一、成爲開發者

百度ai官網地址：http://ai.baidu.com/java

STEP1：點擊百度AI開放平臺導航右側的控制檯，點擊須要使用的AI服務項，使用百度帳號登陸。如還未持有百度帳戶，能夠點擊此處註冊百度帳戶。
STEP2：首次使用，登陸後將會進入開發者認證頁面，請填寫相關信息完成開發者認證。注：(如您以前已是百度雲用戶或百度開發者中心用戶，此步可略過。)
STEP3：進入具體AI服務項的控制面板（如文字識別、人臉識別），進行相關業務操做。web

2. 建立應用

建立好帳號後，在正式調用AI能力以前，須要您建立一下應用，這個是調用服務的基礎能力單元，不可或缺哦。在百度雲控制檯，已默認爲您免費開通百度語音、文字識別、人臉識別、天然語言處理、圖像審覈、知識圖譜服務六項服務。您能夠選擇您須要的服務，進入對應服務的控制檯中。進入某個服務的控制檯後，您將首先見到此服務的控制檯概覽頁（以人臉識別爲例），以下圖所示，點擊建立應用：express

點擊上圖中的「建立應用」，便可進入應用建立界面，以下圖所示：json

點擊建立就會生成一個應用，包含API Key和SecretKey，這兩個字段是獲取accessToken的依據，是調用api接口的必備字段：api

三、獲取簽名數組

獲取accessToken：經過調用接口：https://aip.baidubce.com/oauth/2.0/token?
    grant_type=client_credentials&
    client_id=Va5yQRHlA4Fq4eR3LT0vuXV4&
    client_secret= 0rDSjzQ20XUj5itV7WRtznPQSzr5pVw2&獲取；緩存

四、進行開發服務器

首先須要下載開發必須用到的jar文件，引入項目：網絡

而後編寫調用接口的編碼，其中用到的文件操做，base64編碼處理以及http請求相關的util文件，百度都已經封裝好，能夠直接使用：socket

package com.hengyunsoft.face.aip;

import java.net.URLEncoder;

import com.baidu.aip.util.Base64Util;
import com.hengyunsoft.face.util.AuthService;
import com.hengyunsoft.face.util.FileUtil;
import com.hengyunsoft.face.util.HttpUtil;

/**
* 人臉探測
*/
public class FaceDetect {

    /**
    * 重要提示代碼中所需工具類
    * FileUtil,Base64Util,HttpUtil,GsonUtils請從
    * https://ai.baidu.com/file/658A35ABAB2D404FBF903F64D47C1F72
    * https://ai.baidu.com/file/C8D81F3301E24D2892968F09AE1AD6E2
    * https://ai.baidu.com/file/544D677F5D4E4F17B4122FBD60DB82B3
    * https://ai.baidu.com/file/470B3ACCA3FE43788B5A963BF0B625F3
    * 下載
    */
    public static String detect(String filePath) {
        // 請求url
        String url = "https://aip.baidubce.com/rest/2.0/face/v1/detect";
        try {
            // 本地文件路徑
            byte[] imgData = FileUtil.readFileByBytes(filePath);
            String imgStr = Base64Util.encode(imgData);
            String imgParam = URLEncoder.encode(imgStr, "UTF-8");

            String param = "max_face_num=" + 5 + "&face_fields=" + "age,beauty,expression,faceshape,gender,glasses,landmark,race,qualities" + "&image=" + imgParam;

            // 注意這裏僅爲了簡化編碼每一次請求都去獲取access_token，線上環境access_token有過時時間， 客戶端可自行緩存，過時後從新獲取。
            String accessToken = AuthService.getAuth();

            String result = HttpUtil.post(url, accessToken, param);
            System.out.println(result);
            return result;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

}

調用測試接口，查看輸出結果，測試一張圖片中的人臉檢測個數：

 public static void main(String[] args) {
        //testDetect1();
        //測試人臉檢測
        String path = System.getProperty("user.dir")+"\\image\\person3.jpg";
        FaceDetect.detect(path);

    }
