问上传文件到COS遇到的问题？

public static boolean sendCos(String key, String filePath) {
  boolean isSuccess = false;
  try {
    File localFile = new File(filePath);
    PutObjectRequest putObjectRequest = new PutObjectRequest(ResourceCosConfig.bucketName, key,
        localFile);
    logger.info(
        "begin to upload, time is " + System.currentTimeMillis() + "===putObjectRequest==="
            + JSONObject.toJSONString(putObjectRequest));
    COSCredentials cred = new BasicCOSCredentials(ResourceCosConfig.secretId,
        ResourceCosConfig.secretKey);
    Region region = new Region(ResourceCosConfig.region);
    ClientConfig config = new ClientConfig(region);
    config.setSocketTimeout(ResourceCosConfig.timeout);
    config.setMaxConnectionsCount(ResourceCosConfig.httpNum);
    config.setHttpProtocol(HttpProtocol.https);
    COSClient cosClient = new COSClient(cred, config);
    PutObjectResult putObjectResult = cosClient.putObject(putObjectRequest);
    logger.info("result is: " + putObjectResult.getContentMd5() + ", "
        + putObjectResult.getDateStr() + ", " + putObjectResult.getETag() + ", "
        + putObjectResult.getExpirationTimeRuleId()
        + ", " + putObjectResult.getExpirationTime() + ", " + putObjectResult.getRequestId()
        + ", "
        + putObjectResult.getVersionId() + ", " + putObjectResult.getMetadata());
    logger.info("end to upload, time is " + System.currentTimeMillis());
    isSuccess = true;
  } catch (CosServiceException serverException) {
    logger.warn("链接不上cos:", serverException.getMessage());
  } catch (CosClientException clientException) {
    logger.error("clientException:[{}]", clientException.getMessage());
  } catch (Exception e) {
    logger.warn("", e);
  }
  return isSuccess;
}
