WCF无法找到端点配置问题

Jer*_*acs 3 c# configuration wcf wcf-binding wcf-client

我有一个WCF的web服务我在我的本地机器上测试,它给了我一个headscratcher.

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">

我收到的错误是:

在http://localhost/DatroseWCFService/DatroseService.svc上没有可以接受该消息的端点.这通常是由错误的地址或SOAP操作引起的.有关更多详细信息,请参阅InnerException(如果存在).

...然而,如果我浏览到我获得服务屏幕的位置,那么它似乎已正确设置.

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.这里有一些帮助.

UPDATE whups我输错了错误信息.现在已经修复了.

根据我认为在这些响应中建议的更新2我已将服务器配置更改为:

当我运行这个时,我现在得到一个400(错误的请求)错误.我不确定这是前进还是后退.我是否创建了一个新问题,还是让我清楚了解下一个问题？

更新3

根据niao的建议,我更改为服务器配置:

<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"/>

        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

...但是,当我浏览这个地址时,我得到了一个黄色的死亡屏幕:

'/ DatroseWCFService'应用程序中的服务器错误.
当'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled'在配置中设置为true时,端点需要指定相对地址.如果要在端点上指定相对侦听URI,则地址可以是绝对的.要解决此问题,请为端点"http://localhost/DatroseWCFService/DatroseService.svc"指定相对uri.

......所以,我试着把它变成一条相对的路径:

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

...但在发布之后,我收到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"

更新4 根据marc_s的建议,我从客户端删除了绑定配置,所以我的配置如下所示:

<system.serviceModel>
    <client>
        <endpoint address="http://localhost/DatroseWCFService/DatroseService.svc" behaviorConfiguration="DatroseServiceBehavior"
         binding="basicHttpBinding"

            <endpoint contract="GHMDatroseIntegration.GHMDatroseWCFService.IDatroseService" binding="basicHttpBinding" address=""/>

我不再收到404错误.

但是,我确实得到了一个400(ProtocolException,Bad Request),没有任何关于它得到的信息或为什么它不好的信息.我希望我已经超越了端点问题,进入了全新的服务配置空间.

更新5

每个请求,我的服务的"骨架"(我假设接口会这样做？):

[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);

}

所以我假设您的服务是在IIS内托管的,对吧？

那么你的*.svc生活基本上定义了服务地址的虚拟目录- 这个地址是否正确？

另外:您mex在服务端点上有"相对"地址

<endpoint 
    address="mex"

Run Code Online (Sandbox Code Playgroud)

(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!它只是违反了最低惊喜原则 - 如果端点被调用 MEX,我希望它是一个元数据交换端点 - 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

Run Code Online (Sandbox Code Playgroud)

如果您在该地址上拨打您的服务怎么办？您会收到回复吗？

更新:不确定您是如何尝试测试的.这是一个SOAP Web服务 - 您将在浏览器中看到服务的"登录页面"("帮助"页面),但是要测试服务本身,您需要使用支持SOAP的测试工具(如WCF测试)客户端或SoapUI) - 您无法通过浏览其Web地址来测试SOAP Web服务.
(好吧,所以你通过从测试应用程序调用服务来测试它 - 这应该绝对有效!)

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:只需将该地址作为您的服务地址即可.

将服务端配置更改为:

<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>

Run Code Online (Sandbox Code Playgroud)

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"  />

那样有用吗？？

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事情 - 只是绝对basicHttpBinding没有任何修改的裸机- 这有用吗？
