{ "result": null, "log_id": 304592860300941982, "error_msg": "image check fail", "cached": 0, "error_code": 222203, "timestamp": 1556030094 }

这个是人脸识别时无法检测到图片报的错，有时候我们检测一张图片是否在库里面，当一张图片明显在里面，还检测不到，如下面是我的代码

package Test1;

import java.io.IOException;
import java.util.Arrays;
import java.util.HashMap;

import org.json.JSONObject;

import com.baidu.aip.face.AipFace;

/**
 * 人脸对比
 */
public class BaiduFaceTest {

// 这里填写你自己应用的三项
    public static final String APP_ID = "16090420";
    public static final String API_KEY = "iinpWTE1pvOnH3YNmk4tG5Z6";
    public static final String SECRET_KEY = "LMl3pgidH2AzGcTnOM3qh1x3GFnh6jt5";



    public static void main(String[] args) throws IOException {
        AipFace client = new AipFace(APP_ID, API_KEY, SECRET_KEY);

        String image1 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\a.jpg";
        String image2 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\b.jpg";


          JSONObject rs = client.search(image1, "BASE64", "group002", new HashMap<>());
       // JSONObject rs=client.detect(image1, "URL", new HashMap<>());
        System.out.println(rs.toString(2));

    }

}

最后才搞明白是因为我们必须把图片转为BASE64才能正确的和库里面的图片比对，下面引入了加密函数

package Test1;

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;

import org.json.JSONObject;

import com.baidu.aip.face.AipFace;

import sun.misc.BASE64Encoder;

/**
 * 人脸对比
 */
public class BaiduFaceTest {

// 这里填写你自己应用的三项
    public static final String APP_ID = "16090420";
    public static final String API_KEY = "iinpWTE1pvOnH3YNmk4tG5Z6";
    public static final String SECRET_KEY = "LMl3pgidH2AzGcTnOM3qh1x3GFnh6jt5";



    public static void main(String[] args) throws IOException {
        AipFace client = new AipFace(APP_ID, API_KEY, SECRET_KEY);

        String image1 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\c.jpg";
        System.out.println(image1);
        String image2 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\b.jpg";
       
        String msg=GetImageStr(image1);
          JSONObject rs = client.search(msg, "BASE64", "group002", new HashMap<>());
       // JSONObject rs=client.detect(image1, "URL", new HashMap<>());
        System.out.println(rs.toString(2));

    }
    public static String GetImageStr(String imgFile)  
    {//将图片文件转化为字节数组字符串，并对其进行Base64编码处理  
        InputStream in = null;  
        byte[] data = null;  
        //读取图片字节数组  
        try   
        {  
            in = new FileInputStream(imgFile);          
            data = new byte[in.available()];  
            in.read(data);  
            in.close();  
        }   
        catch (IOException e)   
        {  
            e.printStackTrace();  
        }  
        //对字节数组Base64编码  
        BASE64Encoder encoder = new BASE64Encoder();  
        return encoder.encode(data);//返回Base64编码过的字节数组字符串  
    }  


}

不过加密解密函数无法直接使用，需要通过下面这个教程把自带的jar包导进去

这样可以正确的检测到图片了。
