Zuul 代理和 Spring OAuth 重定向问题

Question

我正在尝试从第三方 SSO 服务器获取 JWT 令牌。在第一次授权请求中需要一个额外的参数，例如

https://[third-party-sso-server]/oauth2/authorize?client_id=[my-client-id]&redirect_uri=http://localhost:8080/login&response_type=code&additional_param=[value]

但是 Spring Security 有标准的重定向 URI： https://[third-party-sso-server]/oauth2/authorize?client_id=[my-client-id]&redirect_uri=http://localhost:8080/login&response_type=code&state=[state-value]
所以我不能使用任何过滤器或 HeaderWriter 添加这个附加参数。而且我无法使用 DefaultRedirectStrategy 类更改重定向策略。 我的代码基于本教程https://spring.io/guides/tutorials/spring-boot-oauth2/#_social_login_manual

我刚刚通过添加额外的过滤器解决了这个问题并更改了默认重定向策略

`

       ...
        @Override
            public void configure(HttpSecurity http) throws Exception {
                http.antMatcher("/**").addFilterBefore(ssoFilter(),       BasicAuthenticationFilter.class).addFilterAfter(oAuth2ClientContextFilterFilter(), SecurityContextPersistenceFilter.class)
                        .authorizeRequests().antMatchers("/").authenticated();
            }

            public Filter oAuth2ClientContextFilterFilter() 
            {
                OAuth2ClientContextFilter  filter = new OAuth2ClientContextFilter();
                filter.setRedirectStrategy(new CustomRedirectStrategy());
                return filter;
            }
        ...

    public class CustomRedirectStrategy extends DefaultRedirectStrategy {

    @Override
    public void sendRedirect(HttpServletRequest request, HttpServletResponse response, String url) throws IOException {
        super.sendRedirect(request, response, url+"&additional_param=value");
    }

}
