Spring Boot OAuth 始终重定向到 HTTP (IBM Cloud CF + Spring Boot 2)

Question

在 IBM Cloud CF Java Buildpack 上使用 Spring Boot OAuth 2...

https://github.com/ericis/oauth-cf-https-issue

*我已经尝试了以下所有组合。

使用此配置，应用程序陷入无限的重定向循环，其中 OAuth 重定向策略将其发送到 http，然后此配置将其发送到 https。

http.requiresChannel().anyRequest().requiresSecure()

如果没有此配置，用户可以通过 http 登录（不需要）。

完整配置：

http.
  requiresChannel().anyRequest().requiresSecure().
  authorizeRequests().
    // allow access to...
    antMatchers("favicon.ico", "/login", "/loginFailure", "/oauth2/authorization/ghe")
    .permitAll().anyRequest().authenticated().and().oauth2Login().
    // Codify "spring.security.oauth2.client.registration/.provider"
    clientRegistrationRepository(this.clientRegistrationRepository()).
    // setup OAuth2 client service to use clientRegistrationRepository
    authorizedClientService(this.authorizedClientService()).
    successHandler(this.successHandler()).
    // customize login pages
    loginPage("/login").failureUrl("/loginFailure").
    userInfoEndpoint().
      // customize the principal
      userService(this.userService());

我也试过了：

1. 使用https的服务器配置

   server:
     useForwardHeaders: true
     tomcat:
       protocolHeader: x-forwarded-proto
   

2. Servlet 过滤器

   import java.io.IOException;
   
   import javax.servlet.Filter;
   import javax.servlet.FilterChain;
   import javax.servlet.FilterConfig;
   import javax.servlet.ServletException;
   import javax.servlet.ServletRequest;
   import javax.servlet.ServletResponse;
   import javax.servlet.http.HttpServletRequest;
   import javax.servlet.http.HttpServletResponse;
   
   import org.slf4j.Logger;
   import org.slf4j.LoggerFactory;
   import org.springframework.beans.factory.annotation.Value;
   import org.springframework.stereotype.Component;
   
   @Component
   public class HttpToHttpsFilter implements Filter {
   
     private static final Logger log = LoggerFactory.getLogger(HttpToHttpsFilter.class);
   
     private static final String HTTP = "http";
     private static final String SCHEME_HTTP = "http://";
     private static final String SCHEME_HTTPS = "https://";
     private static final String LOCAL_ID = "0:0:0:0:0:0:0:1";
     private static final String LOCALHOST = "localhost";
   
     @Value("${local.ip}")
     private String localIp;
   
     public HttpToHttpsFilter() {
       // Sonar
     }
   
     @Override
     public void doFilter(final ServletRequest req, final ServletResponse res, final FilterChain chain)
         throws IOException, ServletException {
   
       final HttpServletRequest request = (HttpServletRequest) req;
   
       final HttpServletResponse response = (HttpServletResponse) res;
   
       // http, not localhost, not localhost ipv6, not local IP
       if (HTTP.equals(request.getScheme()) && 
           !LOCALHOST.equals(request.getRemoteHost()) && 
           !LOCAL_ID.equals(request.getRemoteHost()) && 
           (this.localIp != null && !this.localIp.equals(request.getRemoteHost()))) {
   
         final String query = request.getQueryString();
   
         String oldLocation = request.getRequestURL().toString();
   
         if (query != null) {
           oldLocation += "?" + query;
         }
   
         final String newLocation = oldLocation.replaceFirst(SCHEME_HTTP, SCHEME_HTTPS);
   
         try {
   
           log.info("HTTP redirect from {} to {} ", oldLocation, newLocation);
   
           response.sendRedirect(newLocation);
   
         } catch (IOException e) {
           log.error("Cannot redirect to {} {} ", newLocation, e);
         }
       } else {
         chain.doFilter(req, res);
       }
     }
   
     @Override
     public void destroy() {
       // Sonar
     }
   
     @Override
     public void init(FilterConfig arg0) throws ServletException {
       // Sonar
     }
   }

Answer 1

由于使用了 Spring 5，决定采用下一个解决方案（安全配置）：

        http
            .addFilterBefore(new ForwardedHeaderFilter(), OAuth2AuthorizationRequestRedirectFilter.class)

x-forwarded-* 标头参数现在处理正确。

Answer 2

即使不涉及 OAuth 行为，应用程序在当前设置的环境中也可能总是陷入无限循环。

虽然您可以告诉服务器使用转发标头，

server:
  useForwardHeaders: true

Tomcat 不会信任来自所有来源的 x-forwarded-* 标头。默认情况下，某些 IP 地址被视为内部地址 (RemoteIpValve#internalProxies)。

但是，在您使用的环境中，报告的代理 IP 地址可能不在此范围内。您可以使用以下配置允许所有 IP 地址：

server:
  tomcat:
    internal-proxies: .*

这允许所有代理，但如果无法直接访问应用程序，可能会满足您的需求。

Answer 3

已解决。有关与此相关的问题的详细信息，请访问： https://github.com/spring-projects/spring-security/issues/5535#issuecomment-407413944

正在运行的示例项目：https://github.com/ericis/oauth-cf-https-issue

简短回答：

需要明确配置应用程序以了解代理标头。我尝试过配置，但最终不得不使用最近添加到 Spring 中的 ForwardedHeaderFilter 类的实例。

@Bean
FilterRegistrationBean<ForwardedHeaderFilter> forwardedHeaderFilter() {

    final FilterRegistrationBean<ForwardedHeaderFilter> filterRegistrationBean = new FilterRegistrationBean<ForwardedHeaderFilter>();

    filterRegistrationBean.setFilter(new ForwardedHeaderFilter());
    filterRegistrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);

    return filterRegistrationBean;
}
