Spring OAuth2隐式流程-Auth服务器未处理POST / oauth / authorize请求

Question

I have an authorization server ( http://localhost:8082 ), resource server and implicit client ( http://localhost:8080 ) project. The problem is that when the client asks for the authorization (token), the auth server shows the login screen but after the successful login it redirects to GET http://localhost:8082/ instead of to http://localhost:8082/authorize?client_id= ... (as requested by the client)

I am seeing this log:

Implicit client:

.s.o.c.t.g.i.ImplicitAccessTokenProvider : Retrieving token from http://localhost:8082/oauth/authorize
o.s.web.client.RestTemplate              : Created POST request for "http://localhost:8082/oauth/authorize"
.s.o.c.t.g.i.ImplicitAccessTokenProvider : Encoding and sending form: {response_type=[token], client_id=[themostuntrustedclientid], scope=[read_users write_users], redirect_uri=[http://localhost:8080/api/accessTokenExtractor]}
o.s.web.client.RestTemplate              : POST request for "http://localhost:8082/oauth/authorize" resulted in 302 (null)
o.s.s.web.DefaultRedirectStrategy        : Redirecting to 'http://localhost:8082/login?client_id=themostuntrustedclientid&response_type=token&redirect_uri=http://localhost:8080/api/accessTokenExtractor'

Auth Server:

o.s.s.w.u.matcher.AntPathRequestMatcher  : Request 'POST /oauth/authorize' doesn't match 'GET /**
o.s.s.w.util.matcher.AndRequestMatcher   : Did not match
o.s.s.w.s.HttpSessionRequestCache        : Request not saved as configured RequestMatcher did not match
o.s.s.w.a.ExceptionTranslationFilter     : Calling Authentication entry point.
o.s.s.web.DefaultRedirectStrategy        : Redirecting to 'http://localhost:8082/login'

The implicit client is POSTing for /oauth/authorize, instead of GETting it, and the authserver doesn't store POST requests. The auth server returns a redirect 302 and the implicit client redirects the browser to this url: http://localhost:8082/login?client_id=themostuntrustedclientid&response_type=token&redirect_uri=http://localhost:8080/api/accessTokenExtractor

After successful login the auth server doesn't have a target url so it shows http://localhost:8082/ so it doesn't process any /oauth/authorize request... Where is the problem?

AUTH SERVER CONFIG:

@Configuration
class OAuth2Config extends AuthorizationServerConfigurerAdapter{

    @Autowired
    private AuthenticationManager authenticationManager

    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            .withClient("themostuntrustedclientid")
            .secret("themostuntrustedclientsecret")
            .authorizedGrantTypes("implicit")
            .authorities("ROLE_USER")
            .scopes("read_users", "write_users")
            .accessTokenValiditySeconds(60)     
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(this.authenticationManager);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        //security.checkTokenAccess('hasRole("ROLE_RESOURCE_PROVIDER")')
        security.checkTokenAccess('isAuthenticated()')
    }

}

@Configuration
@EnableWebSecurity
class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().withUser("jose").password("mypassword").roles('USER').and()
                                     .withUser("themostuntrustedclientid").password("themostuntrustedclientsecret").roles('USER')
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .csrf()
            //
            //XXX Si se usa implicit descomentar
            .ignoringAntMatchers("/oauth/authorize")
            .and()
        .authorizeRequests()
            .anyRequest().authenticated()
            .and()
        //.httpBasic()
        .formLogin()
            .loginPage("/login").permitAll()
    }

}

IMPLICIT CLIENT CONFIG:

@Configuration
class OAuth2Config {

    @Value('${oauth.authorize:http://localhost:8082/oauth/authorize}')
    private String authorizeUrl

    @Value('${oauth.token:http://localhost:8082/oauth/token}')
    private String tokenUrl

    @Autowired
    private OAuth2ClientContext oauth2Context

    @Bean
    OAuth2ProtectedResourceDetails resource() {
        ImplicitResourceDetails resource = new ImplicitResourceDetails()
        resource.setAuthenticationScheme(AuthenticationScheme.header)
        resource.setAccessTokenUri(authorizeUrl)
        resource.setUserAuthorizationUri(authorizeUrl);
        resource.setClientId("themostuntrustedclientid")
        resource.setClientSecret("themostuntrustedclientsecret")
        resource.setScope(['read_users', 'write_users'])
        resource
    }

    @Bean
    OAuth2RestTemplate restTemplate() {
        OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(resource(), oauth2Context)
        //restTemplate.setAuthenticator(new ApiConnectOAuth2RequestAuthenticator())
        restTemplate
    }

@Configuration
class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
        auth.eraseCredentials(false)
            .inMemoryAuthentication().withUser("jose").password("mypassword").roles('USER')
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .csrf()
            .ignoringAntMatchers("/accessTokenExtractor")
        .and()
        .authorizeRequests()
        .anyRequest().hasRole('USER')
        .and()
        .formLogin()
            .loginPage("/login").permitAll()
    }

}

Answer 1

The problem was in the SecurityConfig of the Auth server. The implicit client sends automatically a basic Authorization header with the client_id and client_secret. My Auth server was configured to use form login instead of basic auth. I changed it and now it works as expected:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
    .csrf()
        //
        //XXX Si se usa implicit descomentar
        .ignoringAntMatchers("/oauth/authorize")
        .and()
    .authorizeRequests()
        .anyRequest().authenticated()
        .and()
    .httpBasic()
