Spring Security源码分析三：Spring Social实现QQ社交登录

系列文章：

社交登录又称作社会化登录（Social Login），是指网站的用户可以使用腾讯QQ、人人网、开心网、新浪微博、搜狐微博、腾讯微博、淘宝、豆瓣、MSN、Google等社会化媒体账号登录该网站。

OAuth2.0的认证流程示意图

请求第三方应用
第三方应用将用户请求导向服务提供商
用户同意授权
服务提供商返回code
client根据code去服务提供商换取令牌
返回令牌
获取用户信息

在标准的OAuth2协议中，1-6步都是固定，只有最后一步，不通的服务提供商返回的用户信息是不同的。Spring Social已经为我们封装好了1-6步。

使用Spring Social

准备工作

在qq互联申请个人开发者，获得appId和appKey或者使用 SpringForAll贡献出来的
配置本地host 添加 127.0.0.1 www.ictgu.cn
数据库执行以下sql

create table UserConnection (userId varchar(255) not null,
 providerId varchar(255) not null,
 providerUserId varchar(255),
 rank int not null,
 displayName varchar(255),
 profileUrl varchar(512),
 imageUrl varchar(512),
 accessToken varchar(512) not null,
 secret varchar(512),
 refreshToken varchar(512),
 expireTime bigint,
 primary key (userId, providerId, providerUserId));
create unique index UserConnectionRank on UserConnection(userId, providerId, rank);

项目端口设置为80端口

引入Spring Social 模块

模块描述spring-social-core提供社交连接框架和OAuth 客户端支持spring-social-config提供Java 配置spring-social-security社交安全的一些支持spring-social-web管理web应用程序的连接

目录结构

‘api’ 定义api绑定的公共接口
‘config’ qq的一些配置信息
‘connect’与服务提供商建立连接所需的一些类。

定义返回用户信息接口

public interface QQ {
    /**
     * 获取用户信息
     * @return
     */
    QQUserInfo getUserInfo();
}

实现返回用户信息接口

@Slf4j
public class QQImpl extends AbstractOAuth2ApiBinding implements QQ {

    //http://wiki.connect.qq.com/openapi%E8%B0%83%E7%94%A8%E8%AF%B4%E6%98%8E_oauth2-0
    private static final String QQ_URL_GET_OPENID = "https://graph.qq.com/oauth2.0/me?access_token=%s";
    //http://wiki.connect.qq.com/get_user_info(access_token由父类提供)
    private static final String QQ_URL_GET_USER_INFO = "https://graph.qq.com/user/get_user_info?oauth_consumer_key=%s&openid=%s";
    /**
     * appId 配置文件读取
     */
    private String appId;
    /**
     * openId 请求QQ_URL_GET_OPENID返回
     */
    private String openId;
    /**
     * 工具类
     */
    private ObjectMapper objectMapper = new ObjectMapper();

    /**
     * 构造方法获取openId
     */
    public QQImpl(String accessToken, String appId) {
        //access_token作为查询参数来携带。
        super(accessToken, TokenStrategy.ACCESS_TOKEN_PARAMETER);

        this.appId = appId;

        String url = String.format(QQ_URL_GET_OPENID, accessToken);
        String result = getRestTemplate().getForObject(url, String.class);

        log.info("【QQImpl】 QQ_URL_GET_OPENID={} result={}", QQ_URL_GET_OPENID, result);

        this.openId = StringUtils.substringBetween(result, "\"openid\":\"", "\"}");
    }

    @Override
    public QQUserInfo getUserInfo() {
        String url = String.format(QQ_URL_GET_USER_INFO, appId, openId);
        String result = getRestTemplate().getForObject(url, String.class);

        log.info("【QQImpl】 QQ_URL_GET_USER_INFO={} result={}", QQ_URL_GET_USER_INFO, result);

        QQUserInfo userInfo = null;
        try {
            userInfo = objectMapper.readValue(result, QQUserInfo.class);
            userInfo.setOpenId(openId);
            return userInfo;
        } catch (Exception e) {
            throw new RuntimeException("获取用户信息失败", e);
        }
    }
}

QQOAuth2Template处理qq返回的令牌信息

@Slf4j
public class QQOAuth2Template extends OAuth2Template {
    public QQOAuth2Template(String clientId, String clientSecret, String authorizeUrl, String accessTokenUrl) {
        super(clientId, clientSecret, authorizeUrl, accessTokenUrl);
        setUseParametersForClientAuthentication(true);
    }

    @Override
    protected AccessGrant postForAccessGrant(String accessTokenUrl, MultiValueMap<String, String> parameters) {
        String responseStr = getRestTemplate().postForObject(accessTokenUrl, parameters, String.class);

        log.info("【QQOAuth2Template】获取accessToke的响应：responseStr={}" + responseStr);

        String[] items = StringUtils.splitByWholeSeparatorPreserveAllTokens(responseStr, "&");
        //http://wiki.connect.qq.com/使用authorization_code获取access_token
        //access_token=FE04************************CCE2&expires_in=7776000&refresh_token=88E4************************BE14
        String accessToken = StringUtils.substringAfterLast(items[0], "=");
        Long expiresIn = new Long(StringUtils.substringAfterLast(items[1], "="));
        String refreshToken = StringUtils.substringAfterLast(items[2], "=");

        return new AccessGrant(accessToken, null, refreshToken, expiresIn);
    }


    /**
     * 坑，日志debug模式才打印出来 处理qq返回的text/html 类型数据
     *
     * @return
     */
    @Override
    protected RestTemplate createRestTemplate() {
        RestTemplate restTemplate = super.createRestTemplate();
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter(Charset.forName("UTF-8")));
        return restTemplate;
    }
}

QQServiceProvider连接服务提供商

public class QQServiceProvider extends AbstractOAuth2ServiceProvider<QQ> {

    /**
     * 获取code
     */
    private static final String QQ_URL_AUTHORIZE = "https://graph.qq.com/oauth2.0/authorize";
    /**
     * 获取access_token 也就是令牌
     */
    private static final String QQ_URL_ACCESS_TOKEN = "https://graph.qq.com/oauth2.0/token";
    private String appId;

    public QQServiceProvider(String appId, String appSecret) {
        super(new QQOAuth2Template(appId, appSecret, QQ_URL_AUTHORIZE, QQ_URL_ACCESS_TOKEN));
        this.appId = appId;
    }

    @Override
    public QQ getApi(String accessToken) {

        return new QQImpl(accessToken, appId);
    }
}

QQConnectionFactory连接服务提供商的工厂类

public class QQConnectionFactory extends OAuth2ConnectionFactory<QQ> {

    public QQConnectionFactory(String providerId, String appId, String appSecret) {
        super(providerId, new QQServiceProvider(appId, appSecret), new QQAdapter());
    }
}

QQAdapter 适配spring Social默认的返回信息

public class QQAdapter implements ApiAdapter<QQ> {
    @Override
    public boolean test(QQ api) {
        return true;
    }

    @Override
    public void setConnectionValues(QQ api, ConnectionValues values) {
        QQUserInfo userInfo = api.getUserInfo();

        values.setProviderUserId(userInfo.getOpenId());//openId 唯一标识
        values.setDisplayName(userInfo.getNickname());
        values.setImageUrl(userInfo.getFigureurl_qq_1());
        values.setProfileUrl(null);
    }

    @Override
    public UserProfile fetchUserProfile(QQ api) {
        return null;
    }

    @Override
    public void updateStatus(QQ api, String message) {

    }
}

SocialConfig 社交配置主类

@Configuration
@EnableSocial
public class SocialConfig extends SocialConfigurerAdapter {

    /**
     * 社交登录配类
     *
     * @return
     */
    @Bean
    public SpringSocialConfigurer merryyouSocialSecurityConfig() {
        String filterProcessesUrl = SecurityConstants.DEFAULT_SOCIAL_QQ_PROCESS_URL;
        MerryyouSpringSocialConfigurer configurer = new MerryyouSpringSocialConfigurer(filterProcessesUrl);
        return configurer;
    }

    /**
     * 处理注册流程的工具类
     * @param factoryLocator
     * @return
     */
    @Bean
    public ProviderSignInUtils providerSignInUtils(ConnectionFactoryLocator factoryLocator) {
        return new ProviderSignInUtils(factoryLocator, getUsersConnectionRepository(factoryLocator));
    }

}

QQAuthConfig 针对qq返回结果的一些操作

@Configuration
public class QQAuthConfig extends SocialAutoConfigurerAdapter {

    @Autowired
    private DataSource dataSource;

    @Autowired
    private ConnectionSignUp myConnectionSignUp;

    @Override
    protected ConnectionFactory<?> createConnectionFactory() {
        return new QQConnectionFactory(SecurityConstants.DEFAULT_SOCIAL_QQ_PROVIDER_ID, SecurityConstants.DEFAULT_SOCIAL_QQ_APP_ID, SecurityConstants.DEFAULT_SOCIAL_QQ_APP_SECRET);
    }

    @Override
    public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
        JdbcUsersConnectionRepository repository = new JdbcUsersConnectionRepository(dataSource,
                connectionFactoryLocator, Encryptors.noOpText());
        if (myConnectionSignUp != null) {
            repository.setConnectionSignUp(myConnectionSignUp);
        }
        return repository;
    }
}

MerryyouSpringSocialConfigurer自定义登录和注册连接

public class MerryyouSpringSocialConfigurer extends SpringSocialConfigurer {

    private String filterProcessesUrl;

    public MerryyouSpringSocialConfigurer(String filterProcessesUrl) {
        this.filterProcessesUrl = filterProcessesUrl;
    }

    @Override
    protected <T> T postProcess(T object) {
        SocialAuthenticationFilter filter = (SocialAuthenticationFilter) super.postProcess(object);
        filter.setFilterProcessesUrl(filterProcessesUrl);
        filter.setSignupUrl("/register");
        return (T) filter;
    }
}

开启SocialAuthenticationFilter过滤器

@Autowired
    private SpringSocialConfigurer merryyouSpringSocialConfigurer;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
                .formLogin()//使用表单登录，不再使用默认httpBasic方式
                .loginPage(SecurityConstants.DEFAULT_UNAUTHENTICATION_URL)//如果请求的URL需要认证则跳转的URL
                .loginProcessingUrl(SecurityConstants.DEFAULT_SIGN_IN_PROCESSING_URL_FORM)//处理表单中自定义的登录URL
                .and()
                .apply(merryyouSpringSocialConfigurer)
                .and()
                .authorizeRequests().antMatchers(SecurityConstants.DEFAULT_UNAUTHENTICATION_URL,
                SecurityConstants.DEFAULT_SIGN_IN_PROCESSING_URL_FORM,
                SecurityConstants.DEFAULT_REGISTER_URL,
                "/register",
                "/social/info",
                "/**/*.js",
                "/**/*.css",
                "/**/*.jpg",
                "/**/*.png",
                "/**/*.woff2",
                "/code/image")
                .permitAll()//以上的请求都不需要认证
                //.antMatchers("/").access("hasRole('USER')")
                .and()
                .csrf().disable()//关闭csrd拦截
        ;
        //安全模块单独配置
        authorizeConfigProvider.config(http.authorizeRequests());
    }

效果如下：
