正确的方式为SOAP Web服务传递WSSE Usernametoken

我正在尝试通过相应的wsdl使用Web服务。此服务依赖于符合Web Services Security Basic Security Profile 1.0的身份验证，包括请求中必须包含http://docs.oasis-open.org/wss/2004/01/oasis-200401wss-wssecurity-secext-1.0.xsd的正确xmls名称空间。

示例：

<wsse:UsernameToken xmlns:wsse='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd' >
   <wsse:Username>
      Bob
   </wsse:Username>
   <wsse:Password Type='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'>
      1234
   </wsse:Password>
</wsse:UsernameToken>

我的第一次尝试是针对wsdl的Add Service Reference以及使用它们生成的代理

ServicePointManager.ServerCertificateValidationCallback = 
    (object s, X509Certificate certificate, X509Chain chain,
                     SslPolicyErrors sslPolicyErrors) => true;

var basicHttpBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
basicHttpBinding.Security.Transport.ClientCredentialType = 
                                                HttpClientCredentialType.Basic;

var endpoint = new EndpointAddress("https://secure-ausomxana.crmondemand.com/..."

using (var client = new ContactClient(basicHttpBinding, endpoint))
{

    var credential = client.ClientCredentials.UserName;
    credential.UserName = "bob";
    credential.Password = "1234";

    var input = ...    
    var output = client.ContactQueryPage(input);
}

然而，尝试使用Fiddler查询SOAP消息时，我发现没有添加UsernameToken元素。

履行此合同的正确方法是什么？

编辑：跟随@John Saunders的回复我试图改变我的代码以使用wsHttpBinding 

var wsHttpBinding = new WSHttpBinding(SecurityMode.Transport);
wsHttpBinding.Security.Transport.ClientCredentialType =
                                         HttpClientCredentialType.Basic;

使用此绑定，SOAP消息变为

<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">document/urn:crmondemand/ws/ecbs/contact/10/2004:ContactQueryPage</a:Action>
    <a:MessageID>urn:uuid:17807f44-1fcasfdsfd</a:MessageID>
    <a:ReplyTo>
      <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
    </a:ReplyTo>
    <a:To s:mustUnderstand="1">https://secure-ausomxana.crmondemand.com/Services/Integration</a:To>
  </s:Header>
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <ContactQueryPage_Input xmlns="urn:crmondemand/ws/ecbs/contact/10/2004">
      <ListOfContact xmlns="urn:/crmondemand/xml/Contact/Query">
        <Contact>
          <Id>1-asdfd</Id>
        </Contact>
      </ListOfContact>
    </ContactQueryPage_Input>
  </s:Body>
</s:Envelope>

这会添加Header元素，而不是wsse:UsernameToken元素用于引用，使用BasicHttpBinding的原始soap消息是

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <ContactQueryPage_Input xmlns="urn:crmondemand/ws/ecbs/contact/10/2004">
      <ListOfContact xmlns="urn:/crmondemand/xml/Contact/Query">
        <Contact>
          <Id>1-asdfds</Id>
        </Contact>
      </ListOfContact>
    </ContactQueryPage_Input>
  </s:Body>
</s:Envelope>

如果我将绑定更改为

var wsHttpBinding = new WSHttpBinding(SecurityMode.TransportWithMessageCredential);
wsHttpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
wsHttpBinding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;

我得到的SOAP消息是

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

      </o:UsernameToken>
    </o:Security>
  </s:Header>
  <s:Body>
    <t:RequestSecurityToken xmlns:t="http://schemas.xmlsoap.org/ws/2005/02/trust">

      <t:KeySize>256</t:KeySize>
    </t:RequestSecurityToken>
  </s:Body>
</s:Envelope>

这似乎非常接近但是这似乎实际上加密了肥皂消息的主体，这是我不想发生的事情。

如果我仅使用wsHttpBinding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;指定SecurityMode.Transport，那么它会回到它所说的匿名位置。

我无法明确最后的障碍是什么？

最终解决方案想想我发布此内容它有助于某人，这里没有太大的不同，其他的UserToken对象被包装在一个安全节点中，这是我的服务提供商所需要的，似乎从我之前的例子中得到的输出是如何产生的。

如果您需要通过HTTPS发送UserName，您可以使用标准方法（如果您的WSDL已正确定义，则应通过添加服务引用自动为您创建）：

<bindings>
  <basicHttpBinding>
    <binding name="secured">
      <security mode="TransportWithMessageCredential">
        <message clientCredentialType="UserName" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint name="..." address="https://..." contract="..." binding="basicHttpBinding"
            bindingConfiguration="secured" />
</client>

您可以在代码中定义绑定：

var basicHttpBinding = new BasicHttpBinding(BasicHttpSecurityMode.TransportWithMessageCredential);
basicHttpBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;

您现在可以在代理中设置凭据：

client.ClientCredentials.UserName.UserName = "bob";
client.ClientCredentials.UserName.Password = "1234";

如果您只需要通过HTTP的UserNameToken配置文件而没有任何其他WS-Security基础结构，则最简单的方法是使用ClearUserNameBinding。

如果您需要来自客户端的所有请求的相同用户名和密码，您可以使用简单的basicHttpBinding而不需要任何安全性，并且包括配置中的静态头：

<client>
  <endpoint ...>
    <headers>
      <wsse:UsernameToken xmlns:wsse='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd' >
        <wsse:Username>Bob</wsse:Username>
        <wsse:Password Type='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'>
           1234
        </wsse:Password>
      </wsse:UsernameToken>
    </headers>
  </endpoint>
</client>

如果您需要更复杂的东西，请显示WSDL（安全断言）或样本SOAP请求的相关部分。如果您需要使用HTTP或HTTPS，请同时提及。

@Ladislav的回答是正确的。但是，我正在尝试使用{1.1}来获取我正在尝试使用的SOAP 1.1 Web服务。在Scott Hanselman的this blog post之后，我能够让它发挥作用。这是我最终使用的代码：

MessageSecurityException

答案 2 :(得分：3)

使用wsHttpBinding，而不是basicHttpBinding。

实际上，您应该只使用“添加服务引用”并指向服务的WSDL。
