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。

使用这个配置，应用程序陷入无限的重定向循环，OAuth重定向策略将它发送到http，然后这个配置将它发送到https.

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

没有这个配置，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：

要使用的服务器配置https

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

简答：

应用程序需要明确配置才能识别代理 headers。我尝试过配置，但最终不得不使用最近添加到 Spring.

的 ForwardedHeaderFilter class 实例

@Bean
FilterRegistrationBean<ForwardedHeaderFilter> forwardedHeaderFilter() {

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

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

    return filterRegistrationBean;
}

Answer 2

即使不涉及 OAuth 行为，应用程序也可能始终在当前设置的环境中陷入无限循环。

虽然您可以告诉服务器使用转发 headers,

server:
  useForwardHeaders: true

Tomcat 不会信任来自所有来源的 x-forwarded-* headers。默认情况下，某些 IP 地址被视为内部 IP 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该应用程序，则可以满足您的需要。

Answer 3

因为使用 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-* header 参数现在处理正确。
