【问题描述】:
具体来说,我有一个客户端应用程序,它将尝试调用将部署在多个 Web 服务器上的 Web 服务。 URI 列表将从客户端的 Settings.settings 文件中获取,foreach 循环将循环遍历 URI,直到可用服务响应。
假设我有以下合同的服务:
[ServiceContract]
public interface ICMMSManagerService
{
[OperationContract]
ServerInfo GetServerInfo(string systemNumber);
}
在服务项目的web.config中,我定义了CMMSManager服务,端点名称为:BasicHttpBinding_IWorkloadMngrService
<system.serviceModel>
<services>
<service name="WorkloadMngr">
<endpoint binding="basicHttpBinding" contract="IMetadataExchange" />
</service>
<service name="CMMSManager">
<endpoint binding="basicHttpBinding" contract="IMetadataExchange" name="BasicHttpBinding_IWorkloadMngrService" />
</service>
</services>
<client>
<remove contract="IMetadataExchange" name="sb" />
</client>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding>
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
在客户端,我在应用程序启动时执行了以下代码:
private void QueryWebServiceUrls()
{
var webServiceUrls = Properties.Settings.Default.WebServiceUrls;
foreach (var webServiceUrl in webServiceUrls)
{
try
{
var client = new CMMSManagerServiceClient("BasicHttpBinding_IWorkloadManagerService");
client.Endpoint.Address = new EndpointAddress(new Uri(webServiceUrl),
client.Endpoint.Address.Identity, client.Endpoint.Address.Headers);
client.Open();
var result = client.GetServerInfo("test");
}
catch (EndpointNotFoundException e)
{
continue;
}
catch (InvalidOperationException e)
{
break;
}
}
}
但是当CMMSManagerServiceClient 类被实例化时,应用程序会崩溃并显示InvalidOperationException。
找不到具有名称的端点元素 'BasicHttpBinding_IWorkloadMngrService' 和合同 ServiceModel 客户端中的“ComClientService.ICMMSManagerService” 配置部分。这可能是因为没有配置文件 为您的应用程序找到,或者因为没有匹配的端点元素 此名称可以在客户端元素中找到。
我在app.config中有如下配置:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_ICMMSManagerService">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost/WorkloadMngr/CMMSManagerService.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICMMSManagerService"
contract="ComClientService.ICMMSManagerService" name="BasicHttpBinding_ICMMSManagerService" />
</client>
</system.serviceModel>
我认为通过将BasicHttpBinding_ICMMSManagerService 参数传递给CMMSManagerServiceClient 类,一切都是有效的。我不知道我现在错过了什么......有什么想法吗?
