在1个端点,WCF,Mono中找不到客户端端点配置"*"

Question

嘿伙计们,

我正在尝试使用Mono从我的Ubuntu主机访问托管在虚拟机(Windows 7)上的Web服务.

我可以导入wdsl文件并生成服务引用.我从正确访问webservice的其他工作客户端复制了App.config.

当我尝试使用System连接到webservice时;

namespace MonoTest
{
class MainClass
{
    public static void Main (string[] args)
    {
        Console.WriteLine ("Hello World!");
        TestServer.Service1Client client = new TestServer.Service1Client("Test");
        Console.WriteLine(client.GetData(12));
        Console.ReadLine();
    }
}
}

我收到一个错误:

System.InvalidOperationException: Client endpoint configuration 'Test' was not found in 1 endpoints.
  at System.ServiceModel.ChannelFactory.ApplyConfiguration (System.String endpointConfig) [0x00000] in <filename unknown>:0 
  at System.ServiceModel.ChannelFactory.InitializeEndpoint (System.String endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) [0x00000] in <filename unknown>:0 
  at System.ServiceModel.ChannelFactory`1[MonoTest.TestServer.IService1]..ctor (System.String endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) [0x00000] in <filename unknown>:0 
  at System.ServiceModel.ClientBase`1[MonoTest.TestServer.IService1].Initialize (System.ServiceModel.InstanceContext instance, System.String endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) [0x00000] in <filename unknown>:0 
  at System.ServiceModel.ClientBase`1[MonoTest.TestServer.IService1]..ctor (System.ServiceModel.InstanceContext instance, System.String endpointConfigurationName) [0x00000] in <filename unknown>:0 
  at System.ServiceModel.ClientBase`1[MonoTest.TestServer.IService1]..ctor (System.String endpointConfigurationName) [0x00000] in <filename unknown>:0 
  at MonoTest.TestServer.Service1Client..ctor (System.String endpointConfigurationName) [0x00000] in <filename unknown>:0 
  at MonoTest.MainClass.Main (System.String[] args) [0x0000a] in /home/***/WebserviceTest/MonoTest/MonoTest/Main.cs:11 

我的App.config文件如下所示:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="WSHttpBinding_IService1" />
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint name="Test"
                address="http://192.168.178.34:8732/Design_Time_Addresses/TestServer/Service1/"
                binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService1"
                contract="ServiceReference1.IService1" >
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

有没有人使用Linux工作？

Mono的WSDL导入工具尚不支持自动配置生成,您需要手动配置端点app.config.

您在此处看到的错误意味着WCF无法找到端点配置部分.

问题的详细,技术原因

您得到这个是因为Visual Studio和Mono具有不同的,不兼容的引用配置部分的方式.

在Visual Studio中添加服务引用时,它会自动创建和更新您的相应条目app.config.生成的"合同名称" <endpoint ... contract="contract name">不一定是生成的数据合同类的完全限定名称Reference.cs.

相反,Visual Studio会发出

    [ServiceContractAttribute(ConfigurationName="contract name")]
    public interface YourContract {
            ....
    }

在ConfigurationName相同的<endpoint ... contract="...">元素,这是WCF如何找到端点配置.

在Mono,由于我们还不支持配置文件生成,我们发出

    [ServiceContractAttribute]
    public interface YourContract {
            ....
    }

如果没有ConfigurationName参数,则缺省值是该接口的完全限定名称.

如何解决您的问题

要使其工作,您需要编辑app.config文件并在<endpoint ... contract="...">元素中使用服务合同接口的完全限定名称.

在你的情况下,contract="ServiceReference1.IService1"改成contract="TestServer.IService1"应该这样做.

否则,查看生成的Reference.cs,搜索具有[ServiceContractAttribute]它所在的C#名称空间的接口.
