• 获取前端上传参数返回给前端，

  callbackBody可自动自定义参数在回调接口接收

public static Map getUploadParams(String userId) {

        OSSClient client = new OSSClient(END_POINT, ACCESS_KEY_ID, ACCESS_KEY_SECRET);
        try {
            long expireTime = 30;
            long expireEndTime = System.currentTimeMillis() + expireTime * 1000;
            Date expiration = new Date(expireEndTime);

            PolicyConditions policyConds = new PolicyConditions();
            policyConds.addConditionItem(PolicyConditions.COND_CONTENT_LENGTH_RANGE, 0, 1048576000);
            policyConds.addConditionItem(MatchMode.StartWith, PolicyConditions.COND_KEY, FILE_DIR);
            String postPolicy = client.generatePostPolicy(expiration, policyConds);
            byte[] binaryData = postPolicy.getBytes(StandardCharsets.UTF_8);
            String encodedPolicy = BinaryUtil.toBase64String(binaryData);
            String postSignature = client.calculatePostSignature(postPolicy);
            Map respMap = new LinkedHashMap<>();
            respMap.put("accessid", ACCESS_KEY_ID);
            respMap.put("policy", encodedPolicy);
            respMap.put("signature", postSignature);
            respMap.put("dir", FILE_DIR);
            respMap.put("host", HOST);
            String name = UUIDGenerator.getUUID(8) + "_";
            respMap.put("name", name + TimeUtils.getCurrentTime() + ".png");
            respMap.put("expire", String.valueOf(expireEndTime / 1000));
            JSONObject jasonCallback = new JSONObject();
            jasonCallback.put("callbackUrl", CALLBACK_URL);
            Map map = new HashMap<>();
            map.put("userId", userId);
            map.put("fileUrl", FILE_DIR + name + TimeUtils.getCurrentTime() + ".png");
            jasonCallback.put("callbackBody", JSON.toJSONString(map));
            jasonCallback.put("callbackBodyType", "application/json");
            String base64CallbackBody = BinaryUtil.toBase64String(jasonCallback.toString().getBytes());
            respMap.put("callback", base64CallbackBody);
            System.out.println(JSON.toJSONString(respMap));
            return respMap;
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
            return null;
        }
    }

• 回调接口 ：返回给前端的参数写在这里

public JSONObject callBack(JSONObject jsonObject) {

            String userId = jsonObject.getString("userId");
            log.setOriginalUrl(imageUrl);
            log.setUserId(userId);
            log.setDateline(TimeUtils.getCurrentUnixTime());
            RestResult restResult = AliYunOSSUtils.portraitSplit(imageUrl);
            if (restResult.getCode() != 200) {
                result.put("message", restResult.getMessage());
                result.put("status", "err");
                log.setErrMsg(restResult.getMessage());
                return result;
            }
            JSONObject object = JSONObject.parseObject(restResult.getData().toString());
            log.setResult(object.toJSONString());
            String requestId = object.getString("requestId");
            log.setRequestId(requestId);
            JSONObject dataObject = object.getJSONObject("data");
            System.out.println("dataObject=" + dataObject);
            JSONArray elArray = dataObject.getJSONArray("elements");
            System.out.println(elArray.size());
            if (elArray.size() > 1) {
                System.out.println("请上传单人照片进行识别");
                result.put("message", "请上传单人照片进行识别");
                result.put("status", "err");
                log.setErrMsg(restResult.getMessage());
                return result;
            }
            JSONObject o = (JSONObject) elArray.get(0);
            String url = o.getString("imageURL");
            String splitUrl = AliYunOSSUtils.uploadImageWithUrl(url, imageUrl);
            Long w = o.getLong("width");
            Long h = o.getLong("height");
            Long x = o.getLong("x");

            log.setSplitUrl(splitUrl);
            log.setWidth(w);
            log.setHeight(h);
            log.setX(x);
            log.setY(y);
            portraitSplitLogService.add(log);

        }
        return result;
    }
