1. 獲取token
package org.fh.util; import org.json.JSONObject; import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; import java.util.List; import java.util.Map; /** * 說明:獲取百度人臉識別token類 * 作者:F-H * from:www.fhadmin.cn */ public class AuthService { /** * 獲取權限token * @return 回傳示例: * { * "access_token": "24.460da4889caad24cccdb1fea17221975.2592000.1491995545.282335-1234567", * "expires_in": 2592000 * } */ public static String getAuth() { // 官網獲取的 API Key 更新為你注冊的 String clientId = "xxxx"; // 官網獲取的 Secret Key 更新為你注冊的 String clientSecret = "ssss"; return getAuth(clientId, clientSecret); } /** * 獲取API訪問token * 該token有一定的有效期,需要自行管理,當失效時需重新獲取. * @param ak - 百度云官網獲取的 API Key * @param sk - 百度云官網獲取的 Securet Key * @return assess_token 示例: * "24.460da4889caad24cccdb1fea17221975.2592000.1491995545.282335-1234567" */ public static String getAuth(String ak, String sk) { // 獲取token地址 String authHost = "https://aip.baidubce.com/oauth/2.0/token?"; String getAccessTokenUrl = authHost // 1. grant_type為固定引數 + "grant_type=client_credentials" // 2. 官網獲取的 API Key + "&client_id=" + ak // 3. 官網獲取的 Secret Key + "&client_secret=" + sk; try { URL realUrl = new URL(getAccessTokenUrl); // 打開和URL之間的連接 HttpURLConnection connection = (HttpURLConnection) realUrl.openConnection(); connection.setRequestMethod("GET"); connection.connect(); // 獲取所有回應頭欄位 Map<String, List<String>> map = connection.getHeaderFields(); // 遍歷所有的回應頭欄位 for (String key : map.keySet()) { System.err.println(key + "--->" + map.get(key)); } // 定義 BufferedReader輸入流來讀取URL的回應 BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); String result = ""; String line; while ((line = in.readLine()) != null) { result += line; } /** * 回傳結果示例 */ JSONObject jsonObject = new JSONObject(result); String access_token = jsonObject.getString("access_token"); return access_token; } catch (Exception e) { System.err.printf("獲取token失敗!"); e.printStackTrace(System.err); } return null; } }
2.人臉對比
package org.fh.util; import java.util.*; import net.sf.json.JSONObject; /** * 說明:人臉對比 * 作者:F-H * from:www.fhadmin.cn */ public class FaceMatch { public static String faceMatch(List<Object> list) { // 請求url String url = "https://aip.baidubce.com/rest/2.0/face/v3/match"; try { String param = GsonUtils.toJson(list); // 注意這里僅為了簡化編碼每一次請求都去獲取access_token,線上環境access_token有過期時間, 客戶端可自行快取,過期后重新獲取, String accessToken = AuthService.getAuth(); String result = HttpUtil.post(url, accessToken, "application/json", param); return result; } catch (Exception e) { e.printStackTrace(); } return null; } //PHOTODATA1 圖片1的 base64碼 //PHOTODATA2 圖片2的 base64碼 回傳的score大于80 說明是同一個人 public static String getScore(String PHOTODATA1,String PHOTODATA2) { List<Object> list = new ArrayList<Object>(); Map<String,String> map1 = new HashMap<String,String>(); map1.put("image", PHOTODATA1); map1.put("image_type", "BASE64"); map1.put("face_type", "LIVE"); map1.put("quality_control", "NONE"); map1.put("liveness_control", "NONE"); list.add(map1); Map<String,String> map2 = new HashMap<String,String>(); map2.put("image", PHOTODATA2); map2.put("image_type", "BASE64"); map2.put("face_type", "LIVE"); map2.put("quality_control", "NONE"); map2.put("liveness_control", "NONE"); list.add(map2); String resultStr = FaceMatch.faceMatch(list); JSONObject jsonMsg = JSONObject.fromObject(resultStr); String error_msg = jsonMsg.getString("error_msg"); String score = "0"; if("SUCCESS".equals(error_msg)) { String result = jsonMsg.getString("result"); JSONObject jsonResult = JSONObject.fromObject(result); score = jsonResult.getString("score"); } return score; } }
