protobuf的使用(二)

message Error {
	int32 errorCode = 1;
	bytes errorMsg = 2;
}

message User {
	bytes name = 1;
	int32 age = 2;
	enum Sex {
		MAN = 0;
		WOMAN = 1;
	}
	Sex sex = 3;
}

message GetUserList {
	Error error = 1;
	repeated User list = 2;// repeated表示列表
}

int main() {
  GetUserList p;
  Error* err = p.mutable_error();
  err->set_errorcode(1);
  err->set_errormsg("xxx");

  User* user = p.add_list();
  user->set_age(10);
  user->set_name("zhangsan");
  user->set_sex(User::MAN);

  cout << p.list_size() << endl;
  return 0;
}
