第一步：鑒權服務技術方案

Java代碼實現如下

1. import java.util.Date;
3. import com.baidu.aip.util.Base64Util;
4. /**
5. * 獲取Authorization
6. * @author 小帥丶
7. * @類名稱 Sign

15. * @param AppID 開發者創建應用後的AppID
16. * @param SecretID 開發者創建應用後的SecretID
17. * @param SecretKey 開發者創建應用後的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代碼及隨機數代碼

1. import java.util.Random;
3. import javax.crypto.Mac;
4. import javax.crypto.spec.SecretKeySpec;
6. /**
7. * HMACSHA1算法
8. *
9. * @author 小帥丶
10. * @類名稱 HMACSHA1
11. * @remark
12. * @date 2017-8-18
13. */
14. public class HMACSHA1 {
15. /**
16. * 算法標識
17. */
18. private static final String HMAC_SHA1 = "HmacSHA1";
19. /**
20. * 加密
21. * @param data 要加密的數據
22. * @param key 密鑰
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. * 生成隨機數字
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:準備相關代碼

保存SIGN 或者每次都生成一個也可以 方便測試就直接每次生成一個了

開始識別圖片之前需要工具類Base64Util FileUtil

FileUtil代碼

1. import java.io.*;
3. /**
4. * 文件讀取工具類
5. */
6. public class FileUtil {
8. /**
9. * 讀取文件內容，作為字符串返回
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. }
17. if (file.length() > 1024 * 1024 * 1024) {
18. throw new IOException("File is too large");
19. }
21. StringBuilder sb = new StringBuilder((int) (file.length()));
22. // 創建字節輸入流
23. FileInputStream fis = new FileInputStream(filePath);
24. // 創建一個長度為10240的Buffer
25. byte[] bbuf = new byte[10240];
26. // 用於保存實際讀取的字節數
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. }
35. /**
36. * 根據文件路徑讀取byte[] 數組
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;
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. }
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. }
66. bos.close();
67. }
68. }
69. }
70. }

Base64Util 代碼

1. /**
2. * Base64 工具類
3. */
4. public class Base64Util {
5. private static final char last2byte = (char) Integer.parseInt("00000011", 2);
6. private static final char last4byte = (char) Integer.parseInt("00001111", 2);
7. private static final char last6byte = (char) Integer.parseInt("00111111", 2);
8. private static final char lead6byte = (char) Integer.parseInt("11111100", 2);
9. private static final char lead4byte = (char) Integer.parseInt("11110000", 2);
10. private static final char lead2byte = (char) Integer.parseInt("11000000", 2);
11. private static final char[] encodeTable = new char[]{‘A‘, ‘B‘, ‘C‘, ‘D‘, ‘E‘, ‘F‘, ‘G‘, ‘H‘, ‘I‘, ‘J‘, ‘K‘, ‘L‘, ‘M‘, ‘N‘, ‘O‘, ‘P‘, ‘Q‘, ‘R‘, ‘S‘, ‘T‘, ‘U‘, ‘V‘, ‘W‘, ‘X‘, ‘Y‘, ‘Z‘, ‘a‘, ‘b‘, ‘c‘, ‘d‘, ‘e‘, ‘f‘, ‘g‘, ‘h‘, ‘i‘, ‘j‘, ‘k‘, ‘l‘, ‘m‘, ‘n‘, ‘o‘, ‘p‘, ‘q‘, ‘r‘, ‘s‘, ‘t‘, ‘u‘, ‘v‘, ‘w‘, ‘x‘, ‘y‘, ‘z‘, ‘0‘, ‘1‘, ‘2‘, ‘3‘, ‘4‘, ‘5‘, ‘6‘, ‘7‘, ‘8‘, ‘9‘, ‘+‘, ‘/‘};
13. public Base64Util() {
14. }
16. public static String encode(byte[] from) {
17. StringBuilder to = new StringBuilder((int) ((double) from.length * 1.34D) + 3);
18. int num = 0;
19. char currentByte = 0;
21. int i;
22. for (i = 0; i < from.length; ++i) {
23. for (num %= 8; num < 8; num += 6) {
24. switch (num) {
25. case 0:
26. currentByte = (char) (from[i] & lead6byte);
27. currentByte = (char) (currentByte >>> 2);
28. case 1:
29. case 3:
30. case 5:
31. default:
32. break;
33. case 2:
34. currentByte = (char) (from[i] & last6byte);
35. break;
36. case 4:
37. currentByte = (char) (from[i] & last4byte);
38. currentByte = (char) (currentByte << 2);
39. if (i + 1 < from.length) {
40. currentByte = (char) (currentByte | (from[i + 1] & lead2byte) >>> 6);
41. }
42. break;
43. case 6:
44. currentByte = (char) (from[i] & last2byte);
45. currentByte = (char) (currentByte << 4);
46. if (i + 1 < from.length) {
47. currentByte = (char) (currentByte | (from[i + 1] & lead4byte) >>> 4);
48. }
49. }
51. to.append(encodeTable[currentByte]);
52. }
53. }
55. if (to.length() % 4 != 0) {
56. for (i = 4 - to.length() % 4; i > 0; --i) {
57. to.append("=");
58. }
59. }
61. return to.toString();
62. }
63. }

創建應用得到的值放在一個常量類裏面

1. /**
2. * 常量
3. * @author 小帥丶
4. * @類名稱 YouTuAppContants
5. * @remark
6. * @date 2017-8-18

8. public class YouTuAppContants {
9. public static String AppID = "你自己的AppID ";
10. public static String SecretID = "你自己的SecretID";
11. public static String SecretKey = "你自己的SecretKey";
12. public static String userQQ = "你自己的userQQ";
13. }

還需要一個HTTPUTIL工具類

1. import java.io.BufferedReader;

4. import java.io.InputStreamReader;
5. import java.net.HttpURLConnection;

12. import javax.net.ssl.HostnameVerifier;
13. import javax.net.ssl.SSLContext;
14. import javax.net.ssl.SSLSession;
15. import javax.net.ssl.TrustManager;

18. /**
19. * http 工具類
20. */
21. public class HttpUtilYoutu {
22. private static class TrustAnyTrustManager implements X509TrustManager {

25. throws CertificateException {
26. }
28. public void checkServerTrusted(X509Certificate[] chain, String authType)
29. throws CertificateException {
30. }
32. public X509Certificate[] getAcceptedIssuers() {
33. return new X509Certificate[] {};
34. }
35. }
37. private static class TrustAnyHostnameVerifier implements HostnameVerifier {
38. public boolean verify(String hostname, SSLSession session) {
39. return true;
40. }
41. }

57. public static String post(String url, String content,String charset,String sign)
58. throws NoSuchAlgorithmException, KeyManagementException,
59. IOException {
60. SSLContext sc = SSLContext.getInstance("SSL");
61. sc.init(null, new TrustManager[] { new TrustAnyTrustManager() },
62. new java.security.SecureRandom());
63. URL console = new URL(url);
64. Integer length = content.length();
65. HttpURLConnection conn = (HttpURLConnection) console.openConnection();
66. //文檔要求填寫的Header參數
67. conn.setRequestProperty("Host", "api.youtu.qq.com");

92. }

第三步:測試一下人臉檢測接口

請求示例類：

1. import com.xiaoshuai.test.Base64Util;
2. import com.xiaoshuai.test.FileUtil;
4. public class DetectFace {
5. //人臉檢測接口
6. public static String DETECTFACE_URL="http://api.youtu.qq.com/youtu/api/detectface";
7. public static void main(String[] args) throws Exception {
8. String imagePath = "G:/test2.jpg";
9. System.out.println(getDetectFace(imagePath));
11. }
12. /**
13. * 檢測圖中人臉信息
14. * @param imagePath 圖片路徑
15. * @return
16. * @throws Exception
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);
27. System.out.println(result);
28. return result;
29. }
30. }

看看返回的內容:
