Question

SCENARIO

我必须使用.NET客户端访问Web服务。该服务是Apache CXF Web服务。需要用户名和密码验证。我创建了代理。我已经设置了凭证。

MyServiceReference proxy = new MyServiceReference();
proxy.Credentials = new NetworkCredential("username", "password");
string res = proxy.Method1();

当我运行客户端时，抛出以下异常：

System.Web.Services.Protocols.SoapHeaderException: An error was discovered processing the <wsse:Security> header

服务发布者告诉我，SOAP头中不存在凭据。所以，我想IWebProxy.Credentials不是设置身份验证的正确方法。

问题

那么，如何设置身份验证所需的SOAP标头？

最终我不得不调用创建整个SOAP消息的服务并创建HttpWebRequest。在SOAP消息中，我手动指定安全标头：

<soapenv:Header>
  <wsse:Security soapenv:mustUnderstand='1' xmlns:wsse='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd'>
     <wsse:UsernameToken wsu:Id='UsernameToken-1' xmlns:wsu='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd'>
        <wsse:Username>Foo</wsse:Username>
        <wsse:Password Type='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'>Bar</wsse:Password>
        <wsse:Nonce EncodingType='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary'>qM6iT8jkQalTDfg/TwBUmA==</wsse:Nonce>
        <wsu:Created>2012-06-28T15:49:09.497Z</wsu:Created>
     </wsse:UsernameToken>
  </wsse:Security>
</soapenv:Header>

这里是服务客户端：

String Uri = "http://web.service.end.point"
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Uri);
req.Headers.Add("SOAPAction", "\"http://tempuri.org/Register\"");
req.ContentType = "text/xml;charset=\"utf-8\"";
req.Accept = "text/xml";
req.Method = "POST";

String SoapMessage = "MySoapMessage, including envelope, header and body"
using (Stream stm = req.GetRequestStream())
{
    using (StreamWriter stmw = new StreamWriter(stm))
    {
        stmw.Write(SoapMessage);
    }
}


try
{
    WebResponse response = req.GetResponse();
    StreamReader sr = new StreamReader(response.GetResponseStream());
    log.InfoFormat("SoapResponse: {0}", sr.ReadToEnd());
}
catch(Exception ex)
{
    log.Error(Ex.ToString());
}
