WS安全性 - 用户名令牌配置文件

标签: web-services websphere ws-security

我有一个wsdl文件,我正在为WAS 8.0编写一个客户端

我在ApplicationResources.properties中保留了soap请求所需的用户名/密码。

我正在使用'wss-username-token-profile-1.0',

我无法找到如何实现这一点。

我需要知道,如何编写policy.xml以及如何在Webservice clienr中使用。

Soap请求必须包含用户名令牌wss配置文件的相应标头元素。如果您使用Java,您可以使用Soap处理程序或SAAJ手动创建元素。在Websphere中,您可以使用称为“策略集”的功能对此支持进行元编程,并配置各种策略集和绑定。

这是一篇很好的文章,描述了如何使用配置方法完成此操作: http://www.ibm.com/developerworks/websphere/library/techarticles/1103_balakrishnan/1103_balakrishnan.html

以下是使用SAAJ以编程方式添加此标头的示例:

public class WssHandler implements SOAPHandler<SOAPMessageContext> {

    private static final Logger cTRACE = Logger.getLogger(WssHandler.class.getName());

    // SOAP
    private static final String cWSSE = "wsse";
    private static final String cURL = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd";
    private static final String cNODE_SECURITY = "Security";
    private static final String cNODE_USRTOKEN = "UsernameToken";
    private static final String cNODE_USERNAME = "Username";
    private static final String cNODE_PASSWORD = "Password";

    private String iUsername;
    private String iPassword;

    /**
     * Constructor for SOAP handler with specific wss credentials.
     * @param aUsername wss username
     * @param aPassword wss password
     */
    public WssHandler(String username, String passwd) {
        super();
        iUsername = username;
        iPassword = passwd;
    }

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        if (cTRACE.isLoggable(Level.FINEST)) {
            cTRACE.logp(Level.FINEST,
                    WssHandler.class.getName(),
                    "handleMessage", "add WSS credentials for user "+iUsername);
        }

        try {
            SOAPMessage tMessage = context.getMessage();
            SOAPEnvelope tSoapEnvelope = tMessage.getSOAPPart().getEnvelope();

            // header
            SOAPHeader tHeader = tSoapEnvelope.getHeader();
            if (tHeader==null) {
                // no header yet, create one
                tHeader = tSoapEnvelope.addHeader();
            }

            // security node
            Name tWsseHeaderName = tSoapEnvelope.createName(cNODE_SECURITY, cWSSE, cURL);
            SOAPHeaderElement tSecurityElement = tHeader.addHeaderElement(tWsseHeaderName);
            tSecurityElement.setMustUnderstand(true);

            Name tUserTokenElementName = tSoapEnvelope.createName(cNODE_USRTOKEN, cWSSE, cURL);
            SOAPElement tUserTokenElement = tSecurityElement.addChildElement(tUserTokenElementName);
            tUserTokenElement.removeNamespaceDeclaration(cWSSE);
            tUserTokenElement.addNamespaceDeclaration("wsu", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");

            // user name child
            Name tUsernameElementName = tSoapEnvelope.createName(cNODE_USERNAME, cWSSE, cURL);
            SOAPElement tUsernameElement = tUserTokenElement.addChildElement(tUsernameElementName);
            tUsernameElement.removeNamespaceDeclaration(cWSSE);
            tUsernameElement.addTextNode(iUsername);

            // password child
            Name tPasswordElementName = tSoapEnvelope.createName(cNODE_PASSWORD, cWSSE, cURL);
            SOAPElement tPasswordElement = tUserTokenElement.addChildElement(tPasswordElementName);
            tPasswordElement.removeNamespaceDeclaration(cWSSE);
            tPasswordElement.addTextNode(iPassword);
            tPasswordElement.setAttribute("Type", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText");
        } catch (SOAPException e) {
            if (cTRACE.isLoggable(Level.SEVERE)) {
                cTRACE.logp(Level.SEVERE,
                        WssHandler.class.getName(),
                        "handleMessage", "Unable to add WSS credentials", e);
            }
            // stop processing
            return false;
        }

        // continue processing
        return true;
    }

    @Override
    public boolean handleFault(SOAPMessageContext context) {
        return true;
    }

    @Override
    public void close(MessageContext context) {
        // nothing to do
    }

    @Override
    public Set<QName> getHeaders() {
        return null;
    }
