在Google App Engine上启用Oauth2sso

我试图在我的应用程序中使用Google应用程序引擎获取spring security oauth2设置.一切似乎在本地工作正常,但当我部署到应用程序引擎时,事情开始崩溃.我通过谷歌进行身份验证后,将其转发给Whitelabel错误页面.在控制台中我看到这个错误:

http://my-application.appspot.com/login?state=t…m&session_state=8b67f5df659a8324430803973b9e1726e39fd454..1ae3&prompt=none 
401 (Unauthorized)

我用这个application.yml文件设置我的auth:

security:
  oauth2:
client:
  clientId: client-key
  clientSecret: secret-key
  accessTokenUri: https://www.googleapis.com/oauth2/v4/token
  userAuthorizationUri: https://accounts.google.com/o/oauth2/v2/auth
  clientAuthenticationScheme: form
  scope:
    - openid
    - email
    - profile
    - https://www.googleapis.com/auth/cloud-platform
resource:
  userInfoUri: https://www.googleapis.com/oauth2/v3/userinfo
  preferTokenInfo: true

我的安全配置看起来像这样:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
        .and()
            .authorizeRequests()
            .antMatchers("/static/**").permitAll()
            .antMatchers("/**").hasAuthority("ROLE_ADMIN")
            .anyRequest().authenticated()
        .and()
            .exceptionHandling()
            .accessDeniedPage("/403");
}

我在google凭据页面上配置了Oauth ID,以允许授权的javascript来源:

http://my-application.appspot.com
https://my-application.appspot.com
http://localhost:8080

并且授权的重定向URI为:

http://my-application.appspot.com/login
https://my-application.appspot.com/login
http://localhost:8080/login

我部署到GAE后,为什么我可能会收到未经授权的错误？

谢谢,
