c# - c#中的肥皂请求和响应

Question

我为 Soap XML 请求编写了 c# 代码，我已经验证了此代码生成 XML 类。

我的问题是如何使用 c# 代码发送请求和接收响应。

请善待我的简单或基本错误，因为我是 XML 的新手，但非常感谢您的帮助。

SOAP XML 请求：

请您告诉我如何使用上述代码从 WCF 服务发送请求和接收响应。

即使我添加了 wsdl 引用，但我不知道如何在下面的行中传递 XmlElement[]。

serviceReference.getDetail(ref XmlElement[] Any);

这是参考类中的一个方法。

   [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    [System.ServiceModel.ServiceContractAttribute(Namespace="http://www.domainname.com/whatever/webname/schema/ce/v2.2/NameContractServic" +
        "e", ConfigurationName="TestingPension.NameContractServiceDetailType")]
    public interface NameContractServiceDetailType {

        // CODEGEN: Generating message contract since the wrapper namespace (http://www.domainname.com/schema/ce/v2.2/NameContractRequest) of message getDetailRequest does not match the default value (http://www.domainname.com/name/name/schema/ce/v2.2/NameContractService)
        [System.ServiceModel.OperationContractAttribute(Action="http://www.origostandards.com/schema/ce/v2.2/CEPensionSingleContract#getDetail", ReplyAction="*")]
        [System.ServiceModel.FaultContractAttribute(typeof(SoapReqResWebApplication.TestingPension.Error[]), Action="http://www.domainname.com/schema/ce/v2.2/NameContract#getDetail", Name="errors", Namespace="http://www.domainname.com/schema/tech/v1.0/SOAPFaultDetail")]
        [System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults=true)]
        SoapReqResWebApplication.TestingPension.getDetailResponse getDetail(SoapReqResWebApplication.TestingPension.getDetailRequest request);
    }

    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    [System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]
    [System.ServiceModel.MessageContractAttribute(WrapperName="message", WrapperNamespace="http://www.domainname.com/schema/ce/v2.2/NameContractRequest", IsWrapped=true)]
    public partial class getDetailRequest {

        [System.ServiceModel.MessageBodyMemberAttribute(Namespace="", Order=0)]
        [System.Xml.Serialization.XmlAnyElementAttribute()]
        public System.Xml.XmlElement[] Any;

        public getDetailRequest() {
        }

        public getDetailRequest(System.Xml.XmlElement[] Any) {
            this.Any = Any;
        }
    }

@CodeCaster我将您的代码尝试为： var documentToSend = new XmlDocument(); //// TODO: 添加你喜欢
使用的所有元素 (XmlTextWriter xmlRequestWriter = new XmlTextWriter(@"C:/Unipass/Request.xml", Encoding.UTF8)) { xmlRequestWriter.WriteStartDocument(); xmlRequestWriter.WriteStartElement("ce:message"); xmlRequestWriter.WriteEndElement(); xmlRequestWriter.WriteEndDocument(); xmlRequestWriter.Flush(); documentToSend.Save(xmlRequestWriter); //// 创建一个以根消息节点为唯一元素的数组。var xmlToSend = new XmlElement[] { documentToSend.DocumentElement }; //xmlToSend = null
可能是我做错了，请你告诉我为什么 xmlToSend 为空。

您似乎正在手动编写代码以将消息序列化为 SOAP/XML。SOAP 请求示例是一个实际的实例文档而不是 WSDL，是吗？这是 WCF 为您做的事情之一 - 您不需要生成自己的 SOAP 消息。

在 WCF 中，您专注于要传输的对象类型和要支持的操作。然后 WCF 为您完成所有繁重的 SOAP 序列化工作。这确实是 WCF 的重点。

很难从您的示例 SOAP 消息中解读您到底想要做什么，所以我建议您查看一个简单的 WCF 示例，例如从这里

http://msdn.microsoft.com/en-us/library/vstudio/ms751514(v=vs.90).aspx

使用 wsHttpBinding 或 basicHttpBinding（这些是 WCF 中的 SOAP 绑定）启动并运行一个简单的。然后使用 Fiddler 或类似工具捕获 HTTP 请求，并查看 WCF 在 SOAP 信封生成方面为您做了什么。

然后，您应该能够将其转化为您自己的案例。

鉴于生成的方法签名是getDetailRequest(System.Xml.XmlElement[] Any). SoapUI之类的工具对 WSDL 有什么看法？

解决这个问题的一种方法是确实手动生成消息，这只是<ce:message>..</ce:message>块。当您调用服务方法时，WCF 会将其包装在适当的 SOAP 信封中。

你必须在XmlDocument课堂上玩一点，但我认为这样的事情会做到这一点：

// Create an XmlDocument and fill it
var documentToSend = new XmlDocument();

// TODO: add all elements you like

// Create an array with the root message node as only element.
var xmlToSend = new XmlElement[] { documentToSend.DocumentElement };

// Call the service.
var response = serviceReference.getDetail(xmlToSend);

另一种方法是在 C# 中手动重新创建请求类，并在发送请求时将其实例填充并序列化为 XML。最终的方法是修复 XML，以便添加服务引用 (SvcUtil) 可以从服务的元数据生成类。

至于您的编辑，您不是将 XML 元素documentToSend写入，而是将它们写入文件。
