将ASMX Web服务元数据导入WCF端点

Question

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.

在这篇文章之后,我能够获得远程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.

我有一套用于审查这个问题的米老鼠解决方案.

我的Asmx解决方案包含一个默认的"Hello World"Web服务,如下所示

[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.任何帮助将非常感激,

谢谢!

注意:MetadataSet metaSet = mexClient.GetMetadata();上面调用时生成的错误是System.InvalidOperationException带有消息的

元数据包含无法解析的引用:' http:// localhost:1803/SimpleAsmxService.asmx？WSDL '

用System.InvalidOperationException与消息内部异常

<?xml version="1.0" encoding="utf-16"?>
<Fault xmlns="http://www.w3.org/2003/05/soap-envelope">
    <Code>
        <Value>Sender</Value>

Answer 1

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);
...

使用MetadataExchangeClientMode.HttpGet用于ASMX服务和MetadataExchangeClientMode.用于WCF服务的MetadataExchange.
