Question

尝试将WCF测试客户端与我的WCF服务一起使用时出现错误。这是服务代码：

[ServiceContract]
public interface IEmployeeService
{
    [OperationContract(Name = "GetEmployee")]
    [WebGet(RequestFormat = WebMessageFormat.Xml,
        UriTemplate = "/Employees/{employeeNumber}")]
    Employee GetEmployee(string employeeNumber);
}

public Employee GetEmployee(string employeeNumber)
{
    var employeeNumberValue = Convert.ToInt32(employeeNumber);
    var employee = DataProvider.GetEmployee(employeeNumberValue);
    return employee;
}

<system.serviceModel>
    <services>
        <service name="Employees.Services.EmployeeService"
                 behaviorConfiguration="metaBehavior">
            <endpoint address=""
                      behaviorConfiguration="webHttp"
                      binding="webHttpBinding"
                      contract="Employees.Services.IEmployeeService">
            </endpoint>
            <endpoint address="mex"
                      binding="mexHttpBinding"
                      contract="IMetadataExchange">
            </endpoint>
        </service>
    </services>
    <behaviors>
        <endpointBehaviors>
            <behavior name="webHttp">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
        <serviceBehaviors>
            <behavior name="metaBehavior">
                <serviceMetadata httpGetEnabled="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
</system.serviceModel>

我可以使用WCF测试客户端连接到服务，但是当我尝试调用GetEmployee（employeeNumber）时，我收到以下错误：

无法调用该服务。可能的原因：服务离线或无法访问;客户端配置与代理不匹配;现有代理无效。有关更多详细信息，请参阅堆栈跟踪。您可以尝试通过启动新代理，还原到默认配置或刷新服务来进行恢复。

我能够通过从浏览器发送请求来成功调用此服务。

知道为什么我不能使用WCF测试客户端吗？

Answer 1

请忽略我之前的回答。我认为问题不在于客户端配置。

请参阅WCF Test Client and WebHttpBinding。

这是网络的限制编程模型本身。与SOAP不同端点（即那些有端点的端点） BasicHttpBinding，WSHttpBinding等）哪种方法可以公开元数据关于自己（WSDL或Mex）有关所有操作的信息/ 有端点的参数目前没有标准的曝光方式非SOAP端点的元数据 - 和那正是如此基于webHttpBinding的端点是。在简而言之，WCF测试客户端不会对基于Web的端点很有用。如果代表的一些标准 WCF时会出现Web样式的端点发布它的下一个版本，我们很可能更新测试客户端以支持它，但目前还没有广泛的通过。

我认为你的配置错了，你应该添加node security mode =“None”和属性bindingConfiguration =“NoneSecurity”

更改为我的配置，请再试一次：

<system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="NoneSecurity"
          maxBufferPoolSize="12000000" maxReceivedMessageSize="12000000" useDefaultWebProxy="false">
          <readerQuotas maxStringContentLength="12000000" maxArrayLength="12000000"/>
          <security mode="None"/>
        </binding>
      </wsHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="Elong.GlobalHotel.Host.IHotelAPIBehavior"
        name="Elong.GlobalHotel.Host.IHotelAPI">
        <endpoint address="" binding="wsHttpBinding" bindingConfiguration="NoneSecurity" contract="Elong.GlobalHotel.Host.IIHotelAPI">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Elong.GlobalHotel.Host.IHotelAPIBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

  I had a similar problem, the solution was in a minor error in the message alias ... that very generic message ... in our case was assigned a Boolean false if the right is true.
  This value was in the MDM application that was running on websphere.

我案例中的路径：

   /opt/infamdm/hub/server/resources/cmxserver.properties
