Como: Exportar metadados de pontos de extremidade de serviço

  • Artigo

Este tópico explica como exportar metadados de pontos de extremidade de serviço.

Para exportar metadados de pontos de extremidade de serviço

  1. Crie um novo projeto de aplicativo de console do Visual Studio. Adicione o código mostrado nas etapas a seguir no arquivo de Program.cs gerado dentro do método main().

  2. Crie um WsdlExporterarquivo .

    WsdlExporter exporter = new WsdlExporter();

    Dim exporter As New WsdlExporter()

  3. Defina a PolicyVersion propriedade como um dos valores da PolicyVersion enumeração. Este exemplo define o valor ao qual corresponde ao Policy15 WS-Policy 1.5.

    exporter.PolicyVersion = PolicyVersion.Policy15;

    exporter.PolicyVersion = PolicyVersion.Policy15

  4. Crie uma matriz de ServiceEndpoint objetos.

    ServiceEndpoint [] myServiceEndpoints = new ServiceEndpoint[2];
ContractDescription myDescription = new ContractDescription ("myContract");
myServiceEndpoints[0] = new ServiceEndpoint(myDescription,new BasicHttpBinding(),new EndpointAddress("http://localhost/myservice"));
myServiceEndpoints[1] = new ServiceEndpoint(myDescription,new BasicHttpBinding(),new EndpointAddress("http://localhost/myservice"));

    Dim myServiceEndpoints() As ServiceEndpoint = New ServiceEndpoint(1) {}
Dim myDescription As New ContractDescription("myContract")
myServiceEndpoints(0) = New ServiceEndpoint(myDescription, New BasicHttpBinding(), New EndpointAddress("http://localhost/myservice"))
myServiceEndpoints(1) = New ServiceEndpoint(myDescription, New BasicHttpBinding(), New EndpointAddress("http://localhost/myservice"))

  5. Exporte metadados para cada ponto de extremidade de serviço.

    // Export all endpoints for each endpoint in collection.
foreach (ServiceEndpoint endpoint in myServiceEndpoints)
{
    exporter.ExportEndpoint(endpoint);
}

    'Export all endpoints for each endpoint in collection.
For Each endpoint As ServiceEndpoint In myServiceEndpoints
    exporter.ExportEndpoint(endpoint)
Next

  6. Verifique se não ocorreram erros durante o processo de exportação e recupere os metadados.

    // If there are no errors, get the documents.
MetadataSet metadataDocs = null;
if (exporter.Errors.Count != 0)
{
    metadataDocs = exporter.GetGeneratedMetadata();
}

    'If there are no errors, get the documents.
Dim metadataDocs As MetadataSet
metadataDocs = Nothing

If (exporter.Errors.Count = 0) Then
    metadataDocs = exporter.GetGeneratedMetadata()
End If

  7. Agora você pode usar os metadados, como gravá-los em um arquivo chamando o WriteTo(XmlWriter) método.

Exemplo

A seguir está a lista de código completo para este exemplo.

using System;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace WsdlExporterSample
{
    class Program
    {
        static void Main(string[] args)
        {
            WsdlExporter exporter = new WsdlExporter();
            exporter.PolicyVersion = PolicyVersion.Policy15;

            ServiceEndpoint [] myServiceEndpoints = new ServiceEndpoint[2];
            ContractDescription myDescription = new ContractDescription ("myContract");
            myServiceEndpoints[0] = new ServiceEndpoint(myDescription,new BasicHttpBinding(),new EndpointAddress("http://localhost/myservice"));
            myServiceEndpoints[1] = new ServiceEndpoint(myDescription,new BasicHttpBinding(),new EndpointAddress("http://localhost/myservice"));

            // Export all endpoints for each endpoint in collection.
            foreach (ServiceEndpoint endpoint in myServiceEndpoints)
            {
                exporter.ExportEndpoint(endpoint);
            }
            // If there are no errors, get the documents.
            MetadataSet metadataDocs = null;
            if (exporter.Errors.Count != 0)
            {
                metadataDocs = exporter.GetGeneratedMetadata();
            }
        }
    }
}

Imports System.ServiceModel
Imports System.ServiceModel.Description

Module Module1

    Sub Main()
        Dim exporter As New WsdlExporter()
        exporter.PolicyVersion = PolicyVersion.Policy15

        Dim myServiceEndpoints() As ServiceEndpoint = New ServiceEndpoint(1) {}
        Dim myDescription As New ContractDescription("myContract")
        myServiceEndpoints(0) = New ServiceEndpoint(myDescription, New BasicHttpBinding(), New EndpointAddress("http://localhost/myservice"))
        myServiceEndpoints(1) = New ServiceEndpoint(myDescription, New BasicHttpBinding(), New EndpointAddress("http://localhost/myservice"))

        'Export all endpoints for each endpoint in collection.
        For Each endpoint As ServiceEndpoint In myServiceEndpoints
            exporter.ExportEndpoint(endpoint)
        Next

        'If there are no errors, get the documents.
        Dim metadataDocs As MetadataSet
        metadataDocs = Nothing

        If (exporter.Errors.Count = 0) Then
            metadataDocs = exporter.GetGeneratedMetadata()
        End If
    End Sub

End Module

Compilando o código

Ao compilar Program.cs referência System.ServiceModel.dll.
