这个是在java上调用api接口老是出现权限问题，但是已经自己申请过了，第一次使用不知道怎么修改了，知道的大佬麻烦帮看下，谢谢
// 百度API管理的应用
private static final String App_ID = "14635879";
private static final String API_Key = "scoi5dk8gW1oZLP9B2xmw1Vm";
private static final String Secret_Key = "UgI6dMLBtj7a09DYBP96zwfOI0xNhpEN";
@Autowired
private DoctorService doctorService;
/**
* 用于登录时根据用户名查询出相应照片路径，进行登录比较
* @throws IOException
*/
@RequestMapping("/doctorlogin.do")
//存在返回值添加此注解
@ResponseBody
public String login(HttpServletRequest req, HttpServletResponse resp) throws IOException {
// 获取网页前端发送过来的请求中的数值
//req.setCharacterEncoding("utf-8");
// 获取前端(网页)中拍摄的照片
String faceWeb = req.getParameter("face");
String name=req.getParameter("userName");
System.out.println(name);
System.out.print(faceWeb);
System.out.println();
//调用DoctorService类中的登录方法，查询到相应的用户
Doctor doctor = doctorService.DoctorLogin(name);
System.out.println(doctor);
//faceDB主要用于存放数据库中取出的用户照片信息
String faceDB = "";
// map1用于存放结果和用户信息，result用于存放map转化后的json字符串
HashMap map1 = new HashMap();
String result = null;
if(doctor!=null){
// 将用户名、密码存入session中
HttpSession session = req.getSession();
session.setAttribute("doctorlogin", true);
// 将用户信息存入session
session.setAttribute("Doctor", doctor);
// 获取到面部信息
faceDB = doctor.getD_doctorPicture();
System.out.println(faceDB);
// 调用(百度大脑)百度AI人脸识别接口
AipFace aipFace = new AipFace(App_ID, API_Key, Secret_Key);
// 创建装换对象(把图片转为二进制数组)
BASE64Decoder decoder = new BASE64Decoder();
byte[] Web = decoder.decodeBuffer(faceWeb);
byte[] Db = decoder.decodeBuffer(faceDB);
byte[][] bytes = { Web, Db };
System.out.println(Web);
System.out.println(Db);
// 调用方法进行对比
JSONObject Contrastresult = aipFace.match(bytes, new HashMap());
System.out.println(Contrastresult.toString());
// 获取评分结果result中的score的值
JSONArray jsonArray = Contrastresult.getJSONArray("result");
double score = jsonArray.getJSONObject(0).getDouble("score");

错误信息在哪亲？接口成功失败都会返回JSON格式的字符串内容。你发你的代码没用
