发送验证码的Controller
首先我们需要创建一个发送验证码的 Controller, 至于如何实现,这里就不多说了,大家都会的,本篇重点说明验证部分.
【注意】在认证服务器上增加自己的 Controller, 默认情况下访问是返回403,有两种办法解决:
把认证服务器也配制为资源服务器,既: 它既是认证服务器,也是资源服务器.并配制新增的Controller为任何人都能访问
关闭认证服务器的 csrf.
由于我在认证服务器上增加的都是认证相关的功能,任何人都能访问,不需要资源保护,所以我选择了第二种方法.
关闭认证服务器的 csrf
在配制认证服务器的时候,我们创建过一个org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter 的子类用于安全配制. 如果你当时没有配制,增加一个就行.
import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.authentication.AuthenticationManager;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;import org.springframework.security.crypto.password.PasswordEncoder;@Configuration@EnableWebSecuritypublic class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable(); // 关闭 csrf
}
}增加短信验证码的 TokenGranter
参考 org.springframework.security.oauth2.provider.password.ResourceOwnerPasswordTokenGranter 的代码
import org.apache.commons.lang3.StringUtils;import org.springframework.core.env.Environment;import org.springframework.security.authentication.AbstractAuthenticationToken;import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;import org.springframework.security.core.Authentication;import org.springframework.security.core.userdetails.UserDetails;import org.springframework.security.core.userdetails.UserDetailsChecker;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.oauth2.common.exceptions.InvalidGrantException;import org.springframework.security.oauth2.provider.ClientDetails;import org.springframework.security.oauth2.provider.ClientDetailsService;import org.springframework.security.oauth2.provider.OAuth2Authentication;import org.springframework.security.oauth2.provider.OAuth2Request;import org.springframework.security.oauth2.provider.OAuth2RequestFactory;import org.springframework.security.oauth2.provider.TokenRequest;import org.springframework.security.oauth2.provider.token.AbstractTokenGranter;import org.springframework.security.oauth2.provider.token.AuthorizationServerTokenServices;
public class SMSCodeTokenGranter extends AbstractTokenGranter {
private static final String GRANT_TYPE = "sms_code";
public SMSCodeLoginTokenGranter(AuthorizationServerTokenServices tokenServices,
ClientDetailsService clientDetailsService, OAuth2RequestFactory requestFactory) { super(tokenServices, clientDetailsService, requestFactory, GRANT_TYPE);
}
@Override
protected OAuth2Authentication getOAuth2Authentication(ClientDetails client,
TokenRequest tokenRequest) {
Map<String, String> parameters = new LinkedHashMap<String, String>(tokenRequest.getRequestParameters()); String userMobileNo = parameters.get("username"); //客户端提交的用户名
String smscode = parameters.get("smscode"); //客户端提交的验证码
// 从库里查用户
UserDetails user = 从库里查找用户的代码略; if(user == null) { throw new InvalidGrantException("用户不存在");
}
验证用户状态(是否警用等),代码略 // 验证验证码
String smsCodeCached = 获取服务中保存的用户验证码,代码略.一般我们是在生成好后放到缓存中 if(StringUtils.isBlank(smsCodeCached)) { throw new InvalidGrantException("用户没有发送验证码");
} if(!smscode.equals(smsCodeCached)) { throw new InvalidGrantException("验证码不正确");
}else {
验证通过后从缓存中移除验证码,代码略
}
Authentication userAuth = new UsernamePasswordAuthenticationToken(user, null, user.getAuthorities()); // 关于user.getAuthorities(): 我们的自定义用户实体是实现了
// org.springframework.security.core.userdetails.UserDetails 接口的, 所以有 user.getAuthorities()
// 当然该参数传null也行
((AbstractAuthenticationToken) userAuth).setDetails(parameters);
OAuth2Request storedOAuth2Request = getRequestFactory().createOAuth2Request(client, tokenRequest);
return new OAuth2Authentication(storedOAuth2Request, userAuth);
}
}把 SMSCodeTokenGranter 加入到 CompositeTokenGranter 需要的 List<TokenGranter> 中
在上一篇中我们修改了 OAuth2AuthorizationServerConfig类,现在继续修改:
我们在 getDefaultTokenGranters 方法中加入:
tokenGranters.add(new SMSCodeLoginTokenGranter(tokenServices, clientDetails, requestFactory, userDetailsService));
getDefaultTokenGranters 的完整代码:
private List<TokenGranter> getDefaultTokenGranters() {
ClientDetailsService clientDetails = clientDetailsService();
AuthorizationServerTokenServices tokenServices = tokenServices();
AuthorizationCodeServices authorizationCodeServices = authorizationCodeServices();
OAuth2RequestFactory requestFactory = requestFactory(); List<TokenGranter> tokenGranters = new ArrayList<TokenGranter>();
tokenGranters.add(new AuthorizationCodeTokenGranter(tokenServices,
authorizationCodeServices, clientDetails, requestFactory));
tokenGranters.add(new RefreshTokenGranter(tokenServices, clientDetails, requestFactory));
ImplicitTokenGranter implicit = new ImplicitTokenGranter(tokenServices, clientDetails,
requestFactory);
tokenGranters.add(implicit);
tokenGranters.add( new ClientCredentialsTokenGranter(tokenServices, clientDetails, requestFactory)); if (authenticationManager != null) {
tokenGranters.add(new ResourceOwnerPasswordTokenGranter(authenticationManager,
tokenServices, clientDetails, requestFactory));
}
tokenGranters.add(new SMSCodeLoginTokenGranter(tokenServices, clientDetails, requestFactory, userDetailsService)); return tokenGranters;
}其他代码不用修改
如何使用我们新增的短信验证码方式?
我们调用 /oauth/token 进行认证的时候,有一个 grant_type 参数,我们把它的值改为 sms_code
password 参数可以不要了,新增一个 smscode 参数
当然,上面的 "sms_code" 和 "smscode" 也是可以修改的:
"sms_code" 对应 SMSCodeTokenGranter 中的静态常量 GRANT_TYPE
"smscode" 对应 SMSCodeTokenGranter.getOAuth2Authentication 方法中的 parameters.get("smscode");
