基于百度AI的人像识别开发的登录模块

### 首先这是一个java的SSM框架的项目，没学过java或没接触过SSM的可能不太适合。数据库用的是mysql ###

整体思路：使用HTML5的video和canvas来截取摄像头拍摄视频的图片base64数据，将拍摄的base64格式数据和之前在数据库中存好的人像数据上传到百度AI的处理中心，进行人像识别分析，并将结果回传，结果数据是json格式的，需要进行有效数据的提取，如果相似度达到90%,就判定为本人，登录验证通过。

数据库设计思路：数据表的结构很简单，一共有三个字段，id、data、username。但是有个问题，base64是非常长的一串数据，想想几万、几十万字符的数据直接存入数据库，是非常不明智的选择，当数据量稍微一多，会严重拖垮数据库的性能。所以正确操作可以将数据转成图片存到本地，数据库中只保存地址。但我作为演示操作，数据量小，就做了个错误的示范，我用longblob类型来保存的base64数据。

下面步入正题：

### **1.注册[百度AI][AI]，进入控制台后，点击左侧导航菜单，进入人脸识别模块。**![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzMzNjA5NDAx_size_16_color_FFFFFF_t_70][] ###

### **2.点击创建应用，然后添加你所要创建应用的一些信息，创建成功后会进入下图的界面** ###

###  **3.记住你的API key和Secret key，后面会用到。** ###

### **4.下面开始写代码，首先创建Particleground.jsp，这是用来人像登录的页面，代码如下：** ###

### **上面JSP页面所依赖的css和js，我会上传到CSDN的资源下载中，在本文的最后会附上链接，我看看能不能设置成免费，尽量分低一点。** ###

### **5.刚才让记住的两个KEY是为了获取token的，下面是获取token的一个工具类：** ###

package com.hanpeng.utils;
    
    import net.sf.json.JSONObject;
    
    import java.io.BufferedReader;
    import java.io.InputStreamReader;
    import java.net.HttpURLConnection;
    import java.net.URL;
    
    public class GetToken {
    
       public static String getToken() {
          BufferedReader br = null;
          StringBuffer sb = new StringBuffer();
    
          String authHost = "https://aip.baidubce.com/oauth/2.0/token?";
    
          String clientId = "PfaxdmuNuNyGhTcbtD2vkcuf";
          String clientSecret = "dV7hZSmDWoNIIuBUNbtzC0XKmVy0v3tw";
          String getAccessTokenUrl = authHost
                + "grant_type=client_credentials"
                + "&client_id=" + clientId
                + "&client_secret=" + clientSecret;
          try {
             URL url = new URL(getAccessTokenUrl);
             HttpURLConnection connection = (HttpURLConnection) url
                   .openConnection();
             connection.setRequestMethod("POST");
             connection.connect();
             br = new BufferedReader(new InputStreamReader(
                   connection.getInputStream()));
             String line = "";
             while ((line = br.readLine()) != null) {
                sb.append(line);
             }
             br.close();
          } catch (Exception e) {
             e.printStackTrace();
          }
          JSONObject jsonObject = JSONObject.fromObject(sb.toString());
          String token = jsonObject.getString("access_token");
          return token;
       }
    }

### **6.下面是LoginController层** ###

//百度人脸识别登录验证
    @RequestMapping("faceRecognition")
    void faceRecognition(HttpServletRequest request, HttpServletResponse response, String baseData) throws IOException {
        System.out.println(baseData);
        PrintWriter writer = response.getWriter();
        HttpSession session = request.getSession();
        boolean flag = false;
        List<FaceRecognition> list = service.getBaseList();
        for (FaceRecognition faceRecognition : list) {
            String image2 = faceRecognition.getFace_base64();
            if (service.getResult(baseData, image2)) {
                flag = true;
                session.setAttribute("username", faceRecognition.getUsername());
                break;
            }
        }
        writer.print(flag);
        writer.close();
    }
    
    //百度人脸信息录入(返回的状态码：0：用户人脸数据存储已达上限，1：人脸信息录入成功， 2：人脸信息录入失败（照片不合格）)
    @RequestMapping("faceEntry")
    public void faceEntry(HttpServletRequest request, HttpServletResponse response, String faceData) throws IOException {
        HttpSession session = request.getSession();
        String username = (String) session.getAttribute("username");
        PrintWriter writer = response.getWriter();
        //检测该用户下的人脸信息数据是否超过5条
        if (service.queryCountByFaceInfo(username,5)) {
            //进行人脸信息录入
            if (service.getFaceResult(faceData)) {
                writer.write("{\"flag\":\"1\"}");
                FaceRecognition faceRecognition = new FaceRecognition(username, faceData);
                service.insertFaceInfo(faceRecognition);
            }else{
                writer.write("{\"flag\":\"2\"}");
            }
        }else {
            writer.write("{\"flag\":\"0\"}");
        }
        writer.close();
    }

### **7.下面是LoginService接口类** ###

public interface LoginService {
    
        public List<Admin> Login(String username, String password);
    
        public List<FaceRecognition> getBaseList();
    
        public boolean getResult(String image1, String image2) throws IOException;
    
        public boolean getFaceResult(String image) throws IOException;
    
        public void insertFaceInfo(FaceRecognition faceRecognition);
    
        public boolean queryCountByFaceInfo(String username, int n);
    
        public List<Map<String, ?>> userInfo(String userName);
    
        public void upDate(String date, String userName);
    
        public void modifyPassWord(String userName, String passWord);
    }

### **8.下面是LoginService类的实现类LoginServiceImpl类，我只挑了和人脸识别相关的方法：** ###

//人脸识别检测
    @Override
    public boolean getResult(String image1, String image2) throws IOException {
        boolean flag = false;

            Map<String, Object> map1 = new HashMap<>();
            map1.put("image", image1);
            map1.put("image_type", "BASE64");
            map1.put("face_type", "LIVE");
            map1.put("quality_control", "LOW");
            map1.put("liveness_control", "NORMAL");
    
            Map<String, Object> map2 = new HashMap<>();
            map2.put("image", image2);
            map2.put("image_type", "BASE64");
            map2.put("face_type", "LIVE");
            map2.put("quality_control", "LOW");
            map2.put("liveness_control", "NORMAL");
    
            images.add(map1);
            images.add(map2);
    
            String param = GsonUtils.toJson(images);
    
            // 注意这里仅为了简化编码每一次请求都去获取access_token，线上环境access_token有过期时间， 客户端可自行缓存，过期后重新获取。
            String accessToken = GetToken.getToken();
    
            String result = HttpUtil.post(url, accessToken, "application/json", param);
            System.out.println(result);
    
            //用json提取result中的有效数据
            JSONObject myJson = new JSONObject(result);
            int error = myJson.getInt("error_code");
            if (error == 0) {
                JSONObject resultList = (JSONObject) myJson.get("result");
                double score = resultList.getDouble("score");
                System.out.println(score);
                if (score >= 90) {
                    flag = true;
                }
            }
                return flag;
            } catch(Exception e){
                e.printStackTrace();
            }
        return flag;
    }
    
    //人脸信息录入
    @Override
    public boolean getFaceResult(String image) throws IOException {

### **注意，上述代码引入了几个帮助类：Base64Util、FileUtil、GsonUtils、HttpUtil。这几个类都会在我上传到CSDN的资源下载中，在本文的最后会附上链接，我看看能不能设置成免费，尽量分低一点。** ###

### **9.下面是LoginDao：** ###

public interface LoginDao {
       List<Admin> queryByNameAndPassword(@Param("username") String username, @Param("password") String password);
    
       List<FaceRecognition> getBaseList();
    
       void insertFaceInfo(FaceRecognition faceRecognition);
    
       int queryCountByFaceInfo(@Param("username") String username);
    
       List<Map<String, ?>> queryUserInfo(@Param("userName") String userName);
    
       void upDate(@Param("date") String date, @Param("userName") String userName);
    
       void modifyPassWord(@Param("userName") String userName, @Param("passWord") String passWord);
    
    }

### **10.下面是mapping文件，loginDao.xml** ###

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "mybatis-3-mapper.dtd" >
    <mapper namespace="com.hanpeng.dao.LoginDao">
       
       
       <select id="queryByNameAndPassword" parameterType="String" resultType="com.hanpeng.bean.Admin">
          select * from admin where admin_username=#{username} and admin_password=#{password}
       </select>
       
       <select id="getBaseList" resultType="com.hanpeng.bean.FaceRecognition">
          select * from face_Recognition
       </select>
       
       <insert id="insertFaceInfo" parameterType="com.hanpeng.bean.FaceRecognition">
          insert into face_Recognition(face_base64,username) values(#{face_base64},#{username})
       </insert>
       
       <select id="queryCountByFaceInfo" parameterType="String" resultType="int">
          select count(*) from face_Recognition where username=#{username}
       </select>
       
       <select id="queryUserInfo" parameterType="String" resultType="Map">
          select * from user where username=#{userName}
       </select>
       
       <update id="upDate" parameterType="String">
       update user set date=#{date} where username=#{userName}
       </update>
       
       <update id="modifyPassWord" parameterType="String">
       update user set password=#{passWord} where username=#{userName}
       </update>
    </mapper>
