如何使"HTTPS redirect"在 WebSphere Application Server Liberty Profile 上工作？

Question

我想让HTTP重定向在WebSphere Application Server Liberty Profile（WLP）上工作。例如：-

当用户键入：http://localhost:8080/helloworld，浏览器应自动转到（被重定向）https://localhost:9443/helloworld

为此，我遵循了本文件第6.2节第136页的规定。

下面是示例server.xml和web.xml:-

server.xml

<server description="new server">
<!-- Enable features -->
<featureManager>
    <feature>jsp-2.2</feature>
    <feature>wab-1.0</feature>
    <feature>jaxrs-1.1</feature>
    <feature>blueprint-1.0</feature>
    <feature>localConnector-1.0</feature>
    <feature>ssl-1.0</feature>
    <feature>appSecurity-2.0</feature>
</featureManager>
<httpEndpoint host="localhost" httpPort="8081" httpsPort="9442" id="defaultHttpEndpoint">
</httpEndpoint>
<applicationMonitor updateTrigger="mbean"/>
<keyStore id="defaultKeyStore" password="{xor}Lz4sLCgwLTtu"/>
<application id="Hello.app" location="Hello.app.eba" name="Hello.app" type="eba"/>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <display-name>Hello</display-name>
    <security-constraint>
        <display-name>HTTPS Redirect Security Constraint</display-name>
        <web-resource-collection>
            <web-resource-name>Sample Web Service service</web-resource-name>
            <url-pattern>/Hello</url-pattern>
            <http-method>GET</http-method>
        </web-resource-collection>
        <user-data-constraint>
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>
        </user-data-constraint>
    </security-constraint>
</web-app>

为简洁起见，已删除<servlet>和<servlet-mapping>标签。

以下是我正在使用的版本：-Java 7、WLP 8.5.5、Eclipse Juno、Google Chrome。

如有任何帮助，关于HTTPS重定向不起作用的指导方针将不胜感激。

Answer 1

我怀疑问题出在您的安全约束中。看看它，我建议将您的url模式更改为：

/helloworld

而不是：

/你好

如果要匹配多个资源，可以使用通配符，例如：

1. /*-匹配所有内容
2. /helloworld/*-匹配url路径中包含helloworld/的所有内容
3. *.jsp-使用jsp扩展名匹配所有文件

要使HTTPS重定向在WLP上工作，应注意以下几点：-

1. 在WLP的server.xml中添加用户、角色和密码
2. 将应用程序绑定到安全角色
3. 在WLP的server.xml中添加appSecurity-2.0功能
4. 在web.xml中添加以下标记
   1. <login-config>
   2. <security-constraint>
   3. <security-constraint><web-resource-name></security-constraint>
   4. <security-constraint><auth-constraint></security-constraint>
   5. <security-constraint><user-data-constraint></security-constraint>

以下是详细的步骤：-

1.在WLP的server.xml中添加用户、角色和密码

<basicRegistry id="MyRegistry">
    <user password="{xor}Mjo6MT4z" name="anuroop" />
    <group name="MyGroup">
        <member name="anuroop" />
    </group>
</basicRegistry>

2.将应用程序绑定到安全角色

<application id="Hello.app" location="Hello.app.eba" name="Hello.app" type="eba">
    <application-bnd>
        <security-role name="Manager">
        <group name="MyGroup" />
    </security-role>
    </application-bnd>
</application>

3.在WLP的server.xml中添加appSecurity-2.0功能

<featureManager>
    <feature>appSecurity-2.0</feature>
</featureManager>

4.1、4.2、4.3、4.4、4.5

<login-config>
    <auth-method>FORM</auth-method>
    <realm-name>BasicRegistry</realm-name>
    <form-login-config>
        <form-login-page>/Login.jsp</form-login-page>
        <form-error-page>/LoginError.jsp</form-error-page>
    </form-login-config>
</login-config>
<security-constraint>
        <display-name>HTTPS Redirect Security Constraint</display-name>
        <web-resource-collection>
            <web-resource-name>Sample Web Service service</web-resource-name>
            <url-pattern>/Hello</url-pattern>
            <http-method>GET</http-method>
        </web-resource-collection>
    <auth-constraint>
        <role-name>Manager</role-name>
    </auth-constraint>
    <user-data-constraint>
    <description>Ensure to allow only confidential communication</description>
    <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>
</security-constraint>

我用不同的方法解决了这个问题，但我认为接受的答案可能更好。您可以编写servlet过滤器，然后修改web.xml以将其与路径相关联。

web.xml代码：

  <web-app id="WebApp">
      <filter>
        <filter-name>HTTPSFilter</filter-name>
        <filter-class>
        HTTPSFilter
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>HTTPSFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    ...
 </web-app>

过滤器代码：

public class HTTPSFilter implements Filter {
    public void doFilter(ServletRequest req, 
                         ServletResponse res,
                         FilterChain chain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;
        // Forward to HTTPS if insecure HTTP was used
        if(!req.getScheme().startsWith("https")) {
            // Modify the Response object to be the SSL version of the URL
            String host         = request.getLocalName();
            String URI         = request.getRequestURI();
            if(URI == null) { URI = ""; }
            String queryString  = request.getQueryString();
            if(queryString == null) { queryString = ""; }
            response.sendRedirect("https://" + host + ":9443" + URI + ("".equalsIgnoreCase(queryString) ? "":"?") + queryString);
        }
        chain.doFilter(req, res);
    }
    public void init(FilterConfig config) throws ServletException {
    }
    public void destroy() {
    }
}
