How to call WCF service method from POSTMAN


I am trying to call a service using WCF endpoint. The WCF service is hosted on a Windows Service,

This is the config.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.diagnostics>  
    <sources>
      <source name="System.ServiceModel" propagateActivity="true" switchValue="All">
        <listeners>

        </listeners>
      </source>
      <source name="System.ServiceModel.MessageLogging" switchValue="All">
        <listeners>
          <add name="xmlTraceListener" />
        </listeners>
      </source>
    </sources>
    <sharedListeners>
      <add name="xmlTraceListener"
           type="System.Diagnostics.XmlWriterTraceListener"
           initializeData="C:\logwcf\Service.svclog" />
    </sharedListeners>
  </system.diagnostics>

          </filters>

      </diagnostics>

          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <services>
      <service name="xx.ServicioDistribucion.AnalisisDatos.Servicios.CuentasCobrar" behaviorConfiguration="behaviorDistribucion">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Hostware" contract="xx.ServicioDistribucion.AnalisisDatos.Interfaces.ICuentasCobrar">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://xx.143.46.82:8733/xx.ServicioDistribucion.AnalisisDatos.Servicios.CuentasCobrar/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="behaviorDistribucion">
          <serviceThrottling maxConcurrentSessions="10000"/>
          <!-- To avoid disclosing metadata information, 
          set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="True"/>
          <!-- To receive exception details in faults for debugging purposes, 
          set the value below to true.  Set to false before deployment 
          to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
<!--<dataContractSerializer maxItemsInObjectGraph="2147483646"/>-->
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https"/>
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
</configuration>

And we are trying to call the service with POSTMAN like this:

This is the raw body:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
   <soapenv:Header/>
   <soapenv:Body>
      <tem:ProcesarListaCuentasCobrarCIA100/>
   </soapenv:Body>
</soapenv:Envelope>

But, we are getting this response

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <s:Fault>
            <faultcode xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:DestinationUnreachable</faultcode>
            <faultstring xml:lang="es-CO">The message with To 'http://xx.143.46.82:8733/xxServicioDistribucion.AnalisisDatos.Servicios.CuentasCobrar/ProcesarListaCuentasCobrarCIA100/' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher.  Check that the sender and receiver's EndpointAddresses agree.</faultstring>
        </s:Fault>
    </s:Body>
</s:Envelope>

Content type heaer is text/xml.

and we are trying to use a POST


Solution

  • IIRC when you make SOAP calls to a WCF server, there are HTTP headers that have to be set in addition to the body content.

    My old SOAP calls have headers of the form:

    SOAPAction: http://domain/EndPoint
    

    You may need to check this. If you have a working client, capture the traffic with Fiddler. Also, I have the content-type set to "text/xml; charset=utf-8" and I seem to recall that some servers are picky about the content-type on POST.
