.NET Core - 找不到简单的肥皂请求代码

Question

我需要发送这样的xml

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:web="**************">
    <soap:Header/>
    <soap:Body>
        <web:Open>
            <web:username>USERNAME</web:username>
            <web:password>PASSWORD</web:password>
        </web:Open>
    </soap:Body>
</soap:Envelope>

来自本教程https://stackify.com/soap-net-core/

var binding = new BasicHttpBinding();
var endpoint = new EndpointAddress(new Uri("http://server/PingService.svc"));
var channelFactory = new ChannelFactory(binding, endpoint);
var serviceClient = channelFactory.CreateChannel();
var result = serviceClient.Ping("Ping");
channelFactory.Close();

但是如何修改此代码以执行我自己的请求？

我分析了有关 WCF 和 svcutils 的 microsoft 文档，它看起来非常复杂 我的意思是，所有这些，只是为了发送一个 XML？

我如何以最简单的方式发出 SOAP 请求？

感谢您在这方面帮助我

最简单的方法是将 wsdl 从服务器端导入到您的项目中。这将生成大部分所需的代码。您提出的与此相关的另一个问题中提供了一个示例。

也可以完全手动完成。首先，您需要创建一个或 2 个描述您的标头和有效负载的 xml 架构（标头是可选的）。

打开.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:web="http://bvdep.com/webservices/" targetNamespace="http://bvdep.com/webservices/" elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:complexType name="OpenType">
        <xs:sequence>
            <xs:element name="username" type="xs:string"/>
            <xs:element name="password" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
    <xs:element name="Open" type="web:OpenType"/>
</xs:schema>

header.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:head="http://bvdep.com/webservices/Header" targetNamespace="http://bvdep.com/webservices/Header" elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:element name="Header" type="head:HeaderType"/>
    <xs:complexType name="HeaderType">
        <xs:sequence>
            <xs:element name="From" type="xs:string"/>
            <xs:element name="To" type="xs:string"/>
            <xs:element name="MsgType" type="xs:string"/>
            <xs:element name="Datetime" type="xs:dateTime"/>
        </xs:sequence>
    </xs:complexType>
</xs:schema>

然后您使用 xsd.exe 生成类文件。我使用 bat 文件来执行此操作。

@echo off
set exepad=C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\xsd.exe
set sourcepad=..\..\

set xsdpad=%sourcepad%\ConsoleCore\xsd
set Outpad=%sourcepad%\ConsoleCore\generated

Set NameSpace=ConsoleCore.generated

"%exepad%" "%xsdpad%\Open.xsd" /c  /n:%NameSpace%  /o:%Outpad%
"%exepad%" "%xsdpad%\Header.xsd" /c  /n:%NameSpace%  /o:%Outpad%

在您的 vs 核心项目中，您需要添加 2 个 nuget 包 System.ServiceModel.Primitives 和 System.ServiceModel.Http

接下来，您需要添加一个接口来描述您想要调用的服务和操作，就像您在 ping 示例中找到的那样

[ServiceContract(Namespace = "http://Open.webservice.namespace")]
    public interface IOpenService
    {
        [XmlSerializerFormat()]
        [OperationContract(IsOneWay = false, Action = "urn:#OpenOperation")]
        OpenReturnMsg OpenOperation(OpenMsg msg);
    }

    [MessageContract(IsWrapped = false)]
    public class OpenMsg
    {
        [MessageHeader(Name = "Header", Namespace = "http://bvdep.com/webservices/Header")] public HeaderType Header { get; set; }
        [MessageBodyMember(Name = "Open", Namespace = "http://bvdep.com/webservices/")] public OpenType Open { get; set; }
    }

    [MessageContract(IsWrapped = false)]
    public class OpenReturnMsg
    {
        [MessageBodyMember(Name = "ResponseMsg", Namespace = "http://Open.webservice.namespace")] public string ResponseMsg { get; set; }
    }

最后是调用服务并获得响应的实际语句：

static void Main(string[] args)
        {
            Console.WriteLine("Start Program!");

            var binding = new BasicHttpBinding();
            var endpoint = new EndpointAddress(new Uri("http://LOCALHOST:8085/mockOpenBinding"));
            var channelFactory = new ChannelFactory<IOpenService>(binding, endpoint);
            var serviceClient = channelFactory.CreateChannel();


            var msg = new OpenMsg
            {
                Header = new HeaderType
                {
                    From = "source",
                    To = "dest",
                    MsgType = "open",
                    Datetime = DateTime.Now
                },
                Open = new OpenType
                {
                    username = "user",
                    password = "pw"
                }
            };

            var result = serviceClient.OpenOperation(msg);
            channelFactory.Close();
            Console.WriteLine(result.ResponseMsg);
        }

我已经在 SOAPUI 中使用来自以下 WSDL 的模拟服务对此进行了测试。
