选择人工智能-->人脸识别认证

选择-->立即使用

选择免费尝鲜（领取之后五分钟就可以在我的应用里查看了，里面勾选所有的选项）

在我的应用里查看公共云（记住AppID、APIKey、SelectKey，程序中需要）

在IDEA中运行程序

先导入需要的依赖

<dependencies><dependency><groupId>com.baidu.aip</groupId><artifactId>java-sdk</artifactId><version>4.4.0</version></dependency></dependencies>

再运行下面这个程序

import com.baidu.aip.face.AipFace;
import com.baidu.aip.face.MatchRequest;
import org.json.JSONObject;import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Base64;public class Sample {public int faceCompare(AipFace client,String imagePath1,String imagePath2) {// 将图片文件转换为base64编码的字符串String image1 = encodeImageToBase64(imagePath1);String image2 = encodeImageToBase64(imagePath2);// image1/image2也可以为url或facetoken, 相应的imageType参数需要与之对应。MatchRequest req1 = new MatchRequest(image1, "BASE64");MatchRequest req2 = new MatchRequest(image2, "BASE64");ArrayList<MatchRequest> requests = new ArrayList<MatchRequest>();requests.add(req1);requests.add(req2);JSONObject res = client.match(requests);System.out.println(res.toString(2));return res.getInt("score");}private String encodeImageToBase64(String imagePath) {try (FileInputStream imageInFile = new FileInputStream(imagePath)) {// 读取图片字节数据byte[] bytes = new byte[(int) new File(imagePath).length()];imageInFile.read(bytes);// 转换为base64编码的字符串return Base64.getEncoder().encodeToString(bytes);} catch (IOException e) {e.printStackTrace();return null;}}public static void main(String[] args) {Sample sample = new Sample();AipFace client = new AipFace("Enter Your APP_ID", "Enter Your API_KEY", "Enter Your SECRET_KEY");//输入之前保存的三个参数String imagePath1 = "path/to/image1";//输入你要比对的照片String imagePath2 = "path/to/image2";//输入你要比对的第二张照片int score = sample.faceCompare(client, imagePath1, imagePath2);System.out.println("Score: " + score);// 输出比对的相似度结果}
}
