15、Spring Authorization Server入门-分离授权确认与设备码校验页面

分类：Spring Authorization Server    2024-02-03    阅读(222)

2023-12-01修改：在session-data-redis(Github)分支中添加了基于spring-session-data-redis的实现，无需借助nonceId来保持认证状态，该分支已去除所有nonceId相关内容，需要注意的是axios在初始化时需要添加配置withCredentials: true，让请求携带cookie。当然一些响应json的处理还是使用下方的内容。

前言

这篇文章中只分离了登录页面，鉴于部分读者好奇授权确认页面分离的实现，就实现一下授权确认页面的分离，
同时设备码流程的授权确认页面与授权码流程的授权确认页面是同一个，这里也需要兼容一下，
还有就是设备码流程中有一个校验设备码的页面，这里也需要分离出来。

前文中有提到，在前后端分离的模式下，在页面发起的请求需要响应json不能重定向了，所以需要修改相关接口调用成功后响应json。话不多说，直接上代码。

编码

需要修改的内容

1、 重定向至授权确认页面时直接携带相关参数重定向至前端项目中；
2、 提供接口查询登录用户在发起授权的客户端中相关scope信息；
3、 重定向至设备码校验页面时携带当前sessionId(nonceId)重定向至前端项目中；
4、 编写授权确认失败处理类，在调用确认授权接口失败时响应json；
5、 编写授权成功处理类，在调用授权确认接口成功时响应json；
6、 编写校验设备码成功响应类，在校验设备码成功后响应json；
7、 修改重定向至登录页面处理，兼容在请求校验设备码时登录信息过期处理；
8、 将以上内容添加至认证服务配置中；
9、 前端项目中编写授权确认、设备码校验、设备码校验成功页面；

重定向至授权确认页面时直接携带相关参数重定向至前端项目中

在AuthorizationController中编写/oauth2/consent/redirect接口，借助认证服务跳转至前端的，跳转时携带sessionId保持登录状态

@SneakyThrows
@ResponseBody
@GetMapping(value = "/oauth2/consent/redirect")
public Result<String> consentRedirect(HttpSession session,
                                      HttpServletRequest request,
                                      HttpServletResponse response,
                                      @RequestParam(OAuth2ParameterNames.SCOPE) String scope,
                                      @RequestParam(OAuth2ParameterNames.STATE) String state,
                                      @RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,
                                      @RequestHeader(name = NONCE_HEADER_NAME, required = false) String nonceId,
                                      @RequestParam(name = OAuth2ParameterNames.USER_CODE, required = false) String userCode) {

    // 携带当前请求参数与nonceId重定向至前端页面
    UriComponentsBuilder uriBuilder = UriComponentsBuilder
            .fromUriString(CONSENT_PAGE_URI)
            .queryParam(OAuth2ParameterNames.SCOPE, UriUtils.encode(scope, StandardCharsets.UTF_8))
            .queryParam(OAuth2ParameterNames.STATE, UriUtils.encode(state, StandardCharsets.UTF_8))
            .queryParam(OAuth2ParameterNames.CLIENT_ID, clientId)
            .queryParam(OAuth2ParameterNames.USER_CODE, userCode)
            .queryParam(NONCE_HEADER_NAME, ObjectUtils.isEmpty(nonceId) ? session.getId() : nonceId);

    String uriString = uriBuilder.build(Boolean.TRUE).toUriString();
    if (ObjectUtils.isEmpty(userCode) || !UrlUtils.isAbsoluteUrl(DEVICE_ACTIVATE_URI)) {

        // 不是设备码模式或者设备码验证页面不是前后端分离的，无需返回json，直接重定向
        redirectStrategy.sendRedirect(request, response, uriString);
        return null;
    }
    // 兼容设备码，需响应JSON，由前端进行跳转
    return Result.success(uriString);
}

提供接口查询登录用户在发起授权的客户端中相关scope信息

在AuthorizationController中编写/oauth2/consent/parameters接口

@ResponseBody
@GetMapping(value = "/oauth2/consent/parameters")
public Result<Map<String, Object>> consentParameters(Principal principal,
                                                     @RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,
                                                     @RequestParam(OAuth2ParameterNames.SCOPE) String scope,
                                                     @RequestParam(OAuth2ParameterNames.STATE) String state,
                                                     @RequestParam(name = OAuth2ParameterNames.USER_CODE, required = false) String userCode) {

    // 获取consent页面所需的参数
    Map<String, Object> consentParameters = getConsentParameters(scope, state, clientId, userCode, principal);

    return Result.success(consentParameters);
}

修改/oauth2/consent接口

@GetMapping(value = "/oauth2/consent")
public String consent(Principal principal, Model model,
                      @RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,
                      @RequestParam(OAuth2ParameterNames.SCOPE) String scope,
                      @RequestParam(OAuth2ParameterNames.STATE) String state,
                      @RequestParam(name = OAuth2ParameterNames.USER_CODE, required = false) String userCode) {

    // 获取consent页面所需的参数
    Map<String, Object> consentParameters = getConsentParameters(scope, state, clientId, userCode, principal);
    // 转至model中，让框架渲染页面
    consentParameters.forEach(model::addAttribute);

    return "consent";
}

编写公共方法getConsentParameters

/**
 * 根据授权确认相关参数获取授权确认与未确认的scope相关参数
 *
 * @param scope     scope权限
 * @param state     state
 * @param clientId  客户端id
 * @param userCode  设备码授权流程中的用户码
 * @param principal 当前认证信息
 * @return 页面所需数据
 */
private Map<String, Object> getConsentParameters(String scope,
                                                 String state,
                                                 String clientId,
                                                 String userCode,
                                                 Principal principal) {

    // Remove scopes that were already approved
    Set<String> scopesToApprove = new HashSet<>();
    Set<String> previouslyApprovedScopes = new HashSet<>();
    RegisteredClient registeredClient = this.registeredClientRepository.findByClientId(clientId);
    if (registeredClient == null) {

        throw new RuntimeException("客户端不存在");
    }
    OAuth2AuthorizationConsent currentAuthorizationConsent =
            this.authorizationConsentService.findById(registeredClient.getId(), principal.getName());
    Set<String> authorizedScopes;
    if (currentAuthorizationConsent != null) {

        authorizedScopes = currentAuthorizationConsent.getScopes();
    } else {

        authorizedScopes = Collections.emptySet();
    }
    for (String requestedScope : StringUtils.delimitedListToStringArray(scope, " ")) {

        if (OidcScopes.OPENID.equals(requestedScope)) {

            continue;
        }
        if (authorizedScopes.contains(requestedScope)) {

            previouslyApprovedScopes.add(requestedScope);
        } else {

            scopesToApprove.add(requestedScope);
        }
    }

    Map<String, Object> parameters = new HashMap<>(7);
    parameters.put("clientId", registeredClient.getClientId());
    parameters.put("clientName", registeredClient.getClientName());
    parameters.put("state", state);
    parameters.put("scopes", withDescription(scopesToApprove));
    parameters.put("previouslyApprovedScopes", withDescription(previouslyApprovedScopes));
    parameters.put("principalName", principal.getName());
    parameters.put("userCode", userCode);
    if (StringUtils.hasText(userCode)) {

        parameters.put("requestURI", "/oauth2/device_verification");
    } else {

        parameters.put("requestURI", "/oauth2/authorize");
    }
    return parameters;
}

重定向至设备码校验页面时携带当前sessionId(nonceId)重定向至前端项目中

在AuthorizationController中编写/activate/redirect接口，由认证服务重定向，携带sessionId以保持登录状态

@GetMapping("/activate/redirect")
public String activateRedirect(HttpSession session,
                               @RequestParam(value = "user_code", required = false) String userCode) {

    UriComponentsBuilder uriBuilder = UriComponentsBuilder
            .fromUriString(DEVICE_ACTIVATE_URI)
            .queryParam("userCode", userCode)
            .queryParam(NONCE_HEADER_NAME, session.getId());
    return "redirect:" + uriBuilder.build(Boolean.TRUE).toUriString();
}

编写授权确认失败处理类，在调用确认授权接口失败时响应json

    @Override

        // 获取当前认证信息
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        // 获取具体的异常
        OAuth2AuthenticationException authenticationException = (OAuth2AuthenticationException) exception;
        OAuth2Error error = authenticationException.getError();
        // 异常信息
        String message;
        if (authentication == null) {

            message = "登录已失效";
        } else {

            // 第二次点击“拒绝”会因为之前取消时删除授权申请记录而找不到对应的数据，导致抛出 [invalid_request] OAuth 2.0 Parameter: state
            message = error.toString();
        }

        // 授权确认页面提交的请求，因为授权申请与授权确认提交公用一个过滤器，这里判断一下
        if (request.getMethod().equals(HttpMethod.POST.name()) && UrlUtils.isAbsoluteUrl(CONSENT_PAGE_URI)) {

            // 写回json异常
            Result<Object> result = Result.error(HttpStatus.BAD_REQUEST.value(), message);
            response.setCharacterEncoding(StandardCharsets.UTF_8.name());
            response.setContentType(MediaType.APPLICATION_JSON_VALUE);
            response.getWriter().write(JsonUtils.objectCovertToJson(result));
            response.getWriter().flush();
        } else {

            // 在地址栏输入授权申请地址或设备码流程的验证地址错误(user_code错误)
            response.sendError(HttpStatus.BAD_REQUEST.value(), error.toString());

到此为止编码就结束了

最后

因为理论部分在之前的文章中已经讲过了，这次就没写理论了，直接贴了一大堆的代码，本次代码写的比较仓促，测试的也不是很全面，如果发现有什么问题可以在评论区留言。
