一、效果图
后台获取的数据：
我们去百度智能云人脸库查看，正是这个用户
项目源码已经上传到github，整个项目是springboot项目，下载下来就可以体验了。本工程对百度人脸识别接口进行了封装，理解简单。
下载地址：/chenxingxing6/mycloud-admin
二、注册百度云智能云
/?from=console
具体怎么操作，自己百度，然后创建自己人脸库，获取到对应的appKey,appSecret
百度开发文档
/docs#/Face-Java-SDK/top
三、代码实现
基于Springboot框架搭建的，前端使用Vue,通过摄像机拍下照片后，请求后端人脸识别登陆服务，后台调用百度API人脸识别接口，进入百度大脑搜索人脸识别即可获取官网的Secret Key，将前端获取的人脸信息的base64信息和你本地数据库里的人脸信息传到百度人脸识别的接口进行人脸比对，返回一个json数据，result参数 带别人脸相似度, result可自己定义，从而实现人脸识别登录。
核心代码
3.1引入Maven依赖
<!-- 人脸识别 jdk--><dependency><groupId>com.baidu.aip</groupId><artifactId>java-sdk</artifactId><version>4.9.0</version><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-simple</artifactId></exclusion></exclusions></dependency>
3.2 创建FaceUtil，获取ApiFace【单例】
package mon.face.utils;import com.baidu.aip.face.AipFace;import com.baidu.aip.util.Base64Util;/*** User: lanxinghua* Date: /8/30 11:04* Desc: 人脸识别工具*/public class FaceUtil {private static final String APP_ID = "15303677";private static final String APP_KEY = "OoOqVhksc3k6ZRNId8Apjd";private static final String SECRET_KEY = "unjW6yGDd2B50KulCWfNAgwA75wLI";private static volatile AipFace client = new AipFace(APP_ID, APP_KEY, SECRET_KEY);// 创建单例避免多次获取sdkpublic static AipFace getClient(){client.setConnectionTimeoutInMillis(2000);client.setSocketTimeoutInMillis(60000);return client;}/*** 编码* @param form* @return*/public static String encodeBase64(byte[] form){return Base64Util.encode(form);}/*** 解码* @param data* @return*/public static byte[] decodeBase64(String data){return Base64Util.decode(data);}}
3.3 创建FaceResultUtil，统一处理请求
package mon.face.utils;import com.alibaba.fastjson.JSON;import mon.exception.BizException;import mon.face.constant.ErrorEnum;import mon.face.constant.FaceConstant;import mon.face.dto.FaceResult;import org.json.JSONObject;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/*** User: lanxinghua* Date: /8/30 13:52* Desc: 结果工具封装*/public class FaceResultUtil {private static final Logger logger = LoggerFactory.getLogger("百度API接口请求结果解析");public static FaceResult isSuccess(JSONObject res){FaceResult result = parseJsonObject(res);if (!result.isSuccess()){// 对错误进行分类ErrorEnum errorEnum = ErrorEnum.getInstance(result.getErrorCode());if (errorEnum == null){throw new BizException("百度接口请求失败" + result.getErrorMsg());}else {throw new BizException(errorEnum.getCnDesc());}}return result;}/*** 解析JsonObject* @return*/private static FaceResult parseJsonObject(JSONObject res){FaceResult faceResult = FaceResult.builder().build();try {String logId = res.has(FaceConstant.LOG_ID) ? res.get(FaceConstant.LOG_ID).toString() : "0";int errorCode = res.has(FaceConstant.ERROR_CODE) ? res.getInt(FaceConstant.ERROR_CODE) : -1;String errorMsg = res.has(FaceConstant.ERROR_MSG) ? res.getString(FaceConstant.ERROR_MSG) : "";int cached = res.has(FaceConstant.CACHED) ? res.getInt(FaceConstant.CACHED) : 0;long timestamp = res.has(FaceConstant.TIMESTAMP) ? res.getLong(FaceConstant.TIMESTAMP) : 0;Object dataString = res.has(FaceConstant.RESULT) ? res.get(FaceConstant.RESULT) : "";com.alibaba.fastjson.JSONObject data = null;if (dataString != null) {data = com.alibaba.fastjson.JSONObject.parseObject(dataString.toString());}faceResult.setLogId(logId);faceResult.setErrorCode(errorCode);faceResult.setErrorMsg(errorMsg);faceResult.setCached(cached);faceResult.setTimestamp(timestamp);faceResult.setData(data);}catch (Exception e){logger.error("JSONObject解析失败", e);}return faceResult;}}
3.4 创建FaceResult
package mon.face.dto;import com.alibaba.fastjson.JSONObject;import lombok.AllArgsConstructor;import lombok.Builder;import lombok.Data;import lombok.NoArgsConstructor;import java.io.Serializable;/*** User: lanxinghua* Date: /8/30 13:57* Desc: 请求百度API接口结果*/@Data@Builder@AllArgsConstructor@NoArgsConstructorpublic class FaceResult implements Serializable {private String logId;private String errorMsg;private int cached;private int errorCode;private long timestamp;private JSONObject data;public boolean isSuccess(){return 0 == this.errorCode ? true : false;}}
3.5 创建ImageU
package mon.face.dto;import mon.face.constant.ImageTypeEnum;import lombok.AllArgsConstructor;import lombok.Builder;import lombok.Data;import lombok.NoArgsConstructor;import java.io.Serializable;/*** User: lanxinghua* Date: /8/30 11:25* Desc: 图像对象*/@Data@Builder@AllArgsConstructor@NoArgsConstructorpublic class ImageU implements Serializable {private ImageTypeEnum imageTypeEnum;private String data;}
3.6 创建FaceUserDTO
package mon.face.dto;import mon.face.constant.FaceConstant;import lombok.AllArgsConstructor;import lombok.Builder;import lombok.Data;import lombok.NoArgsConstructor;import java.io.Serializable;/*** User: lanxinghua* Date: /8/30 12:12* Desc:*/@Data@Builder@AllArgsConstructor@NoArgsConstructorpublic class FaceUserDTO<T> implements Serializable {private String userId;private String groupId = FaceConstant.DEFAULT_GROUP_ID;private String faceToken;private T user;}
3.7 创建FaceManage[关键类]
package mon.face;import com.alibaba.fastjson.JSON;import com.baidu.aip.face.FaceVerifyRequest;import com.baidu.aip.face.MatchRequest;import mon.face.constant.ActionTypeEnum;import mon.face.constant.FaceConstant;import mon.face.constant.LivenessControlEnum;import mon.face.constant.QualityControlEnum;import mon.face.dto.FaceResult;import mon.face.dto.FaceUserDTO;import
