我这边是用JAVA的服务端做的请求

https://api.ai.qq.com/fcgi-bin/face/face_getinfo

String line = "https://api.ai.qq.com/fcgi-bin/face/face_getinfo?"+params;

URL url = new URL(line);

URLConnection conn = url.openConnection();

InputStream is = conn.getInputStream();

Scanner sc = new Scanner(is,"UTF-8");

返回的是

{ "ret": -31, "msg": "system busy, please try again later", "data": { "person_id": "", "person_name": "", "tag": "", "face_ids": [ ], "group_ids": [ ] } }
