第一步：鉴权服务技术方案

Java代码实现如下

1. import java.util.Date;  
2.   
3. import com.baidu.aip.util.Base64Util;  
4. /** 
5.  * 获取Authorization 
6.  * @author 小帅丶 
7.  * @类名称  Sign 
8.  * @remark  
9.  * @date  2017-8-18 
10.  */  
11. public class Sign {  
12.     /** 
13.      * Authorization方法 
14.      * @param userQQ 开发者创建应用时的QQ号 
15.      * @param AppID 开发者创建应用后的AppID 
16.      * @param SecretID 开发者创建应用后的SecretID 
17.      * @param SecretKey 开发者创建应用后的SecretKey 
18.      * @return sign 
19.      * @throws Exception 
20.      */  
21.     public static String getSign(String userQQ,String AppID,String SecretID,String SecretKey) throws Exception{  
22.         long tnowTimes = new Date().getTime()/1000;  
23.         long enowTimes = tnowTimes+2592000;  
24.         String rRandomNum = HMACSHA1.genRandomNum(10);  
25.         String param = "u=" + userQQ + "&a=" + AppID + "&k=" + SecretID + "&e="  
26.                 + enowTimes + "&t=" + tnowTimes + "&r=" + rRandomNum + "&f=";  
27.         byte [] hmacSign = HMACSHA1.getSignature(param, SecretKey);  
28.         byte[] all = new byte[hmacSign.length+param.getBytes().length];  
29.         System.arraycopy(hmacSign, 0, all, 0, hmacSign.length);  
30.         System.arraycopy(param.getBytes(), 0, all, hmacSign.length, param.getBytes().length);  
31.         String sign = Base64Util.encode(all);  
32.         return sign;  
33.     }  
34. }  

需要的HMACSHA1代码及随机数代码

1. import java.util.Random;  
2.   
3. import javax.crypto.Mac;  
4. import javax.crypto.spec.SecretKeySpec;  
5.   
6. /** 
7.  * HMACSHA1算法 
8.  *  
9.  * @author 小帅丶 
10.  * @类名称 HMACSHA1 
11.  * @remark 
12.  * @date 2017-8-18 
13.  */  
14. public class HMACSHA1 {  
15.     /** 
16.      * 算法标识 
17.      */  
18.     private static final String HMAC_SHA1 = "HmacSHA1";  
19.     /**

21.      * @param data 要加密的数据 
22.      * @param key 密钥  
23.      * @return 
24.      * @throws Exception 
25.      */  
26.     public static byte[] getSignature(String data, String key) throws Exception {  
27.         Mac mac = Mac.getInstance(HMAC_SHA1);  
28.         SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(),  
29.                 mac.getAlgorithm());  
30.         mac.init(signingKey);  
31.         return mac.doFinal(data.getBytes());  
32.     }  
33.     /** 
34.      * 生成随机数字 
35.      * @param length 
36.      * @return 
37.      */  
38.     public static String genRandomNum(int length){    
39.         int  maxNum = 62;    
40.         int i;    
41.         int count = 0;    
42.         char[] str = {‘0‘, ‘1‘, ‘2‘, ‘3‘, ‘4‘, ‘5‘, ‘6‘, ‘7‘, ‘8‘, ‘9‘};        
43.         StringBuffer pwd = new StringBuffer("");    
44.         Random r = new Random();    
45.         while(count < length){    
46.          i = Math.abs(r.nextInt(maxNum));       
47.          if (i >= 0 && i < str.length) {    
48.           pwd.append(str[i]);    
49.           count ++;    
50.          }    
51.         }    
52.         return pwd.toString();    
53.       }   
54. }  

第二步:准备相关代码 

保存SIGN 或者每次都生成一个也可以 方便测试就直接每次生成一个了

开始识别图片之前需要工具类Base64Util  FileUtil

FileUtil代码 

1. import java.io.*;  
2.   
3. /** 
4.  * 文件读取工具类 
5.  */  
6. public class FileUtil {  
7.   
8.     /** 
9.      * 读取文件内容，作为字符串返回 
10.      */  
11.     public static String readFileAsString(String filePath) throws IOException {  
12.         File file = new File(filePath);  
13.         if (!file.exists()) {  
14.             throw new FileNotFoundException(filePath);  
15.         }   
16.   
17.         if (file.length() > 1024 * 1024 * 1024) {  
18.             throw new IOException("File is too large");  
19.         }   
20.   
21.         StringBuilder sb = new StringBuilder((int) (file.length()));  
22.         // 创建字节输入流    
23.         FileInputStream fis = new FileInputStream(filePath);    
24.         // 创建一个长度为10240的Buffer  
25.         byte[] bbuf = new byte[10240];    
26.         // 用于保存实际读取的字节数    
27.         int hasRead = 0;    
28.         while ( (hasRead = fis.read(bbuf)) > 0 ) {    
29.             sb.append(new String(bbuf, 0, hasRead));    
30.         }    
31.         fis.close();    
32.         return sb.toString();  
33.     }  
34.   
35.     /** 
36.      * 根据文件路径读取byte[] 数组 
37.      */  
38.     public static byte[] readFileByBytes(String filePath) throws IOException {  
39.         File file = new File(filePath);  
40.         if (!file.exists()) {  
41.             throw new FileNotFoundException(filePath);  
42.         } else {  
43.             ByteArrayOutputStream bos = new ByteArrayOutputStream((int) file.length());  
44.             BufferedInputStream in = null;  
45.   
46.             try {  
47.                 in = new BufferedInputStream(new FileInputStream(file));  
48.                 short bufSize = 1024;  
49.                 byte[] buffer = new byte[bufSize];  
50.                 int len1;  
51.                 while (-1 != (len1 = in.read(buffer, 0, bufSize))) {  
52.                     bos.write(buffer, 0, len1);  
53.                 }  
54.   
55.                 byte[] var7 = bos.toByteArray();  
56.                 return var7;  
57.             } finally {  
58.                 try {  
59.                     if (in != null) {  
60.                         in.close();  
61.                     }  
62.                 } catch (IOException var14) {  
63.                     var14.printStackTrace();  
64.                 }  
65.   
66.                 bos.close();  
67.             }  
68.         }  
69.     }  
70. }  

Base64Util  代码

创建应用得到的值放在一个常量类里面

17.      */  
18.     public static String getDetectFace(String imagePath) throws Exception{  
19.         //得到Authorization  
20.         String sign = Sign.getSign(YouTuAppContants.userQQ,  
21.                 YouTuAppContants.AppID, YouTuAppContants.SecretID,  
22.                 YouTuAppContants.SecretKey);  
23.         byte[] imgData = FileUtil.readFileByBytes(imagePath);  
24.         String image =  Base64Util.encode(imgData);;  
25.         String param = "{\"app_id\":\""+YouTuAppContants.AppID+"\",\"image\":\""+image+"\"}";  
26.         String result = HttpUtilYoutu.post(DETECTFACE_URL, param, "UTF-8",sign);
