从微服务c#调用wsdl服务

Question

如何在微服务内的 C# 和 ASP.NET Core 6.0 中在运行时调用 WSDL 服务？

我尝试过

HttpClient

，其他解决方案，如通道工厂，但他们没有解决问题。

private static async Task LlamadaServicioAsync()
{
    string wsdlUrl = "http://localhost/SCTSBJAX/ServiciosVEXJx?wsdl";
    string operationName = "ConsultarSaldosCobros";
    string soapAction = "http://localhost:7031/ConsultarSaldosCobros/";
    string requestBody = "<cce:ConsultaCobroReq><sesionReq><sesionId>57301</sesionId><userId>8</userId><hashSesion>008B5AAD0643AE56C721CDF71AFE7D82A04F6C95031B650EA888FD7D512E9C95</hashSesion><codTran>1</codTran><codigoCanal>1</codigoCanal></sesionReq><servicioAdq><codigoEmpresaAdq>1</codigoEmpresaAdq><codigoAplicacionAdq>VEX</codigoAplicacionAdq><codigoServicioAdq>6</codigoServicioAdq><codigoCanalAdq>1201</codigoCanalAdq><referenciaAdquiriente>54214089</referenciaAdquiriente><fechaAdquiriente>2016-02-20T09:56:29-05:00</fechaAdquiriente><codigoComercio>0990858322001PG041</codigoComercio><codigoTerminal>123</codigoTerminal></servicioAdq><productoReq><codigoInstitucion>408</codigoInstitucion><codAplProducto>SER</codAplProducto><codigoProducto>386</codigoProducto><camposAdicionales>\"{\"campos\\\":[{\"codigo\":\"Tipo Identificacion\",\"valor\":\"CEDULA\",\"requerido\":\"M\"},{\"codigo\":\"Identificacion\",\"valor\":\"1304837162\",\"requerido\":\"M\"}]}\"</camposAdicionales></productoReq><codigoInstitucionAut>406</codigoInstitucionAut></cce:ConsultaCobroReq></cce:ConsultarSaldosCobro>";

    await CallWebService(wsdlUrl, operationName, soapAction, requestBody);
}

public static async Task CallWebService(string wsdlUrl, string operationName, string soapAction, string requestBody)
{
    // Download the WSDL file
    string wsdl = await DownloadWsdl(wsdlUrl);

    // Create a binding and endpoint address
    BasicHttpBinding binding = new BasicHttpBinding();
    EndpointAddress endpointAddress = new EndpointAddress(wsdlUrl);

    // Create a channel factory
    ChannelFactory<IClientChannel> factory = new ChannelFactory<IClientChannel>(binding, endpointAddress);

    // Create a message
    Message requestMessage = Message.CreateMessage(MessageVersion.Soap11, soapAction, new StringReader(requestBody));

    // Create a channel
    IClientChannel channel = factory.CreateChannel();

    try
    {
        // Open the channel
        channel.Open();

        // Send the request and get the response
        Message responseMessage = await channel.RequestAsync(requestMessage);

        // Process the response
        using (XmlReader reader = responseMessage.GetReaderAtBodyContents())
        {
            // Read the response body
            XmlDocument responseXml = new XmlDocument();
            responseXml.Load(reader);

            // Process the response XML as needed
            Console.WriteLine(responseXml.OuterXml);
        }
    }
    finally
    {
        // Close the channel
        if (channel.State == CommunicationState.Faulted)
        {
            channel.Abort();
        }
        else
        {
            channel.Close();
        }

        // Close the factory
        factory.Close();
    }
}

实际上我有一个肥皂服务有一个方法

ConsultarSaldosCobros

和一个请求，我需要在执行时调用。如果我添加服务引用，它可以正常工作，但是地址站点会根据环境而变化，因此我需要使用环境变量作为地址，执行时读取变量并调用方法。

代码是：

string direccion = Environment.GetEnvironmentVariable(StringHandler.LOGIN_URL);

  using HttpContent content = new StringContent(text, Encoding.UTF8, "text/xml");
  using HttpRequestMessage request = new(HttpMethod.Post, direccion);
  request.Headers.Add("SOAPAction", direccion);
  request.Content = content;
  using HttpResponseMessage response = await httpClient.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);
  string respuesta  = await response.Content.ReadAsStringAsync();
