我感兴趣的是冒充知名的Web服务和Wcf服务进行集成测试。为此,我想在自托管环境中捕获服务元数据,自动生成服务存根和主机服务存根。
在this article here之后,我能够获取远程Wcf服务元数据并生成合同。但是,我在为远程Asmx Web服务做同样的事情时遇到了一些困难。
我有一套米老鼠解决方案来审核这个问题。
我的Asmx解决方案包含一个默认的“Hello World”Web服务,位于
下面[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class SimpleAsmxService : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld () { return "Hello World"; }
}
我的Wcf解决方案包含默认的“Hello World”服务,也可以在
下面找到[ServiceContract]
public interface ISimpleWcfService
{
[OperationContract]
string GetData(int value);
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
}
[DataContract]
public class CompositeType
{
[DataMember]
public bool BoolValue { get; set; }
[DataMember]
public string StringValue { get; set; }
}
public class SimpleWcfService : ISimpleWcfService
{
public string GetData(int value)
{
return string.Format("You entered: {0}", value);
}
public CompositeType GetDataUsingDataContract(CompositeType composite)
{
if (composite.BoolValue)
{
composite.StringValue += "Suffix";
}
return composite;
}
}
最后,小控制台 - 看起来像
class Program
{
public const string UrlWcf =
"http://localhost:8731/Design_Time_Addresses/SimpleWcfService/mex";
public const string UrlAsmx =
"http://localhost:1803/SimpleAsmxService.asmx?WSDL";
static void Main(string[] args)
{
EndpointAddress mexAddress = new EndpointAddress (UrlWcf);
MetadataExchangeClient mexClient =
new MetadataExchangeClient (mexAddress);
mexClient.ResolveMetadataReferences = true;
// NOTE: blows up if we use UrlAsmx
MetadataSet metaSet = mexClient.GetMetadata ();
WsdlImporter importer = new WsdlImporter (metaSet);
Collection<ContractDescription> contracts =
importer.ImportAllContracts();
}
}
在我看来,我应该能够从着名的Asmx Web服务中提取Wsdl并生成合同[并从合同到代码],但似乎无法扭曲前面的示例。任何帮助将不胜感激,
谢谢!
注意:上面调用MetadataSet metaSet = mexClient.GetMetadata();
时产生的错误是System.InvalidOperationException
,消息为
元数据包含无法解析的引用:“http://localhost:1803/SimpleAsmxService.asmx?WSDL”
System.InvalidOperationException
内部异常,消息为

答案 0 :(得分:6)
使其与ASMX Web服务一起使用的方法是指定 MetadataExchangeClientMode
...
MetadataExchangeClient mexClient =
new MetadataExchangeClient (new Uri(), MetadataExchangeClientMode.HttpGet);
...
为您的ASMX服务使用 MetadataExchangeClientMode 。 HttpGet 和 MetadataExchangeClientMode 。 MetadataExchange ,用于您的WCF服务。
