這個是人臉識別時沒法檢測到圖片報的錯，有時候咱們檢測一張圖片是否在庫裏面，當一張圖片明顯在裏面，還檢測不到，以下面是個人代碼

 1 package Test1;
 2 
 3 import java.io.IOException;
 4 import java.util.Arrays;
 5 import java.util.HashMap;
 6 
 7 import org.json.JSONObject;
 8 
 9 import com.baidu.aip.face.AipFace;
10 
11 /**
12  * 人臉對比
13  */
14 public class BaiduFaceTest {
15 
16 // 這裏填寫你本身應用的三項
17     public static final String APP_ID = "16090420";
18     public static final String API_KEY = "iinpWTE1pvOnH3YNmk4tG5Z6";
19     public static final String SECRET_KEY = "LMl3pgidH2AzGcTnOM3qh1x3GFnh6jt5";
20 
21 
22 
23     public static void main(String[] args) throws IOException {
24         AipFace client = new AipFace(APP_ID, API_KEY, SECRET_KEY);
25 
26         String image1 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\a.jpg";
27         String image2 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\b.jpg";
28 
29 
30           JSONObject rs = client.search(image1, "BASE64", "group002", new HashMap<>());
31        // JSONObject rs=client.detect(image1, "URL", new HashMap<>());
32         System.out.println(rs.toString(2));
33 
34     }
35 
36 }

最後才搞明白是由於咱們必須把圖片轉爲BASE64才能正確的和庫裏面的圖片比對，下面引入了加密函數

 1 package Test1;
 2 
 3 import java.io.FileInputStream;
 4 import java.io.IOException;
 5 import java.io.InputStream;
 6 import java.util.HashMap;
 7 
 8 import org.json.JSONObject;
 9 
10 import com.baidu.aip.face.AipFace;
11 
12 import sun.misc.BASE64Encoder;
13 
14 /**
15  * 人臉對比
16  */
17 public class BaiduFaceTest {
18 
19 // 這裏填寫你本身應用的三項
20     public static final String APP_ID = "16090420";
21     public static final String API_KEY = "iinpWTE1pvOnH3YNmk4tG5Z6";
22     public static final String SECRET_KEY = "LMl3pgidH2AzGcTnOM3qh1x3GFnh6jt5";
23 
24 
25 
26     public static void main(String[] args) throws IOException {
27         AipFace client = new AipFace(APP_ID, API_KEY, SECRET_KEY);
28 
29         String image1 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\c.jpg";
30         System.out.println(image1);
31         String image2 = "C:\\Users\\19575\\Pictures\\Saved Pictures\\紫霞仙子\\b.jpg";
32        
33         String msg=GetImageStr(image1);
34           JSONObject rs = client.search(msg, "BASE64", "group002", new HashMap<>());
35        // JSONObject rs=client.detect(image1, "URL", new HashMap<>());
36         System.out.println(rs.toString(2));
37 
38     }
39     public static String GetImageStr(String imgFile)  
40     {//將圖片文件轉化爲字節數組字符串，並對其進行Base64編碼處理  
41         InputStream in = null;  
42         byte[] data = null;  
43         //讀取圖片字節數組  
44         try   
45         {  
46             in = new FileInputStream(imgFile);          
47             data = new byte[in.available()];  
48             in.read(data);  
49             in.close();  
50         }   
51         catch (IOException e)   
52         {  
53             e.printStackTrace();  
54         }  
55         //對字節數組Base64編碼  
56         BASE64Encoder encoder = new BASE64Encoder();  
57         return encoder.encode(data);//返回Base64編碼過的字節數組字符串  
58     }  
59 
60 
61 }

不過加密解密函數沒法直接使用，須要經過下面這個教程把自帶的jar包導進去

這樣能夠正確的檢測到圖片了。
