如何在 WSO2 ESB 4.9.0 中启用代理服务安全性

Question

我全新安装了 WSO2 ESB 4.9.0，我正在尝试使用 HTTP 基本身份验证来保护代理服务，但我失败了。

我试过this tutorial from official documentation，但这种方法在 4.8.1 之前是可行的。在 4.9.0 版本中，我无法单击“安全”来打开服务页面的“安全”。

所以我尝试了另一种方法：

我在注册表中创建了策略 UTOverTransport（从 4.8.1 复制）。

<wsp:Policy wsu:Id="UTOverTransport" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
    <wsp:ExactlyOne>
        <wsp:All>
            <sp:TransportBinding xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
                <wsp:Policy>
                    <sp:TransportToken>
                        <wsp:Policy>
                            <sp:HttpsToken RequireClientCertificate="false"/>
                        </wsp:Policy>
                    </sp:TransportToken>
                    <sp:AlgorithmSuite xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
                        <wsp:Policy>
                            <sp:Basic256/>
                        </wsp:Policy>
                    </sp:AlgorithmSuite>
                    <sp:Layout>
                        <wsp:Policy>
                            <sp:Lax/>
                        </wsp:Policy>
                    </sp:Layout>
                    <sp:IncludeTimestamp/>
                </wsp:Policy>
            </sp:TransportBinding>
            <sp:SignedSupportingTokens xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
                <wsp:Policy>
                    <sp:UsernameToken xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy" sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/AlwaysToRecipient"/>
                </wsp:Policy>
            </sp:SignedSupportingTokens>
        </wsp:All>
    </wsp:ExactlyOne>
    <rampart:RampartConfig xmlns:rampart="http://ws.apache.org/rampart/policy">
        <rampart:encryptionUser>useReqSigCert</rampart:encryptionUser>
        <rampart:timestampPrecisionInMilliseconds>true</rampart:timestampPrecisionInMilliseconds>
        <rampart:timestampTTL>300</rampart:timestampTTL>
        <rampart:timestampMaxSkew>300</rampart:timestampMaxSkew>
        <rampart:timestampStrict>false</rampart:timestampStrict>
        <rampart:tokenStoreClass>org.wso2.carbon.security.util.SecurityTokenStore</rampart:tokenStoreClass>
        <rampart:nonceLifeTime>300</rampart:nonceLifeTime>
    </rampart:RampartConfig>
</wsp:Policy>

在代理服务配置中我添加了：

   <parameter name="allowRoles">admin</parameter>
   <parameter name="ScenarioID">scenario1</parameter>
   <enableSec/>
   <policy key="conf:/repository/policies/UTOverTransport"/>

现在在管理控制台中，我看到代理服务是安全的，但是当我调用此服务时出现错误：

java.lang.ClassCastException: org.apache.axiom.om.impl.dom.ElementImpl cannot be cast to org.apache.axiom.soap.SOAPHeaderBlock
    org.wso2.carbon.security.pox.POXSecurityHandler.isSOAPWithoutSecHeader(POXSecurityHandler.java:362)
    org.wso2.carbon.security.pox.POXSecurityHandler.invoke(POXSecurityHandler.java:102)
    org.apache.axis2.engine.Phase.invokeHandler(Phase.java:340)

请求：

         </wsse:UsernameToken>
      </wsse:Security>
   </soapenv:Header>
   <soapenv:Body/>
</soapenv:Envelope>

我还尝试使用带有 SecurityAdminService 的 API 和操作 applySecurity（这在 4.8.1 中有效）来保护代理，但我收到错误 org.apache.axis2.AxisFault: Service with name test not found。

有人可以帮我解释一下怎么做吗？

基本身份验证的策略文件（带有用户名令牌）应如下所示：

<wsp:Policy wsu:Id="UTOverTransport"
xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

        <sp:TransportBinding xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
            <wsp:Policy>
                <sp:TransportToken>
                    <wsp:Policy>
                        <sp:HttpsToken RequireClientCertificate="false"/>
                    </wsp:Policy>
                </sp:TransportToken>
                <sp:AlgorithmSuite>

                    <wsp:Policy>

                <sp:IncludeTimestamp/>
            </wsp:Policy>
        </sp:TransportBinding>

    </wsp:All>
</wsp:ExactlyOne>
<rampart:RampartConfig xmlns:rampart="http://ws.apache.org/rampart/policy">

</rampart:RampartConfig>
<sec:CarbonSecConfig xmlns:sec="http://www.wso2.org/products/carbon/security">
    <sec:Authorization>
        <sec:property name="org.wso2.carbon.security.allowedroles">admin</sec:property>
    </sec:Authorization>
</sec:CarbonSecConfig>

在代理服务配置中添加：

<policy key="conf:/repository/policies/UTOverTransport"/>
<enableSec/>

conf:/repository/policies/UTOverTransport 是策略文件的路径

不需要开发者工作室。

我希望这会有所帮助

从 ESB 4.9.0 版本开始，所有这些服务质量 (QOS) 功能均已从 WSO2 ESB 管理控制台中删除。因此，我们建议您使用与 ESB 4.9.0 版本兼容的 WSO2 Developer Studio 3.8 版本来完成与 QOS 相关的工作，例如安全性、可靠性等。
