redis 认证链接方式 redis认证服务器

application.xml

首先引进redis的相关配置 token是要存在这里的

}

下面说一下调用流程 （我随便说的哦 不一定准确）

看一下 /oauth/token经历了啥

总所周知 他这个需要 经历 三个步骤 用户认证 发放令牌 令牌在跑到资源服务器 去校验一下令牌 然后就去访问了

首先 用户认证吧 其实这个框架 主要就是围绕一个过滤器 来进行 就一个一个的进去过滤器进去执行

有三个过滤器

匹配到那个就去执行哪个 第一个过滤器链是oauth/token 那几个默认的端点 第二个就是我们的资源服务器里 第三个就是

那个SecurityConfig 

很明显匹配到了第一个过滤器链

 

在下面这个类里get一下客户端的相关信息  username是前台传的clientId

然后把客户端的信息存入到UserDetails username是前台传clientId 然后后面把前台传过来的客户端密码和后台存的客户端密码比较一下比较的类和方法是

DaoAuthenticationProvider.additionalAuthenticationChecks

 

DaoAuthenticationProvider.class 
protected void additionalAuthenticationChecks(UserDetails userDetails, UsernamePasswordAuthenticationToken authentication) throws AuthenticationException {
        if (authentication.getCredentials() == null) {
            this.logger.debug("Authentication failed: no credentials provided");
            throw new BadCredentialsException(this.messages.getMessage("AbstractUserDetailsAuthenticationProvider.badCredentials", "Bad credentials"));
        } else {
            String presentedPassword = authentication.getCredentials().toString();
           //看见没 这个this.passwordEncoder会把前台传来密码加密一下 这下就知道 为什么必须配置这个Bean了吧
            if (!this.passwordEncoder.matches(presentedPassword, userDetails.getPassword())) {
                this.logger.debug("Authentication failed: password does not match stored value");
                throw new BadCredentialsException(this.messages.getMessage("AbstractUserDetailsAuthenticationProvider.badCredentials", "Bad credentials"));
            }
        }
    }

AbstractSecurityInterceptor.class 
//这个方法很关键 因为在具体取资源的时候这个就是关键最后的一把决定要不要放行
protected InterceptorStatusToken beforeInvocation(Object object) {
        Assert.notNull(object, "Object was null");
        boolean debug = this.logger.isDebugEnabled();
        if (!this.getSecureObjectClass().isAssignableFrom(object.getClass())) {
            throw new IllegalArgumentException("Security invocation attempted for object " + object.getClass().getName() + " but AbstractSecurityInterceptor only configured to support secure objects of type: " + this.getSecureObjectClass());
        } else {
//取出我当前这个访问链接需不需要认证 需要认证的话 需要什么权限
            Collection<ConfigAttribute> attributes = this.obtainSecurityMetadataSource().getAttributes(object);
            if (attributes != null && !attributes.isEmpty()) {
                if (debug) {
                    this.logger.debug("Secure object: " + object + "; Attributes: " + attributes);
                }

                if (SecurityContextHolder.getContext().getAuthentication() == null) {
                    this.credentialsNotFound(this.messages.getMessage("AbstractSecurityInterceptor.authenticationNotFound", "An Authentication object was not found in the SecurityContext"), object, attributes);
                }
                //我当前的链接已经有什么权限 
                Authentication authenticated = this.authenticateIfRequired();

                try {
               //把已经有的和需要有的比较一下看是否放行
                    this.accessDecisionManager.decide(authenticated, object, attributes);
                } catch (AccessDeniedException var7) {
                    this.publishEvent(new AuthorizationFailureEvent(object, attributes, authenticated, var7));
                    throw var7;
                }

                if (debug) {
                    this.logger.debug("Authorization successful");
                }

                if (this.publishAuthorizationSuccess) {
                    this.publishEvent(new AuthorizedEvent(object, attributes, authenticated));
                }

                Authentication runAs = this.runAsManager.buildRunAs(authenticated, object, attributes);
                if (runAs == null) {
                    if (debug) {
                        this.logger.debug("RunAsManager did not change Authentication object");
                    }

                    return new InterceptorStatusToken(SecurityContextHolder.getContext(), false, attributes, object);
                } else {
                    if (debug) {
                        this.logger.debug("Switching to RunAs Authentication: " + runAs);
                    }

                    SecurityContext origCtx = SecurityContextHolder.getContext();
                    SecurityContextHolder.setContext(SecurityContextHolder.createEmptyContext());
                    SecurityContextHolder.getContext().setAuthentication(runAs);
                    return new InterceptorStatusToken(origCtx, true, attributes, object);
                }
            } else if (this.rejectPublicInvocations) {
                throw new IllegalArgumentException("Secure object invocation " + object + " was denied as public invocations are not allowed via this interceptor. This indicates a configuration error because the rejectPublicInvocations property is set to 'true'");
            } else {
                if (debug) {
                    this.logger.debug("Public object - authentication not attempted");
                }

                this.publishEvent(new PublicInvocationEvent(object));
                return null;
            }
        }
    }

 

这个端口有就开始真正的检验客户端权限 以及scope  上面方法的这个

OAuth2AccessToken token = this.getTokenGranter().grant(tokenRequest.getGrantType(), tokenRequest);

就是认证用户方法Token

ResourceOwnerPasswordTokenGranter.class

 protected OAuth2Authentication getOAuth2Authentication(ClientDetails client, TokenRequest tokenRequest) {
        Map<String, String> parameters = new LinkedHashMap(tokenRequest.getRequestParameters());
        String username = (String)parameters.get("username");
        String password = (String)parameters.get("password");
        parameters.remove("password");
        Authentication userAuth = new UsernamePasswordAuthenticationToken(username, password);
        ((AbstractAuthenticationToken)userAuth).setDetails(parameters);

        Authentication userAuth;
        try {
          //去认证了
            userAuth = this.authenticationManager.authenticate(userAuth);
        } catch (AccountStatusException var8) {
            throw new InvalidGrantException(var8.getMessage());
        } catch (BadCredentialsException var9) {
            throw new InvalidGrantException(var9.getMessage());
        }

        if (userAuth != null && userAuth.isAuthenticated()) {
            OAuth2Request storedOAuth2Request = this.getRequestFactory().createOAuth2Request(client, tokenRequest);
         
            return new OAuth2Authentication(storedOAuth2Request, userAuth);
        } else {
            throw new InvalidGrantException("Could not authenticate user: " + username);
        }

这样的话就把用户信息生成token 前面有声明RedisTokenStore这个Bean 他会自动把token信息存入到redis里

再去资源服务器取得时候key+前台传的token能取到就是认证过 没取到就是没有

{
    "access_token": "7dde09dc-12d7-4dc9-b3fc-6521adf51507",
    "token_type": "bearer",
    "refresh_token": "36869a92-278b-4975-b7ea-f7d26ecb84c5",
    "expires_in": 601,
    "scope": "read"
}

于是到这里 用户认证 发放令牌到这里就结束了

然后去资源服务器取值

例如http://10.0.75.1:8083/uua/fegin1/test?access_token=7dde09dc-12d7-4dc9-b3fc-6521adf51507

访问一个受限的资源  其实和上面差不多 一直到 

AbstractSecurityInterceptor.

beforeInvocation的最后一个方法

具体去认证

OAuth2AuthenticationProcessingFilter.class

Authentication authResult = this.authenticationManager.authenticate(authentication);
