无法在ASP.NET Core中对SOAP服务进行身份验证

我试图从ASP.NET核心库项目中使用SOAP Web服务。

我已经安装了为我创建代理类的Mictosoft WCF Web服务引用提供程序,但是我的身份验证有问题。

我的代码目前看起来像这样:

var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportWithMessageCredential);

var address = new EndpointAddress(@"https://myserviceaddress.asmx");
var client = new TestApiClient(binding, address);
client.ClientCredentials.UserName.UserName = "testusername";
client.ClientCredentials.UserName.Password = "testpassword";
var result = await client.GetDataAsync(params);

我尝试了一些不同的方法,但我要么是未经授权,要么是变体:The value 'TransportWithMessageCredential' is not supported in this context for the binding security property 'securityMode'.

我想我也应该在binding.Security.Message上设置一些属性,但binding.Security上唯一存在的属性是TransportMode

有人知道如何正确设置吗?

还有其他更好的方法可以从ASP.NET Core中使用SOAP服务吗?我想要一种不必创建代理类的动态方式,但如果必须,我可以使用代理,但我需要能够使用用户和密码进行身份验证,我必须使用HTTPS。

.NET Core 2.0上的WCF尚不支持消息安全性(TransportWithMessageCredential上的BasicHttpBinding)。

在同一个问题上苦苦挣扎了很多天后,由于.Net核心在此问题解答之前的支持非常有限,因此我设法通过自己构建整个信封并使用SimpleSoapClient来解决该问题。

我将尝试通过一个简单的示例逐步完成所有必需的步骤。因为每个步骤都有其自己的问题需要解决。

让我们假设您的模型是猫。

 public class Cat
    {
        public int Lives { get; set; }
    }

您的整个信封模型将如下所示:

public class Envelope
{
    public EnvelopeHeader Header { get; set; }
    public EnvelopeBody Body { get; set; }
}
public class EnvelopeHeader
{
    [XmlElementAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
    public Security Security { get; set; }
}


[XmlTypeAttribute(AnonymousType = true, Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
[XmlRootAttribute(Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", IsNullable = false)]
public class Security
{
    public SecurityUsernameToken UsernameToken { get; set; }
}


[XmlTypeAttribute(AnonymousType = true, Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
public  class SecurityUsernameToken
{
    public string Username { get; set; }
    public SecurityUsernameTokenPassword Password { get; set; }
    [XmlAttributeAttribute(Form = System.Xml.Schema.XmlSchemaForm.Qualified, Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd")]
    public string Id { get; set; }
}


[XmlTypeAttribute(AnonymousType = true, Namespace = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd")]
public  class SecurityUsernameTokenPassword
{
    [XmlAttributeAttribute()]
    public string Type { get; set; }
    [XmlTextAttribute()]
    public string Value { get; set; }
}

public  class EnvelopeBody
{
    public Cat Cat{ get; set; }
}

P.S:不要忘记在您身体中需要的地方包含XML名称空间。

下一步是将您的Envelop模型序列化为XML字符串。

string xml;
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
using (MemoryStream ms = new MemoryStream())
  {
    using (XmlWriter writer = XmlWriter.Create(ms, settings))
     {
       XmlSerializerNamespaces names = new XmlSerializerNamespaces();
       names.Add("", "");//add your needed namespaces here
       XmlSerializer cs = new XmlSerializer(typeof(Envelope));
       var myEnv = new Envelope()
        {
         Header = new EnvelopeHeader()
          {
           Security = new Security()
            {
              UsernameToken = new SecurityUsernameToken()
               {
                Username = "",
                Password = new SecurityUsernameTokenPassword()
                {
                 Type = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText",//update type to match your case
                 Value = ""
                }
               }
              }
             },
             Body = new EnvelopeBody()
             {
              Cat = new Cat() { Lives = 7 }
             }
            };
            cs.Serialize(writer, myEnv, names);
            ms.Flush();
            ms.Seek(0, SeekOrigin.Begin);
            StreamReader sr = new StreamReader(ms);
            xml = sr.ReadToEnd();
          }
     }

最后使用以下命令发送XML信封:

  SoapEnvelope responseEnvelope = null;
        using (var client = SoapClient.Prepare().WithHandler(new DelegatingSoapHandler()
        {
            OnHttpRequestAsyncAction = async (z, x, y) =>
            {
                x.Request.Content = new StringContent(xml , Encoding.UTF8, "text/xml");
            }
        }))
        {
                responseEnvelope = client.SendAsync("url", "action",SoapEnvelope.Prepare()).Result;
        }

请注意,您需要根据情况更新许多选项。 我的案例是带有WCF的WSSE安全标头中的密码类型为“ PasswordText”。

您是否尝试在IIS上启用SSL?启用S​​SL将使您的服务在HTTP和& HTTPS。您的客户需要购买SSL证书。为此
