【Spring Security OAuth2笔记系列】- App认证框架- 令牌配置

令牌配置

接下来的内容是：

• 基本的Token参数配置
• 使用jwt替换默认的token
• 扩展和解析jwt的信息

token 的处理在认证服务器处理的。之前已经配置了资源服务器，现在来自定义认证服务器

spirng boot 2 的自动配置文件和1.5的不一样
直接跟着视频走是不会成功的，原因如下

OAuth2AuthorizationServerConfiguration 类是 @EnableAuthorizationServer 的自动配置类；
如果我们 继承了 AuthorizationServerConfigurerAdapter，那么该类将不会被初始化，认证服务器将不能正常工作
(看源码中的条件注解声明得知)

这是根据自动配置类简化而来的配置。正常使用

package cn.mrcode.imooc.springsecurity.securityapp;

/**
 * ${desc}
 * @author zhuqiang
 * @version 1.0.1 2018/8/7 10:52
 * @date 2018/8/7 10:52
 * @since 1.0
 */
@Configuration
@EnableAuthorizationServer
public class MyAuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    private final AuthenticationManager authenticationManager;
//    @Autowired
//    private PasswordEncoder passwordEncoder;

    public MyAuthorizationServerConfig(
            AuthenticationConfiguration authenticationConfiguration) throws Exception {
        this.authenticationManager = authenticationConfiguration.getAuthenticationManager();
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("myid")
                .secret("myid")
                .redirectUris("http://example.com", "http://ora.com")
                .and()
                .withClient("myid2")
                .secret("myid2")
                .redirectUris("http://example.com", "localhost:8080")
                .authorizedGrantTypes("refresh_token", "password")
                .accessTokenValiditySeconds(7200)
                .scopes("all", "read", "write");
    }

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

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        // 这里使用什么密码需要 根据上面配置client信息里面的密码类型决定
        // 目前上面配置的是无加密的密码
        security.passwordEncoder(NoOpPasswordEncoder.getInstance());
    }
}

抽成配置

下面记录下一些注意的地方

yml中数组和对象嵌套的写法如下：

imooc:
  security:
    oauth2:
      clients:
        -
          clientId: myid
          clientSecret: myid
          redirectUris:
            - "http://example.com"
            - "http://ora.com"
          accessTokenValiditySeconds: 0
        -
          clientId: myid2
          clientSecret: myid2
          authorizedGrantTypes: ["refresh_token", "password"]
          redirectUris:
            - "http://example.com"
            - "localhost:8080"
          scopes: ["all", "read", "write"]
          accessTokenValiditySeconds: 7200

配置类对应,注意看下面的数组。都是默认为空数组，这样不会导致代码中npe

public class OAuth2Properties {
    private OAuth2ClientProperties[] clients = {};

public class OAuth2ClientProperties {
    private String clientId;
    private String clientSecret;
    private String[] authorizedGrantTypes = {};
    private String[] redirectUris = {}; // 信任的回调域
    private String[] scopes = {};
    private int accessTokenValiditySeconds; // token有效期

配置使用的地方

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    InMemoryClientDetailsServiceBuilder inMemory = clients.inMemory();
    OAuth2ClientProperties[] clientsInCustom = securityProperties.getOauth2().getClients();
    for (OAuth2ClientProperties p : clientsInCustom) {
        inMemory.withClient(p.getClientId())
                .secret(p.getClientSecret())
                .redirectUris(p.getRedirectUris())
                .authorizedGrantTypes(p.getAuthorizedGrantTypes())
                .accessTokenValiditySeconds(p.getAccessTokenValiditySeconds())
                .scopes(p.getScopes());
    }
    logger.info(Arrays.toString(clientsInCustom));
}

tokenStore 使用redis来存储

上面的配置都是使用的内存来存储令牌信息；令牌的存储和获取比较频繁，为了能持久化。使用redis

在认证服务配置类中配置tokenStore即可

cn.mrcode.imooc.springsecurity.securityapp.MyAuthorizationServerConfig

@Autowired(required = false)
public TokenStore tokenStore;

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

TokenStore 需要使用的地方初始化对象，也就是app中

package cn.mrcode.imooc.springsecurity.securityapp;

import cn.mrcode.imooc.springsecurity.securitycore.MyRedisTokenStore;

@Configuration
public class TokenStoreConfig {
    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

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

注意在spring boot 2.0.4 中；使用默认的 RedisTokenStore 在存储的时候会出现异常；

解决方案：把RedisTokenStore的代码完全copy一份，然后把 storeAccessToken 方法中调用
conn.set的代码全部缓存 conn.stringCommands().set

@Override
   public void storeAccessToken(OAuth2AccessToken token, OAuth2Authentication authentication) {
       byte[] serializedAccessToken = serialize(token);
       byte[] serializedAuth = serialize(authentication);
       byte[] accessKey = serializeKey(ACCESS + token.getValue());
       byte[] authKey = serializeKey(AUTH + token.getValue());
       byte[] authToAccessKey = serializeKey(AUTH_TO_ACCESS + authenticationKeyGenerator.extractKey(authentication));
       byte[] approvalKey = serializeKey(UNAME_TO_ACCESS + getApprovalKey(authentication));
       byte[] clientId = serializeKey(CLIENT_ID_TO_ACCESS + authentication.getOAuth2Request().getClientId());

       RedisConnection conn = getConnection();
       try {
           conn.openPipeline();
           // 这里 set的时候，子类都不支持存储自己数组
           conn.stringCommands().set(accessKey, serializedAccessToken);

一篇不错的redis的配置文章：https://majing.io/posts/10000020931206
切换到jedis中还是会出现一样的错误，所以不用测试jedis了；就是依赖包不兼容的问题，
