自定义人脸检索_人脸图片检索_内容安全_调用示例_Java SDK

前提条件

在使用本教程之前，请确保已完成以下操作：

使用Alibaba Cloud SDK for Java，您需要一个阿里云账号和访问密钥（AccessKey）。请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。

确保您已经安装了Alibaba Cloud SDK for Java，准确的SDK版本号，请参见阿里云开发工具包（SDK）。

    "msg":"OK",
    "code":200,
    "data":[
        {
            "msg":"OK",
