生成 SOAP 标头 WCF

Question

我想生成一个soap 标头，以便访问客户端Web 服务。该服务受 WS-Security 保护，我需要添加以下标头：

<soapenv:Header>
    <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
    <wsse:UsernameToken wsu:Id="UsernameToken-A1246F3623454D79AA14805153047445">
        <wsse:Username>Usuario</wsse:Username>
        <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">oU1uQxxyrF5wxxx5B+P/Y9uFW/M3DNEc=</wsse:Password>
        <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">52sq2ilGc+9xxxxxxLBRDQ==</wsse:Nonce>
        <wsu:Created>2016-11-30T14:15:04.744Z</wsu:Created>
    </wsse:UsernameToken>
    </wsse:Security>
</soapenv:Header>

我之前通过 WCF 配置生成了其他类型的标头，但我正在努力解决这个问题。

下面的 WCF 代码会生成类似的 SOAP Header，接收者可以读取消息。

const string apiUrl = "https://somewebservices.com", 
    apiUserName = "username", 
    apiPassword = "password";

var endpointAddress = new EndpointAddress(new Uri(apiUrl));

var securityElement = SecurityBindingElement.CreateUserNameOverTransportBindingElement();
securityElement.AllowInsecureTransport = false;
securityElement.EnableUnsecuredResponse = true;
securityElement.IncludeTimestamp = false;
var encodingElement = new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8);
var transportElement = new HttpsTransportBindingElement();
var binding = new CustomBinding(securityElement, encodingElement, transportElement);

// Then assign username and password based on the proxy. For example -
var service = new SomeProxy(binding, endpointAddress);
service.ClientCredentials.UserName.UserName = apiUserName;
service.ClientCredentials.UserName.Password = apiPassword;

结果

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
