Tomcat:绕过指定IP地址的基本身份验证
我已经配置了tomcat进行基本身份验证。我不希望任何人都能访问我的Web应用程序,但该应用程序正在提供Web服务。所以我想从基本身份验证中绕过特定的IP地址。(该IP不需要身份验证。)
tomcat-users.xml:
<tomcat-users><user username="user" password="password" roles="user"/>
</tomcat-users>
web.xml:
<security-constraint><web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>You must enter your login credentials to continue</realm-name>
</login-config>
<security-role>
<description>
The role that is required to log in to the Application
</description>
<role-name>user</role-name>
</security-role>
谢谢,谢坦。
回答:
如果您只想允许几个IP地址,而不允许其他人使用,则您需要Remote Address Filter
Valve。
如果希望来自未知IP地址的客户端看到基本的登录对话框,并且可以自定义登录,则可以登录Valve
。在源RemoteAddrValve
(和它的父类RequestFilterValve
是出发点良好的。看看我以前的答案太。
无论如何,下面是概念证明代码。如果客户端来自受信任的IP
Principal
,Request
则会填入,因此登录模块将不会要求输入密码。否则它不会碰到Request
对象,并且用户可以照常登录。
import java.io.IOException;import java.security.Principal;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import org.apache.catalina.connector.Request;
import org.apache.catalina.connector.Response;
import org.apache.catalina.realm.GenericPrincipal;
import org.apache.catalina.valves.ValveBase;
public class AutoLoginValve extends ValveBase {
private String trustedIpAddress;
public AutoLoginValve() {
}
@Override
public void invoke(final Request request, final Response response)
throws IOException, ServletException {
final String remoteAddr = request.getRemoteAddr();
final boolean isTrustedIp = remoteAddr.equals(trustedIpAddress);
System.out.println("remoteAddr: " + remoteAddr + ", trusted ip: "
+ trustedIpAddress + ", isTrustedIp: " + isTrustedIp);
if (isTrustedIp) {
final String username = "myTrusedUser";
final String credentials = "credentials";
final List<String> roles = new ArrayList<String>();
roles.add("user");
roles.add("admin");
final Principal principal = new GenericPrincipal(username,
credentials, roles);
request.setUserPrincipal(principal);
}
getNext().invoke(request, response);
}
public void setTrustedIpAddress(final String trustedIpAddress) {
System.out.println("setTrusedIpAddress " + trustedIpAddress);
this.trustedIpAddress = trustedIpAddress;
}
}
还有一个配置示例server.xml
:
<Valve className="autologinvalve.AutoLoginValve" trustedIpAddress="127.0.0.1" />
