checkUpdate static method

Future<String> checkUpdate(String userId, String protocolVersion, String packageName, String moduleVersion, String language,)

版本更新 userId app用户id protocolVersion 协议版本，目前暂定为1 packageName 当前应用的包名固定com.maxims moduleVersion 当前应用版本号，由前缀”maxims_”加上版本号组合而成，比如应用版本号是v1.0.0，那么实际传入的是maxims_v1.0.0 language 语言 zh-中文 en-英文

Implementation

    'reqSource': '1',
  };
  int timestamp = DateTime.now().millisecondsSinceEpoch;
  String randomStr = CipherUtil.generateRandomString(6);
