本文档将利用京东云AI SDK来实践人脸识别中的人脸搜索功能，主要涉及到分组创建/删除、分组列表获取、人脸创建/删除、人脸搜索，本次实操的最终效果是： 创建一个人脸库，拿一张图片在人脸库中搜索出相似度最高的一张，实现1：N的人脸识别，操作示意图如下：
人脸搜索通过 API 调用次数计费，目前人脸搜索功能有 0元免费试用，调用量限制为 13
右击JAVA项目中的 src目录，依次点击 new- Package
接下来我们分别创建分组创建（ faceGroupCreate）/删除（ faceGroupDelete）、分组列表获取（ getFaceGroupList）、人脸创建（ faceCreate）/删除（ faceDelete）、人脸搜索（ faceSearch）相关的 （类）Class，新建 Class的方法如下：
全部Class创建完成后如下图：
刷新Eclipse中的 Package Explorer便可看到我们复制进来的京东云AI SDK文件，选中全部jar包文件，右击，依次点击 Build Path- Add to Build Path来重新构建路径（Build Path）
重新构建路径完成后，我们在Eclipse的 Package Explorer中可看到 Referenced Libraries，里面包含我们重构路径的所有jar包

12//创建分组

14 public static void main(String[] args) {
15 String accessKey = "请输入您的AK";
16 String secretKey = "请输入您的SK";
17 String endPoint = "aiapi.jdcloud.com";

28 endPoint, path, method, headers, queryMap, body);
29 System.out.println(new String(BinaryUtils.toByteArray(response.getContent())));
30 } catch (IOException e) {
31 System.out.println(e.getMessage());
32 }
33 }
34}
右击代码依次点击 Run as- 1 Java Application运行代码
运行后发现报错信息如下（ 这里虽然有报错，但我们定义的名称为 请输入分组名称 的组已成功创建）：
由此我们可以看出，报出错误的地方主要是slf4j的jar包，而故障码中 Failed to load class "org.slf4j.impl.StaticLoggerBinder"的意思则是 加载类文件org.slf4j.impl.StaticLoggerBinder时失败
接下来依次创建其他类文件
注意：如下代码中涉及到 String body = "imageBase64=";的部分 需要先将图片转换为Base64，转换地址为：http://imgbase64.duoshitong.com/； 然后将转换后的代码复制到 imageBase64=之后（转换后的代码需去除掉“ data:image/jpeg;base64,”后再复制）。

如下演示都通过右击对应的代码执行 Run as- 1 Java Application来运行代码查看结果
如上，我们通过 marin1.jpg、 marin2.jpg、 corona.jpg、 dog.jpg创建了人脸库，最后通过 marin.jpg将相似度最高的 marin1.jpg搜索了出来，至此，操作演示完毕~~
