直接234.

第一步：鉴权服务技术方案

Java代码实现如下

import java.util.Date;import com.baidu.aip.util.Base64Util;/** * 获取Authorization * @author 小帅丶 * @类名称  Sign * @remark  * @date  2017-8-18 */public class Sign {/** * Authorization方法 * @param userQQ 开发者创建应用时的QQ号 * @param AppID 开发者创建应用后的AppID * @param SecretID 开发者创建应用后的SecretID * @param SecretKey 开发者创建应用后的SecretKey * @return sign * @throws Exception */public static String getSign(String userQQ,String AppID,String SecretID,String SecretKey) throws Exception{long tnowTimes = new Date().getTime()/1000;long enowTimes = tnowTimes+2592000;String rRandomNum = HMACSHA1.genRandomNum(10);String param = "u=" + userQQ + "&a=" + AppID + "&k=" + SecretID + "&e="+ enowTimes + "&t=" + tnowTimes + "&r=" + rRandomNum + "&f=";byte [] hmacSign = HMACSHA1.getSignature(param, SecretKey);byte[] all = new byte[hmacSign.length+param.getBytes().length];System.arraycopy(hmacSign, 0, all, 0, hmacSign.length);System.arraycopy(param.getBytes(), 0, all, hmacSign.length, param.getBytes().length);String sign = Base64Util.encode(all);return sign;}}

需要的HMACSHA1代码及随机数代码

import java.util.Random;import javax.crypto.Mac;import javax.crypto.spec.SecretKeySpec;/** * HMACSHA1算法 *  * @author 小帅丶 * @类名称 HMACSHA1 * @remark * @date 2017-8-18 */public class HMACSHA1 {/** * 算法标识 */private static final String HMAC_SHA1 = "HmacSHA1";/** * 加密 * @param data 要加密的数据 * @param key 密钥  * @return * @throws Exception */public static byte[] getSignature(String data, String key) throws Exception {Mac mac = Mac.getInstance(HMAC_SHA1);SecretKeySpec signingKey = new SecretKeySpec(key.getBytes(),mac.getAlgorithm());mac.init(signingKey);return mac.doFinal(data.getBytes());}/** * 生成随机数字 * @param length * @return */public static String genRandomNum(int length){          int  maxNum = 62;          int i;          int count = 0;          char[] str = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};              StringBuffer pwd = new StringBuffer("");          Random r = new Random();          while(count < length){           i = Math.abs(r.nextInt(maxNum));              if (i >= 0 && i < str.length) {            pwd.append(str[i]);            count ++;           }          }          return pwd.toString();        } }

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

import java.io.*;/** * 文件读取工具类 */public class FileUtil {    /**     * 读取文件内容，作为字符串返回     */    public static String readFileAsString(String filePath) throws IOException {        File file = new File(filePath);        if (!file.exists()) {            throw new FileNotFoundException(filePath);        }         if (file.length() > 1024 * 1024 * 1024) {            throw new IOException("File is too large");        }         StringBuilder sb = new StringBuilder((int) (file.length()));        // 创建字节输入流          FileInputStream fis = new FileInputStream(filePath);          // 创建一个长度为10240的Buffer        byte[] bbuf = new byte[10240];          // 用于保存实际读取的字节数          int hasRead = 0;          while ( (hasRead = fis.read(bbuf)) > 0 ) {              sb.append(new String(bbuf, 0, hasRead));          }          fis.close();          return sb.toString();    }    /**     * 根据文件路径读取byte[] 数组     */    public static byte[] readFileByBytes(String filePath) throws IOException {        File file = new File(filePath);        if (!file.exists()) {            throw new FileNotFoundException(filePath);        } else {            ByteArrayOutputStream bos = new ByteArrayOutputStream((int) file.length());            BufferedInputStream in = null;            try {                in = new BufferedInputStream(new FileInputStream(file));                short bufSize = 1024;                byte[] buffer = new byte[bufSize];                int len1;                while (-1 != (len1 = in.read(buffer, 0, bufSize))) {                    bos.write(buffer, 0, len1);                }                byte[] var7 = bos.toByteArray();                return var7;            } finally {                try {                    if (in != null) {                        in.close();                    }                } catch (IOException var14) {                    var14.printStackTrace();                }                bos.close();            }        }    }}

Base64Util 代码

/** * Base64 工具类 */public class Base64Util {    private static final char last2byte = (char) Integer.parseInt("00000011", 2);    private static final char last4byte = (char) Integer.parseInt("00001111", 2);    private static final char last6byte = (char) Integer.parseInt("00111111", 2);    private static final char lead6byte = (char) Integer.parseInt("11111100", 2);    private static final char lead4byte = (char) Integer.parseInt("11110000", 2);    private static final char lead2byte = (char) Integer.parseInt("11000000", 2);    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', '+', '/'};    public Base64Util() {    }    public static String encode(byte[] from) {        StringBuilder to = new StringBuilder((int) ((double) from.length * 1.34D) + 3);        int num = 0;        char currentByte = 0;        int i;        for (i = 0; i < from.length; ++i) {            for (num %= 8; num < 8; num += 6) {                switch (num) {                    case 0:                        currentByte = (char) (from[i] & lead6byte);                        currentByte = (char) (currentByte >>> 2);                    case 1:                    case 3:                    case 5:                    default:                        break;                    case 2:                        currentByte = (char) (from[i] & last6byte);                        break;                    case 4:                        currentByte = (char) (from[i] & last4byte);                        currentByte = (char) (currentByte << 2);                        if (i + 1 < from.length) {                            currentByte = (char) (currentByte | (from[i + 1] & lead2byte) >>> 6);                        }                        break;                    case 6:                        currentByte = (char) (from[i] & last2byte);                        currentByte = (char) (currentByte << 4);                        if (i + 1 < from.length) {                            currentByte = (char) (currentByte | (from[i + 1] & lead4byte) >>> 4);                        }                }                to.append(encodeTable[currentByte]);            }        }        if (to.length() % 4 != 0) {            for (i = 4 - to.length() % 4; i > 0; --i) {                to.append("=");            }        }        return to.toString();    }}

创建应用得到的值放在一个常量类里面

/** * 常量 * @author 小帅丶 * @类名称  YouTuAppContants * @remark  * @date  2017-8-18 */public class YouTuAppContants {public static String AppID = "你自己的AppID ";public static String SecretID = "你自己的SecretID";public static String SecretKey = "你自己的SecretKey";public static String userQQ = "你自己的userQQ";}

还需要一个HTTPUTIL工具类

import java.io.BufferedReader;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;import java.security.KeyManagementException;import java.security.NoSuchAlgorithmException;import java.security.cert.CertificateException;import java.security.cert.X509Certificate; import javax.net.ssl.HostnameVerifier;import javax.net.ssl.SSLContext;import javax.net.ssl.SSLSession;import javax.net.ssl.TrustManager;import javax.net.ssl.X509TrustManager;/** * http 工具类 */public class HttpUtilYoutu { private static class TrustAnyTrustManager implements X509TrustManager {         public void checkClientTrusted(X509Certificate[] chain, String authType)                throws CertificateException {        }         public void checkServerTrusted(X509Certificate[] chain, String authType)                throws CertificateException {        }         public X509Certificate[] getAcceptedIssuers() {            return new X509Certificate[] {};        }    }     private static class TrustAnyHostnameVerifier implements HostnameVerifier {        public boolean verify(String hostname, SSLSession session) {            return true;        }    }     /**     * post方式请求服务器(https协议)     *      * @param url     *            请求地址     * @param content     *            参数     * @param charset     *            编码     * @return     * @throws NoSuchAlgorithmException     * @throws KeyManagementException     * @throws IOException     */    public static String post(String url, String content,String charset,String sign)            throws NoSuchAlgorithmException, KeyManagementException,            IOException {        SSLContext sc = SSLContext.getInstance("SSL");        sc.init(null, new TrustManager[] { new TrustAnyTrustManager() },                new java.security.SecureRandom());        URL console = new URL(url);        Integer length = content.length();        HttpURLConnection conn = (HttpURLConnection) console.openConnection();        //文档要求填写的Header参数                                conn.setRequestProperty("Host", "api.youtu.qq.com");        conn.setRequestProperty("Content-Length",length.toString());        conn.setRequestProperty("Content-Type", "text/json");        conn.setRequestProperty("Authorization", sign);                //文档要求填写的Header参数               conn.setDoOutput(true);        conn.connect();        DataOutputStream out = new DataOutputStream(conn.getOutputStream());        out.write(content.getBytes(charset));        // 刷新、关闭        out.flush();        out.close();        BufferedReader in = null;        in = new BufferedReader(                new InputStreamReader(conn.getInputStream(), charset));        String result = "";        String getLine;        while ((getLine = in.readLine()) != null) {            result += getLine;        }        in.close();        System.err.println("result:" + result);        return result;    }}

第三步:测试一下人脸检测接口

请求示例类：

import com.xiaoshuai.test.Base64Util;import com.xiaoshuai.test.FileUtil;public class DetectFace {//人脸检测接口public static String DETECTFACE_URL="http://api.youtu.qq.com/youtu/api/detectface";public static void main(String[] args) throws Exception {String imagePath = "G:/test2.jpg";System.out.println(getDetectFace(imagePath));}/** * 检测图中人脸信息 * @param imagePath 图片路径 * @return * @throws Exception */public static String getDetectFace(String imagePath) throws Exception{//得到AuthorizationString sign = Sign.getSign(YouTuAppContants.userQQ,YouTuAppContants.AppID, YouTuAppContants.SecretID,YouTuAppContants.SecretKey);byte[] imgData = FileUtil.readFileByBytes(imagePath);String image =  Base64Util.encode(imgData);;String param = "{\"app_id\":\""+YouTuAppContants.AppID+"\",\"image\":\""+image+"\"}";String result = HttpUtilYoutu.post(DETECTFACE_URL, param, "UTF-8",sign);System.out.println(result);return result;}}

看看返回的内容:

{"session_id":"","image_height":280,"image_width":359,"face":[{"face_id":"2188093443753939350","x":128,"y":127,"height":106.0,"width":106.0,"pitch":6,"roll":3,"yaw":-2,"age":23,"gender":94,"glass":true,"expression":34,"beauty":80,"face_shape":{"face_profile":[{"x":139,"y":160},{"x":139,"y":170},{"x":140,"y":180},{"x":143,"y":189},{"x":146,"y":199},{"x":150,"y":208},{"x":156,"y":217},{"x":162,"y":225},{"x":170,"y":232},{"x":179,"y":236},{"x":189,"y":238},{"x":199,"y":235},{"x":207,"y":230},{"x":214,"y":222},{"x":221,"y":214},{"x":225,"y":205},{"x":229,"y":195},{"x":231,"y":185},{"x":232,"y":174},{"x":233,"y":164},{"x":232,"y":155}],"left_eye":[{"x":152,"y":159},{"x":156,"y":161},{"x":161,"y":163},{"x":166,"y":162},{"x":171,"y":160},{"x":167,"y":157},{"x":162,"y":156},{"x":157,"y":157}],"right_eye":[{"x":216,"y":156},{"x":212,"y":159},{"x":208,"y":160},{"x":203,"y":160},{"x":198,"y":158},{"x":202,"y":155},{"x":206,"y":154},{"x":211,"y":154}],"left_eyebrow":[{"x":143,"y":148},{"x":151,"y":148},{"x":159,"y":148},{"x":166,"y":148},{"x":174,"y":147},{"x":167,"y":142},{"x":158,"y":141},{"x":150,"y":142}],"right_eyebrow":[{"x":224,"y":145},{"x":216,"y":145},{"x":208,"y":145},{"x":200,"y":146},{"x":192,"y":146},{"x":199,"y":141},{"x":208,"y":139},{"x":217,"y":139}],"mouth":[{"x":170,"y":209},{"x":175,"y":214},{"x":180,"y":218},{"x":187,"y":219},{"x":194,"y":217},{"x":200,"y":213},{"x":204,"y":207},{"x":199,"y":203},{"x":192,"y":201},{"x":186,"y":203},{"x":180,"y":202},{"x":174,"y":205},{"x":175,"y":210},{"x":181,"y":211},{"x":187,"y":211},{"x":193,"y":210},{"x":198,"y":209},{"x":198,"y":207},{"x":193,"y":208},{"x":187,"y":209},{"x":180,"y":207},{"x":175,"y":207}],"nose":[{"x":184,"y":184},{"x":183,"y":160},{"x":180,"y":166},{"x":177,"y":173},{"x":174,"y":180},{"x":170,"y":188},{"x":178,"y":191},{"x":185,"y":192},{"x":192,"y":190},{"x":199,"y":186},{"x":194,"y":179},{"x":191,"y":172},{"x":187,"y":166}]}}],"errorcode":0,"errormsg":"OK"}

忽略掉检测五官位置的数据:

            "face_id": "2188093443753939350",            "x": 128,            "y": 127,            "height": 106,            "width": 106,            "pitch": 6,            "roll": 3,            "yaw": -2,            "age": 23,//年龄 [0~100]            "gender": 94,//性别 [0/(female)~100(male)]            "glass": true,//是否有眼镜 [true,false]            "expression": 34,//微笑[0(normal)~50(smile)~100(laugh)]            "beauty": 80,//魅力 [0~100]
