关于百度ai的人脸检测功能的调用

关于百度ai的人脸检测功能的调用

首先第一步创建一个应用

然后就会得到他的appid，和apikey还有secretkey

第二步确认你的账号是v几的，就要看v几的文档，注意这是个坑，v3以前的少一个image_type的参数

好的，确认所有东西之后，在去看文档，步骤是先用appid，和apikey还有secretkey来获取到access_token，这个东西可以重复用一个月，拿到了之后就可以调接口了。先附上我的代码

工具类，此工具类我是在大佬那里下载的如有侵权请联系删除（是叫工具类嘛，我也不清楚萌新请大佬嘴下留情）

}

附上第二个

ample.demo.Common;import java.io.*;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 (!ists()) {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Bufferbyte[] bbuf = new byte[10240];// 用于保存实际读取的字节数int hasRead = 0;while ( (hasRead = ad(bbuf)) > 0 ) {sb.append(new String(bbuf, 0, hasRead));}fis.close();String();}/*** 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 (!ists()) {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 = ByteArray();return var7;} finally {try {if (in != null) {in.close();}} catch (IOException var14) {var14.printStackTrace();}bos.close();}}}}

然后最重要的图片转成那个啥64格式的，

ample.demo.Common;import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.HttpURLConnection;
import java.URL;import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;/*** Created by zhangwenchao on 2017/9/29.* 本地或者网络图片资源转为Base64字符串*/
public class Base64ImageUtils {/*** @Title: GetImageStrFromUrl* @Description: 将一张网络图片转化成Base64字符串* @param imgURL 网络资源位置* @return Base64字符串*/public static String GetImageStrFromUrl(String imgURL) {byte[] data = null;try {// 创建URLURL url = new URL(imgURL);// 创建链接HttpURLConnection conn = (HttpURLConnection) url.openConnection();conn.setRequestMethod("GET");conn.setConnectTimeout(5 * 1000);InputStream inStream = InputStream();data = new byte[inStream.available()];ad(data);inStream.close();} catch (IOException e) {e.printStackTrace();}// 对字节数组Base64编码BASE64Encoder encoder = new BASE64Encoder();// 返回Base64编码过的字节数组字符串de(data);}/*** @Title: GetImageStrFromPath* @Description: (将一张本地图片转化成Base64字符串)* @param imgPath* @return*/public static String GetImageStrFromPath(String imgPath) {InputStream in = null;byte[] data = null;// 读取图片字节数组try {in = new FileInputStream(imgPath);data = new byte[in.available()];in.read(data);in.close();} catch (IOException e) {e.printStackTrace();}// 对字节数组Base64编码BASE64Encoder encoder = new BASE64Encoder();// 返回Base64编码过的字节数组字符串de(data);}/*** @Title: GenerateImage* @Description: base64字符串转化成图片* @param imgStr* @param imgFilePath  图片文件名，如“E:/tmp.jpg”* @return*/public static boolean saveImage(String imgStr,String imgFilePath) {if (imgStr == null) // 图像数据为空return false;BASE64Decoder decoder = new BASE64Decoder();try {// Base64解码byte[] b = decoder.decodeBuffer(imgStr);for (int i = 0; i < b.length; ++i) {if (b[i] < 0) {// 调整异常数据b[i] += 256;}}// 生成jpeg图片OutputStream out = new FileOutputStream(imgFilePath);out.write(b);out.flush();out.close();return true;} catch (Exception e) {return false;}}
}

接下来附上我获取access_token的代码

@Controller
@RequestMapping("/AI" )
public class FaceAPITest {//获取token@PostMapping("/token")@ResponseBodypublic static void getToKenTest(){//使用其测试百度云API---获取token//url:  APPID ="x"; //管理中心获得//百度人脸识别应用apikeyString API_KEY = "xx"; //管理中心获得//百度人脸识别应用sercetkeyString SERCET_KEY = "xxx"; //管理中心获得//百度人脸识别token 有效期一个月String TOKEN = null;String access_token_url = ".0/token?grant_type=client_credentials"+"&client_id="+API_KEY +"&client_secret="+SERCET_KEY;CloseableHttpResponse response =  HttpClientUtils.doHttpsGet(access_token_url,null);System.out.String(response));String  ACC_TOKEN&#String(response);//得到token &#xxxxxxxxxxxxxxxxxxxxxxxxxxx.2592000.1536458879.282335-11656996}
}

拿到了之后，直接用这东西调取接口

@Controller
@RequestMapping("/AI" )
public class FaceAPITest {//使用token调用API@PostMapping("/recognition")@ResponseBodypublic static String faceDetecttest() throws IOException {String token = &#xxxxxxxxxxxxxxxxxxxxxxx.2592000.1536458879.282335-11656996";String Filepath = "E:"+ File.separator + "deb60dd02a.jpg";/* String Filepath = OriginalFilename();*/String image = Base64ImageUtils.GetImageStrFromPath(Filepath);String url = ".0/face/v3/detect?access_token="+token;Map<String, String> headers = new HashMap<String, String>();headers.put("Content-Type", "application/x-www-form-urlencoded");Map<String, String> bodys = new HashMap<String, String>();String image_type=UUID.randomUUID().toString().replace("-", "");bodys.put("image_type", "BASE64");bodys.put("image", image);bodys.put("face_field","age,beauty,expression");try {CloseableHttpResponse response =HttpClientUtils.doHttpsPost(url,headers,bodys);String jieguo =  String(response);return jieguo;} catch (Exception e) {e.printStackTrace();}return null;}}

好了，返回给前端的是一个，josn字符串，让前端把这个字符串转成js对象，就可以取到了

还有一点要注意这个的参数，是你需要什么，就加什么，具体看百度ai的文档

附上我的maven，其实json那个是没用的，因为我想在后端把json字符串转成对象，然后发现，在前端转比较方便所有就放弃了

附上我的目录

好了，这样就可以拿到颜值了，附上一张我的运行结果

哎呀我颜值还是可以的嘛，百度的这个东西要求非常严格，我找那些明星的照片也不过80多分，证明我还是很可以的嘻嘻
