具有隐式客户端和csrf保护的OAuth2

我有一个我想用OAuth2保护的API。我已经使用密码grant_type进行了虚拟测试,一切正常。我可以请求令牌,使用它访问安全端点等。服务器充当授权和资源服务器。

后来我读到我应该使用隐式grant_type,因为客户端将是一个javascript应用程序。

我的客户端配置如下:

@Override
public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {// @formatter:off
clients
    .inMemory().withClient("web")
    .redirectUris("http://localhost:3000")
    .secret("secret")
    .authorizedGrantTypes("implicit", "refresh_token").scopes("read", "write")
    .accessTokenValiditySeconds(3600).refreshTokenValiditySeconds(2592000);
}

如果我尝试像这样访问端点: http://localhost:8080/oauth/authorize?grant_type=implicit&client_id=web&response_type=token&redirect_uri=http%3A%2F%2Flocalhost%3A3000

我明白了:

{
  "timestamp": 1464136960414,
  "status": 403,
  "error": "Forbidden",
  "message": "Expected CSRF token not found. Has your session expired?",
  "path": "/oauth/authorize"
}

如果我第一次调用API,如何拥有CSRF令牌? 如果(仅用于测试)我禁用csrf然后我得到这个:

{
  "timestamp": 1464136840865,
  "status": 403,
  "error": "Forbidden",
  "exception": "org.springframework.security.authentication.InsufficientAuthenticationException",
  "message": "Access Denied",
  "path": "/oauth/authorize"
}

使用密码grant_type设置客户端我可以进行此调用,一切正常: http://localhost:8080/oauth/token?grant_type=password&username=test&password=123 并添加具有客户端ID / secret的Authorization Basic标头。

为了澄清,我们的想法是拥有这个独特的可信客户端。因此,用户只需输入登录名/密码,而无需要求用户授予对该应用的访问权限。

对不起,如果这是一个愚蠢的问题。我一直在阅读我能找到的所有东西,但似乎无法取得进展。

谢谢!

My Spring Security Config:

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

  @Autowired
  private MongoDBAuthenticationProvider authenticationProvider;

  @Autowired
  public void globalUserDetails(final AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(authenticationProvider);
  }

  @Override
  @Bean
  public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
  }
}

我的OAuth配置:

@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServerConfig extends     AuthorizationServerConfigurerAdapter {

  @Autowired
  @Qualifier("authenticationManagerBean")
  private AuthenticationManager authenticationManager;

  @Override
  public void configure(final AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()").checkTokenAccess("isAuthenticated()");
  }

  @Override
  public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {
    clients
    .inMemory().withClient("web")
    .redirectUris("http://localhost:3000")
    .secret("secret")
    .authorizedGrantTypes("implicit", "refresh_token").scopes("read", "write")
    .accessTokenValiditySeconds(3600).refreshTokenValiditySeconds(2592000);
  }

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

服务器中的异常:

当您为授权服务器调用隐式授权类型时,您必须包含一个不透明的字符串值作为状态参数以避免csrf攻击。因此,授权服务器的请求URL将如下所示:

http://localhost:8080/oauth/authorize?grant_type=implicit&client_id=web&response_type=token&redirect_uri=http%3A%2F%2Flocalhost%3A3000&state=123abc

您在state参数中提到的值将在响应中回显给您。然后,将回显值与初始值进行比较,以确认没有发生csrf攻击。
