client>
   <behaviors>
      <endpointBehaviors>
         <behavior name="DatroseServiceBehavior">
             <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
         </behavior>
      </endpointBehaviors>
   </behaviors>
 </system.serviceModel>

我收到的错误是:

There was no endpoint listening at http://localhost/DatroseWCFService/DatroseService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

...然而，如果我浏览到该位置，我会看到服务屏幕，所以它似乎设置正确。

我确定这与我的端点配置有关，但我无法弄清楚它们应该是什么样子。在这里提供一些帮助将不胜感激。

更新 糟糕，我输入了错误的错误消息。现在已修复。

UPDATE 2 根据我认为这些回复中的建议，我已将我的服务器配置更改为:

<system.serviceModel>
   <services>
      <service name="GHMDatroseIntegration.GHMDatroseWCFService.DatroseService" 
               behaviorConfiguration="DatroseServiceBehavior">
         <endpoint 
             address="/svc"
             binding="basicHttpBinding"
             contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService"  />
         <endpoint 
             address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
       </service>
   </services>
   <behaviors>
       <serviceBehaviors>
          <behavior name="DatroseServiceBehavior">
             <serviceMetadata httpGetEnabled="true"/>
             <serviceDebug includeExceptionDetailInFaults="true"/>
             <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
          </behavior>
       </serviceBehaviors>
   </behaviors>
   <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

我的客户端配置为:

<system.serviceModel>
   <bindings>

         <binding name="BasicHttpBinding_IDatroseService" 
             closeTimeout="00:02:00" openTimeout="00:01:00" 
             receiveTimeout="00:10:00" sendTimeout="00:02:00"

             hostNameComparisonMode="StrongWildcard"
             maxBufferSize="524288" maxBufferPoolSize="524288" 
             maxReceivedMessageSize="524288"
             messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
             useDefaultWebProxy="true">

          </security>
       </binding>
     </basicHttpBinding>
   </bindings>
   <client>
      <endpoint name="BasicHttpBinding_IDatroseService" 
          address="http://localhost/DatroseWCFService/DatroseService.svc/svc" 
          behaviorConfiguration="DatroseServiceBehavior"
          binding="basicHttpBinding" 
          bindingConfiguration="BasicHttpBinding_IDatroseService"
          contract="DatroseWCFService.IDatroseService" />
   </client>
   <behaviors>
      <endpointBehaviors>
         <behavior name="DatroseServiceBehavior">
            <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
         </behavior>
      </endpointBehaviors>
   </behaviors>
</system.serviceModel>

当我运行它时，我现在收到 400(错误请求)错误。我不确定这是向前迈出的一步还是后退一步。我是否创建了一个新问题，或者是否为下一个问题扫清了道路？

根据 niao 的建议，我将服务器配置更改为:

<system.serviceModel>
    <services>
        <service name="GHMDatroseIntegration.GHMDatroseWCFService.DatroseService" behaviorConfiguration="DatroseServiceBehavior">
            <endpoint contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService" binding="basicHttpBinding" address="http://localhost/DatroseWCFService/DatroseService.svc"/>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="DatroseServiceBehavior">
                <!-- 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="true"/>
                <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

...然而，当我浏览到这个地址时，却出现了蓝屏死机:

Server Error in '/DatroseWCFService' Application.
When 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' is set to true in configuration, the endpoints are required to specify a relative address. If you are specifying a relative listen URI on the endpoint, then the address can be absolute. To fix this problem, specify a relative uri for endpoint 'http://localhost/DatroseWCFService/DatroseService.svc'.

...因此，我尝试将其设为如下所示的相对路径:

<endpoint 
   address="localhost/DatroseWCFService/DatroseService.svc"
   binding="basicHttpBinding" 
   contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService" />

...但是在发布之后，我收到了 404 错误。客户端端点配置如下:

<endpoint name="BasicHttpBinding_IDatroseService"
    address="http://localhost/DatroseWCFService/DatroseService.svc" 
    behaviorConfiguration="DatroseServiceBehavior"
    binding="basicHttpBinding" 
    bindingConfiguration="BasicHttpBinding_IDatroseService"
    contract="DatroseWCFService.IDatroseService"  />

更新 4 根据 marc_s 的建议，我从客户端删除了绑定(bind)配置，因此我的配置如下所示:

<system.serviceModel>
    <client>
        <endpoint address="http://localhost/DatroseWCFService/DatroseService.svc" behaviorConfiguration="DatroseServiceBehavior"
         binding="basicHttpBinding" 
         contract="DatroseWCFService.IDatroseService" name="BasicHttpBinding_IDatroseService" />
    </client>
    <behaviors>
        <endpointBehaviors>
            <behavior name="DatroseServiceBehavior">
                <dataContractSerializer maxItemsInObjectGraph="10000000"/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
</system.serviceModel>

我的服务器配置如下:

<system.serviceModel>
    <services>
        <service name="GHMDatroseIntegration.GHMDatroseWCFService.DatroseService" behaviorConfiguration="DatroseServiceBehavior">
            <endpoint contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService" binding="basicHttpBinding" address=""/>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="DatroseServiceBehavior">
                <serviceMetadata httpGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="true" httpsHelpPageEnabled="true" httpHelpPageEnabled="true"/>
                <dataContractSerializer maxItemsInObjectGraph="10000000"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

我不再收到 404 错误。

但是，我确实得到了一个 400(ProtocolException，错误的请求)，但没有关于它得到了什么或为什么它是错误的启发性信息。我希望我已经超越了端点问题，进入了一个全新的服务配置 hell 。

更新 5

根据请求，我的服务的“骨架”(我假设接口(interface)可以？):

[ServiceContract]
public interface IDatroseService
{

    [OperationContract]
    bool SubmitPayableTransaction(List<InvoiceItem> invoices);

    [OperationContract]
    Dictionary<string, bool> ValidateAccounts(List<string> accounts);

    [OperationContract]
    Dictionary<string, int> GetVendor1099Types(List<string> vendors);

    [OperationContract]
    Dictionary<string, string> GetPaymentTerms(List<string> vendors);

}

最佳答案

所以我假设您的服务托管在 IIS 中，对吗？

所以您的 *.svc 所在的虚拟目录基本上定义了您的服务地址 - 那么这个地址是否正确？

此外:您在服务端点上有“相对”地址 mex

<endpoint 
    address="mex"

(我认为这是一个非常糟糕的主意 - MEX 代表元数据交换，我不会将该地址用于常规服务端点!它只是违反了最少惊喜原则- 如果端点被调用 MEX ，我希望它成为元数据交换端点——而不是常规服务端点...)

无论如何 - 使用该常规地址，您的完整服务地址将变为:

http://yourserver/DatroseWCFService/DatroseService.svc/mex

如果您在该地址上调用您的服务会怎么样 - 您会得到响应吗？？

<罢工> 更新:不确定您是如何尝试测试的。这是一个 SOAP 网络服务 - 您将在浏览器中看到该服务的“登陆页面”(“帮助”页面)，但要测试该服务本身，您需要使用支持 SOAP 的测试工具(如 WCF Test Client 或SoapUI) - 您无法通过仅浏览其网址来测试 SOAP Web 服务。
(好的，所以您通过从测试应用程序调用服务来测试它 - 这绝对有效!)

更新#2:因为您在 IIS 中托管它(对吗？)，您的服务地址基本上由 *.svc 文件所在的虚拟目录定义。所以我的下一次尝试是:让那个地址成为您的服务地址。

将您的服务端配置更改为:

<service name="GHMDatroseIntegration.GHMDatroseWCFService.DatroseService" 
         behaviorConfiguration="DatroseServiceBehavior">
   <endpoint 
       address=""   <!-- define nothing here - just let the *.svc file determine your service address -->
       binding="basicHttpBinding" 
       contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService" />
   <endpoint 
       address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>

和您的客户端配置:

<endpoint name="BasicHttpBinding_IDatroseService"
    address="http://localhost/DatroseWCFService/DatroseService.svc" 
    behaviorConfiguration="DatroseServiceBehavior"
    binding="basicHttpBinding" 
    bindingConfiguration="BasicHttpBinding_IDatroseService"
    contract="DatroseWCFService.IDatroseService"  />

这样行吗？？

下一次尝试是使用没有 bindingConfiguration= 值的客户端配置 - 因为这也是你在服务器上所做的 - 绝对是没有 任何 修改的基本 basicHttpBinding -有用吗？？
