c# - 使用 WCF 服务 - 找不到默认端点元素

Question

我按照一些指南在我的 Windows 应用程序中使用 WCF 服务。 我的 WCF 服务适用于我的移动应用程序，但我无法让它在 Windows 应用程序上运行。

当我尝试运行代码时产生的错误是:

Could not find default endpoint element that references contract 'AllocationService.IAllocatingService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

调用网络服务方法:

    AllocationService.AllocatingServiceClient client = new AllocationService.AllocatingServiceClient();
    client.notifyZoneChanged(1);

网络服务端:

    [OperationContract]
    void notifyZoneChanged(int LocationID);

Web 服务的 web.config:

  <?xml version="1.0"?>
  <configuration>
    <connectionStrings>
      <add name="PCSDB" connectionString="Data Source=alj6d2eqa0.database.windows.net;Initial Catalog=StaffAllocatorDB;Persist Security Info=True;User ID=---;Password=---" providerName="System.Data.SqlClient" />
    </connectionStrings>

    <system.serviceModel>
      <services>
        <service name ="StaffAllocator.AllocatingService">
          <endpoint address="" behaviorConfiguration="AllocationBehavior" binding="webHttpBinding" bindingConfiguration="" contract="StaffAllocator.IAllocatingService">
          </endpoint>
        </service>
      </services>
      <behaviors>
        <serviceBehaviors>
          <behavior>
            <!-- 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="false"/>
          </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
          <behavior name="AllocationBehavior">
            <webHttp/>
          </behavior>
        </endpointBehaviors>
      </behaviors>
      <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    </system.serviceModel>
    <system.webServer>
      <modules runAllManagedModulesForAllRequests="true"/>
    </system.webServer>

  </configuration>

Windows 应用程序的 App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="PCSDB" connectionString="Data Source=alj6d2eqa0.database.windows.net;Initial Catalog=StaffAllocatorDB;Persist Security Info=True;User ID=---;Password=---" providerName="System.Data.SqlClient"/>

    <behaviors>
      <endpointBehaviors>
        <behavior name="AllocationBehavior">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <endpoint Name="Default"
              address="http://staffallocatingsystem.cloudapp.net/AllocatingService.svc"
              binding="webHttpBinding"
              behaviorConfiguration="AllocationBehavior"
              contract="AllocationService.IAllocatingService" />
  </system.serviceModel>
</configuration>

您的客户端配置缺少 <endpoint>定义连接位置的节点 - 因此您需要将其添加到您的配置中:

<system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="AllocationBehavior">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <client>
       <endpoint Name="Default"
                 address="http://yourserver/virtualweb/YourService.svc"
                 binding="webHttpBinding"
                 behaviorConfiguration="AllocationBehavior"
                 contract="AllocationService.IAllocatingService" />
    </client>
</system.serviceModel>

address=位置由托管服务器的服务器名称决定，IIS 虚拟目录是您的 *.svc文件存在，*.svc 的名称文件本身(包括扩展名)
