C# Soap 1.2 WebService

Question

我在调用外部第三方 SOAP Web 服务时遇到问题：我得到的错误是"远程服务器返回错误：(500( 内部服务器错误"。(来自客户端(，但问题是当我使用 SoapUI 5.4.0(在同一用户下的同一台 PC 上(调用时，它运行良好。该代码适用于任何其他 Web 服务。

有人可以给我任何想法吗？

using System;
using System.IO;
using System.Net;
using System.Xml;
namespace ConsoleApp1
{
class Program
/// Soap WebService call
    public static void Execute()
    {
        HttpWebRequest request = CreateWebRequest();
        request.Credentials = CredentialCache.DefaultCredentials;
        XmlDocument soapEnvelopeXml = new XmlDocument();
        NewMethod(soapEnvelopeXml);
        using (Stream stream = request.GetRequestStream())
        {
            soapEnvelopeXml.Save(stream);
        }
        using (WebResponse response = request.GetResponse())
        {
            Console.WriteLine(((HttpWebResponse)response).StatusDescription);
            using (StreamReader rd = new StreamReader(response.GetResponseStream()))
            {
                string soapResult = rd.ReadToEnd();
                Console.WriteLine(soapResult);
                Console.WriteLine("Done!");
                Console.ReadKey();
            }
        }
    }
    private static void NewMethod(XmlDocument soapEnvelopeXml)
    {
            soapEnvelopeXml.LoadXml(xml: @"<soap:Envelope xmlns:soap=""http://www.w3.org/2003/05/soap-envelope"" xmlns:out=""http://www.test.com/test/Services/Outage""><soap:Header/><soap:Body><out:GetLocations/></soap:Body></soap:Envelope>");
    }

    /// Create a soap webrequest to [Url]
    public static HttpWebRequest CreateWebRequest()
    {
         HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://test:557/OutageService.svc");
        webRequest.ContentType = @"application/soap+xml;charset=UTF-8";
        webRequest.Accept = "text/xml";
        webRequest.Method = "POST";
        return webRequest;
    }
    static void Main(string[] args)
    {
        Execute();
    }
 }
}

谢谢你@Broom！我已经使用提琴手做了一些测试，我得到以下消息：

          <s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope"   xmlns:a="http://www.w3.org/2005/08/addressing"><s:Header>
<a:Action s:mustUnderstand="1">http://www.w3.org/2005/08/addressing/fault</a:Action></s:Header><s:Body><s:Fault><s:Code><s:Value>s:Sender
 </s:Value><s:Subcode><s:Value>                                                  
   a:ActionMismatch</s:Value></s:Subcode></s:Code><s:Reason><s:Text  xml:lang="en-US">
 The SOAP action specified on the       message, '"http://www.test.com/test/Services/Outage/IOutageService/GetLocations"',
   does not match the HTTP SOAP Action, 'http://www.test.com/test/Services/Outage/IOutageService/GetLocations'. 
 </s:Text></s:Reason><s:Detail><a:ProblemHeaderQName>a:Action</a:ProblemHeaderQName></s:Detail></s:Fault></s:Body></s:Envelope>

所以在我的代码中我改变了

private static void NewMethod(XmlDocument soapEnvelopeXml)
{
        soapEnvelopeXml.LoadXml(xml: @"<soap:Envelope xmlns:soap=""http://www.w3.org/2003/05/soap-envelope"" xmlns:out=""http://www.test.com/test/Services/Outage""><soap:Header/><soap:Body><out:GetLocations/></soap:Body></soap:Envelope>");
}

到以下

soapEnvelopeXml.LoadXml(xml: @"<soap:Envelope xmlns:soap=""http://www.w3.org/2003/05/soap-envelope"" xmlns:out=""http://www.test.com/test/Services/Outage""><soap:Header xmlns:wsa=""http://www.w3.org/2005/08/addressing""><wsa:Action>http://www.test.com/test/Services/Outage/IOutageService/GetLocations</wsa:Action></soap:Header><soap:Body><out:GetLocations/></soap:Body></soap:Envelope>");

在内容类型中定义操作

Content-Type: application/soap+xml;charset=UTF-8;action="http://www.test.com/test/Services/Outage/IOutageService/GetLocations"

然后我在WebRequest中更改了

内容类型

var contentString =  @"application/soap+xml;charset=UTF-8;action=""http://www.test/test/Services/Outage/IOutageService/GetLocations""";
        webRequest.ContentType = contentString;

代码从 Web 服务接收 xml。只需要注意双引号!!!
