Ta的回复 ：String img = Base64Util.encode(FaceSearch.getImageFromLocalByUrl("src/1.jpg")); String str=""; try { str = new String(img.getBytes("UTF-8"),"UTF-8"); } catch (UnsupportedEncodingException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } try { Map map = new HashMap<>(); map.put("image", str); map.put("liveness_control", "NORMAL"); map.put("group_id_list", "face_data"); map.put("image_type", "BASE64"); map.put("quality_control", "NONE");   img的格式需要这样处理一下哦，我也一直遇到问题，今天解决了
