如何验证基于soap的java Web服务？

Question

我正在使用Java开发基于Soap的Web服务.任何人都可以让我知道如何验证使用Web服务的客户端？

谢谢.

可能最好但最复杂的是具有各种身份验证方法的WS-Security.但它最复杂,对企业环境有益.它允许您创建端到端身份验证,并有很多选项.您可以在简单的情况下使用Web Services Security UsernameToken Profile

    <S12:Envelope xmlns:S11="..." xmlns:wsse="..." xmlns:wsu= "...">
  <S12:Header>
  ...
    <wsse:Security>
      <wsse:UsernameToken>
        <wsse:Username>NNK</wsse:Username>
        <wsse:Password Type="...#PasswordDigest">weYI3nXd8LjMNVksCKFV8t3rgHh3Rw==</wsse:Password>
        <wsse:Nonce>WScqanjCEAC4mQoBE07sAQ==</wsse:Nonce>
        <wsu:Created>2003-07-16T01:24:32</wsu:Created>
      </wsse:UsernameToken>
    </wsse:Security>
  ...
  </S12:Header>
...
</S12:Envelope>

我不知道你使用的库,但这里有一篇很好的文章如何将Rampart安装到Axis2并实现UsernameToken处理.

但在某些简化案例中,您只需对Web服务器(通过SSL)进行HTTP基本身份验证即可.这可能是最糟糕的解决方案,但有时可能最容易实施.另一个与soap无关的解决方案可以是相互认证的SSL(使用客户端身份验证).

我们可以实现不同的方式和不同类型的安全性:消息级安全性

• 传输级安全性:例如HTTP Basic/Digest和SSL
• 消息级安全性:如WS-Security的,XML数字签名,XML加密,XKMS(X ML ķ EY 中号 anagement 小号 pecification),XACML(E X tensible 甲 CCESS Ç ONTROL 中号 arkup 大号 anguage),SAML(小号 ecure 甲 ssertion M arkup L anguage),ebXML消息服务,自由联盟项目.更多的
• 访问控制安全性:安全角色是根据特定条件授予用户或组的权限.

最常见的是我们将WS-Security用于SOAP Web服务.一个WS-安全配置文件决定了WS-Security是如何启用.

1. WSS X.509令牌配置文件:将X.509框架用于WSS X.509安全配置文件.
2. WSS UsernameToken配置文件:指定X.509令牌配置文件时,您还可以在SOAP请求中提供UsernameToken.

例:

<wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">
  <wsse:Username>user</wsse:Username>
  <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">CBb7a2itQDgxVkqYnFtggUxtuqk=</wsse:Password>
  <wsse:Nonce>5ABcqPZWb6ImI2E6tob8MQ==</wsse:Nonce>
  <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
</wsse:UsernameToken>

上面的元素包含在SOAP头中,如下所示:

SOAPEnvelope envelope = smc.getMessage().getSOAPPart().getEnvelope();
    SOAPHeader header = envelope.addHeader();
    SOAPElement security = header.addChildElement("Security", "wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
    SOAPElement usernameToken = security.addChildElement("UsernameToken", "wsse");
    SOAPElement username = usernameToken.addChildElement("Username", "wsse");
    username.addTextNode(user);

    SOAPElement password = usernameToken.addChildElement("Password", "wsse");
    password.setAttribute("Type", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest");
    password.addTextNode(encodedPass); //encodedPass = Base64 ( SHA-1 ( nonce + created + password ) )

    SOAPElement nonce =
        usernameToken.addChildElement("Nonce", "wsse");
    nonce.addTextNode(Base64.encodeBytes(nonceString.getBytes()));

    SOAPElement created = usernameToken.addChildElement("Created", "wsu","http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");

    created.addTextNode(creatTime);

以下示例很简单,仅将用户和密码添加到HTTP标头.

• 使用JAX-WS进行应用程序身份验证 以下是一个详细示例,向您展示如何使用JAX-WS处理应用程序级别身份验证.
• 使用JAX-WS +进行容器身份验证(Tomcat版本) 这是一个详细示例,向您展示如何在Tomcat下使用JAX-WS实现容器身份验证.

使用WebServiceContext接口使用JAX-WS进行应用程序身份验证

WebServiceImpl.java

package com.javacodegeeks.enterprise.ws;

import java.util.List;
import java.util.Map;

import javax.annotation.Resource;
import javax.jws.WebService;
import javax.xml.ws.WebServiceContext;
import javax.xml.ws.handler.MessageContext;

@WebService(endpointInterface = "com.javacodegeeks.enterprise.ws.WebServiceInterface")
public class WebServiceImpl implements WebServiceInterface {

    @Resource
    WebServiceContext webServiceContext;

    @Override
    public String getHelloWorldAsString(String str) {

        MessageContext messageContext = webServiceContext.getMessageContext();

        // get request headers
        Map<?,?> requestHeaders = (Map<?,?>) messageContext.get(MessageContext.HTTP_REQUEST_HEADERS);
        List<?> usernameList = (List<?>) requestHeaders.get("username");
        List<?> passwordList = (List<?>) requestHeaders.get("password");

        String username = "";
        String password = "";

        if (usernameList != null) {
            username = usernameList.get(0).toString();
        }

        if (passwordList != null) {
            password = passwordList.get(0).toString();
        }

                // of course this is not real validation
                // you should validate your users from stored databases credentials
        if (username.equals("nikos") && password.equals("superpassword")) {

            return "Valid User :"+str;

        } else {

            return "Unknown User!";
        }
    }
}

WebServiceClient.java

package com.javacodegeeks.enterprise.ws.client;

import java.net.URL;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.xml.namespace.QName;
import javax.xml.ws.BindingProvider;
import javax.xml.ws.Service;
import javax.xml.ws.handler.MessageContext;
import com.javacodegeeks.enterprise.ws.WebServiceInterface;

public class WebServiceClient{

    public static void main(String[] args) throws Exception {

        URL wsdlUrl = new URL("http://localhost:8888/webservice/helloworld?wsdl");    
        //qualifier name ...
        QName qname = new QName("http://ws.enterprise.javacodegeeks.com/", "WebServiceImplService");
         Service service = Service.create(wsdlUrl, qname);

        WebServiceInterface sayHello = service.getPort(WebServiceInterface.class);
        Map<String, Object> requestContext = ((BindingProvider)sayHello).getRequestContext();

        requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "http://localhost:8888/webservice/helloworld?wsdl");

        Map<String, List<String>> requestHeaders = new HashMap<String, List<String>>();
        requestHeaders.put("username", Collections.singletonList("nikos"));
        requestHeaders.put("Password", Collections.singletonList("superpassword"));
        requestContext.put(MessageContext.HTTP_REQUEST_HEADERS, requestHeaders);

        System.out.println(sayHello.getHelloWorldAsString("- This is Java Code Geeks"));

    }
}
