c# WCF全局命名空间-皇家邮政

本文关键字：皇家 命名空间 WCF 全局 | 更新日期: 2023-09-27 18:04:33

我有一个正在生成请求的WCF SOAP客户机。该请求被服务器视为无效请求而拒绝。我已经使用SOAPUI跟踪到名称空间，但不知道如何让客户机产生所需的结果。

客户端作为web服务引用从wsdl生成，并生成以下SOAP消息;

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header></s:Header>
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <createShipmentRequest xmlns="http://www.royalmailgroup.com/api/ship/V2">
      <integrationHeader>
        <dateTime xmlns="http://www.royalmailgroup.com/integration/core/V1">2015-07-23</dateTime>
        <version xmlns="http://www.royalmailgroup.com/integration/core/V1">2</version>
        <identification xmlns="http://www.royalmailgroup.com/integration/core/V1">
          <applicationId>some random number</applicationId>
          <transactionId>some reference number</transactionId>
        </identification>
      </integrationHeader>
    </createShipmentRequest>
  </s:Body>
</s:Envelope>

如您所见，名称空间被输出到各个元素上…

我的工作示例具有在SOAP信封中定义的名称空间;

<s:Envelope xmlns:v2="http://www.royalmailgroup.com/api/ship/V2" xmlns:v1="http://www.royalmailgroup.com/integration/core/V1" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
  <s:Header></s:Header>
  <s:Body>
    <v2:createShipmentRequest>
      <v2:integrationHeader>
        <v1:dateTime>2015-07-23</v1:dateTime>
        <v1:version>2</v1:version>
        <v1:identification>
          <v1:applicationId>some random number</v1:applicationId>
          <v1:transactionId>some reference number</v1:transactionId>
        </v1:identification>
      </v2:integrationHeader>
    </v2:createShipmentRequest>
  </s:Body>
</s:Envelope>

从我的理解，这应该没有什么不同，但服务器只是拒绝请求。在SOAPUI中修改了生成的请求后，这显然会导致问题，那么我如何移动两个名称空间定义v1 &v2到SOAP信封，然后让正确的元素使用正确的前缀?

我的客户端使用以下函数启动;

private shippingAPIPortTypeClient GetProxy() {
  BasicHttpBinding myBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
  myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
  shippingClient = new shippingAPIPortTypeClient(myBinding, new EndpointAddress(new Uri(shippingClientSandboxEndpoint), EndpointIdentity.CreateDnsIdentity("api.royalmail.com"), new AddressHeaderCollection()));
  shippingClient.ClientCredentials.ClientCertificate.Certificate = certificate;
  return shippingClient;
}

所以我需要创建一个自定义MessageFormatter并将其作为行为附加到客户端操作。

对于其他需要这样做的人，你需要3个文件;

首先创建一个实现message的自定义消息类。在OnWriteStartEnvelope方法中，你可以在信封中添加/定义你想要的命名空间。

class RoyalMailMessage: Message {
  private readonly Message message;
  public RoyalMailMessage(Message message) {
    this.message = message;
  }
  public override MessageHeaders Headers {
    get {
      return this.message.Headers;
    }
  }
  public override MessageProperties Properties {
    get {
      return this.message.Properties;
    }
  }
  public override MessageVersion Version {
    get {
      return this.message.Version;
    }
  }
  protected override void OnWriteStartBody(XmlDictionaryWriter writer) {
    writer.WriteStartElement("Body", "http://schemas.xmlsoap.org/soap/envelope/");
  }
  protected override void OnWriteBodyContents(XmlDictionaryWriter writer) {
    this.message.WriteBodyContents(writer);
  }
  protected override void OnWriteStartEnvelope(XmlDictionaryWriter writer) {
    writer.WriteStartElement("s", "Envelope", "http://schemas.xmlsoap.org/soap/envelope/");
    writer.WriteAttributeString("xmlns", "v2", null, "http://www.royalmailgroup.com/api/ship/V2");
    writer.WriteAttributeString("xmlns", "v1", null, "http://www.royalmailgroup.com/integration/core/V1");
    writer.WriteAttributeString("xmlns", "xsi", null, "http://www.w3.org/2001/XMLSchema-instance");
    writer.WriteAttributeString("xmlns", "xsd", null, "http://www.w3.org/2001/XMLSchema");
  }
}

然后创建一个实现IClientMessageFormatter的自定义类。这使用了我们在上面为客户机发出的传出请求定义的Message类;

public class RoyalMailMessageFormatter: IClientMessageFormatter {
  private readonly IClientMessageFormatter formatter;
  public RoyalMailMessageFormatter(IClientMessageFormatter formatter) {
    this.formatter = formatter;
  }
  public object DeserializeReply(Message message, object[] parameters) {
    return this.formatter.DeserializeReply(message, parameters);
  }
  public Message SerializeRequest(MessageVersion messageVersion, object[] parameters) {
    var message = this.formatter.SerializeRequest(messageVersion, parameters);
    return new RoyalMailMessage(message);
  }
}
然后我们需要创建一个实现IOperationBehavior的自定义类。这是必需的，因此我们可以将自定义消息格式化程序作为一种行为附加到服务操作; 
class RoyalMailIEndpointBehavior: IOperationBehavior {
  public RoyalMailIEndpointBehavior() {}
  public void ApplyClientBehavior(OperationDescription description, ClientOperation proxy) {
    IClientMessageFormatter currentFormatter = proxy.Formatter;
    proxy.Formatter = new RoyalMailMessageFormatter(currentFormatter);
  }
  public void AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters) {
  }
  public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation) {
  }
  public void Validate(OperationDescription operationDescription) {
  }
}

最后，我们需要将自定义IOperation行为添加到WCF生成的所有服务操作中;

private shippingAPIPortTypeClient GetProxy() {
  BasicHttpBinding myBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
  myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate;
  shippingClient = new shippingAPIPortTypeClient(myBinding, new EndpointAddress(new Uri(shippingClientSandboxEndpoint), EndpointIdentity.CreateDnsIdentity("api.royalmail.com"), new AddressHeaderCollection()));
  shippingClient.ClientCredentials.ClientCertificate.Certificate = certificate;
  foreach(OperationDescription od in shippingClient.Endpoint.Contract.Operations) {
    od.Behaviors.Add(new RoyalMailIEndpointBehavior());
  }
  return shippingClient;
}

名称空间现在应该在SOAP信封中，并且元素都使用正确的前缀，例如;

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v2="http://www.royalmailgroup.com/api/ship/V2" xmlns:v1="http://www.royalmailgroup.com/integration/core/V1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <s:Header></s:Header>
  <s:Body>
    <v2:createShipmentRequest>
      <v2:integrationHeader>
        <v1:dateTime>2015-07-23T20:37:07.937+01:00</v1:dateTime>
        <v1:version>2</v1:version>
        <v1:identification>
          <v1:applicationId>SOME RANDOM ID</v1:applicationId>
          <v1:transactionId>SOME RANDOM ID</v1:transactionId>
        </v1:identification>
      </v2:integrationHeader>
    </v2:createShipmentRequest>
  </s:Body>
</s:Envelope>
