c# - 如何从POSTMAN调用WCF服务方法

Question

我正在尝试使用 WCF 端点调用服务。 WCF 服务托管在 Windows 服务上，

这是配置。

          <!-- 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

    </protocolMapping>

  </system.serviceModel>
</configuration>

我们尝试使用 POSTMAN 调用该服务，如下所示:

这是原始主体:

<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>

但是，我们收到了这个回复

<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>

内容类型标题为text/xml。

我们正在尝试使用 POST

Answer 1

1. 运行您的 WCF。例如https://learn.microsoft.com/en-us/dotnet/framework/wcf/getting-started-tutorial

2. 打开wsdl并找到Action

3. 您还可以在 WCF 测试客户端中找到 Action
4. 在 postman 中 URL - 来自 wsdl - http://localhost:8000/GettingStarted/CalculatorService/

标题 -

内容类型:text/xml

SOAPAction:http://Microsoft.ServiceModel.Samples/ICalculator/Add 4. 从 WCF 测试客户端添加主体。 对我来说， body 是

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> 
  <s:Body>
    <Add xmlns="http://Microsoft.ServiceModel.Samples">
      <n1>1</n1>
      <n2>1</n2>
    </Add>
  </s:Body>
</s:Envelope>

在下拉菜单中选择 - xml 发送
