#### 序 ####

> 该工具方法主要用于开发者使用腾讯云服务中的**人脸核身**功能进行**人脸与身份证对比认证**操作

#### 实现 ####

*  后端项目引入腾讯云依赖

<dependency>
                <groupId>com.tencentcloudapi</groupId>
                <artifactId>tencentcloud-sdk-java</artifactId>
            </dependency>

*  **获取bizToken**

> 注：目前腾讯云人脸与身份证对比认证由前端实现，但需要一个**bizToken**参数，需要后端提供  
> [官方参考文档][Link 1]

//腾讯云密匙
        private static String secretId = "";
        private static String secretKey = "";
        private static String bizTokenUrl = "faceid.tencentcloudapi.com";
        //人脸核身业务流程RuleID（在人脸核身控制台查看）
        private static String ruleId = "";
    
        public static ResponseData getTencentBizToken() { 
            Credential cred = new Credential(secretId, secretKey);
            HttpProfile httpProfile = new HttpProfile();
            httpProfile.setEndpoint(bizTokenUrl);
            ClientProfile clientProfile = new ClientProfile();
            clientProfile.setHttpProfile(httpProfile);
            FaceidClient client = new FaceidClient(cred, "", clientProfile);
            DetectAuthRequest req = new DetectAuthRequest();
            req.setRuleId(ruleId);
            DetectAuthResponse resp = null;
            try { 
                resp = client.DetectAuth(req);
            } catch (TencentCloudSDKException e) { 
                e.printStackTrace();
            }
            String toJsonString = DetectAuthRequest.toJsonString(resp);
            LogUtil.info("腾讯云获取bizToken接口返回值：{}",toJsonString);
            JSONObject jsonObject = JSON.parseObject(toJsonString);
            return ResponseData.success(jsonObject.getString("BizToken"));
        }

*  前端实现人脸与身份证对比认证（实现步骤略）

> 1.  前端实现用户身份证上传至腾讯云
> 2.  前端上传活体人脸照至腾讯云
> 3.  腾讯云进行人脸对比
> 4.  **对比成功则返回对比用户的专属bizToken**

*  **获取人脸对比成功的用户信息**

> 可用于前端对比成功调用接口，将用户信息存储到数据库  
> [官方参考文档][Link 2]

/** * * @param bizToken 用户专属bizToken * @return */
     public static JSONObject  getTencentCompare(String bizToken){ 
            try{ 
                Credential cred = new Credential(secretId, secretKey);
                HttpProfile httpProfile = new HttpProfile();
                httpProfile.setEndpoint("faceid.tencentcloudapi.com");
                ClientProfile clientProfile = new ClientProfile();
                clientProfile.setHttpProfile(httpProfile);
                FaceidClient client = new FaceidClient(cred, "", clientProfile);
                GetDetectInfoRequest req = new GetDetectInfoRequest();
                req.setBizToken(bizToken);
                req.setInfoType("0");
                req.setRuleId(ruleId );
                GetDetectInfoResponse resp = client.GetDetectInfo(req);
                String resultInfo = GetDetectInfoResponse.toJsonString(resp);
                if(StringUtils.isEmpty(resultInfo)){ 
                    log.error("身份信息请求失败--------------");
                    return null;
                }
                JSONObject jsonObject = JSONObject.parseObject(resultInfo);
                String detectInfo = jsonObject.getString("DetectInfo");
                if(org.apache.commons.lang.StringUtils.isBlank(detectInfo)){ 
                    log.error("身份信息获取失败--------------");
                    return null;
                }
                JSONObject jsonObject2 = JSONObject.parseObject(detectInfo);
                if(jsonObject2 == null){ 
                   return null;
                }
                return jsonObject2;
            } catch (TencentCloudSDKException e) { 
                e.printStackTrace();
                return null;
            }
        }

搞定。
